As a physician, I can give further insight. The blood pressure medication the commenter is referring to is almost certainly a beta blocker. The effect on blood sugar levels is generally modest [1]. (It is rare to advise someone with diabetes to stop taking beta blockers, as opposed to say emphysema, where it is common)

They can be used for isolated, treatment of high blood pressure, but they are also used for dual treatment of blood pressure and various heart issues (heart failure, stable angina, arrhythmias). If you have heart failure, beta blockers can reduce your relative annual mortality risk by about 25%.

I would not trust an LLM to weigh the pros and cons appropriately knowing their syncophantic tendencies. I suspect they are going to be biased toward agreeing with whatever concerns the user initially expresses to them.
