What is Diabetes??? What causes Diabetes???

Diabetes is a lifelong condition in which the body does not produce or properly use insulin, a hormone needed to control the conversion of food into energy. When starchy or sugary foods are eaten and digested, they are broken down into glucose, a natural sugar which is used to meet the body’s energy requirements.

Insulin helps to maintain levels of glucose in the blood, ensuring they are not too high or too low, but remain well within a normal range of 4-7 milimoles of glucose per litre of blood. Insulin acts like a key, allowing glucose into the body’s cells where it is used as energy for normal cell activity. The body not producing enough insulin, or not using it properly, is equivalent to not having keys, or having keys that do not work. The result of this is an accumulation of glucose in the blood.

At present there is no cure for diabetes but it can be managed by maintaining a healthy lifestyle, (including diet and exercise) and taking appropriate medication.

There are 3 main types of diabetes

1. Type 1 Diabetes:

Type 1 Diabetes, which happens when the pancreas does not make any insulin at all. It is more common in adolescents and young adults, accounting for about 5-15% of all diabetes cases. Treatment involves dietary education as well as insulin replacement via injections, pumps or inhalers.

2. Type 2 Diabetes:

Type 2 Diabetes, which is the most prevalent type of diabetes, accounts for more than 85-95% of all diabetes cases and is more common in adults and the elderly.  It develops when the pancreas does not make enough insulin, or if there is insulin resistance – a situation where there is sufficient insulin but it is not recognized. Treatment involves dietary education, and in most cases, tablets and/or insulin.

3. Gestational Diabetes:

Gestational Diabetes occurs in pregnancy when the body cannot meet the increased demand for insulin caused by the growing baby hormones your body makes. When this happens, blood glucose levels rise above normal. Treatment of gestational diabetes is usually by dietary education and if that fails, it is insulin. Whilst this type of diabetes disappears after delivery, there is an increased risk of developing Type 2 diabetes later in life.
