High blood pressure may damage the kidneys. When the patient’s blood pressure is always higher than normal, it may increase the pressure of the glomeruli, thus causing kidney damage. When the patient is in the state of high blood pressure for a long time, it may cause damage to several parts of the glomeruli and tubules, triggering proteinuria, hematuria, etc., and in serious cases, it may also cause nephrotic syndrome, renal failure and other diseases. Symptoms that may appear in patients after kidney injury caused by hypertension include edema, especially in the lower limbs, face and other parts of the body, which is mainly due to the body’s sodium and water retention and other reasons for the symptoms, which need to be treated in time. Patients with hypertension can be treated with drugs such as amlodipine, Benadryl tablets and enalapril. Hypertensive patients should follow the doctor’s instructions to use drugs in daily life, eat a light diet, avoid eating greasy and stimulating food, consult a doctor in time when abnormalities occur, monitor blood pressure and follow the doctor’s instructions for treatment.
