Some of the most useful therapies are natural substances like insulin and thyroid hormone.You do realize that modern medicine is actually harnessed natural processes, right? As in "nature refined," for a more accurate descriptive. You are actually denying that nature works when you deny modern medicine. But your failure to comprehend that shows you know nothing about medicine, or how it works. You know less about science than even a layperson, and less about reality than those with god delusions.
There are medical conditions where much less progress has been made, and the available therapies relatively are much less effect while being just as toxic - approaching futile therapy. Patients with such problems will always have bad outcomes and unfortunate stories to tell. No physician can stop it, either, since not surprisingly, such patients change doctors regularly. Recommending that somebody like that stay home rather than press for futile therapy is futile advice. I know. You just lose a patient.
Also, you won't hear as much from the patients with problems that respond well to existing therapies. You have to keep that reporting bias in mind when wading through the message boards of people still looking for answers. They all have horror stories.
The criticisms of medicine are largely valid. It is a treadmill of poisons, runaround, and conflicting advice.
Nevertheless, modern medicine helps many people. The population changed in my time. I showed you the rheumatoid nightmares that we've conquered in that time, and which are now rare. There are others. When I started, congestive heart failure was common. Tons of people had pedal edema and took potent loop diuretics like Lasix. That was unusual by the time I signed out.
Anyway, it's a two edged sword. You need to be an informed and wary consumer. But there is benefit there, too.
