Full Answer

Symptoms of diabetes include blurred vision, increased thirst, frequent infections, fatigue, extreme hunger, ketones in the urine, irritability and slow-healing sores, explains Mayo Clinic. Type 1 diabetes typically develops during childhood or adolescence, and type 2 commonly appears in people over the age of 40. The cause of type 1 and type 2 diabetes is unknown as of 2015, and gestational diabetes occurs when the hormones produced by the placenta during pregnancy cause cells to become resistant to insulin.

The glycated hemoglobin test, random blood sugar test, fasting blood sugar test and oral glucose tolerance test checks for prediabetes, along with type 1 and type 2 diabetes. The initial glucose challenge test determines gestational diabetes with follow-up glucose tolerance testing. Blood sugar monitoring, insulin, medication, transplantation and bariatric surgery treat type 1 and type 2 diabetes, and blood sugar monitoring, medication and insulin treat gestational diabetes. Maintaining a healthy weight through diet and exercise is crucial to regulating prediabetes.
