Suffered GERD and given Omeprazole - side effects of which were nausea, headache, confusion, dizziness. It cant be a coincidence that these side effects are also the symptoms of too LOW stomach acid and are therefore making the situation worse. it is difficult if not impossible to get a GP to agree that low stomach acid can cause GERD and to prescribe HCL (HYDROCHLORIC acid) tablets to redress the balance. Whilst it is possible to self medicate it is a bit worrying and I wonder why the pharmacists have not come up with a solution recognised by GPs. Does anyone have a GP who agrees with me and if so, what do they prescibe? I have asked if there are any tests I can have to establish if it is high or low but told there are none.
