- Diabetes is a metabolic disease that causes high blood sugar. The hormone insulin moves sugar from the blood to cells to be stored or used for energy.
- With diabetes, body either doesn’t make enough insulin or can’t effectively use the insulin it does make.
- Untreated high blood sugar from diabetes can damage nerves, eyes, kidneys, and other organs.
Different types of diabetes:
- Type 1 diabetes:It is an autoimmune disease. The immune system attacks and destroys cells in the pancreas, where insulin is made. It’s unclear what causes this attack. About 10 percent of people with diabetes have this type.
- Type 2 diabetes: It occurs when body becomes resistant to insulin, and sugar builds up in your blood.It stems from a combination of genetics and lifestyle factors.
- Pre-diabetes: It occurs when blood sugar is higher than normal, but it’s not high enough for a diagnosis of type 2 diabetes.
- Gestational diabetes:It is high blood sugar during pregnancy. Insulin-blocking hormones produced by the placenta cause this type of diabetes.
Diabetes affects the five major organs namely, Kidney, Heart, Blood vessels, Nervous System, and Eyes (retina).
