This is PRECISELY why I rarely if ever just defer to medical advice when given. One thing I’m not is dumb, and I can grasp just about anything other than the most complex parts of organic chemistry if you will just take a second to explain. Doctors never want to do so, they just want you to accept what they tell you as gospel. One time I said I’ll be back in a second and came back with a recent Pub Med article with a study refuting what the doc had advised. To his credit, he said he had not seen this and would have to reconsider his position. But that’s the rare response. Most of the time it’s just if you’re not going to accept my advice, get a different doc.
