Long-term hypertension can lead to abnormal kidney structure and function, also known as hypertensive nephropathy. Once hypertensive nephropathy is diagnosed, comprehensive treatment measures are often adopted, including both pharmacological and non-pharmacological treatments. In terms of non-pharmacological treatment, patients should maintain a low-salt diet in their daily life, focusing on a light diet, with a daily salt intake of about 4 grams. Regarding pharmacological treatment, the main goal is to control the patient's blood pressure and reduce urinary protein. Medications that can be used include angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists. Any of these medications can be chosen and used long-term to control blood pressure, protect kidney function, and reduce urinary protein. (Medications should be used under the guidance of a physician, and self-medication should be avoided.)
