I went to the doc and they found colitis, gasritis and vaginal bacteria and was put on flagyl. No yeast. Was also put on prevacid. Any advice on these meds. I already have bowel problems and want to keep them going. flagyl is suppose to constipated. I do take priobiotica once a day is that enough? I was having lower abdomen pain and diarrehea. Also found vagina atrophy and I can not take estrogen. I am in menopause but feel fine. Wants me to take estrogen but can not cause of side effects. She suggested estrogen vaginal creams. But never had an actual estrogen test. Is it lack of estrogen that causes that stuff only?
