1. Cold feet or toes
Persistently cold feet, even in warm environments, may indicate poor blood circulation.
A weakened heart cannot pump blood effectively to the extremities.
2. Swelling (edema) in the feet and ankles
Swollen and inflamed feet and ankles can be due to fluid retention caused by heart failure.
Often worse at the end of the day or after sitting for a long time.
3. Discoloration (blue, purple, or pale feet)
A bluish or violet hue may indicate low oxygen supply.
Pale or ashy feet may indicate reduced blood circulation.
4. Numbness or tingling
Reduced blood flow can lead to tingling or numbness.
This can worsen with increased activity and improve at rest – a possible sign of peripheral arterial disease (PAD), which is often associated with heart disease.
5. Wounds or sores that don't heal
Poor blood circulation can prevent the body from healing even small cuts.
Chronic ulcers or slow-healing wounds on the feet are a warning sign, especially in diabetics.
