Swelling in the feet, ankles, or legs—also called edema—can happen for many reasons. While it’s sometimes harmless, it can also signal underlying health issues. Here’s a breakdown:
Common Causes of Foot Swelling
- Prolonged Standing or Sitting
- Gravity causes fluid to pool in the lower extremities.
- Often temporary and improves after elevating your feet.
- Injury or Infection
- Sprains, fractures, or infections can cause localized swelling, redness, or warmth.
- Pregnancy
- Hormonal changes and increased pressure on veins can lead to swelling.
- Heart Problems
- Congestive heart failure can cause fluid buildup, often starting in the feet and ankles.
- Kidney Issues
- Impaired kidney function can cause fluid retention throughout the body.
- Liver Disease
- Liver problems can lead to low protein in the blood, causing fluid leakage into tissues.
- Medications
- Certain drugs (like blood pressure meds, steroids, or hormone therapy) can cause swelling.
- Venous Insufficiency
- Weak veins in the legs fail to return blood efficiently, causing fluid to accumulate.
💡 Red Flags:
Seek medical attention immediately if swelling is sudden, painful, accompanied by shortness of breath, chest pain, or redness/heat—these could indicate serious heart, kidney, or vascular issues.
