Diabetes is a complaint that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Both men and women may witness the following symptoms of undiagnosed diabetes. Diabetes mellitus is a complex metabolic disorder characterized by hyperglycemia that results from defects in insulin secretion, insulin action, or both. In 2017, there were 451 million adult people with DM globally, a prevalence expected to rise dramatically in the coming decades. Studies have shown that sub-Saharan African countries, including Ethiopia, are experiencing a surge in the prevalence of DM resulting from rapid demographic, sociocultural, and economic transitions. Based on a national survey, researchers have recently reported a DM prevalence of 3.2% (3.5% males and 3.0% females) in Ethiopia. Type 2 diabetes-a global epidemic of our century-accounts for more than 90-95% of DM disease.
