How long can you live with dialysis three times a week

As we all know, dialysis is only necessary for many more serious diseases. Dialysis causes considerable harm to the patient's body. Many friends will ask: How long can you live if you undergo dialysis three times a week? In fact, this mainly depends on the patient's physical condition. If the patient has good physical fitness and good home care, he or she can actually live a long time.

Many people know that dialysis is a treatment method that needs to be adopted when kidney disease patients' condition develops to a certain stage and the kidneys can no longer perform their functions. If dialysis is needed, it means that the kidney function is very poor and has basically lost its function. So is it serious to undergo dialysis three times a week?

Is it serious to have dialysis three times a week?

It is not possible to judge whether the condition is serious just by looking at the number of dialysis sessions. The number of dialysis sessions can only reflect the amount of various chemical elements circulating in the patient's blood that should be filtered out of the body by the kidneys and the patient's kidney function.

In clinical practice, there are people who have been undergoing dialysis three times a week for 10 years and are still alive and well, while those whose disease is not well controlled may die in three or four months. Sometimes, a person's survival is mainly determined by his or her ability to fight the disease, rather than the condition of the disease. It mainly depends on personal control, including diet, exercising the nervous system and so on. Three times a week just means that this person's kidneys basically have no filtering function, which is basically in the middle or late stage.

If kidney transplantation is not considered, patients should pay more attention to whether other organs in the body are functioning normally, especially the nervous system, rather than the kidneys.

What is dialysis?

Dialysis, clinically, means the removal of some waste products from the blood through a semi-permeable membrane. Hemodialysis is one of the safer, easier and more widely used methods of blood purification. Dialysis refers to the movement of solutes from a high concentration solution to a low concentration solution through a semipermeable membrane.

Hemodialysis involves the movement of solutes and water, that is, blood and dialysate exchange substances in the dialyzer through semipermeable membrane contact and concentration gradient, so that metabolic waste and excess electrolytes in the blood move to the dialysate, and calcium ions, alkali groups, etc. in the dialysate move into the blood. If a mixture of albumin and urea is placed in a dialyzer and the outside of the tube is soaked in water, the urea in the dialyzer tube will move through the pores of the artificial kidney membrane to the water outside the tube. Albumin molecules are larger and cannot pass through the membrane pores.

The phenomenon of material movement in which small molecules can pass through the semipermeable membrane but large molecules cannot is called diffusion. The basic principle of hemodialysis is to use diffusion phenomenon to separate and purify blood to achieve the purpose of purification.

From the introduction in this article, we can know that if dialysis is performed three times a week, the kidneys basically lose their basic functions, which is already a relatively serious situation. If you are a person who needs dialysis, you'd better know that your condition is already quite serious and you need to actively cooperate with the doctor to do dialysis.
