What is Diabetes?

 

Diabetes mellitus is a metabolic disorder in which the body's capacity to utilize glucose, fat and protein is disturbed due to insulin deficiency and/or insulin resistance.

In people with diabetes there is insufficient insulin activity in the body. Insulin is a hormone produced by beta cells of islets of Langerhans in the pancreas.

 

Action of Insulin on the food

 

Most of the food we eat is broken down into glucose and other simple sugars. Glucose gets absorbed into the blood stream which enters into the cells and is used for energy. As the blood glucose rises, insulin is released from the pancreas. Cells have receptor sites on the outside. When insulin attaches to the receptor sites, a passage is made and glucose enters into the cell. This insulin regulates the blood glucose level.

When there is insulin deficiency, glucose cannot enter into the cells and remain in the blood which leads to high blood sugar levels. 

 

Normal Blood Glucose Levels

 

            Fasting              80 – 120 mg/dl

            Post Prandial   120 – 160 mg/dl

 

Insulin deficiency may be relative or absolute and may be due to

 

  •   Insufficient production of insulin by the pancreas.
  •   Sufficient production of insulin but non-release into the blood stream.
  •   Increased demand of insulin by the body tissues.
  •   Destruction / Inactivation of insulin by enzymes and other factors produced by the liver and endocrine glands such as pituitary gland, adrenal cortex thyroid etc. 
  •  

Symptoms of Diabetes

  •   Increased thirst
  •   Increased hunger
  •   Frequent urination
  •   Weight loss
  •   Weakness and tiredness
  •   Delayed wound healing
  •   Numbness in hands and feet
  •   Blurred vision
  •   Itching in genitals

 

Risk Factors for Diabetes

  •   Individual with positive family history of diabetes
  •   Over weight individuals
  •   Person who has high blood pressure or hyperlipidemia
  •   Those with previous bad obstetric history

  Recurrent abortions

  Still birth

  Congenital malformation

  Big baby (over 3.5 kg at birth)

  •   Those under mental stress
  •   Physically inactive people (sedentary jobs)

Classification of Diabetes

 

Diabetes refers to a condition in which there is elevated blood sugar. It is a chronic disorder of metabolism where the body is not able to effectively utilize the blood sugar. Diabetes can be classified as follows:

 

  • Type 1 Diabetes (or)
    Insulin Dependant Diabetes Mellitus (IDDM)
  •  
  • Type 2 Diabetes (or) Non-insulin Dependant
    Diabetes Mellitus (NIDDM)
  •  
  • GDM-Gestational Diabetes Mellitus.
  •  
  • FCPD-Fibrocalculous Pancreatic Diabetes.
  •  

There are other rare conditions of diabetes associated with genetic syndromes. Drugs and toxic metabolites can also induce secondary diabetes. The other specific types of diabetes are:

  • Diabetes due to genetic defect in the beta cell function. E.g., - Maturity Onset Diabetes of youth. (MODY)
  • Diabetes due to a genetic defect of insulin action.
  •  

Type 1 Diabetes (IDDM)

 

This type of diabetes results from complete destruction of beta cells of the pancreas due to auto immunity which results in the absence of insulin secretion.  Such patients need insulin treatment for their survival. On withdrawal of insulin, they end up with high blood sugar finally resulting in diabetic ketoacidosis.

Type 1 diabetes is generally found in young children, adolescents and adults under the age of 40 years. The onset of symptoms is usually sudden, and the major symptoms observed are:

  • Increased thirst and appetite.
  • Excessive urination.
  • Fever and sudden weight loss.

In some cases, patients present with keto-acidosis or coma especially during recurrent illness or surgery.

 

Causes

 

Genetic factors, autoimmune and environmental factors play a role in the causation of this kind of diabetes.

 

Type 2 Diabetes ( NIDDM)

 

This type is very common and is widely known as Non- insulin Dependant Diabetes.  It develops in later stages of life. Often patients are overweight, (some may be lean due to loss of weight because of uncontrolled diabetes) and have family history of diabetes. They may respond to diet, exercise and oral hypoglycemic drugs. Their symptoms develop gradually and many have insulin resistance.

 

Causes

 

  • Genetic factors (family history).
  • Environmental factors such as obesity lack of physical activity, stress and drugs such as steroids.
  •  

Common symptoms

 

  • Excessive thirst, hunger and urination
  • Loss of weight
  • Tiredness
  • Irritability
  • Pruritis (itching)- often in the private parts
  • Burning feet, tingling or numbness of feet
  •  

Differences between Type 1 and Type 2 Diabetes

 

 

   Type 1 Diabetes or IDDM

 

   Type 2 Diabetes or NIDDM

 

  • Life long dependency

on insulin

 

Can be treated with diet,

exercise and oral drugs

 

  • Usually detected below 20 years of age

 

Usually detected above 25

years of age.

 

  • Negative family.

history of diabetes

 

About 60% have a positive family history

 

  • Diabetic coma occurs

if insulin is stopped

 

Diabetic coma is rare

 

Gestational Diabetes (GDM)

 

GDM is a condition where the diabetes sets in during pregnancy. The assessment for GDM should be undertaken at the first prenatal visit. Women with obesity, previous history of GDM, glycosuria or family history of delivering big babies should undergo a spot random glucose screening.  If  they are found to have elevated blood sugars during the initial screening, they should undergo a glucose tolerance test.  If they are normal, they can be retested between 24 and 28 weeks of their gestation.

Patients can be treated with diet control in mild cases and insulin may be needed if the sugars are high. Oral hypoglycemic drugs are contraindicated during pregnancy 5 % of patients may continue to have diabetes after delivery.

 

Impaired Glucose Tolerance (IGT)

 

The term IGT refers to a metabolic stage intermediary between normal glucose tolerance and diabetes.  IGT is more frequent in obese than in non-obese persons. They may be associated with an increased frequency of hypertension, hyperlipidemia, obesity and fasting hyprinsulinemia.  About 3-5 % of  the patients with IGT progress to diabetes every year. Those with IGT are advised to be on diet control, exercise and adopt life style changes to prevent diabetes.

 

Fibrocalculous Pancreatic Diabetes (FCPD)

 

This is an unique secondary type of diabetes occurring due to pancreatic stones. The whole pancreatic gland is shrunken due to pancreatitis and hence the insulin producing cells are damaged, resulting in diabetes. These patients are usually very lean, malnourished and may present with severe abdominal pain prior to developing diabetes. They usually require insulin to control their diabetes.

  • Improve the quality of life
  •  
What exercise dose for the heart?
 
  • Improves blood circulation
  • Strengthens the heart
  • Lowers blood pressure
  • Increase HDL/ (good cholesterol)
  • Decrease LDL (bad cholesterol)
 
Smart and safe exercise
 
  • Consult your doctor before beginning exercise programme.
  • Always carry a diabetic identity card.
  • Stay alert for signs of low blood sugar during or several hours after exercise.
  • Have rapidly absorbable carbohydrate sources ready like sugar, glucose and candy.
  • Monitor blood sugar before and after the exercise.
  • Take carbohydrate snacks if blood glucose levels are less than 100 mg/dl.
  • Drink plenty of fluids before and after and if necessary during exercise to avoid dehydration.
  •  
How often, How much and How long
 

Try to do exercise every day, minimum of 5 days a week.

Intensity ….. moderate intensity.

  • Start slowly and work up gradually every week.
  • Brisk walking of 5-6 km/hour should be reached.
 
Time
 

Time should last for at least 30 minutes going up to one hour if possible. There should be a warm up and cool down period of exercise for each session.

 
Warm up
 

Prepares body for vigorous activity; helps Prevent strains and injuries to muscles. It should last for 5-10 minutes.

 
Cool down
 

Helps restore circulation to normal levels, prevents cramps, sore muscles and post – exercise dizziness. This should last for 5 to 10 minutes.

 
Choose Your Exercise

  • Elderly people or those with long standing diabetes should not do weight lifting.
  • Avoid strenuous exercise or vigorous sports during the first few months of pregnancy. Walking and swimming are good.
  • To prevent hypoglycemia after strenuous exercise, eat some carbohydrate containing foods.
  •  
Tips for increasing exercise in daily life
 
  • Choose a longer route while walking.
  • Walk to the store instead of using a vehicle.
  • Use steps instead of taking the elevator.
  • If you are in sedentary job, try to stretch out for few minutes every hour and take a short Walk within the office whenever possible.
 
When should you stop exercise

Holidays and Travel

 

Having diabetes does not mean you have to restrict your holiday or travel plans. As with everything else, a little pre-planning makes things easier. Here is some basic information you need to know.

 

Car travel

 

Car travel usually means (traffic jams permitting) you can stop when you like, but do make sure you have some food available in the car. Start your day early so that you can arrive at your destination early. Always have some form of sugar in the car with you because hypoglycemia is particularly dangerous when you are driving. Choose something that won't melt and mess up the upholstery in your car.

 

Train Travel

 

Train travel means you may be subject to delay. Again, carry food and drinks with you. Bread, biscuits (sugar free biscuits are now available) and fruits would stay longer and hence can be had during travel.

 

Air Travel

 

Most airlines provide food very frequently, but do carry extra in case of delays. Since you will not be doing much exercise and will probably be more stressed than usual, you could be slightly sugary for few days. This will do you no harm and at least you can be fairly confident that you will not become hypoglycemic particularly on long journeys. It is wise to request the cabin staff to provide some food if you feel meals are getting usually delayed.

 

Travel Abroad

 

If you are on a package tour, please note that the travel insurance is likely to exclude "pre-existing conditions" which means, diabetes in your case. For customs purposes, particularly in exotic places, a letter from your clinic explaining why you are carrying syringes and needles is also a good idea. Please note that some of the pen injectors show up on the metal detector at airports. You are likely to have to take it out and explain that it is not a weapon.

 

Travel Tips

 

  • Always carry and wear medical identification that says that you have diabetes.
  • Keep medication, insulin and syringes readily available in your carry on luggage.
  • Carry prescriptions for medications, syringes and blood glucose testing supplies.
  • Plan ahead for changes in meal times (especially when you are crossing time / zones). Plan times for testing your blood glucose.
  • Carry food and some form of fast acting carbohydrates (e.g., sugar).
  • Find out how and where to obtain emergency medical help.
  • Follow your meal plan and your activity routine.
  • Take your medications as prescribed by your doctor.
  • Test your blood glucose regularly, test more frequently if you are ill.
  • Check carefully that your own insurance covers diabetic emergencies for your holiday.
  • Discuss the implications of different units of insulin with your diabetologist.
  • Discuss also the effects of time zones and change of lifestyle with your health care team.
  • When sunbathing, or relaxing in the heat, be aware of hypoglycemic episodes, or dehydration due to the heat. Drink plenty of water.
  • During a swim, access to fast acting carbohydrate should be available, in case of hypoglycemia. Ensure that you eat prior to swimming.
  • Take warm clothing with you when traveling to cold destinations. Make sure your insulin does not freeze.
  • Always wear well fitting sandals for leisure on the beach and when swimming.
  • Wherever possible learn the basics in the local language, e.g., "I am diabetic; please give me something sweet to drink; please call a doctor."

Prevention of Diabetes

 

The prevalence of Diabetes Mellitus in the Indian population now ranks first in the world even ahead of China. In the last twenty years there has been a three fold increase in the prevalence of diabetes and today it is estimated that there are over 20 million people with diabetes in India.

The problem in diabetes is that very often it is silent. The symptoms of diabetes such as increased thirst and urination, etc., occur only when the diabetes is severe. In early stages it can remain totally asymptomatic. Moreover after 10-15 years duration of diabetes, the prevalence of all diabetes related complications increase markedly. These include Retinopathy leading to blindness, Nephropathy leading to kidney failure, Heart attacks, Gangrene of the feet, Stroke and even less known complications like Impotency, and sexual weakness. Thus diabetes is a serious threat to public health and this shows the need for prevention of diabetes.

 

Primary Prevention

 

Primary prevention refers to the prevention or the postponement of diabetes itself in those who are susceptible to diabetes. Early detection is the key to prevent and control diabetes. As diabetes is largely asymptomatic, regular screening for diabetes is most important.

 

Why should you be screened for Diabetes?

 

Positive Family History

 

It is a well known fact that diabetes is caused mostly due to hereditary factors. Hence it is clear that screening of diabetic families would be the first priority.

 

Risk of diabetes based on family history:   Risk

 

If both parents are diabetic                                        99%

If one parent is diabetic                                              50%

If any other relative is diabetic                                    20%

One parent diabetic and any other relative

of the non-diabetic parent is also diabetic                  75%

Hence it is clear that anyone who has positive family history should be screened for diabetes.

 

At what age the screening should be started?

 

The onset of diabetes is earlier in Indians i.e., around 20-30 years of age. If the family history is strong, e.g., members of more than two generations in the family have diabetes, the first screening could be done even by 20-25 years of age and thereafter on a yearly or two yearly basis.

 

Obesity

 

Obesity causes resistance to Insulin. Your body makes insulin but the extra weight prevents it form using the insulin the way it should be. For this reason, obesity is another risk factor for diabetes.

 

What test to be done?

 

The Glucose Tolerance Test (GTT) is the confirmatory test since it helps to diagnose even the early stage of diabetes. Most people check only Fasting, Postprandial or Random Blood Sugar which may not reveal diabetes until it is at a more advanced stage. Even if the GTT results show normal values at the time of testing, it does not mean that the person will never develop diabetes. Such individuals should have an annual GTT done if the family history of diabetes is very strong.

 

Secondary Prevention

 

Secondary Prevention refers to the prevention of complications once diabetes set in. This can be achieved by good control of diabetes with the help of diet, exercise, medication and regular monitoring of blood sugars. Blood sugars can be checked even on daily basis with help of blood sugar meters which facilitates quick determination of blood sugars. Since blood sugars tend to fluctuate a lot, from day to day or hour to hour, HbA1C (Glycosylated haemoglobin) test should be done to assess the blood sugar for the previous 2-3 months.

 

Tertiary Prevention

 

Tertiary prevention refers to the rehabilitative measures once the complications have set in. For example, for Diabetic Retinopathy, the technique of Laser Photocoagulation will help to prevent or reduce the incidence of blindness. Laser photocoagulation helps to seal leaking blood vessels in the retina and thus prevent visual loss.

It is recommended that at least once a year every diabetic individual should do a complete checkup of all complications especially the eyes, kidneys, heart and feet in order to reduce the morbidity due to diabetes.

 

LEVELS OF PREVENTION IN DIABETES

 

Symptoms of Diabetes

 

In both types of diabetes, signs and symptoms are more likely to be similar as the blood sugar is high, either due to less or no production of insulin, or insulin resistance. In any case, if there is inadequate glucose in the cells, it is identifiable through certain signs and symptoms. These symptoms are quickly relieved once the Diabetes is treated and also reduce the chances of developing serious health problems.

 

Diabetes Type 1

 

In type 1, the pancreas stop producing insulin due to autuimmune response or possibly viral attack on pancreas. In absence of insulin, body cells don't get the required glucose for producing ATP (Adenosin Triphosphate) units which results into primary symptom in the form of nausea and vomiting. In later stage, which leads to ketoacidosis, the body starts breaking down the muscle tissue and fat for producing energy hence, causing fast weight loss. Dehydration is also usually observed due to electrolyte disturbance. In advanced stages, coma and death is witnessed.

 

Diabetes Type 2

 

  • Increased fatigue: Due to inefficiency of the cell to metabolize glucose, reserve fat of body is metabolized to gain energy. When fat is broken down in the body, it uses more energy as compared to glucose, hence body goes in negative calorie effect, which results in fatigue.
  • Polydipsia: As the concentration of glucose increases in the blood, brain receives signal for diluting it and, in its counteraction we feel thirsty.
  • Polyuria: Increase in urine production is due to excess glucose present in body. Body gets rid of the extra sugar in the blood by excreting it through urine. This leads to dehydration because along with the sugar, a large amount of water is excreted out of the body.
  • Polyphegia: The hormone insulin is also responsible for stimulating hunger. In order to cope up with high sugar levels in blood, body produces insulin which leads to increased hunger.
  • Weight flactuation: Factors like loss of water (polyuria), glucosuria , metabolism of body fat and protein may lead to weight loss. Few cases may show weight gain due to increased appetite.
  • Blurry vision: Hyperosmolar hyperglycemia nonketotic syndrome is the condition when body fluid is pulled out of tissues including lenses of the eye, which affects its ability to focus, resulting blurry vision.
  • Irritability: It is a sign of high blood sugar because of the inefficient glucose supply to the brain and other body organs, which makes us feel tired and uneasy.
  • Infections: The body gives few signals whenever there is fluctuation in blood sugar (due to suppression of immune system) by frequent skin infections like fungal or bacterial or UTI (urinary tract infection).
  • Poor wound healing: High blood sugar resists the flourishing of WBC, (white blood cell) which are responsible for body immune system. When these cells do not function accordingly, wound healing is not at good pace. Secondly, long standing diabetes leads to thickening of blood vessels which affect proper circulation of blood in different body parts.

Types of diabetes

 

There are three main types of diabetes:

 

  • Type 1 diabetes
  • Type 2 diabetes
  • Gestational diabetes (GDM) 

 

Type 1 diabetes

 

Is sometimes called insulin-dependent, immune-mediated or juvenile-onset diabetes. It is caused by an auto-immune reaction where the body's defence system attacks the insulin-producing cells. The reason why this occurs is not fully understood. People with type 1 diabetes produce very little or no insulin. The disease can affect people of any age, but usually occurs in children or young adults. People with this form of diabetes need injections of insulin every day in order to control the levels of glucose in their blood. If people with type 1 diabetes do not have access to insulin, they will die.

 

Type 2 diabetes

 

Is sometimes called non-insulin dependent diabetes or adult-onset diabetes, and accounts for at least 90% of all cases of diabetes. It is characterised by insulin resistance and relative insulin deficiency, either of which may be present at the time that diabetes becomes clinically manifest. The diagnosis of type 2 diabetes usually occurs after the age of 40 but can occur earlier, especially in populations with high diabetes prevalence. Type 2 diabetes can remain undetected for many years and the diagnosis is often made from associated complications or incidentally through an abnormal blood or urine glucose test. It is often, but not always, associated with obesity, which itself can cause insulin resistance and lead to elevated blood glucose levels.

 

Gestational diabetes (GDM)

 

Is a form of diabetes consisting of high blood glucose levels during pregnancy. It develops in one in 25 pregnancies worldwide and is associated with complications in the period immediately before and after birth. GDM usually disappears after pregnancy but women with GDM and their offspring are at an increased risk of developing type 2 diabetes later in life. Approximately half of women with a history of GDM go on to develop type 2 diabetes within five to ten years after delivery.

Tests related to Diabetes

 

The main diagnostic test for diabetes is taking a blood test to measure glucose, either when you have been fasting or at other times of the day. Diagnostic tests are also used routinely done during pregnancy to identify gestational diabetes.

 

High blood sugar levels harm the body

 

The hormone insulin helps to move blood sugars (glucose) into cells and convert glucose into energy. Diabetes is a condition characterized by abnormally high levels of glucose in the blood. This occurs because, either not enough insulin is made, or the cells don't respond to the hormone.

Untreated, high glucose levels can cause serious damage to many parts of the body, including:

 

  • Kidney damage
  • Eye damage
  • Nerve damage to the feet and other parts of the body
  • Heart disease and circulation problems in the legs
  • Stroke
  • Impotence.
  •  

Accuracy of test results

 

Depending on the test used, the level of blood glucose can be affected by many factors including:

 

  • Eating or drinking
  • Taking medications that are known to raise blood sugar levels, such as oral contraceptives, some diuretics (water pills) and corticosteroids
  • Physical illness or surgery that may temporarily alter blood sugar levels.
  •  

Test procedures

 

Most diabetes tests require blood samples. Generally, a band is tightened around your upper arm to slow blood flow and cause the veins below the band to stand out. The intended needle site is swabbed with alcohol. The hypodermic needle is inserted into the vein and the blood is directed into a collection tube. The band may be removed from your arm while the blood is being taken.

You may need more than one collection tube, depending on the test. After the blood is taken, you are asked to press a cotton ball or gauze against the injection site. Once bleeding has stopped, the injection site is covered with a sticking plaster.

 

Types of tests

 

Tests to diagnose diabetes include:

 

  • Fasting blood glucose test– blood glucose levels are checked after fasting for between 12 and 14 hours. You can drink water during this time, but should strictly avoid any other beverage. Patients with diabetes may be asked to delay their diabetes medication or insulin dose until the test is completed.
  • Random blood glucose test– blood glucose levels are checked at various times during the day, and it doesn't matter when you last ate. Blood glucose levels tend to stay constant in a person who doesn't have diabetes.
  • Oral glucose tolerance test– a high-glucose drink is given. Blood samples are checked at regular intervals for two hours.

 

The most common test for diagnosis of diabetes is the fasting blood glucose test. Glucose tolerance tests are used when the results of the fasting blood glucose are borderline. They are also used to diagnose diabetes in pregnancy (gestational diabetes).

 

Immediately after the procedure

 

The fasting blood glucose test will confirm that the person has diabetes if it shows that the level of glucose in their blood is higher than normal when they are fasting.

Sometimes the test result of the fasting blood glucose test is borderline. If this is the case, a glucose tolerance test may be performed. This test will confirm diabetes if the person's blood sugar levels stay high for a long time after the tests.

If a person doesn't have diabetes, the results of the glucose tolerance test will show that their blood sugar levels fall within the normal range.

 

Possible complications

 

Possible complications of diabetes testing include:

 

  • Feeling faint or nauseous at the sight of blood or needles
  • Bleeding and bruising at the injection site
  • Infection of the skin at the injection site
  • Multiple injection sites if collecting the blood is difficult
  • Rarely, a reaction following the oral glucose tolerance test if the patient has diabetes mellitus or hypoglycemia (low blood sugar levels) – medications may be needed.

What is Juvenile Diabetes?

 

Diabetes is a chronic metabolic condition caused by the body's inability to break down glucose (sugars) and store them properly. When an individual's system is unable to efficiently process glucose, it will back up in the person's bloodstream creating multiple health problems.

Over thirty thousand individuals will be diagnosed with diabetes this year alone. It is estimated that over one hundred and twenty million individuals worldwide have diabetes. It is further estimated that approximately five million individuals have diabetes that has yet to be diagnosed.

 

What are the symptoms?


Type 1 Diabetes symptoms include:

--Excessive thirst
--Frequent urination
--Irritability
--Nausea and vomiting
--Exaggerated hunger, although weight loss occurs
--Chronic weakness and fatigue
--Blurred vision

 

Type 2 Diabetes symptoms include:

--Symptoms may appear more subtle but can include type 1 symptoms
--Itchiness
--Tingling or numbness in hands or feet
--Sores that heal slowly
--Recurring bladder infections
--Fatigue
--Blurred vision

 

Without adequate medical treatment and supervision, serious health problems can arise. Long term complications include heart attacks, blindness, nerve damage that can ultimately cause loss of limbs, and kidney failure. It is crucial to follow your physician's treatment plan to avoid serious side effects.

Diabetes and Pregnancy

 

The prevalence of Type-2 diabetes mellitus is higher in women, partly related to obesity. The Type-2 diabetes typically doubles the coronary heart disease risk in men and triples in women.

Diabetes Mellitus in pregnant women poses problems for the mother and the fetus. Women with established diabetes may have menstrual problems and difficulty in conceiving. While, pregnancy itself worsens diabetic control and may cause certain diabetic complications to progress in mother. Maternal diabetes is also hazardous for the fetus and carries an increased risk for fetal loss and major congenital malformations.

However, nowadays most women of child bearing age can realistically expect to become mothers of healthy children with intensive glycemic control. Improvements have ranged from technological advances in fetal surveillance (ultrasound scanning) to home glucose monitoring and intensive insulin regimens, enabling women with multiple diabetic complications to have successful pregnancies.

Diabetes Mellitus in pregnancy is classified into pre-gestational and gestational diabetes; gestational diabetes is defined as diabetes that is discovered during pregnancy. Approximately 7% of all pregnancies are complicated by GDM. Normal pregnancy reduces insulin sensitivity because of diabetogenic effects of placental hormones. This effect is maximal in the late second and third trimester. Gestational diabetes resolves after delivery, but may recur in subsequent pregnancies and the lifetime risk for developing Type-2 diabetes is 30%.

 

Indications for detection of diabetes in pregnant women

 

  • Family history of Diabetes
  • Glucose in urine sample
  • History of unexplained prenatal loss
  • History of large baby
  • History of congenitally malformation infant
  • Maternal obesity
  • Maternal age more than 25 years
  • Members of ethnic/racial group with high prevalence of Diabetes Mellitus
  •  

To prevent excess spontaneous abortion and congenital malformations in infants of diabetic mothers, diabetes care and education must begin before conception. There are no contraceptive methods that are specifically contraindicated in women with diabetes. The selection of a method should focus on its proven high degrees of effectiveness. Once patient achieves stable sugar control then contraception can be discounted and hence, plan for a pregnancy.

 

Management during pregnancy

 

Quit smoking/alcohol
Home blood glucose monitoring
Diet control/Folate supplementation
Regular exercise
Fetal monitoring by ultrasound scan
Accurate insulin regimen

What Is Prediabetes?

 

People with prediabetes have glucose levels that are higher than normal but not high enough yet to indicate diabetes. The condition used to be called borderline diabetes. Most people with pre diabetes don't have symptoms, but they are considered to be at high risk of developing heart disease.

Normally, your body produces a hormone called insulin to help your cells use the energy (glucose) found in food. With diabetes, either your body doesn't make enough insulin or doesn't efficiently use the insulin it does produce. When glucose builds up in the blood, it can damage the tiny blood vessels in the kidneys, heart, eyes, and nervous system.

With prediabetes, the subtle balance between glucose and insulin has been thrown off. The pancreas may not be able to produce enough insulin after a meal to "clear" the incoming glucose from the blood. Or cells may be insulin resistant. When cells are insulin resistant, they won't allow the insulin to escort glucose from the bloodstream into them. Too much glucose in the blood is also called high blood sugar or hyperglycemia. A low blood sugar level is called hypoglycemia.

If you have pre diabetes, you're at high risk of developing type 2 diabetes as well as the serious medical problems associated with diabetes, including heart disease  and stroke. With prediabetes, you are at a 50% higher risk of heart disease and stroke than someone who does not have prediabetes.

 

How is prediabetes diagnosed?

 

To determine if you have prediabetes, your doctor can perform one of three different blood tests – the fasting plasma glucose (FPG) test, the oral glucose tolerance test (OGTT) or the Hemoglobin A1C (or average blood sugar) test.

 

How is the fasting plasma glucose test (FPG) done?

 

The fasting plasma glucose test can be done after an overnight fast or after an eight-hour fast during the day. It is a relatively easy, inexpensive test. After the fast, a simple blood test measures glucose levels before you eat again. The test results indicate whether your blood glucose level is normal or whether you have prediabetes or diabetes:

  • Normal:Normal blood sugar levels measure less than 100 mg/dl (milligrams per deciliter) after the fasting glucose test.
  • Prediabetes:Blood glucose levels of 100-125 mg/dl after an overnight or eight-hour fast may indicate prediabetes. People with these results are considered to have impaired fasting glucose (IFG).
  • Diabetes:Diabetes is diagnosed when the blood glucose is 126 mg/dl or above.

In most cases, your doctor will repeat any abnormal test before confirming the diagnosis.

 

How is the oral glucose tolerance test (OGTT) done?

 

The OGTT usually requires that you have the fasting glucose test first. Then you take a dose of high-sugar (glucose) solution to challenge your body to clear the glucose from your blood. After two hours, another blood glucose test is done. The final test results indicate whether you have a normal level of blood glucose or may have prediabetes or diabetes:

  • Normal:Normal blood sugar levels measure less than 140 mg/dl after the oral glucose tolerance test.
  • Prediabetes:Blood glucose levels of 140-199 mg/dl after the OGTT is diagnosed as prediabetes. People with these results are considered to have impaired glucose tolerance (IGT).
  • Diabetes:Diabetes is diagnosed with blood glucose of 200 mg/dl or above.

Diabetes Complications

 

Once we have crossed the reversible stage of pre diabetes and enter diabetes stage, certain changes start developing in our body. These changes occur due to high blood sugar level with instability in the hormones as well as blood vessels and nerves. When these changes become permanent in the body it develops into serious Diabetes Complications and body indicates these changes by steady symptoms.

 

Symptoms of the Diabetes Complications

 

  • Diabetic retinopathy shows symptoms of pain in the eyes and may even result in loss of vision.
  • Renal (kidney) disease shows symptoms of swelling (edema) in the feet and legs. It then passes over total body and as the disease progresses, blood pressure also increases.
  • Tingling, burning, numbness, tightness, shooting or stabbing pain in the hands, feet or other parts of your body, especially at night. Digestive problems also occur if, the nerves controlling internal organs get damaged (autonomic neuropathy).
  • You may have scanty or profuse sweating, difficulty of sensing when your bladder is full, when there is a low blood sugar, increased sexual problems, weakness, dizziness, and fainting.
  • Chest pain(angina) or shortness of breath dizziness or light headache, shoulder or stomach pain, fast heartbeat. You might not show any symptoms until having a heart attack or stroke.

 

When alarming symptoms given by the body are ignored and the same status is maintained, it starts damaging body organs, such as heart, kidney, eye, feet, and skin. The physiology for each and every affected organ is explained one by one.
