Diabetic nephropathy with facial swelling is generally due to too much protein in the urine and too little protein in the blood, causing hypoalbuminemia, which leads to edema. There are several methods to control diabetic nephropathy: First, blood sugar and blood pressure must be strictly controlled within a normal range. Blood pressure control should be even stricter for those with diabetic nephropathy, generally kept below 130/80. Second, in terms of diet, it is crucial to avoid or limit intake of bean-based foods and consume high-quality proteins instead. High-quality proteins include commonly known meats, eggs, and fish. Third, it is essential to limit or avoid the use of medications that can damage the kidneys. Fourth, if diabetic nephropathy causes general body edema, intermittent use of diuretic medications can help alleviate the swelling, along with nephroprotective medications. The final method for severe kidney disease involves early intervention with hemodialysis or peritoneal dialysis. (Please use medications under the guidance of a doctor)
