There are two different types of diabetes:
Type 1 diabetes – In type 1 diabetes, the pancreas does not make insulin or makes very little insulin.
Type 2 diabetes – In most people with type 2 diabetes, the body stops responding to insulin normally. Then, over time, the pancreas stops making enough insulin. Type 2 diabetes is a disorder that disrupts the way your body uses sugar. It is sometimes called type 2 diabetes mellitus.
All the cells in your body need sugar to work normally. Sugar gets into the cells with the help of a hormone called insulin. Insulin is made by the pancreas, an organ in the belly. If there is not enough insulin, or if your body stops responding to insulin, sugar builds up in the blood. That is what happens to people with diabetes.
Being overweight or having obesity increases a person's risk of developing type 2 diabetes. But people who are not overweight can get diabetes.
Pancreas is a gland behind the stomach which is in responsible for insulin secretion.(figure 1)
It secrets juice for digestion to the gut as well as inulin for blood sugar control in the blood.
The most common symptoms of diabetes are polyuria and polydypsia but it can be silent, that is why we recommend routine regular blood test as the screening method.
