What is type 1 diabetes?
In a person with type 1 diabetes, the pancreas does not produce enough insulin to regulate the blood sugar (glucose) level properly. Insulin is a hormone that reduces blood glucose levels by stimulating the body to utilize glucose for energy. Type 1 diabetes is caused by an abnormal immune system, which normally fights infection. The immune system mistakenly attacks cells in the pancreas, and the damaged cells are unable to produce insulin. The lack of insulin causes elevated blood glucose levels. Type 1 diabetes usually starts during childhood, whereas type 2 diabetes usually begins in adulthood. About 15 out of every 100,000 people develop type 1 diabetes every year in the US.

What are the symptoms of type 1 diabetes?
Symptoms of type 1 diabetes include blurry vision, dizziness, excessive fatigue, excessive thirst, faintness, frequent urination, headaches, muscle cramps, nausea, excessive sleepiness, and weight loss.

How does the doctor treat type 1 diabetes?
Treatment for type 1 diabetes includes a diabetic diet, monitoring the blood sugar, insulin therapy, weight control, and regular exercise.
