Chronic nephritis is generally more serious, due to its prolonged condition and slow progression of lesions, there may be different degrees of renal decompensation, and some patients will eventually develop into end-stage renal disease. In the early stage of chronic nephritis, symptoms such as hematuria, proteinuria, edema, fatigue, back and knee pain may appear, which will affect the quality of life of patients. Without treatment for a long period of time and with continuous progression of lesions, chronic renal failure may develop, and when combined with infections, high blood pressure and other conditions, the progression will be faster, which will shorten the life span of patients. Therefore, after diagnosed with chronic nephritis, treatment should be carried out as soon as possible, and during the treatment period, patients should follow the doctor’s instructions, use medication reasonably, and do not use medication indiscriminately.
