Diabetes is a group of diseases in which the body doesn’t produce enough or any insulin, doesn’t properly use the insulin that is produced, or exhibits a combination of both. When any of these things happens, the body is unable to get sugar from the blood into the cells. That leads to high blood sugar levels.
Glucose, the form of sugar found in your blood, is one of your main energy sources. A lack of insulin or resistance to insulin causes sugar to build up in your blood. This can lead to many health problems.
The three main types of diabetes which are:
Type 1 diabetes
Type 1 diabetes is believed to be an autoimmune condition. This means your immune system mistakenly attacks and destroys the beta cells in your pancreas that produce insulin. The damage is permanent.
What prompts the attacks isn’t clear. There may be both genetic and environmental reasons. Lifestyle factors aren’t thought to play a role.
Type 2 diabetes
Type 2 diabetes starts as insulin resistance. This means your body can’t use insulin efficiently. That stimulates your pancreas to produce more insulin until it can no longer keep up with demand. Insulin production decreases, which leads to high blood sugar.
The exact cause of type 2 diabetes is unknown. Contributing factors may include:
• lack of exercise
• being overweight
There may also be other health factors and environmental reasons.
Gestational diabetes is due to insulin-blocking hormones produced during pregnancy. This type of diabetes only occurs during pregnancy.
