Why do some doctors ignore the medical evidence, as well as our legitimate requests as a patient?

That is really terrible behavior. Sometimes I wonder whether doctors suffer from cognitive defects, making decisions and when they are wrong, ignoring all evidence to the contrary. Most recently, I’ve struggled with seemingly overwhelming evidence that my doctor is in fact not even working for me (https://forum.tudiabetes.org/topics/can-i-trust-my-dr-he-feeds-at).

I hope you heal quickly.
