How to perform dialysis treatment for uremia?

Uremia is a kidney disease in the human body. If uremia is not treated in time, it may be life-threatening. Uremia will affect the body's excretion of waste, affect the body's normal life, and greatly affect physical health. There are many ways to treat uremia. Depending on the different symptoms, dialysis is the best treatment method.

How does dialysis work?

Dialysis is the process by which solutes pass through a semipermeable membrane from one side to the other. Any natural (such as the peritoneum) or artificial semipermeable membrane, as long as the membrane contains pores that allow solutes of a certain size to pass through, then those solutes can move from one side of the membrane to the other side of the membrane by diffusion and convection.

Hemodialysis utilizes the principle of a semipermeable membrane to introduce the patient's blood and dialysate into the dialyzer at the same time. The blood and dialysate flow in opposite directions on both sides of the dialyzer membrane. With the help of the solubility gradient, osmotic gradient and water pressure gradient on both sides of the semipermeable membrane, toxins are removed through diffusion, convection and adsorption. Excess water in the body is removed through ultrafiltration and osmosis. At the same time, necessary substances are supplemented to correct electrolyte and acid-base imbalances.

What does dialysis do to the kidneys?

Dialysis is the process of replacing the work of the kidneys. When a patient enters the uremia stage, his or her kidneys should be damaged by more than 90%. If you keep delaying and not taking alternative treatment, the toxins will remain in the body. The "poisons" in the human body include metabolites, drugs, and exogenous poisons. As long as their atomic weight or molecular weight is appropriate, they can be removed from the body through dialysis. The basic principles are diffusion and convection.

What are the dangers of long-term dialysis?

Long-term dialysis for kidney disease will lead to dependence. Dialysis is only an auxiliary tool for treating kidneys. It can only relieve the pain as quickly as possible but cannot eliminate the root cause. Long-term dialysis will make the human body dependent, and it will have side effects on the body over time. Dialysis for kidney disease can save lives, but it cannot cure the disease. Dialysis can detoxify toxins from the body promptly and quickly, but the complications after dialysis are many and serious, and may even be life-threatening over time.

Precautions

After dialysis, the kidneys will slowly stop functioning and completely lose their function over time, at which point there will be no way to treat or repair them.

Dialysis for kidney disease will gradually damage the kidneys. If patients rely solely on dialysis for a long time, the only function of the kidneys will atrophy and become useless due to long-term disuse, and they will no longer be able to reproduce after dialysis.
