What are the symptoms of Type 1 Diabetes?

Insulin is a hormone that converts sugar, starches and other food into energy. In Type 1 diabetes, the lack of insulin can cause sugar to builds up in the bloodstream, where it can cause life-threatening complications.

Symptoms of Type 1 diabetes include:


  • Frequent urination
  • Increased thirst
  • Increased hunger
  • Weight loss
  • Seizures or episodes of unconsciousness
  • Increased tiredness
  • Long term damage to organs such as eyes and joints

What causes Type 1 Diabetes?

The exact cause of Type 1 diabetes is unknown. However it is believed that the presence of certain genes indicates an increased risk of developing type 1 diabetes, and anyone with a parent or sibling with type 1 diabetes has a slightly increased risk of developing the condition. Exposure to Epstein-Barr virus, mumps virus or cytomegalovirus may trigger the autoimmune destruction of the islet cells, or the virus may directly infect the islet cells.
