Swelling that shows up in your feet, ankles, hands, or belly is called edema. It happens when fluid builds up in tissues faster than your body can remove it. Sometimes it’s temporary and harmless — like after a long flight. Other times it flags a medical issue that needs attention.
Edema can come from many things. Sitting or standing for long periods lets gravity pull fluid into your legs. Poor vein function (venous insufficiency) does the same. Heart, kidney, or liver problems can all cause more serious, widespread swelling. Injuries and infections can create local swelling too.
Certain medicines can cause or worsen edema. A common example is calcium channel blockers used for high blood pressure and angina — nifedipine often causes ankle swelling. Nonsteroidal anti-inflammatory drugs (NSAIDs), some steroids, and some diabetes drugs can also increase fluid retention. If swelling starts after a new medication, tell your doctor; changing the drug or dose might fix it.
Simple actions help a lot. Raise swollen legs above heart level for 20 minutes a few times daily. Wear compression stockings if your doctor approves; they push fluid back up the leg. Cut down on salt — less sodium means less retained water. Move regularly: short walks and calf exercises improve circulation. If you sit a lot, flex your ankles and stand every hour.
Monitor your weight and how tight rings or shoes feel. A sudden gain of a few pounds or new shortness of breath needs prompt medical review. Don’t ignore one-sided leg swelling, which could signal a blood clot (deep vein thrombosis).
If home steps aren’t enough, doctors have tests and treatments. Blood tests can check kidney and liver function. An ultrasound looks for clots or vein problems. For heart-related edema, treatments target the heart; diuretics (water pills) can help remove extra fluid but should be used under medical supervision. Treating the root cause — whether heart, kidney, liver, or vein disease — is the key to long-term control.
When should you seek urgent care? Go to the ER if swelling comes on fast and is paired with chest pain, severe shortness of breath, fainting, or a very painful, red, warm leg. Otherwise, make an appointment with your primary care doctor if swelling persists more than a few days, keeps getting worse, or affects daily life.
Edema is common and often manageable. Small changes — less salt, moving more, using elevation or compression — can cut swelling and improve comfort. If you’re unsure what’s causing your edema or if you take medicines that might be the trigger, talk to your healthcare provider for a clear plan.
