Edema of the feet due to nephritis is the edema of the feet caused by the failure of water drainage, the main manifestation of which is a swollen feeling on the surface of the feet and a pit when pressed. Edema caused by nephritis is the opposite of edema caused by kidney disease. Edema caused by nephritis is caused by the inability to excrete water due to the decrease in the drainage capacity of the kidneys, and the excess water will be retained in the body and will penetrate outside the blood vessels, which causes edema. The main manifestation of the patient is the feeling of swelling on the surface of the foot, which looks very much like a steamed bun, the swelling is more obvious, a pit when pressed, and if the swelling is particularly obvious, the pit can take a long time to recover after pressing down. For the edema caused by nephritis, you need to apply diuretic drugs to treat it. The more moderate diuretics are hydrochlorothiazide, while the more potent diuretics are furosemide and torasemide, but these diuretics cannot be used for too long, which can easily cause hypokalemia.
