Diabetes mellitus is a metabolic disorder characterised by high blood sugar (glucose) levels. The condition results from the body’s inadequate production of insulin or the body’s altered response to insulin, or both. Diabetes causes abnormally high glucose levels (hyperglycemia), circulatory problems, and nerve damage. Diabetes cannot be cured, but it can often be managed with proper medical care, diet, and regular exercise. There are two types of Diabetes, Type 1 and Type 2. Approximately 90% of all diabetes cases are Type 2.
