If your feet are swollen, it is recommended that you take rest, soak your feet in warm water, and observe whether the swelling subsides. If it is caused by poor venous return, the swelling can be reduced by the above treatment. If it still cannot be reduced, it is recommended to further clarify the cardiac function, renal function, liver function, thyroid function and other tests. If it is caused by poor cardiac function, it will be aggravated after activity and alleviated after rest. It can be alleviated by cardiotonic and diuretic treatments, as well as oral furosemide, spironolactone and other diuretic drugs. If it is caused by renal diseases, such as nephritis, it is recommended to treat it by preserving kidney, and intermittent application of diuretics can reduce edema. If it is caused by nephrotic syndrome, it is recommended to apply immunosuppressant. If the edema is obvious, intravenous infusion of human albumin can be used to expand the volume of treatment, and then diuretic drug treatment. If it is caused by abnormal thyroid function, thyroid hormone supplementation is needed.
