Symptoms
The process that destroys the insulin-producing beta cells can be a long and insidious one. At the point when insulin production bottoms out, however, type 1 diabetes usually appears suddenly and progresses quickly. Warning signs of type 1 diabetes include:
- Frequent urination (in children, a recurrence of bed-wetting after toilet training has been completed)
- Unusual thirst, especially for sweet, cold drinks
- Extreme hunger
- Sudden, sometimes dramatic, weight loss
- Weakness
- Extreme fatigue
- Blurred vision or other changes in eyesight
- Irritability
- Nausea and vomiting (acute symptoms)
Children with type 1 diabetes may also be restless, apathetic, and have trouble functioning at school. In severe cases, diabetic coma may be the first sign of type 1 diabetes.
