How long you can live with nephritis depends on the type of nephritis and whether it is treated in time. Some nephritis with good prognosis, such as acute nephritis, may not affect your life expectancy, while patients with acute nephritis who are more severe and not treated in time may only live for a few months, and patients with chronic nephritis who have more severe pathology and are not treated effectively may live for several years. Less severe nephritis, such as acute glomerulonephritis, can usually be cured with standardized treatment and generally does not affect life expectancy. In more severe cases, such as acute nephritis, kidney failure can develop rapidly if left untreated, and life expectancy can be as short as a few months in severe cases. Chronic nephritis is prolonged and the lesions are all slowly progressive and may eventually progress to chronic renal failure. If the type of pathology is mild, and active and effective treatment is given, the patient’s life expectancy will not be affected; if the type of pathology is more severe, without effective treatment, the disease may progress to the uremic stage in a few years, which will seriously affect the patient’s life expectancy, and he/she may only survive for a few years. As we can see, the survival cycle of nephritis has individualized differences, so those who are suspected of having nephritis are recommended to actively consult a doctor, and under the guidance of a professional doctor to define the type of nephritis and give targeted treatment, in order to control the development of the disease and prolong the life of the patient. Nephritis patients are recommended to consult regular hospitals and follow the doctor’s instructions for standardized treatment.
