Ankle swelling is what causes

Ankle swelling may be caused by factors such as standing for a long time, malnutrition, varicose veins of the lower limbs, nephritis, heart failure, etc. 1. Standing for a long time for a long time will lead to poor venous return of the lower limbs, poor local microcirculation, thus causing edema in the ankle. 2. Malnutrition Due to the lack of potassium or other essential nutrients in the body, the balance of fluid inside and outside the cell is out of balance, causing fluid retention in the tissue gap. This swelling may be accompanied by general fatigue, lack of spirit and other symptoms. 3. Varicose veins of the lower limbs When varicose veins of the lower limbs are damaged, the venous valve function is impaired, and blood return is blocked, resulting in increased venous pressure, and fluid exudes into the tissue gap causing swelling. Venous thrombosis may completely block venous return channels, resulting in distal limb swelling. 4. Nephritis nephritis can cause glomerular filtration function damage, resulting in water and sodium retention in the body, causing systemic edema, ankle as a lower part of the lower limbs, edema is particularly obvious. 5. Heart failure Heart failure, heart pumping function weakened, blood stasis in the venous system, especially lower limb veins, will lead to increased venous pressure, fluid exudation into the tissue gap caused by edema. once ankle swelling is found, symptoms should be observed in time and medical examination to determine the cause and treatment.
