Nephritis can be divided into three types: acute nephritis, acute nephritis and chronic nephritis. For patients with acute nephritis, most of them have the tendency to heal themselves, and their conditions usually improve significantly or return to normal completely within 8 weeks. Therefore, for patients with acute nephritis, the treatment time is usually about 2 months. For patients with acute nephritis, the condition is more aggressive and requires continuous treatment even after the risky phase, and the course of treatment is usually longer, even for life. For patients with chronic nephritis, if hormonal or immunosuppressive therapy is enabled, the course of treatment is usually 6-9 months. For those with poor treatment and prolonged disease, renal function damage progresses slowly and some patients will eventually develop chronic renal failure. Therefore, the treatment of patients with chronic nephritis is mostly a long-term process, and patients must come to the hospital regularly to follow up and monitor their renal function, electrolytes, 24hUP quantification, and other related tests, and regular follow-up.
