Diabetes is a condition where the body does not properly process sugar (glucose) for energy. There are three main types of diabetes: type 1, type 2, and gestational diabetes. Type 1 is where the body does not produce insulin and usually develops in childhood. Type 2 is the most common type where the body does not use insulin properly. Gestational diabetes occurs during pregnancy. Symptoms include increased urination, thirst, hunger and fatigue. Treatment involves lifestyle changes like diet and exercise as well as medication and possibly insulin injections. Risk factors include family history, obesity and lack of physical activity. Diabetes poses societal burdens as it is a leading cause of death and disability.
