Your post details a very sad situation, @freecompliments, for your grandmother. Any of us who are not doctors face a lot of questions about the validity of many of these medication recommendations. The whole topic of cholesterol and what, if anything, to do about it, being one common example.
Your grandmother is fortunate that you are in her life. And can intercede on her behalf. Hopefully, she will follow your advice and experience some confirmation of having made the right choice.
What is your perception, from your professional history, of the "Make America Healthy Again" slogan and what we can read about what RFK, Jr. and his allies have to say about their plans for taking on that enormous challenge. That all is not well seems to be self evident. If true, what to do about it?
