The length of time a woman needs to be hospitalized for acute nephritis depends on the severity of the condition, treatment and individual patient factors, and should be analyzed on a case-by-case basis. Acute nephritis in women is mainly caused by streptococcal infection, mostly with carnal hematuria as the first symptom, in the acute phase to anti-infection treatment. If the patient can be detected early and the symptoms are mild, Chinese medicine is particularly effective, usually hospitalized for 2-4 weeks, and regular review can be done after discharge. If the patient is sicker and has complex symptoms, such as edema and high blood pressure in addition to hematuria and proteinuria, hospitalization is usually required for about 3 months. Very few patients will develop acute renal failure, and conservative treatment is not effective, so they need temporary hemodialysis treatment, and the specific length of hospitalization varies from person to person. During the hospitalization period, patients are advised to take rest, avoid exertion, keep warm and prevent colds. The diet should be based on vitamin-based food and protein-based food intake should be controlled.
