I have had IBS for 10 years now. I was living with it until, severe heartburn started about 3 years ago. Both together are not fun. The D was not bad or often. The heartburn also was not bad unless I ate a big meal late at night. Nothing helped the heartburn. About 3 years ago my IBS flared up and never went away. I finally decided to go to the GI. I had all the tests and they found nothing except in my blood work they saw some gall bladder problems. The doctor asked if I had what felt like heartburn alot. I said yes, but that's not why I came to you, I wanted the D taken care of. The ultrasound showed gall stones. I had the operation 2 years ago, and I rarely have heartburn any more, but the IBS is worse. Nobody warned me of this. Now I feel the IBS was GB related, and maybe the GB was bad all this time. Instead of fixing the GB, I don't have one anymore and my system is Sh*t out of luck. (pardon the pun). This is my first entry on the BB, but have been reading it for months. Calcium pills helped for a while, but not always, and it seems they don't do anything anymore. I am writing this, because your problem sounded like mine. Your heartburn might be an inflamed gall bladder. I am still searching for what helps me.Good luckEric
