In people who have symptoms, PAD may cause:
PAD can lead to severe problems, such as:
- Critical limb ischemia —Ulcers that are slow to heal because of low or blocked blood flow. They can lead to gangrene. When the blood supply is cut off, the tissue does not get enough oxygen and begins to die. Gangrene can lead to amputation of the limb.
- Functional decline —As PAD progresses, you won't be able to walk as far.
- Erectile dysfunction
