It's important (doctors would do well to understand) to give any change in medication/stopping medication or diet/lifestyle changes time to work. As we get older, our bodies often need more time to adjust, and while they are doing this, various readings go high and low while the body seeks homeostasis.
For a personal example, thanks to my dietary changes, as well as BG falling into the 'remission' range, my HDL and Triglycerides have dropped to a most satisfactory level, while my LDL has dropped too but not quite so well as Nursie requires. "It's only down .5" she said in a dismissive manner. I pointed out that if it had gone UP by .5 she'd be even more critical.
Each of us will make up our own minds about what we do and don't take by way of medication. Having read a lot of proper research, I'm quite happy for cholesterol readings to drop as my body requires, and - frankly - having read the most modern research, I'm not concerned about it at all. I remain obdurate about refusing to take statins. Knowledge is power!
