(HealthDay News) -- Aspirin is often recommended by cardiologists for its blood-thinning properties, but the medication can lead to complications, including stomach problems.

The Cleveland Clinic says you should always check with your doctor before starting a daily aspirin regimen.

In general, the clinic says, people at risk for the following conditions may benefit from aspirin therapy:

• Heart attack.
• Blood clots or stroke caused by blood clots.
• Unstable angina.
• Transient ischemic attacks (TIAs) or "mini-strokes."
