Because you have histamine intolerance. It's not being allergic to food, per se, it's responding to the histamines in food and that your body produces in response to them, too. Histamine intolerance wreaks havoc on your digestive system so an ANTI-histamine helps your insides calm down.
I’m not sure what the answer is but I’m suffering from the same issues! It keeps me up all-night. Normally to get a little relief I tak Claritin for my seasonal allergies but I do keep Benedryl for emergencies! Today I took it and the pain subsided! I’m not sure if I eat something that I can as allergic to or what however the pain truly went away! I have to be careful because my mom died of esophageal cancer and my uncle of colon cancer! So it truly is my emergency reliever!
I have had issues with my stomach since I had my gallbladder removed. I would get these "episodes" of abdominal / chest pain, that wouldn't go away. I would get them often. I feel like stress brought them on or was a big part of it. I would go to the ER, and they would give me their "G.I. cocktail". which would take the pain away. But then years later, they stopped with the " G.I. cocktails". So after doing their ER work up every time I went in, they would send me home, not really knowing what was the matter with me. It would go away by morning. They eventually referred me to a Gastro Dr. Scope in both ends. But no answers. I then got referred to a Gastro Dr. at the University of Michigan. He did every test under the sun. You might say, I've had the "Million Dollar Work up". AND with NO answers... Every test... It's normal. I just wanted to know "what" was wrong with me. I was getting tired of these attacks. It would start with a headache, I'd get really tired, then later on that day, boom that very familiar feeling of pain in my epigastric, stomach pain that radiates to my shoulder, thru to my back. And nothing would make it better. Now don't get me wrong, I tried everything at least once, to get this horrific pain to go away. It would work on one episode, then the next one, it failed. I was so devastated. I just wanted some relief... Finally I had one last ER visit. They ended up giving me Haldol, and Benadryl IV. Now, I will NEVER take the Haldol again. It was like being on an acid trip... all I wanted to do was sleep. But the pain was gone, and the only thing I could figure was the Benadryl had worked. So I left the hospital that day. I ended up with another episode a few days later. I thought... what the heck, I will give the Benadryl another try. Well... it took the pain away within 15 to 20 minutes. I said, I will believe it works when it works at least 3 times in a row. So the next episode... I took the Benadryl again, and it worked. But I didn't like it making me tired. So I decided to try a non-drowsy allergy tab. Well I am glad to say...it worked. I now take an allergy tab daily. I have not had an episode in nearly 4 months. I'm hoping it keeps working for me. My oldest daughter told me I should go on the show "Mystery Diagnosis". Because it took so long to find something that worked for my painful episodes. But I actually do not have an actual Diagnosis for what ever it is I have. Thanks for listening.
My daughter has had abdominal migraines since age 5 a she is now 11. For years, she suffered horrific stomach aches that would strike seemingly at random, about once a week, and she would have severe pain and nausea lasting an hour or two and culminating in vomiting about 80% of the time. During these episodes, she would sit on the toilet with her head in the garbage can screaming inconsolably, not sure which end was about to erupt, and nothing, absolutely NOTHING, I could do would help whatsoever. It is horrible, as a parent, to be absolutely helpless and watch your child in agony like this. We suffered this situation for years - pediatric gastroenterologists, invasive tests, ER visits, many different medications - nothing helped. Finally in desperation on a hunch I tried giving her a benedryl during an attack. Miracle! It worked! And it has worked ever since. Benedryl stops the attack in its tracks after about 15-20 minutes. I told the doctor and he said it had to do with the antiinflammatory effect. He said it was fine to use it this way. It has never once failed to help. Her attacks happen only once every few months now - kids usually grow out of this condition - but it still works. There is definitely something to this, this idea of benedryl and stomach aches. I'm glad it helped you too.
It depends on the dosage. Benadryl also acts on the digestive tract because it involves seratonin reputake; seratonin is responsible for the contracture of your intestines amongst other things. Excess seratonin will also cause diarrhea. This article explains it well: http://thelastpsychiatrist.com/2009/01/treating_insomnia_with_less.html
Benadryl is an antihistamine. There are 2 types of histamines (that I am aware of) H1 being related to allergies and H2 being related to digestive processes. Therefore my guess is that benadryl is blocking some of the H2 histamines and releiving symptoms.
I suffer from reflux and a strange type of digestive illness which makes my entire body fall out of homeostassis, cause respiratory problems, diahhrea, vomiting, dehydrated, pale, and tons of other symptoms. Strangely, benadryl also helps me with these symptoms. It makes them go away within 20 minutes. It's really Nice because I have nearly died twice from this.
Well, the interesting thing about Benadryl is it CAN on occasion cause either diarrhea or constipation! Therefore, my guess is it's giving a little diarrhea type effect. ALSO, Benadryl can make people less anxious, make them drowsy and sleepy. So, there's the second plus for you, it relaxes you, and this will always make the body function more easily.
I do not think of this positive effect on your digestion as allergy-related, altho I can see why you think so. But generally an allergy is something that does not agree with you. Instead, I think of this Benadryl benefit as a side effect, as it is listed in rather long lists but rare lists of fairly minor side effects, which is why you can buy it over the counter. I know people who use it regularly as a sleep aid, so I can see no harm in continuing with taking it, but obviously do not exceed the dose recomended on the box you get it in.
I had a similar thing happen with another drug. I have no idea what it was, but I had a problem with some constipation out of nowhere. But then, since I do take a lot of medicines, I noticed it went away, so I figured it was one of my medicines. Recently I had all my meds changed a little, and I'm back with this stupid constipation, and am working on a daily solution to make it stop. Husband and I have lots of solutions, and I'm working on them!
I do not know why benadryl is helping you, don't know the particular item in with the medicine, nor any other reasons other than I've given, but I think its fantastic to get relief like you have after so many years. Keep us posted on how you're doing maybe one more post in a few weeks, just so we can keep up with the three cheers, or help you if it quits working (heaven forbid). GG
