What Your Legs Can Reveal About Your Overall Health: Understanding the Signs Your Body May Be Sending

Understanding what these signs could mean doesn’t replace medical advice, but it can help you recognize when it’s time to seek an evaluation.

Swollen Legs and Ankles

Swelling in the lower legs or ankles is common after long periods of standing, sitting, or traveling. However, swelling that appears suddenly, becomes severe, or affects only one leg may signal a more serious issue.

Possible causes include:

• Fluid retention
• Venous insufficiency
• Heart, kidney, or liver conditions
• Certain medications
• Blood clots (which require immediate medical attention)

If swelling is accompanied by chest pain, shortness of breath, or significant pain in one leg, seek emergency medical care.
