Diabetes, Type 1

Diabetes is a long-term (chronic) disease. It occurs when the cells in the pancreas that make insulin (a hormone) are destroyed and can no longer make insulin. Type 1 diabetes was also previously called juvenile-onset diabetes. It most often occurs before the age of 30, but it can also occur in older people.

CAUSES

Among other factors, the following may cause type 1 diabetes:

  • Genetics. This means it may be passed to you by your parents.

  • The beta cells that make insulin are destroyed. The cause of this is unknown.

SYMPTOMS

  • Urinating more than usual (or bed-wetting in children).

  • Drinking more than usual.

  • Irritability.

  • Feeling very hungry.

  • Weight loss (may be rapid).

  • Nausea and vomiting.

  • Abdominal pain.

  • Feeling more tired than usual (fatigue).

  • Rapid breathing.

  • Difficulty staying awake.

  • Night sweats.
