Type 1 diabetes

Type 1 diabetes – previously known as insulin dependent or juvenile diabetes – is an autoimmune disease that occurs when the pancreas is no longer able to produce the insulin needed, because the cells that produce the insulin have been destroyed by the body’s immune system.

Usually diagnosed in childhood, teen and young adult years, type 1 diabetes can occur at any age. Lifestyle choices don’t cause type 1 diabetes.

Symptoms of Type 1 diabetes

People with type 1 diabetes usually have sudden onset of symptoms, which may include:

  • Going to the toilet frequently to pass urine
  • Excessive thirst and drinking a lot of fluids
  • Unexplained weight loss
  • Fatigue (tiredness)
  • Mood changes
  • Skin infections
  • Oral or vaginal thrush
  • Abdominal pain
  • Excess hunger
  • Weakness
  • Irritability

Type 1 is managed with insulin injections several times a day, or through the use of an insulin pump

Type 1 diabetes is NOT:

• Caused by eating too much sugar or by having a bad diet
• Curable – once diagnosed, you have the disease for life
• Your fault – there is no way to prevent type 1 diabetes
• Contagious – you can’t catch it from another person
