So I tried some low fodmap stuff for a while... Mine is now fairly under control with a mixture of things:
- Contraceptive pill - my IBS gets 10x worse when I have the week off.
- Semi- low FODMAP diet - I used it as a bit of a trial and error thing. I have to avoid too much fibre, but the absolute killer for my is Galacto-oligosaccharides. All beans (including soy products like soy mince), chickpeas and lentils. I can cope with things like green beans where you're mainly eating the pod. Peas aren't great but I can eat a few.
I also can't drink beer at all, other alcohol is okay but even a pint makes me pretty unwell - I can occasionally get away with half one but it's generally not worth the consequences.
That's been combined with moving to a lower stress job, which really made a difference in getting it under control, but interestingly now it is under control even when my job is incredibly stressful I am still a lot well-er than I was.
I also avoid chilli/"hot" spicy foods.
I think it's sort of like this: the food things above make me ill whether I'm stressed or not, but if I am incredibly stressed pretty much any food could also make me ill.
For context I lost 2.5 stone in 8 weeks at the peak of my IBS and was on 20+ tablets a day to try and control it without success. It was life ruining - I was at uni for the worst of it and gave up alcohol totally. I used to sit in lectures just crying because of the amount of pain I was in. I was told it might never get any better and could hardly bear the thought I might have to live my life like that.
Now I rarely take any medication, still have some acid indigestion issues and digestive unhappiness but am able to go out for dinner, work normally etc and live a normal life.
