Swelling in both legs can sometimes indicate that the heart is not pumping blood effectively. When circulation slows down, fluid may build up in the lower body.

This type of swelling may be accompanied by:

• Chest discomfort

Persistent swelling linked to breathing difficulties should be evaluated immediately.

• Abdominal swelling
