Diabetes is a chronic condition associated with abnormally high levels of sugar (glucose) in the blood.
Symptoms of diabetes include increased urine output, thirst and hunger as well as fatigue. Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas to normalize the glucose level. The absence or insufficient production of insulin causes hyperglycaemia with people suffering from diabetes. It’s a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
