Hi Jasmine_2015. I have suffered with IBS for years now and have found that HRT has definitely aggravated it. In fact, it's this that's made me give up on a lot of preparations I've tried because although they have dealt with meno symptoms, they have caused awful gastric side effects. The last time I saw my GP he suggested I try a low dose AD, Amitriptyline, to try to calm things down. I took these for 2 weeks but stopped because they were we're making me feel too zonked out !
I have some positive news though. I've been using Estradot patches, alongside a separate progesterone, for nearly 2 months now and although I did have some stomach issues to start with, they settled down after about 5 weeks and, touch wood, the stomach pain and discomfort are much better. I know we're all different but perhaps something for you to consider.
Wishing you well.
