WHAT IS DIABETES?

Diabetes is a lifelong disease in which the body cannot process sugar properly. Diabetes is also called diabetes mellitus or sugar diabetes. When people who have diabetes eat glucose, which is found in foods such as breads, potatoes and sweets, it can’t be converted into energy. Instead of being converted into energy, the glucose stays in the blood. This is why people who have diabetes have blood sugar (glucose) that is too high.

Your blood needs to always contain sugar as available energy. But too much sugar is not good for your health as it may damage your heart, kidneys, eyes, nerves, teeth and gums.

THE TWO COMMON TYPES OF DIABETES

  • Type 1 diabetes

This is commonly diagnosed in children, teenagers and young adults. People with this type of diabetes do not produce insulin and therefore need to take insulin injections every day.

  • Type 2 diabetes

This is the most common type of diabetes. People with this type of diabetes cannot use insulin well and therefore need to take tablets or insulin. People who are overweight and inactive have increased risk of developing type 2 diabetes.

HOW DO I KNOW IF I HAVE DIABETES?

You may have one or more of the symptoms below or there may be no symptoms at all. It is advisable to visit your doctor so that he/she can decide on the appropriate test for testing your blood sugar.

The symptoms of high blood sugar are:

  • being very thirsty
  • passing urine more often, even at night
  • feeling hungry or tired more often
  • losing weight without trying to
  • having sores that heal very slowly
  • having dry and itchy skin
  • losing feeling in your feet or feeling a tingling sensation in your feet
  • having blurry vision

TESTS DONE FOR DIABETES

  • Blood sugar (glucose)
    Your blood sugar can be tested following an overnight fast (the blood is tested first thing in the morning before eating and drinking anything). Your doctor may however choose to test a random blood sugar level that can be drawn anytime without prior fasting.
  • Glucose tolerance test (GTT)
    This is also known as a glucose loading test. For this test you need to fast overnight and have the test done before you eat anything in the morning. A blood sugar sample is taken first, before you are given a solution
    mixed with 75g sugar to drink. You need to stay seated for the duration of the test. A second blood sugar sample is drawn at the end of a two hour period after you ingested the solution.
  • HbA1c
    You do not have to fast to do this test. This test may be used for both diagnosis as well as monitoring of diabetes. This test represents time-averaged highs and lows of your blood sugar over a period of three to four months.
  • Urine micro-albumin
    This test is done in the urine. It is the earliest way of testing for the presence of complications caused by diabetes i.e. end-organ damage like kidney disease. This test is also used to estimate the severity of renal disease as a complication of diabetes.
  • Lipogram
    Total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides form part of a standard lipogram. These lipids are used to estimate the risk of heart disease (heart attack).

EATING PLAN FOR TYPE 2 DIABETES

  • Eat three balanced meals a day, not more than six hours apart. Limit added sugars and sweets.
  • Eat a variety of vegetables and fruit each day.
  • Eat your fruit rather than drinking it as juice.
  • Include whole-grain starchy foods at each meal.
  • Choose low-GI foods.
  • Drink water instead of a fizzy or fruit drink.
  • Always choose lean protein at each meal.
  • Make low-fat choices and cut down on added on fat, particularly saturated fats (butter, margarine and cheese).
  • Include beans and lentils in your diet.
  • If you choose to drink alcohol, do so only in moderation.
  • Reduce your salt intake.
  • Move your body for at least 30 minutes every day, for example, by walking.
  • If you are overweight, aim to lose five to 10 percent of your present weight.
