It is possible to use diuretics for edema, but only under the supervision of a doctor. The accumulation of water in the subcutaneous tissue is called edema. According to the distribution of edema can be divided into two categories: systemic and local; according to the cause of the disease can be divided into cardiogenic edema, renal edema, malnutritional edema and so on. Diuretics include furosemide, hydrochlorothiazide, spironolactone, etc. These drugs can be used for symptomatic treatment of edema. It should be noted that the side effects of diuretics include hypokalemia, hyponatremia, etc. Not all edema can be treated with diuretics, such as edema caused by albumin deficiency, which can be reduced by replenishing albumin, and diuretics are generally not needed. Patients with edema should go to the hospital in time, and the use of diuretic drugs should be under the guidance of professional doctors.
