Neonatal diabetes mellitus (NDM) and maturity-onset diabetes of the young (MODY) are the two main forms of monogenic diabetes. NDM occurs in newborns and young infants. MODY is much more common than NDM and usually first occurs in adolescence or early adulthood. Most cases of monogenic diabetes are incorrectly diagnosed. For example, when high blood glucose is first detected in adulthood, type 2 diabetes is often diagnosed instead of monogenic diabetes.
Low blood glucose, also called low blood sugar or hypoglycemia, occurs when the level of glucose in your blood drops below what is healthy for you. For many people with diabetes, this means a blood glucose reading lower than 70 milligrams per deciliter (mg/dL). Your number might be different, so check with your doctor or health care team to find out what blood glucose level is low for you.
