You do not mention your diet? What do you eat? Have you tried changing diet? I suspect you eat alot of carbohydrates and that might be you problem or one of them. At least if I was you I'd try low-carb diet at first and possible anti-fungal diet to at least rule out dietary problems.
Hi, welcome to our forum where we hope we can give you the help and support you need, but please bear in mind we are not doctors or nurses, just ordinary people who have Crohn's disease and can only give you the benefit of our own experience.
Your symptoms certainly need more investigation than blood tests, which cannot diagnose Crohn's, only point to an inflammatory condition in the GI tract. Of course, the symptoms could be the result of parasites, ibs, celiac disease, ulcerative colitis etc.
I believe you need referring to a gastroenterologist - a GP does not have sufficient expertise nor is able to do invasive testing to evaluate your current condition. Crohn's is definitively diagnosed by colonoscopy of the large intestine and/or endoscopy of the small intestine, with biopsies taken and sent to a pathologist for evaluation.
Take care,
