What is maturity-onset diabetes of the young (MODY)?

Maturity-onset diabetes of the young (MODY) usually affects young adults, but can also affect teens and children. It can be misdiagnosed as type 1 in younger patients. Adults with MODY develop diabetes at a younger age than most type 2 patients and do not tend to be overweight or sedentary. In the past, people with MODY were often told they had a form of type 2 diabetes. We now know that MODY is caused by a genetic mutation that leads to impaired insulin secretion. Insulin resistance, which is often found in type 2 diabetes, does not usually occur in MODY. If you have MODY, you may be able to manage your blood glucose levels through diet and exercise alone, at least for a while. However, therapies that work for people with type 2 diabetes do not always work for people with MODY. You may have more success with insulin therapy or oral agents that stimulate insulin secretion.
