Ct Scan Contrast

11 posts in this topic

I had to spend a couple of days in the hospital. I brought in my own food but seem to have gotten badly glutenated somehow. I havent been this bad since diagnosis! I had to have a CT scan with injected contrast. I asked the nurse what the ingredients are but she couldnt find out. I know gluten can sometimes be in the oral kind but what about the injected kind?

I don't think so. Gluten containing ingredients can supposedly be found (though I've never actually seen it) as binders in pills. The very last thing they want in any injected medication is "binding". Actually, from what I've read, wheat starch is so heavily processed for medical purposes that it shouldn't matter even if it is used in pill; it's supposed to be pure starch, no gluten.

"should be" is a key word, however, it can still cause a reaction.

I'm really at a loss then. I keep racking my brain but I can't think of what else it may have been. There was the CT scan, some other scans without any injection, blood tests, blood sugar tests, iv saline solution...All should be ok. What am I missing? Maybe the bedding?

Did they have you drink anything for the scan too? Some of the oral ct scan contrast can have gluten. As for the IV contrast there is no gluten but it is iodine based. Your nurse probably didn't know the ingredients but the CT technologist should have been able to give you all the information on the IV contrast. We have to keep the package insert in our radiology dept. and also in pharmacy. What symptoms were you having after? It is possible you could have reacted to the IV contrast but not because of gluten.

Thank you Roda. They didnt have me drink anything. They hooked me up to an IV and had me fast for quite a few hours. Then they took me to have my heart checked, then a chest x-ray and then to the CT. They injected the liquid into my arm and then felt all warm for a moment. All normal. The only other things they did that day were took blood, blood pressure tests and later in the evening blood glucose test from a pin prick test.

I was feeling ok but the next morning I was feeling like crap. Absolutely exhausted, couldnt even keep my eyes open. Felt like I was going to vomit, had loose bowels, rash on my face etc. Slept most of the day because that's all I could do. I could only keep my eyes open for about 15 min at a time. By evening though I was feeling ok. The ddoctor thought it might have been a reaction to the contrast.

That night they gave me two steroid pills before bed. The next morning though I felt like crap again. Loose bowels, feeling like I was going to vomit, brain fog etc. The doctor said that because it was happening again it wasnt a reaction to the contrast and that if it countinued I should come back later in the week. As I was getting into my steet clothes to leave the hospital though I noticed that I had 3 patches of hives. All the symptoms were like I had been exposed to gluten but we had brought in our own food and drinks.

Hard to tell if it was the IV contrast, but not impossible. What has my intrest is the rash you had. As for the hives the following day, could those have been from the steriod pills they gave you? It still is a possibility that your reactions were from the IV contrast though. If you are uncertain, mention it if you ever have another CT scan where they may need to use it. If you want to be cautious then your physician can always order you premedication beforehand to lessen the chance of a reaction.

You also mentioned that you had a heart test. Did you have by chance a nuclear medicine stress test? They inject you with radioactive isotopes and other things for that too, but I don't know a whole lot about those.

Unfortunately we didnt notice the hives until the doctor on the floor was gone from doing his rounds and were only able to discuss it with the nurse. She wasnt sure what was going on. They've since gone down. The just did a quick heart test before the CT for some reason. I dont think they did a nuclear medicine stress test. I've been slowly gaining weight for 3 years and they dont know why. They were testing for Cushings as well as other things. The rash was only on my chin, cheeks and mouth. (like what happens when I have a gluten problem)

This is just a streatch but do you get DH? From what I read on here iodine can flare that up. Just a thought since the contrast is iodine based.

Great minds think alike. I have DH and my doctor wouldn't let them use the injected contrast when I had a scan and ordered gluten free liquid to drink. I had been severely glutened when I had a previous scan done with the regular barium drink.

I'm usually ok these days but had had food poisioning a couple of weeks ago that put some stress on my system. It was the tiredness, rash, hives etc that made me think gulten before. But maybe the sheets on the bed or someone else had come into contact. I guess there is no way to know but if I ever have a CT scan again I know to let them know that I felt like crap after!

    • Italian pasta
      Get some celiac travel cards to print off and keep in your wallet.  Present them to your waiter.   http://www.celiactravel.com/cards/ Tell the airline that you need a gluten free meal, BUT take food with you because odds are the airlines will make a mistake.   As far as the wheat pasta.....some folks say the wheat is different.  I personally think they are kidding themselves.  There is no scientific proof that I have found to support this theory.  (Anyone want to present such data?)  Italy, from what I heard is great for celiacs.  I'll know for sure this summer!  I'll be there!   As usual, we plan on bringing some packable food, but we are good at shopping at grocery stores for food and picnicking when traveling.  I expect foods at grocery stores to be clearly marked as they were in Great Britain since they are part of the EU.  
    • Villous atrophy with negative tTG IgG/IgA, high Gliadin IgA!
      It looks like you have a few options that you need to consider pursuing: 1.  Get back to your doctor and tell him to figure out what's wrong with you.  Take a friend because it helps to have someone listen and take notes who is not the patient.  Get copies of all lab reports and doctor notes always and keep a file on yourself to share with future doctors or to monitor your progress.   2.  Ditch this GI and get a new one (SIBO is real per my celiac savvy GI).  Take a friend with you.   3.  You say you are lactose intolerant.  Experiment by going lactose free for six months -- not just a few days.  This will help to promote healing and help determine if milk (lactose or proteins) are causing villi damage and not gluten. 4.  Recognize that some celiacs test NEGATIVE to antibodies.  Per Dr. A. Fasano and Dr. Murrary, based on their clinincal experience and recent data just published, they estimate that 10 to 20 percent of celiac disease patients test negative to the serology screening test. That means consider yourself a celiac and stop your gluten intake for at least six months.  Normal vitamin and mineral levels do not rule out celiac disease.   5.  Recognize that you can multiple reasons for villi damage.  That's why a second consult with a celiac savvy GI is important.   Good luck!    
    • Continued Symptoms
      Try keeping a food and symptom diary.   She could have allergies or intolerances.  But, again, I am not a doctor!  I am healed from celiac disease, but I still react to certain foods and have allergies.  Those will probably never go away as I have been plagued with them all my life (as my siblings have too).  She could have a milk protein intolerance and not just lactose.  Eliminate all dairy too see if it helps.   Speech really normalizes by the age of 8.  I can not say if your public school will evaluate her.  My home-schooled friends are still monitored by the state and receive state funding.  So, I would assume they would receive all the same benefits.  Try calling.  
    • Weeks in and feeling no better
      Let me tell you that based on what people post on this forum, it takes MUCH longer to heal.  In theory,  it should just take a few week on a gluten diet to promote villi healing.  Your body is constantly regenerating new cells in your gut on a daily basis.    Why the delay?   First,  it takes a long time to really master the gluten free diet.  So, in the beginning, dietary mistakes are often made which can delay the healing time.  Second,  celiac disease is an autoimmune disorder triggered by gluten causing a "flare-up" which can be measured by the level of antibodies in your system.  Antibodies can take weeks, months or years to come down.   Third,  there's the type of damage done to your body to consider (e.g. bone damage, depleted iron levels).  Usually anything neuro takes much longer to heal. Has your doctor checked you for nutritional deficiencies?  If not, ask.  You might be really low on a vitamin or mineral.   You could be low on digestive enzymes (actually they can not be released in a damaged gut).  So even when eating gluten free foods, your body is not digesting and absorbing the necessary nutrients.  You could help the healing process by taking gluten free supplements and enzymes.   But it is best to see what you are actually deficient in.   Most of these deficiencies resolve with time. Finally, my parting words of wisdom (as passed on by many of our members), is patience.  I know.  Hard to be patient when you want to feel well, but it will happen.   Hang in there!  
    • Gluten and panic attacks
      Now if everyone out there who probably has a gluten problem adopted your attitude, they would be having a much better life.  After over 10 years gluten-free myself, who really cares about gluten pizza? I go months without gluten free pizza, which is very good by the way, and I am not an emotional wreck.  Imagine!  Glad you feel better and yes, it was the wheat!

      Hi There, I don't know if there is a place for videos in the forum. I just watched "The Truth About Gluten" I think it is a good video. I would like to share it somewhere but don't know where it should go. Any help would be greatly appreciated.
      Here is the link if you have never watched it.

      Hello! I am new to this Celiac website... Is there anyone out there with Celiac AND extensive food allergies? My allergies include shellfish, dairy, eggs, cantaloupe, kiwi, mango, nuts, oranges, red dye, and more I can't think of. I went to the allergist about a year ago to see why I wasn't feeling well, and once everything was eliminated, I still didn't feel well. We did more testing to find out I had celiac as well as allergies to cattle as well as rye grass (I live on a farm basically). This was back in January 2016. I recently had my endoscopy with the gastroenterologist a week ago. I have no idea what to do or what to eat... So fish and potatoes for me!
