Why on earth would anyone go without estrogen instead of simply taking a PPi?
This is stepping over pounds to pick up pennies.
One of the potential "risks" of PPIs the daily mail screeches about is osteoporosis (no evidence of causation, PPIs are likely just a proxy for multimorbidity, polypharmacy and in some cases an unhealthy lifestyle)
I would personally be far more afraid of untreated menopause than my omeprazole, which I have taken for 20 years.
Someone said they were taking a quarter of their estradiol patch, which on the NHS is statistically unlikely to be a 100mcg patch to begin with.
This has about the same level of estradiol as a first class stamp, and any reflux on this is unlikely to be related - or may even have been triggered by a reduction in dose.
