Depending on the cause, some tips that may help reduce swelling in the legs include raising the legs above heart level when lying down, consuming a low-salt diet, and wearing support stockings, explains MedlinePlus. Additionally, losing weight if needed, exercising the legs, and avoiding tight clothing may also help.
Sometimes, medications can cause swelling in the legs, feet or ankles, states MedlinePlus. However, it is important never to stop taking medications without speaking to a physician. Some types of medications that can contribute to swelling include hormones such as estrogen and testosterone, blood pressure medications and antidepressants. Swollen legs can also be a sign of a serious medical condition such as kidney failure, heart failure and liver failure, which causes fluid accumulation in the body.
Additional potential causes of swelling in the legs include a blood clot, being overweight, an infection and aging, explains MedlinePlus. Sometimes, veins in the legs cannot efficiently pump blood back to the heart and this can also cause swelling. See a doctor for swelling accompanied by a fever or the swollen leg is red or warm. Individuals with kidney or liver failure who have an increase in swelling should also see a physician. Call 911 for shortness of breath or chest pain.
