I have heard that IBS could be related to hormones, i was just wondering if anyone else knew anything about this. I am taking a birth control to regulate my periods, i have been taking it since january, and it hasn't regulated me at all. in june i was diagnosed with IBS, and i was just wondering if maybe the birth control is making my symtoms worse. The pain is getting so severe and so frequent that it's beginning to affect my life. The pains started coming every morning this week, and they used to only come at night. Also, the pain moved into my lower back today, and it was very severe. So, i'm thinking about not taking my birth control, and i think that my medicine, hyoscyamine, may be what is causing me to get such severe pain in the morning. I just started this medicine last wednesday, and on tuesday morning, i got sick, and i have been sick everymorning since then. If you have any advice or any information, please let me know. I am trying to call my doctor, but he never returns my calls, and it's hard to go see him since i am 2 hours away from him at college, but i do have an appoinment scheduled in 2 weeks. Thanks for helping me out, i really appreciate it.
