E10: Type 1 diabetes mellitus

Type 1 diabetes mellitus is a chronic medical condition that affects the body's ability to regulate blood sugar levels. It is characterized by the insufficient production of insulin - a hormone needed to convert sugar and other foods into energy - as a result of an autoimmune reaction where the body's immune system attacks and destroys insulin-producing cells in the pancreas. Symptoms often come on quickly and may include increased thirst and urination, unexplained weight loss, fatigue, and blurred vision. If left uncontrolled, the high blood sugar caused by Type 1 diabetes can lead to long-term complications, such as heart disease, kidney damage, nerve damage, and vision problems. This condition typically begins in childhood or adolescence, but can develop at any age. The etiology of Type 1 diabetes is not completely understood, but it is thought to involve a combination of genetic and environmental factors.
