The choice of diuretic methods for reducing edema usually depends on the cause of edema. Common causes of edema in the body include cardiogenic edema and nephrogenic edema. The main methods of diuretic edema are general treatment and etiologic treatment. 1. General treatment: Appropriate bed rest is conducive to the improvement of organ blood supply, reducing the load, and facilitating the recovery of patients with edema caused by organ dysfunction. Generally, edema patients will have different degrees of sodium retention, so they should be given a low-salt diet to reduce the sodium content. 2. Etiological treatment: according to the cause of edema, such as cardiogenic edema generally includes vasodilatation, diuretic therapy such as furosemide, spironolactone and cardiac treatment. Nephrogenic edema can mainly apply diuretics, hydrochlorothiazide, furosemide and so on. There are many causes of edema, and the methods applied for different causes are different, and the specific medication needs to be used under the guidance of a doctor. Therefore, if you have edema, you should go to the hospital in time to get a clear cause, actively treat it, and avoid self-medication.
