For patients with IgA nephropathy, the diet requires low salt, low fat, high quality and low protein principles, the daily protein intake is to eat five grams of protein per kilogram of body weight. For the treatment of IgA nephropathy, mainly use ACEI or ARB drugs, like Irbesartan and Benazepril, and pay attention to regular follow-up checkups at the hospital during the medication period to detect changes in the condition. If the 24-hour urine protein quantification still exceeds one gram after three months of drug treatment, patients need to add hormone therapy. In general, we should pay attention to not staying up late, overworking, not smoking, drinking, binge drinking, overeating and trying to prevent cold and flu to avoid aggravation of the disease.
