I'm new here. I've likely been suffering from IBS for about 15 years, but recently went to a GI - who confirmed it - though he did not do a colonoscopy or endoscopy yet because my symptoms "aren't alarming".. and there's no family history of anything bad. He started me on probiotics (allign - super expensive!), citrucel (which I haven't started yet because my diarrhea has been so bad I'm too scared to take fiber), and hyoscyamine sulfate to take before meals if I think I need it. What got me to go to a GI ultimately was that while usually I'll have an "episode" and then be fine for a month or so - I've been basically getting diarrhea every 3-5 days. Is it "normal" for symptoms to worsen? I've changed my diet, and nothing seems to help. I go back to the GI in June to be tested for lactose intolerance, and I tested negative for celiac, and my thyroid is normal.Any suggestions? I've never had to miss work or fun for this - and suddenly it's becoming a major problem.I should add that I've also been getting heartburn - which is new. Is this related to the IBS?Thanks!
