Poor renal function may be due to a variety of reasons leading to renal impairment, which can be improved by daily life conditioning and medication according to the specific causes. 1. Daily life management: first of all, we should control the diet, generally low-salt, low-fat, high-protein diet, through diet to reduce the intake of sodium and fat, supplement protein and other nutrients. 2. Drug treatment: patients with poor renal function should strictly control blood pressure, and can use angiotensin converting enzyme inhibitors such as captopril, or beta-blockers such as metoprolol. In addition, some kidney-protecting medicines can be used, such as huangkui capsule and so on. Therefore, if you find that your kidney function is not good, you should go to regular hospitals in time and get treatment under the doctor’s guidance.
