My experience is that medics don't know very much about anything. Medical science is _so_ over-rated, they don't know anything like as much as their inflated reputation suggests (just look at the frantic learning process we've witnessed in the course of this pandemic).
I can relate.
My mom had some questionable blood numbers indicating potential prediabetes but the doc didn't order a HbA1C yet. Her most recent blood test in Nov 2021 registered a blood glucose of 105 and he messaged back saying they'll check it at the next appointment...in May 2022. She first went there in Aug 2021 for a few things, namely a persistent "bubbly" and red patch of skin on her right tibia area leg that's been there for a year or two.
There was also the usual "drug fixes"; I don't think he was pushy or anything. Statins and biphosphonates. If one agrees to the statins, then it would be a persistent, long-term period of intake of over 5 years.
Her hearing has been deteriorating, so I find myself wearing earmuffs or headphones when she's talking to me because I can hear her more than loud and clear.
Stumbling into Ford Brewer's channel certain provided some useful information regarding heart attacks, lifestyle prevention, etc. He used to head the preventative medicine unit at Hopkins.
Doesn't say much for your "experience" is my take-away from this post.
Definition of science:
"the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment."
Doctors are essentially practical scientists and thus DO NOT know everything obviously, however you are 100% mistaken in that they do have quite a bit of knowledge.
We have quite a ways to go before Dr McCoy's medical "Tricorders" but all kinds of stuff that was a quick death sentence when I was a kid is treatable or curable now.
While I do not agree with Dr. Michael Greger on his vegan tendencies and certain inaccuracies, his experience going through med school and the like indicates that the common doctor is not always someone who is sure to fix a person up healthy; the might have tunnel vision about simply fixing what shows up in the diagnostic. It's probably the most valuable information in his book How Not To Die.
