What in beer causes it to repeat on me the whole next day?

I'm pretty sure I don't have a celiac condition because whole wheat stuff doesn't bother me. But if I have a beer or two, the next day I will be bloated, very gassy and in the bathroom multiple times throughout the morning/afternoon. Is there an ingredient that is a common allergen or something?

@EtOHRx - other alcohols will sometimes mess up my stool the next day. Make it loose, or might have to go a couple times. But its different will beer, more symptoms with the gas. There might be something with your questions about the flora in my intestines might I am taking probiotics right now. This symptoms seemed to be a little curved by them with less trips to the bathroom but still lots of gas.

@nipper: Bottled beer. I can usually drink wine with little to no problems.

None that I have heard of or think of.

Could be that the alcohol is killing healthy beneficial bacteria in your intestines. This in turn allows fermentative bacteria to dominate and through their metabolism produce gas.

Does this happen with other alcoholic beverages?
