Ah penguin and Clarabelle - this is exactly my case.
I dont have conventional gerd - actually, wouldn't that have shown up on the endoscopy??? Maybe not.
What I have is constant discomfort in my stomach, but it moves around and brings intermittent acid. It was brought on by my stupidly taking a bigger dose of progesterone - which I instantly reduced.
I've had it on and off all year whilst trying to get on progesterone. As I up or down dose if seems to be a trigger. I'm on progesterone only therapy under a bhrt clinic - before anyone freaks about my dosing
So it's definitely hormonal. It is very tiresome Clarabelle. Trying to stabalise on hormones is bad enough without this hell thrown in along the way
I've had bouts of gastritis previously on the mini pill - they always responded to H2 blockers of ppi. But all the stuff this year won't respond, in fact, they make it worse.
Absolutely nothing to see in my stomach or oesophagus, whereas previously, the gastritis was seen.
I'm with you penguin, its diet or stop the hormones.
I'm trying the low histamine as it's possible gastric issues are a mast cell response and I do have a lot of allergies and high E, which I have, causes histamine. Tenuous links. But I'll try.
I've tried gluten free before - probably when I had the gastritis. Didn't seem to help.
