Type 1 diabetes: Know the symptoms & risk factors

Type 1 diabetes can develop at any age, but it is usually diagnosed in children, teens and young adults.

It is less common than type 2 diabetes – only about 5 percent of people with diabetes have type 1.

According to the CDC, type 1 diabetes is thought to be caused by an autoimmune reaction that destroys cells in the pancreas that make insulin. While there is not a known way to prevent type 1 diabetes, it can be managed.

Health officials say untreated diabetes can lead to very serious health problems and even death.

The CDC shared these symptoms and risk factors to be aware of:


  • Urinate (pee) a lot, often at night
  • Are very thirsty
  • Lose weight without trying
  • Are very hungry
  • Have blurry vision
  • Have numb or tingling hands or feet
  • Feel very tired
  • Have very dry skin
  • Have sores that heal slowly
  • Have more infections than usual
  • May have nausea, vomiting, or stomach pains

Risk factors

  • Having a family history – parent, brother, or sister—with type 1 diabetes
  • More likely to be developed as a child, teen or young adult; but it can occur at any age

If you believe you or your loved one may have diabetes, see your doctor. A blood test can help determine if you have diabetes.

Type 1 diabetes can be managed with the help of your doctor. According to the CDC, those with type 1 diabetes will need to take insulin shots, check their blood sugar regularly, and follow a healthy lifestyle.
