Acute renal insufficiency can be cured in general, while chronic renal insufficiency cannot be cured in most cases. Renal insufficiency is divided into acute renal insufficiency and chronic renal insufficiency. Acute renal insufficiency is also called acute kidney injury, at this time, after active treatment, most of the patients’ renal function can be completely restored to normal, and a small portion of the renal function will be mildly damaged. Chronic renal insufficiency is also called chronic kidney disease, patients’ renal function often can’t be completely restored to normal, it will gradually decline, and eventually may even lead to uremia. But at this time, after active drug treatment, can greatly slow down the decline of renal function, delay the time to reach uremia. Patients with renal insufficiency need to pay attention to low-salt, high-quality and low-protein diet, and try to avoid the application of drugs that have damage to the kidneys, especially traditional Chinese medicine containing aristolochic acid, so as not to aggravate the damage to the kidneys. Patients with renal insufficiency are recommended to consult regular hospitals and receive standardized treatment under the guidance of physicians.
