Clinically, according to the different causes of water and sodium retention in the body, different treatment methods can be taken: i. Patients with renal insufficiency, too much water in the body can not be excreted, at this time you can use drugs such as renal health and prostaglandin to restore the function of the kidneys. If necessary, dialysis treatment can be taken, both to remove water and sodium from the body and to relieve the pressure on the kidneys. Second, reduce the intake of water and sodium, mostly seen in patients with liver and kidney insufficiency. At this time, it is more difficult for patients to excrete water and sodium in the body through drugs, so the intake of water and sodium can be reduced to avoid the performance of water and sodium retention. Third, patients with cirrhotic decompensation often have inactivation of estrogen, when the hormone level of aldosterone in the body is significantly increased, which can cause a large amount of water and sodium retention. At the same time, due to the weakened synthesis of albumin, a large amount of water in the blood vessels seeps into the abdominal cavity, causing a large amount of peritoneal fluid. Therefore, it is necessary to reduce water and sodium retention by supplementing albumin, increasing colloid osmotic pressure, and enhancing furosemide diuresis.
