Something else I would recommend is getting a food intolerance test done. It helped me learn what food are irritating my gut and after 3 years of avoiding them and healing my gut it's so much better even if I eat the foods that used to bother me. I did an online test through https://us.checkmybodyhealth.com/pages/sensitivity-test-uss?utm_term=check%20my%20body%20health&utm_campaign=USA+-+Brand+-+Feb+2020+(Aira)&utm_source=adwords&utm_medium=ppc&hsa_acc=3566716633&hsa_cam=9299574881&hsa_grp=92254188697&hsa_ad=708684113757&hsa_src=g&hsa_tgt=kwd-867827799072&hsa_kw=check%20my%20body%20health&hsa_mt=e&hsa_net=adwords&hsa_ver=3&gad_source=1&gclid=CjwKCAjwyfe4BhAWEiwAkIL8sM6dECFc8pG4jFa-G15g4i8wjgdSbMAtXzMTbkuGexTkUm8tUKYl8RoChjkQAvD_BwE
I have bad IBS, and it’s a struggle with my daughter. I’d get a food intolerance test and demand a colonoscopy. I’ve had IBS for years and was constantly getting rejected for colonoscopies until I over exaggerated my symptoms - but better safe than sorry! I also would keep electrolytes on hand for flare ups - most of my light headedness is lack of sodium and potassium because it’s all running out. It doesn’t fix the problem but it’s a good bandaid! I’m sorry you’re dealing with it, it’s so stressful!!
Is your issue more gastric or bowel? I did my best from my flare-ups when I ate as clean as I could (no fried foods, no gluten, no dairy) for gastric symptoms I take probiotics and prebiotics I take dyciclomine (prescription for stomach spasms) for bowel I try to get lots of fiber (sometimes I use fiber powder) and I drink aloe Vera juice to coat my bowel lining (check the sugar though lots of brands have insane added sugar that would upset my stomach). I hope you can find some relief from your symptoms because it's honestly a hellish experience to have IBS
