I have IBS mainly IBS D . I have had it for around 50 years so it is well established and I know most of my triggers etc.
I have read that having to get up during the night to go to the loo is not a symptom of IBS..
I have noticed that quite often , if I have gas and a very uncomfortable gut after an evening meal but don't actually manage to have a BM , I sometimes wake up about 3am and have to go to loo. Usually one powerful emptying, ( sorry but cannot think of a nice description), often going from solid to liquid. Pain goes away and I get back to sleep and all is okay again. All this could be a result of a trigger that is new or one that I have not discovered as yet. Last night it occurred, fine this morning and it might have been alcohol that triggered it . We had a social evening where I had a couple of Vodka & diet cokes ,plus two glasses of wine with my meal. The food was a pasta dish that I would not normally have.
Anyway triggers are not my point, I just wanted to know if others have symptoms of really sore pains with gas and result in having to get up during the night to " get rid". As I said I have had IBS, often mild symptoms compared to many ,but fairly constant throughout the last 50 years. I have had spells of this night time needing just occasionally and I wondered if this was a problem with others. I would add that when it occurs I seem to know in advance that it is going to happen because of the feelings of discomfort in my tummy when I go to bed.
