To eliminate swollen feet quickly and effectively, the cause of the swelling should be identified and then treated accordingly. The most common causes of swollen feet are heart failure, hepatic failure and renal failure, as well as malnutrition, thyroid disease, hypoplasia or thrombosis of the veins of the lower extremities. Treatment includes application of drugs, surgical treatment, etc. Drugs should be applied under the guidance of a doctor. 1. Heart failure: it is mainly seen in right heart failure, which is characterized by body circulation stasis, and the patient likes to sit, which leads to lower limb edema. At the same time, patients with total heart failure is also very common. Need to give cardiac drugs such as digoxin, cediran, diuretics such as furosemide and other comprehensive treatment, serious cases need to be hospitalized. 2. Hepatic failure: impaired liver function leads to a decrease in plasma protein formation in the liver, resulting in edema, which is mostly manifested as fluid in the abdominal cavity, and in severe cases, can lead to edema of the lower limbs. According to the condition, it is necessary to take hepatoprotective and diuretic treatment, such as the use of various traditional Chinese medicines to protect the liver tablets, silymarin tablets, compound glycyrrhizin tablets and other diuretics such as furosemide treatment. 3. Glomerulonephritis and nephrotic syndrome can lead to renal failure, which can form swelling of the feet. Kidney disease requires immunosuppressive therapy such as prednisone acetate and cyclophosphamide. 4. Insufficient thyroxine secretion and hypothyroidism after thyroid disease or total amputation surgery can lead to swollen feet, which need to be treated with oral levothyroxine sodium tablets. 5. Lower extremity venous valve insufficiency or lower extremity venous thrombosis, leading to lower extremity blood transportation obstacles and thus the formation of edema. You can wear compression stockings, take medication such as herbaceous rhinoceros infusion tablets, and surgery if necessary. 6. Malnutrition: it leads to the decrease of plasma protein concentration and the edema of the lower limbs. Therefore, it is necessary to supplement nutrition.
