Dad and mom both have / had HBP. Dad uses Diovan, as someone else mentioned He has not side effects. And yes it often goes along with hypothyroid, which may well be part of the weight issue.

My brother (only sib) also has HBP, but it not taking any meds for it.

I have low blood pressure, go figure. Not low enough to need meds for it, but slightly below normal ALL the time.
