How long a 65-year-old person can continue dialysis treatment needs to be analyzed with the severity of the disease, the presence of other complications, their own situation and other aspects, and cannot be generalized. Dialysis treatment is mostly used for patients with kidney failure, drug poisoning, etc. If the patient has lost most of the kidney function and is also accompanied by other high-risk diseases, such as coronary heart disease, diabetes mellitus, hypertension, etc., the duration of continuous dialysis treatment may be relatively shorter, or even the body can not withstand dialysis treatment. If the patient is poisoned by certain drugs and needs dialysis treatment, and the patient does not have serious acute or chronic diseases, his condition may gradually improve after a certain number of dialysis treatments, but the specific duration of continuous treatment needs to be judged in combination with all the indicators of the physical examination, and it is usually not possible to specify the specific duration of the treatment. If the patient needs dialysis treatment, it is recommended to go to a regular hospital in time and choose a suitable treatment plan under the guidance of the doctor.
