Well to me most doctors will be wrong because they simply want you to return so they can earn more of that money you have, not every doctor is out to get your money though, and so I don't use doctors no more. I use natural remedies for everything, and it all stems to how your Blood flow is being affected pretty much. Especially when it comes to poor nutritional habits, like eating fast foods, processed foods, and drinking harmful acidic drinks like soda, coffee, beer, liquor, and other drug related substances.
Your blood is highly important, and needs to be hydrated, so that disease cannot form with all the bacteria, and other toxins we intake daily, breath in or smoke up for those who are smokers. Research on the harmful effects that an imbalanced blood PH causes, I just found out recently and was literally blown away.
The doctors will benefit no matter what, because people are stubborn, and do harmful things to themselves knowingly & unknowingly.
This is the other reason why the accuracy of their diagnosis will be off, because they themselves have been leading bad lives mostly beginning with what they eat themselves, probably leading a false practice as well. Ever seen an over weight doctor, cause there are plenty, and weight isn't the only issue, the true health enemies hide inside the blood stream for the small and average sized person.
