I began to have indigestion in December of 2001. Went on Prevacid which seemed to help alot, especially with heartburn at night. I've always had loose stools, but about a month on the Prevacid I started to have real diarhhea. I have always believed I have IBS but this is different than anything I've ever had. I'm 45 and know I'm going thru menopause. Periods have gotten very irregular, plus my mother went thru it at 46. I'm wondering if this could be related to menopause. I've had an abdominal ultrasound and a vaginal ultrasound. Normal findings. I also must mention that I've been drinking alcohol a lot in the past couple of years, which has affected my digestion.
