Swelling in the hands and feet, known as peripheral edema, is common but can signal underlying health issues. It occurs when excess fluid builds up in tissues, often due to increased blood pressure, blood chemistry changes, or injuries. Persistent swelling may indicate serious problems.

Common causes include heart failure, which hampers blood pumping and causes fluid buildup, often with symptoms like shortness of breath and fatigue; kidney disorders that impair fluid regulation, sometimes with urine changes and fatigue; liver diseases such as cirrhosis that increase pressure and cause swelling; venous insufficiency and lymphedema, affecting blood flow and lymph drainage; hormonal changes or medications causing water retention; infections or inflammation resulting in localized swelling; and allergic reactions that may affect limbs and other areas.

Seek medical attention if swelling is sudden, severe, or accompanied by chest pain, difficulty breathing, skin changes, signs of infection, or swelling that doesn’t improve with elevation. These signs may indicate urgent conditions requiring prompt care.

Doctors diagnose the cause through medical history, physical exams, blood tests, urine analysis, and imaging studies like ultrasound or echocardiography. Managing swelling involves lifestyle changes such as elevating limbs, reducing salt, exercising, and medications like diuretics. Compression therapy, treating infections, and controlling chronic conditions are also important.

If swelling appears suddenly or worsens with other symptoms, seek immediate care to prevent serious complications. Recognizing that swelling can be a warning sign helps in early diagnosis and treatment, promoting better health and well-being.
