Maturity-Onset Diabetes of the Young (MODY) is a form of diabetes that typically appears in adolescents or young adults, often before the age of 25. It is caused by a genetic mutation that affects insulin production in the pancreas. Unlike Type 1 diabetes, which is an autoimmune condition, or Type 2 diabetes, which is often linked to lifestyle factors, MODY is inherited and can be passed down through families. There are several types of MODY, each associated with different genetic mutations. Diagnosis usually involves genetic testing to identify the specific type, which can help guide treatment. Management may include lifestyle changes, oral medications, or insulin therapy, depending on the type and severity of the condition.
