Elderly people with bloated stomach and swollen feet may be due to malnutrition, cirrhosis, renal failure, heart failure, etc. They need to be treated with drugs such as furosemide or surgery for the cause. 1. Malnutrition: as the elderly age, the body’s metabolism is low, nutritional intake and energy utilization is reduced, resulting in the symptoms. This situation needs to ensure that the elderly protein and other nutritional intake, eat more nutritious and easy to digest meat, eggs and dairy food. 2. Cirrhosis: After cirrhosis, liver cells and tissues die off, and the synthesis of albumin by the liver is impaired, resulting in hypoproteinemia and a decrease in plasma colloid osmolality, which leads to the development of this symptom. It can be treated with drugs such as entecavir, spironolactone, reduced glutathione, or surgery such as portosystemic shunt or liver transplantation. 3. Renal failure: When the long-term chronic kidney disease of the elderly progresses to the stage of renal failure, the glomerular filtration rate decreases significantly, resulting in sodium and water retention, so the symptoms appear. It can be treated by hemodialysis, peritoneal dialysis or kidney transplantation. 4. Heart failure: cardiac dysfunction leads to circulatory stasis, increased capillary venous pressure, and increased fluid exudation from the interstitial space of tissues, so this symptom appears. Furosemide, spironolactone, sodium nitroprusside, digoxin and other drugs can be applied. Pay attention to the standardization of diagnosis and treatment under the guidance of physicians.
