Intestine (Definition)

The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet).

Had colonoscopy/endoscopy this year both clear Except for high lymphocyte count in small intestine-had colon cleanse 2day afterward had bloody mucus ?

Had colonoscopy/endoscopy this year both clear Except for high lymphocyte count in small intestine-had colon cleanse 2day afterward had bloody mucus ?

Why did you cleanse?: Your database suggests enteritis--an inflammatory condition of the small intestine (like Crohn's disease or infection, among others). Your bloody effluent after cleansing raises concern for ongoing/undertreated inflammation. Please don't cleanse again, but instead start appropriate medication for your condition--call your doctor today. ...Read more

Colonoscopy found tiny ulcers in my small intestine doc questioning if Crohn's can this be if after iron infusion i now have normal CBC and iron level?

Colonoscopy found tiny ulcers in my small intestine doc questioning if Crohn's can this be if after iron infusion i now have normal CBC and iron level?

Small or large?: Doesn't really make a lot of difference, but i suspect colonoscopy found ulcers in large intestine and your doc felt they might look like crohn's. A good response to iron infusion does not change any of the thinking about whether those lesions are crohn's like. The biopsy should give a lot more information. ...Read more

First : First of all you need a surgeon who is willing to do an ex lap surgery. The only thing i think they may find is possible scar tissue and honestly I am not sure this would cause all of your symptoms. It sounds like you may be dealing with ibs (irritable bowel syndrome), however the vomiting is not characteristic. Have you or were you ever exposed to any chemicals or lived near an industrial plant? Is it possible that you are ingesting a substance that you are unaware of? Consider your surroundings and everything you take in. Is anything different in your life since this all started? If you think of anything discuss this with your doctors; every bit of information may be helpful in solving this puzzle. I hope you find answers soon. ...Read more

Fever of 99.6 for 7 days, left lower abdomen pain,bloated, occasional bleeding in bowel, diarrhea,food allergies, throwing up clean colonoscopy. Help?

Fever of 99.6 for 7 days, left lower abdomen pain,bloated, occasional bleeding in bowel, diarrhea,food allergies, throwing up clean colonoscopy. Help?

Get 2nd opinion: It almost sounds like diverticulitis which may not be detected by a colonoscopy. On the other hand, throwing up is not part of the symptoms unless you have a systemic infection which does occurs in diverticulitis. The counterpoint is that diverticulitis occurs usually in a much older age Food allergy is not associated with a fever. Suggest a consult @ an university center or with another GI. ...Read more

Possibly: I see that you have abdominal bloating. There can be many causes for that. An abdominal MRI gets a good look at the ovaries and other abdominal organs, but it is not good at seeing the insides of your intestines. If you have not had a colonoscopy, this may be a test your doctor orders. It looks at the inside of your large intestine and gives different information than the MRI. Hope that helps! ...Read more

Will a barium test show all of the stool in the small and large intestines? Is it typical to have one performed weeks before the first colonoscopy?

Will a barium test show all of the stool in the small and large intestines? Is it typical to have one performed weeks before the first colonoscopy?

No and no: Barium is a contrast agent which helps the visualization of the bowel during X-ray studies. When given as an enema, it helps for large bowel(colon) examination.Orally, it can help for small bowel evaluation. Neither route is useful for imaging BOTH large and small bowel.If the patient has taken proper bowel preparation measures, there is in fact no stool in the bowel to degrade the visualization. ...Read more
