Chronic nephritis is generally incurable at present. Chronic nephritis is a kind of chronic disease that exists for a long time and will deteriorate repeatedly. Its treatment mainly focuses on controlling blood pressure, restricting protein intake and protecting renal function, and it should follow the doctor’s instructions and carry out long-term drug maintenance treatment. 1. Control blood pressure: patients with chronic nephritis are usually accompanied by renal hypertension, hypertension can easily lead to glomerular hyperperfusion, high filtration, aggravate glomerulosclerosis, so it is necessary to control the blood pressure, generally can follow the doctor’s instructions for oral captopril, perindopril, valsartan drugs to lower blood pressure, and at the same time, this kind of drugs also has the function of lowering the urinary protein, to slow down the progress of renal disease. 2. Limit protein intake: Limit protein intake can play a role in reducing glomerular hyperperfusion, high filtration, high pressure, and delay glomerulosclerosis, limit protein in daily life, but not an absolute restriction, can be moderate consumption of high-quality protein foods, such as milk, eggs, meat, etc., the daily intake of protein 0.6~1.0g/(kg-d), while controlling the dietary phosphorus intake. Intake of phosphorus in the diet should also be controlled. 3. Protect kidney function: daily rest, ensure enough sleep, avoid overwork, avoid infection and other diseases, avoid taking nephrotoxic drugs, such as aminoglycoside antibiotics (gentamicin), cephalosporin antibiotics (cefazolin), and follow the doctor’s instructions when you need to take drugs. Chronic nephritis patients should actively regular hospitals, under the guidance of the doctor for standardized drug treatment, do not be negligent, so as not to delay the condition.
