Clinically, there is no fastest way to eliminate abdominal fluid. Abdominal fluid can be eliminated by puncture drainage, protein supplementation, taking diuretics, and clarifying the cause of the disease and treating the original disease. 1. Puncture and drainage: For abdominal fluid accumulation caused by cirrhosis and other liver diseases, abdominal puncture and drainage can be carried out under the guidance of color ultrasound, so as to discharge the excessive fluid and reduce the intra-abdominal pressure. 2. Supplementary protein: For abdominal fluid retention caused by hypoproteinemia, first of all, intravenous drip of albumin is needed, and at the same time, adjust the diet. Eat more fish, shrimp, milk and other protein-rich foods to correct hypoproteinemia and reduce the amount of fluid in the abdominal cavity. 3. Taking diuretics: For abdominal fluid accumulation caused by heart failure, you can take some diuretic drugs, such as tolvaptan, spironolactone and other drugs, to improve the function of the heart, so as to relieve the symptoms of abdominal fluid accumulation. 4. The cause of the disease should be clarified, and the original disease should be actively treated according to the cause of the disease, so that the clinical symptoms can be completely improved and the recurrence of hydroperitoneum can be avoided. It is recommended that patients identify the cause of hydrocele in time, follow the advice of professional doctors, choose the appropriate treatment plan, and follow the doctor’s instructions for the use of drugs to avoid adverse consequences.
