If uremia is not treated, patients usually die within 1 year or even within 1 month. The length of time is related to whether the patient has complications, for example, in the case of uremic patients with severe metabolic acidosis, severe hyperkalemia or severe heart failure, gastrointestinal bleeding and other serious complications, the patient may die within 1 month in a short period of time. However, if the uremic patient does not have the above complications and his condition is relatively stable, even if the blood creatinine reaches about 700-800umol/L or even 1000umol/L, the patient may still be able to last for a few months without dying. So how long you can live may vary depending on each patient’s condition, but in the days when dialysis was not widely available, uremic patients generally did not survive for too long.
