I’ve been on diuretics for heart failure since before I was diagnosed with T2D, so I don’t know whether or not they make a difference (don’t have a choice, anyway). I do take a beta blocker for my heart which I have heard might cause diabetes - who knows? I was overweight anyway with a carb-heavy diet, so it didn’t come as any great surprise.
Maybe you could talk to your doctor about Forxiga (dapaglifozin)? That has a diuretic effect by causing you to pee out excess glucose, so it might help blood pressure? Also, if you eat a high carb diet, lowering your carbs might possibly help your blood pressure
