I wont go into all the things that go into a person developing type 2 diabetes but I do agree there are better options for hypertension than beta blockers.My diabetes & three other members of a large family all got diabetes type 2 after we had been dished out the same Beta blocker Atenolol when the internet first arrived I checked it out & it stated then - warning the tablet can damage the pancreas & cause type 2 diabetes ... the only three people in my family like me were prescribed this tablet = we ended up type 2 diabetics - a cheap & nasty cheap drug - My GP changed me to far better Blood pressure tablets as he was fuming as my BP was only slightly high back then ....
It was in the era that snooker players were using them to enhance their performance as it slows the heart down etc - funny enough at that time I played in a snooker league after being on that tablet never lost many games..... my teammates were asking what tablet I was on
Please be careful to avoid Beta blockers if your BP is only slightly elevated -as IMO this is not a coincidence the only 3 people in my family end up with type 2 Diabetes, which is an awful illness to live with .....
That said there are beta blockers that are known to decrease the chance of a person with certain types of heart failure from dying. There are similar benefits for people after they have had a heart attack.
All medications have risks and benefits. That should always be part of the discussion with your physician.
Now back to pancakes...always in moderation.
