Brittle diabetesâalso called labile diabetesâis a rare but serious form of the disease in which there are dramatic and often unpredictable fluctuations in blood sugar levels. Blood sugar naturally rises and falls throughout the day in response to meals, exercise and other factors.
Because monogenic diabetes is rare, this diagnosis is often not considered in people with diabetes. However, certain factors can make doctors suspect that a diagnosis of type 1 or type 2 diabetes is not correct.n most forms of the disease, the body is less able to make insulin, a hormone that helps the body use glucose (sugar) for energy. Rarely, the problem is severe insulin resistance, a condition in which the body cannot use insulin properly. A correct diagnosis can help people get the right treatment.
