Peripheral edema

Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system, usually in the lower limbs. In the most dependent parts of the body (those hanging distally), it may be called dependent edema.

Leg edema

The condition is commonly associated with aging, but can be caused by many other conditions, including congestive heart failure, renal failure, liver cirrhosis, portal hypertension, trauma, alcoholism, altitude sickness, pregnancy, hypertension, sickle cell anemia, compromised lymphatic system, or merely long periods of time sitting or standing without moving.[1] Some medicines (e.g. amlodipine, pregabalin) may also cause or worsen the condition.[2]

Prognosis

Successful treatment depends on control of the underlying cause. Severe swelling can cause permanent damage to nerves, resulting in peripheral neuropathy. Many cases from temporary or minor causes resolve on their own, with no lasting damage.[2]
