I'd taken Proton Pump Inhibitors (omeprazole) and they did help with the acid indigestion etal. However, I noticed more often than not that they seemed to cause heart palpitations. Strange but true. I stopped them and never had anymore. I've read that the palps came from irritation of the vagus nerve caused by the PPI and lack of acid digesting. As we likely know, the vagus nerve can affect organs from your head to your intestines when it gets irritated. I've since investigated natural 'helpers' for stomach related issues and of course, really worked on my diet as well.
