Consistently cold feet, even in warm environments, may signal poor blood flow.

A weakened heart may not pump blood efficiently to the extremities.

2. Swelling (Edema) in Feet and Ankles

Puffy, swollen feet and ankles could be due to fluid retention caused by heart failure.

Often worse at the end of the day or after sitting for long periods.

3. Discoloration (Blue, Purple, or Pale Feet)

A bluish or purplish tinge can signal low oxygen delivery.

Pale or ashen feet may indicate decreased blood flow.

4. Numbness or Tingling

Reduced circulation can cause pins-and-needles or numb sensations.

This may worsen with activity and improve with rest — a possible sign of peripheral artery disease (PAD), often linked with heart disease.
