Clinically, patients can take oral diuretics to remove edema, such as hydrochlorothiazide tablets, furosemide tablets, and torasemide tablets. Edema appears due to water and sodium retention in the body, which may be caused by kidney-related diseases or other etiologies. Therefore, in addition to simple diuretic to reduce edema, medication should be administered according to the specific etiology to prevent aggravation of the disease. Clinically, edema caused by nephritis, nephrotic syndrome, diabetic nephropathy and other diseases are the most common, and further examination of renal function, urinary routine, urine protein quantification and other indicators are needed to understand the condition. In daily life, pay attention to control the salt and water intake to avoid the aggravation of the body burden, and have a lighter diet with low salt and low fat, and eat less spicy and stimulating food.
