Hi
Whilst peri is a nightmare, i think i would fear the endoscopy more, what is Omerprazole is it a pill, or medicine for acid?? ive taken ant acid called Asilone in medcine form and it worked for me, does your tummy feel like it has a massive butterfly in it, and your heart beats fast, and you cant sleep?? but its the stomach that is worse in your case, if so, its a sign of too much adrenalin in your system, drink plenty of water without over doing it, messing your electrolytes up, take gentle exercise, to avoid fatigue becoming worse, and then producing more adrenaline, causing a vicious circle,
Because menopause affects our sugar level, eat little and often, eating a high protein low unrefined carb diet, avoidjng sugar as much as you can, you need to keep your sugars balanced, like your water, and exertion, to avoid highs and lows of everything, because when you eat refined sugar inparticular, its absorbed very quickly, into our system, and to bring the sugar level back up, the body then sends out masses of adrenalin and thats what can cause your acid probs, if this is what has been happening to you, that you notice acid stomach comes on after eating, but, then when you try to eat again your symptoms go, well they go because the adrenalin has brought the sugar level back up, and eating makes it level off so you feel better, but eating then creates more adrenalin, and thats where you get the vicious circle from, if this is you, then its as sugar problem you have, your not a diabetic its the menopause doing it, and its happening because your putting the wrong stuff and too much of it in to your system during a menopausal flare, so you need to eat little and often, protein based as protein is absorbed slower than carbs, to avoid the adrenalin rush
I think i would try a diet change to avoid the endoscopy first, what have you got to lose, if it doesnt work, go for the endoscopy, or, ask for a barium meal instead, not a nice drink to have for it, tip ask for a straw.......... but you dont have hose pipe rammed down your throat with that.
Lsten to your body and help it to balance things out, its trial and error, but if you can do learn this it will help you control your symptoms.
