Why can't they recover so they don't need an organ transplant? Do you think, maybe, that they were subject to a good sales pitch about their condition from the medical, and really never needed the transplant in the first place?
There are many things that are oversold and in US medicine for profit but transplants don't typically fall into that category. Its very hard to get a transplant regardless of need due to a shortage of healthy donor organs.
Your correct that many transplant patients could have healed themselves naturally and avoided a transplant but the window of opportunity for such healing is usually long gone by the time a transplant is ever discussed. The kidneys and liver have a limit to their regenerative capacity. They can heal to a point but past that they won't recover.
The two most common causes of Kidney failure are diabetes type II and hypertension both of these can often be
treated by diet, exercise, and weight loss. The most common causes of liver failure are alcohol abuse and hepatitis infection also both preventable.
In health as in so many other areas of life people are often their own worst enemies.
