| antibiotics and water retention
I'm currently taking rifaximin for an overgrowth of bacteria in my small intestine. I haven't actually been diagnosed with IBS, but it's looking more and more like that's what I have.
Anyway, I am 1 week into a 10-day AB course and I have experienced severe bloating several times. I have also gained 6 pounds in one week, which is very abnormal for me. I know that ABs can sometimes cause bloat, but I have never heard of water retention and am wondering if that is where my weight gain is coming from. Hopefully this will subside when the antibiotics stop because it's very uncomfortable and all my clothes are very tight right now! Oh, I am also taking acidophilus, which seems to be helping a little bit...
