Diabetes is a metabolic disease caused by a lack of insulin (a
hormone) in the human body. Insulin is needed by the body to
metabolize (breakdown) the sugar that we eat. When insulin is not
available the sugar levels in the body can rise to extremely high
levels which can cause diseases of various body parts like the
kidneys, eyes, nerves, hearts etc.
Many people with type 2 diabetes have no symptoms, and it is often
discovered accidentally after routine medical check ups or when you
are being screened for something else.
