    Depending on how intolerant you are, I have had severe reactions from 10 minutes or even the next morning. I can sometimes tell I am in trouble after a few swallows!

    Hi iandavis, you need to remember that IBS can be upset by other things like stress, mine has gone mad the last few days but through stress. It's not very funny is it? IBS can alter over time and can sometimes be clear cut and sometimes (well more often than not) very confusing. You can't quite tell when you'd have symptoms, you have to work out either what triggers them, if you can or how to stop the triggers.

    This is very individual. Digestion is underway in about 20 mins, so could be anywhere from 20 min to 24hrs really.

    This differs with me.

    Can be 5 minutes after but sometimes it is a few hours after or even the next day. Very variable.

    For me, sometimes it's almost immediate, before I've even finished my portion of whatever the offending food is. Bloating usually happens very quickly for me. The gas will usually take an hour or more to start up. Around 2 hours after a meal I generally feel the urgent need to use the bathroom.
