I keep getting Diagnosed with IBS has to be more difference between IBS, UC and CD

New here with questions.
I have been mostly D for 20 + years, my vitamin absorption has gotten much worse. I keep getting diagnosed with IBS. It has to be much more then that. My newest symptom is constant thirst and dry mouth I have 1 child with type 1 diabetes so I used his meter to check my sugar and my glucose level was fine. Please see the following list of issues

Symptoms are 20 years of loose stools
15 years chronic anemia still battling last hemoglobin level was 6.8 threatened me with iron infusions
Nighttime Bathroom runs,
Insomnia,
Bad Smelly Gas
last 2 years severe bloating
1 yr severe indigestion
1 year really bad itchy rash scars to prove it
Pica Ice and salt,
Mucus in stool not so much at the moment use to see a small amount of blood with mucus not any longer.
Cannot gain weight even have weighed as little as 90lbs currently 110
Cannot eat dairy of any kind get bloated with diarrhea

I am 6 weeks Gluten free try the elimination diet. When I removed the wheat and Gluten My Indigestion totaly went away. Also removed Dairy and soy from my diet, Fiber sends me running to the bathroom every time. The Iron and Vitamin C also give me Digestive problems Vitamin C give me D and iron just upsets the whole thing. I am so sick of this crap I have not idea where to turn at this point I work a full time job and it makes it really hard on me. Anyone have any ideas?

I think your elimination diet will give you answers. Keep a food journal and listen to your gut, it will tell you.
Gluten and dairy are two of the most common problem foods but you may find others.
I don't take many supplements since they seemed to do more harm than good for me.
Protein and non-starchy veggies is a healthy diet plus nuts and a spoon of oil daily (olive oil, fish oil or coconut oil).

Diet control takes some time to work but glad you've gotten improvement so far.

I had a colonoscopy about 10 years ago they found nothing. 12 years ago I was first diagnosed with Iron deficiency Anemia Iron level of 7.4 I was sent to a GI doctor who Diagnosed me with IBS based on Ultra sound and exrays and physical and labs did not do a colonoscopy at that time. In 2005 I had a really bad Infection and went to the Dr they put me on Z pak and Lexapro I refuse to take Pexapro that stuff makes me ill. I have continued to suffer in silense until recently. last year I started getting the most bizzare rash it was bad I mean really bad. It has almost all gone away execpt for a few places since going off dairy and wheat and increasing my Iron. The name of the rash is Prurigo Nodularis I was sent for labs everything checked out good except my Iron and B-12 I pick my labs up on Friday where I will have more detail. I have not ever been tested for food allergy everytime I have ever suggested it the Dr looks at me like I have 10 heads. Grrrr But as I have stated above Ive noticed I absolutly cannot digest Dairy and wheat seems to be a problem as does soy as far as I can tell. I'm just confused by all this.

I'm so sick of D and feeling crappy all the time

Did they take biopsies at the colonoscopy? Usually the biopsies will show inactive UC or CD if it is present. It is possible to have all of the symptoms you experience and IBS. Have you visited the IBS board? Many have quite severe symptoms with IBS. Have you tried an antidepressant or antianxiety medication? I have heard they can help quite a bit for IBS.

If you feel better on a gluten free diet it could be that you are intolerant of gluten. It often takes a long time to heal the damage that gluten can do to your upper GI. I'd suggest getting an endoscopy done to take a biopsy of the upper GI tract for a celiac diagnosis, but you'd have to resume eating gluten again to get a trustworthy result.

about 80% of adults are lactose intolerant to some degree, so I wouldn't worry too much about the dairy issues if you can tolerate it while using supplementary lactase, like lactaid tablets with your dairy meals.
