I was diagnosed with IBS about 10 years ago as I was alternating constipation and diarrhoea, and have managed it since with a high fibre diet. Over the years I've cut out white bread, white rice, and white pasta, until I reintroduced during pregnancy in 2013 and was fine. I seemed fine during pregnancy and while breastfeeding.
During this time I've found things that give me a funny reaction - pizza, samosas from my local Asian supermarket, malt loaf, shop brought naan bread, things like that. Very wheats beer is also a problem. I'd narrowed it down to probably being some sort of preservative used in things that are part baked or produced cheaply, so I just avoid those things and have been ok.
The reaction is achey joints, feeling fluey (including feverish shakes), and then constipation/brick in stomach feeling for a couple of days. Ginger tea and ibuprofen seems to help. It doesn't sound like much but I have to retire to bed when it takes hold - the achey joints are like waves of a feeling that makes me feel almost seasick.
DD3 is 10 weeks, and I've had two episodes of this in the last fortnight. No idea what the trigger could be, or why exclusive breastfeeding isn't protecting me this time.
I'm absolutely fine with brown bread, homemade or shop/Cafe bought cakes and biscuits (except fondant fancies - I get a funny crash after eating those, presumably from the sugars and colouring?), and since DD2 was born have kept eating white rice, white pasta and noodles with no issue.
I'm worried that if I see the GP they'll just tell me to avoid processed food (I have 3 kids under 5 and a teenager - I need to be realistic!). I've heard that online allergy testing is inaccurate and costly.
Any thoughts? I'd be very grateful for any ideas or insight. After reading this board quickly today I've read about FODMAP but I eat lots of those things regularly and have no issue.
Thanks for getting this far!
