Diabetes is a prevalent chronic condition that places high demands on the individual's immune system. Diabetes is classified into three types: type 1 diabetes, type 2 diabetes, and gestational diabetes. Type 1 Diabetes Mellitus is caused by the auto-immune loss of the pancreas' insulin-producing beta cells. Auto-antibody testing and the C-peptide test can distinguish type 1 diabetes from type 2 diabetes. Diabetes type 1 accounts for 10% of all diabetic patients. Diabetes Mellitus Type 2 is a metabolic condition characterised by insulin resistance and a lack of insulin.
