Around 1.6 million people in the UK have diabetes – and the number is growing. It’s a condition where the pancreas can’t control blood sugar, leading to a higher than normal level in the body. Type 1 diabetes and Type 2 diabetes are the two major forms.
What is diabetes?
Diabetes is a disorder of metabolism — the way our bodies use digested food for growth and energy. Most of the food we eat is broken down into glucose, the form of sugar in the blood. Glucose is the main source of fuel for the body.
After digestion, glucose passes into the bloodstream, where it is used by cells for growth and energy. For glucose to get into cells, insulin must be present. Insulin is a hormone produced by the pancreas, a large gland behind the stomach.
When we eat, the pancreas automatically produces the right amount of insulin to move glucose from blood into our cells. In people with diabetes, however, the pancreas either produces little or no insulin, or the cells do not respond appropriately to the insulin that is produced. Glucose builds up in the blood, overflows into the urine, and passes out of the body. Thus, the body loses its main source of fuel even though the blood contains large amounts of sugar.
What are the types of diabetes?
The three main types of diabetes are;
- type 1 diabetes
- type 2 diabetes
- gestational diabetes
