Could my doctor diagnose celiac disease with a colonoscopy?

Could my doctor diagnose celiac disease with a colonoscopy?

Probably not: Celiac disease can be diagnosed by small intestine biopsies, done through an endoscope through the mouth. Colonoscopy comes from the other end (the anus) and probably wouldn't be able to get a diagnostic biopsy of the small intestine. ...Read more

It could be possible that a colonoscopy diagnose celiac disease?

It could be possible that a colonoscopy diagnose celiac disease?

Possible: During colonoscopy, quite a number of physicians reach the terminal ileum, the last part of the small intestine. Celiac disease affects this part of the small intestine, so the physician can see the changes in the lining of the gut and confirm the diagnosis with biopsies taken from that area. ...Read more

Is it possible for a toddlers blood test to be negative for celiac disease but upon endoscopy or colonoscopy be found to indeed have celiac disease?

Is it possible for a toddlers blood test to be negative for celiac disease but upon endoscopy or colonoscopy be found to indeed have celiac disease?

Possibly: If the correct test was done (measurement of IgA antibody to human recombinant TTG is recommended for initial testing for CD by NASPGHAN) and was negative, AND if a child has chronic diarrhea or failure to thrive OR if they have selective IgA deficiency or a + family hx of CD, a biopsy might be recommended. Consult with a pediatric GI physician if this is the case. Best of luck! ...Read more

I'm 38 female, smoker, have celiac disease but do not stick to diet, I've had one colonoscopy, found ONE sessile serrated polyp 9mm, should I worry?

I'm 38 female, smoker, have celiac disease but do not stick to diet, I've had one colonoscopy, found ONE sessile serrated polyp 9mm, should I worry?

Worry is relative!: If they never told you, you need to be aware of a fact. Every time someone with celiac disease consumes gluten, their immune system creates new antibodies that attack various tissues in the body. Your symptoms may be readily apparent or subtle, but they will eventually lead to more problems. It is hard enough to remain gluten free when you try, since it can be found in unexpected items. ...Read more

Is there any relation between ibd and celiac disease? How is celiac diagnosed? (since I think colonoscopy is for large intestine only?)

Is there any relation between ibd and celiac disease? How is celiac diagnosed? (since I think colonoscopy is for large intestine only?)

Similar symptoms: Ibd and celiac disease have been reported together in some patients. Some patients with ibd have also reported a relapse in symptoms on gluten free diet, but a direct relationship has not been definitively established. Celiac disease is diagnosed with the combination of upper endoscopy, duodenum (small intestine) biopsy, and blood test for celiac antibodies. ...Read more

I am having a colonoscopy in a week & have celiac disease, for colon prep I was told to limit my food a week before to a low fiber diet, whait's that?

Low fiber diet: Meaning less of foods with high fiber content, to avoid build up of waste in the colon before the procedure, usually it is soft diet, avoid lots of fruits, vegetables, green salads, etc, ask the team who will perform the colonoscopy, they would provide you with exact diet regimen needed, good luck with the procedure ...Read more

I have celiac disease, and also cannot gain weight, is apetamin safe to take, one doctor said it is not safe at all.

I have celiac disease, and also cannot gain weight, is apetamin safe to take, one doctor said it is not safe at all.

Ok but: This drug is same as Periactin- an antihistamine we used to use to stimulate appetite. HOwever it does cause most people to be drowsy and thus not the safest drug to choose. You likely have problem getting food without gluten and thus it is time for you to consult a dietitian. Make sure that you don't have another disease condition which may cause weight loss. ...Read more

My doc ordered 4 blood tests testing for celiac disease. I live in rural Iowa. They had to sent to Mayo. Why is this? What are the tests?

My doc ordered 4 blood tests testing for celiac disease. I live in rural Iowa. They had to sent to Mayo. Why is this? What are the tests?

Varies: There are a number of tests that are used to screen for celiac disease. The tissue transglutaminase IGA is one of the more dependable, usually ordered with an IGA level. There are others, and the delicate nature of the tests requires that they be done in a facility that does them often to be reliable. Local hospitals rarely have the volume to invest in the specialized equipment. ...Read more

Doctors, what is the difference between celiac disease and gluten allergy?

Doctors, what is the difference between celiac disease and gluten allergy?

Sxs/mechanism: A true food allergy goes through the immune system and causes a sudden, potentially life threatening reaction (anaphylaxis) which includes hives, swelling, breathing sxs, GI sxs, heart sxs, nasal/eye sxs. This can be diagnosed by an allergist. Celiac is a different immune response to gluten in the gut. Symptoms can be more subtle (stomach sxs and others) and initial eval involves a blood test. ...Read more

I have celiac disease and I'm on a gluten free diet. Should I be seeing a doctor for my celiac disease? If so, why?

Yes, you should: You don't mention how you were diagnosed. If you are doing well and initially had an endoscopy that confirmed the diagnosis, there is no urgency. Still you should be seen once a year. If you have never had an endoscopy, you should see a gastroenterologist. ...Read more

I am so worried. My kids only need to see the doctor for sports physicals. Now one has celiac disease. What should I say, in terms of effects on health and well-being?

I am so worried. My kids only need to see the doctor for sports physicals. Now one has celiac disease. What should I say, in terms of effects on health and well-being?

Be honest: Celiac disease can in some cases affect performance with fatigue and side effects of medication. Sports physicals are designed (hopefully) to try and find out about serious risks such as impending heart stoppage, asthma and aspects of physical fragility which would render athletic performance hazardous. Celiac disease is not one of those. ...Read more

How does it take for a doctor to test for celiac disease and gluten sensitivity?

How does it take for a doctor to test for celiac disease and gluten sensitivity?

Depends on the test: And the lab doing the testing. There are a number of lab tests for diagnosing celiac disease. Many labs do not perform the tests in-house but send the specimens to a reference lab. Based on the results of initial testing, additional tests may be needed. Therefore it is not feasible to give an exact timeline, but all of the tests can be completed in a matter of days. ...Read more

Celiac disease. My doctor put me eat bread with gluten and took blood sample. Two days fatigue, no sleep. Celiac rash. This is wrong! What can I do?

Celiac disease. My doctor put me eat bread with gluten and took blood sample. Two days fatigue, no sleep. Celiac rash. This is wrong! What can I do?

It IS wrong: Unfortunately, insurance companies won't pay benefits unless the blood work is positive, and it will usually not be positive if you are already under treatment. So celiac patients are forced to become sick once again. The US health care system is horribly dysfunctional. I'm sorry this happened, but your physician is as trapped in it as you are. ...Read more

Celiac disease, 2 mos on diet. Unresolved severe fatigue, muscle aches. Ferritin= 5. Doc said not anemic so iron supp not needed, won't help symptoms?

Celiac disease, 2 mos on diet. Unresolved severe fatigue, muscle aches. Ferritin= 5. Doc said not anemic so iron supp not needed, won't help symptoms?

Ferritin of 5 = low: That is a very low ferritin, so this is most likely iron deficiency, though you may not yet have anemia. With this ferritin it is likely you eventually will get anemia. Iron supplementation is generally safe but also look into iron containing foods to increase intake. ...Read more

Can you request to be tested for celiacs disease from your primary care doctor?

S/he can start it: Initial screening is simple, using your history & exam to validate the need for blood tests. (insurers may not pay for tests unless the need is established)The initial blood tests narrow the group of people that have some symptoms down to those who are most likely to have it. Further confirmation by more invasive tests by a GI specialist may then bee needed. Your primary can coordinate this. ...Read more

How do I talk to my doctor about testing me for celiacs disease? Maybe that's making me bloat up?

Just ask: The screening tests for celiac are a simple blood draw that any primary care doc can order. Specific tests can point in that direction & if so a further test through a GI doc would be needed. You need to be consuming gluten for the 3 weeks prior to testing for it to be accurate (at least a slice of regular bread/d}. ...Read more
