Type 2 diabetes is a disorder that disrupts the way your body processes sugar.
Your body processes sugar with the help of a hormone called insulin. If there is not enough insulin, or if the body stops responding to insulin, or both, sugar does not get processed and builds up in the blood.
Sometimes no symptoms
