IgA nephropathy has many clinical manifestations and pathological types, and the treatment of IgA nephropathy is selected based on different clinical manifestations and pathological types. Usually, for patients with IgA nephropathy who only show microscopic hematuria, drug treatment is not necessary. They only need to regularly monitor routine urine tests, kidney function, and blood pressure changes in daily life, and must avoid using medications that are toxic to the kidneys. If the patient presents with gross hematuria related to tonsillar infection, tonsillectomy is recommended. If an IgA nephropathy patient has increased urinary protein, and the 24-hour urinary protein quantification exceeds 1g, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers can be used. Of course, for patients with significant proteinuria, steroids or immunosuppressants may also be used. In addition, IgA nephropathy patients can also be treated with traditional Chinese medicine. (Medication use should be under the guidance of a professional doctor.)
