Dialysis is a process where a machine does the job of filtering and purifying the blood. However, the kidney also performs other functions, like producing hormones to regulate blood pressure and maintain electrolyte balance. A dialysis machine cannot do this. Haemodialysis is a type of dialysis that uses an artificial kidney (hemodialyzer) to filter wastes from blood.
Also, the lifelong cost of dialysis can work out to be expensive. You will also have to go to a dialysis centre regularly to get this done. There are many cities where these centres are not available nearby. Also, dialysis makes your blood super-clean and nutrient depleted and this blood keeps getting more and more toxic until the next dialysis session.
A kidney transplant works out to be more economical than lifelong dialysis. Kidney transplant price in India is much lesser than the cost of dialysis. It also lets you have a normal life as it is natural. Not only this, the survival rate and life expectancy of transplant patients are much better compared to people on dialysis. For example, it was found that the life expectancy of a person in the age group of 40 live 7.3 years on dialysis, but 22 years after a transplant.
After a successful transplant, you can live a normal, healthy life and even indulge in physical activities like swimming, cycling, etc. However, a person on dialysis will not be able to lead a normal healthy life and may not be able to travel to places where there are no dialysis centres. Thus, kidney transplantation is the best treatment option for a person with end-stage kidney disease.
