Hi...I have never heard that GERD can cause HBP, but GERD can be the result of stress and anxiety.
So, if u r able to reduce ur BP, u may be able to reduce ur GERD issues.
If you are taking a PPI such as prilosec or the generic omeprazole, peopl ehave reported the high BP as a side effect. I took 40mg omeprazole for 3 weeks and it elevated my BP.
I have GERD and I have been on three different Acid Reflux (GERD) medications and all raised my blood pressure but Nexium. I have high blood pressure (hypertension) without GERD though.
I am not aware of any relation between the two sickness.
