The time to progression of renal insufficiency to uremia is related to the type of pathology, the severity of the disease and the treatment, and cannot be generalized. There are acute and chronic renal insufficiency, and the main symptoms are edema, hypertension and proteinuria. In case of acute renal insufficiency, most patients with mild symptoms and timely treatment can recover completely and will not develop uremia for life. In the case of chronic renal insufficiency, it will gradually progress to uremia, and the specific time varies from person to person, ranging from 1-10 years. Some patients with more serious conditions, such as chronic renal insufficiency caused by lupus nephropathy or diabetic nephropathy, nephropathy damage, etc., may progress to uremia in 1-2 years. If the primary disease can be effectively controlled, with Chinese medicine to protect the kidney function, it can prolong the time of development of renal insufficiency to uremia. Patients with renal insufficiency need to go to the nephrology department of regular hospitals in time to be examined by professional doctors to make a clear diagnosis and to develop a reasonable treatment plan.
