Common Causes of Swollen Feet and Ankles
Swelling in feet and ankles can stem from various causes including pregnancy, injuries, blood clots, and medication side effects. Recognizing these factors helps in timely treatment. Always consult a healthcare professional for proper diagnosis and management of swelling issues.

Swelling in the feet and ankles can arise from multiple reasons and is not exclusive to a specific illness or symptom. While common, this condition often results from fluid retention or edema within the body. Key factors contributing to swollen feet and ankles include injuries, blood clots, pregnancy-related issues, and certain medications or drugs. Let’s explore these causes in detail below:
- Pregnancy-related swelling:
During pregnancy, additional weight increases pressure on your lower limbs, which can lead to swelling in your feet, ankles, and legs. Sudden or severe swelling should prompt a visit to the doctor, as it may signal preeclampsia, a serious condition.
- Injuries to the ankle:
If you injure, sprain, or hurt your ankle, swelling often occurs as part of the body's response to injury. The severity of swelling depends on the extent of the injury, with ankle sprains being common.
- Blood clots:
Blood clots develop when blood flow through veins is obstructed. A clot in the leg can prevent blood from returning to the heart, leading to swelling in the feet or ankles. Medical attention is crucial if a blood clot is suspected.
- Side effects of medications:
Certain medications may cause foot and ankle swelling as a adverse effect. These include:
- Hormonal therapies
- Calcium channel blockers like nifedipine
- Corticosteroids such as prednisone and anabolic steroids
- Diabetes medications
- Antidepressants
Consulting a healthcare professional is essential to address these side effects appropriately.
