(HealthDay News) -- Low-dose aspirin therapy helps lower the risk of heart attack in many people, but it isn't for everyone.

The American Diabetes Association says you should avoid aspirin therapy if:

  • You have an allergy to aspirin.
  • You bleed easily.
  • You've had recent bleeding in the digestive tract.
  • You have active liver disease.
  • You are younger than age 21.

The association says you should check with your doctor to determine if aspirin therapy is safe for you.
