Symptoms of diabetes

Frequent urination, excessive thirst, unexplained weight loss, and becoming increasingly tired and ill are the typical symptoms of high blood sugar.

Adults can be misdiagnosed as having type 2 diabetes because of a lack of knowledge that type 1 diabetes can start at any age. If diet, exercise, and oral medication are not keeping blood sugars under control, an endocrinologist can test for anti-GAD antibodies (which are present in type 1 diabetes) and fasting C-peptide levels (which measure how much insulin the pancreas is producing) to determine if someone has type 1 or type 2 diabetes.
