What are the symptoms of type 1 diabetes?

There are many different symptoms of type 1 diabetes. These generally develop over a short period of time. Without enough insulin, your body will start to draw fluid from the tissues to compensate for the buildup of sugar. Therefore, this may cause an increase in thirst, urination, hunger, weight loss, tiredness, and blurred vision.

When first diagnosed, most people with type 1 diabetes have typical symptoms of diabetes plus very high blood glucose levels. Typical symptoms of type 1 diabetes are:

- frequent urination
- extreme thirst
- extreme hunger
- unexplained weight loss
- fatigue
- blurry vision
- frequent infections
- nausea or vomiting

Symptoms of type 1 diabetes usually develop over a short period, although beta-cell destruction can begin years earlier. Symptoms include increased thirst and urination, constant hunger, weight loss, blurred vision, and extreme fatigue. If not diagnosed and treated with insulin, a person with type 1 diabetes can lapse into a life-threatening diabetic coma, also known as diabetic ketoacidosis.
