Diabetes mellitus is a group of disorders involving inappropriate sugar levels in the blood. This is caused by problems with insulin production or activity. Diabetes mellitus occurs in three common forms: type 1, type 2, and gestational diabetes. Type 1 diabetes is a relatively rare disease diagnosed in children and young adults after they develop symptoms. Gestational diabetes, which occurs only in pregnant women, can harm the baby and mother if left untreated. Women who have been diagnosed with gestational diabetes are at increased risk for developing type 2 diabetes in the future. Type 2 diabetes, the most common type, tends to occur in adults during mid or later life, although it can occur in children also. Type 2 diabetes can go unnoticed for many years, so it is important to be screened for type 2 diabetes if you are at high risk.
Here is an assessment tool based on recommendations from the American Diabetes Association to help you determine your risk of type 2 diabetes. This tool is for people who do not have diabetes symptoms. If you have symptoms of diabetes (eg, urinating frequently, always thirsty, numbness or tingling in your hands or feet), see your doctor for an evaluation.
