Swelling in the feet, ankles, or legs—medically called edema—can sometimes be harmless, but it can also signal underlying health issues. Here’s what it could mean:
Common Causes of Foot Swelling
- Fluid Retention
- Can happen from standing or sitting too long, high salt intake, or hot weather.
- Heart Problems
- Swollen feet may indicate congestive heart failure, where the heart doesn’t pump efficiently and fluid backs up in the lower body.
- Kidney Issues
- Impaired kidney function can cause fluid to accumulate in the body, including feet and ankles.
- Liver Disease
- Conditions like cirrhosis reduce the liver’s ability to manage fluid, leading to swelling.
- Venous Insufficiency
- When veins can’t properly return blood to the heart, fluid pools in the feet and ankles.
- Medication Side Effects
- Some drugs, like blood pressure medications, steroids, or anti-inflammatory drugs, can cause swelling.
- Injury or Infection
- Sprains, fractures, or infections can cause localized swelling.
- Pregnancy
- Hormonal changes and increased pressure on veins often cause swelling in the feet and ankles.
Red Flags
Seek medical attention if swelling is:
- Sudden or severe
- Painful or red
- Accompanied by shortness of breath, chest pain, or fatigue
What You Can Do
- Elevate your feet when sitting or sleeping
- Reduce salt intake
- Wear compression socks if recommended by a doctor
- Stay active to improve circulation
⚠️ Key takeaway:
Swollen feet can sometimes be harmless, but persistent or sudden swelling can signal heart, kidney, or liver problems, and it’s important to get evaluated by a healthcare professional.
