Cryptogenic nephritis 40 years, if the patient has no obvious discomfort symptoms, usually no need to treat. If the condition is more serious and patients have symptoms such as hematuria and proteinuria, they need to actively look for the cause of aggravation of the condition, and can follow the doctor’s instructions to use general treatment, medication, surgery and other ways of treatment. 1. General treatment: During the period of illness, we should take care of ourselves, keep a regular routine, avoid overwork, avoid smoking and alcohol abuse, avoid using nephrotoxic drugs to reduce the damage to the kidneys. Patients should also regularly monitor the changes of urine routine, urine protein, renal function and blood pressure. 2. Medication: For patients with proteinuria accompanied by hematuria, or patients with predominantly simple proteinuria, they can take oral ACEI/ARB drugs as prescribed by the doctor, such as timosartan tablets, closartan potassium tablets, irbesartan tablets, captopril tablets, enalapril tablets and so on, and the blood pressure needs to be monitored regularly during the use of the medication. 3. Surgery: For recurrent chronic tonsillitis, closely related to asymptomatic hematuria and other episodes, tonsillectomy can be performed as prescribed by the doctor after the acute phase. If you have been suffering from cryptogenic nephritis for 40 years, it is recommended that you go to the hospital to determine whether you need treatment; if the condition is serious, it is recommended that you follow the doctor’s instructions for standardized treatment.
