First, you need to know what exactly Diabetes is. It is a chronic, potentially incapacitating and often deadly disease. Variable production and supply of insulin in the body is major cause of this disease. Either the body generates no or inadequate insulin (type 1 diabetes), or the body cannot utilize the insulin it produces effectively (type 2 diabetes). Insulin is a hormone made by the pancreas that helps sugar (glucose) to leave the blood and enter the cells of the body to be used as fuel.
