I never used to drink coke or any other fizzy drinks. But I was desperate for some form of caffeine (coffee gives me horrible symptoms) and something sweet, so I was prepared to deal with the suffering after drinking coke.

From time to time, I cheat on my horrid diet because I have no energy and I still have some symptoms even while following a strict low histamine diet.

Anyway, I had no symptoms after drinking Coca Cola zero. In fact, I actually felt more relaxed, almost like it helped. I don't know if I'm imagining it, but my pulse stayed stable and I didn't even have reflux (I'm diagnosed with silent GERD/LPR).

What is happening??? I react to all kinds of healthy foods, including fruits and vegetables, even ones that are considered low histamine, yet I'm completely fine with coke zero. It actually feels calming. Why would that be? I usually react to almost everything, yet an unhealthy drink is making me feel better.

EDIT: I also forgot to mention that I let my coke zero go flat because carbonation makes me bloated and I've never liked fizzy drinks. Just to add some context and reply to a few comments: it doesn't make me feel "good". It just makes me feel... normal. Calm, like my body and mind aren't constantly overstimulated. It actually reminded me of how I felt before I developed histamine intolerance.

I'm already on antihistamines, DAO enzyme, supplements recommended by my allergist and a low histamine diet, but today is the first day my histamine intolerance has eased up a bit. I swear this should be studied lol. It doesn't feel like placebo, even the inflammation seems a little better.

I’ve had a histamine intolerance for a few years with worsening symptoms, cut out gluten and got on a low histamine diet which helped a lot at first. The hives came back a few months ago after briefly reincorporating gluten into my diet. I believe my intolerance for gluten was making me deficient in a lot of things, my medications were also not as effective when eating gluten. I was supplementing methyl b12, D3/K2, iron, C, and getting plenty of nutrients in through whole foods but it just didn’t seem to be helping anymore.

I cut out gluten again and at one point I tried to supplement methylfolate and it made me feel insane. Anxious, jittery, etc. I guess that should’ve been my sign that I could be deficient in folate, but instead I just stopped taking it. About 2 months ago I started supplementing folinic acid because I read it was much gentler on your nervous system and since then I’ve hardly broken out in any hives at all. I used to break out in hives from the temperature change of stepping out of the shower, a sharp wind on my skin, and skin irritation of any kind. That all has seemingly resolved in a matter of weeks.

Has anyone else improved after consistently supplementing folate?

Every time I go to the doctor/specialist, I feel gaslit (I know it’s not all doctors but it’s the ones that I’ve seen) which is a lot of why I’ve put a lot of effort into figuring things out on on my own.

I’m just curious if doctors ever look at these Reddit threads that confirm all these people with the same symptoms? I know that Reddit is not a medical journal but this is just something I’ve been wondering.

Did anyone else here develop histamine intolerance suddenly in perimenopause? I have had mild-moderate outdoor allergies only since my 20s but NO issues with foods. Now almost everything I eat gives me a headache, sometimes migraine level severity and it lasts for 36 hrs. The DAO is helping but I feel like it must have a hormonal basis and I really want to cure this. I’m seeing things online about estrogen dominance messing with mast cells but I was told that I had progesterone causing headaches because it’s taxing my liver. I’ve been off the progesterone for a week and the headaches are the same. The only thing that helps at all is the DAO.

I have a severe copper deficiency—0.66 mg/L (normal is 0.85–1.05).

No matter the form of copper, my levels don't rise, and I start feeling anxious and getting a migraine-like sensation.

Has anyone here ever had this problem and managed to solve it?

Hey, I was just wondering if anyone else experiences this- do different foods cause different symptoms for anyone? For instance, having kimchi gives me terrible rhinitis and eye mucus under the eyelids very quickly after eating it, whereas take out pizza gives me less rhinitis but moreso terrible brain fog and fatigue for the rest of the day and especially the morning after.

If so whats the mechanism behind this? Or is it possible that I’m dealing with 2 separate issues here? I also get the same reaction I have to pizza with celcius (zero sugar energy drink), so I think that rules out blood sugar spikes.

Does anxiety increase histamines? I’ve found recently when we’ve ordered new furniture (sofa, bed, bedding) I’m having palpitations, dizziness and fuzzy feeling all over my body and can’t breath. With this I’ve been SO anxious. Even the thought of going near any new item makes me have the same sensation…

I’m trying to figure out whether I’m dealing with a histamine flare or if I’ve actually picked up a virus, and I’d love to hear if anyone has experienced something similar.

I have histamine issues and normally take Pepcid daily along with Zyrtec. I was traveling this past week and completely forgot to take my Pepcid, so I ended up going about 5 days without it.

Now I’ve developed:
Sore throat (it hurts to swallow)
Lots of postnasal drip/throat clearing
A cough that’s mostly from trying to clear my throat
What feels like GERD/silent reflux

I know histamine can contribute to both postnasal drip and reflux, but these symptoms also feel enough like a regular cold that I’m second-guessing myself. I restarted my Pepcid today, but it’s too early to tell if it’s helping.

Has anyone here had a histamine flare that completely masqueraded as a viral illness? Especially with symptoms like postnasal drip, GERD, sore throat, or feeling like you’re coming down with something?

And the biggest question: What actually helped you?

I have a severe copper deficiency, but unfortunately, I don't tolerate copper supplements.

So, my only option is to increase my copper intake through food.

to those who replaced vegetable oil with animal fat how do you feel now with the symptoms

Hi! I recently had a horrible flare up of my chronic gastritis. This was on June 26th I woke up with the WORST heartburn I have in a while due to some prenatals. I have had chronic gastritis for about 4 years now and I was feeling fine up until that day. I had horrible heartburn and nausea I could barely eat for the next 3 days so my doctor prescribed 20mg Omeprazole once in the morning only. On day 1 I developed tachycardia which it’s happened before so I brushed it off. On day 2 I was feeling off balanced a bit and kind of floating and towards night time I got super itchy on my outer thighs. I took it for an entire week where I began to realize I was getting random itchy spots throughout my body. So my doctor prescribed 40mg pantoprazole once in the morning instead. My itching snowballed after that. I began getting super itchy everywhere and developed dermatographia and the wheals lasted 10-15 min after I scratched. I kept taking it for about 2 more weeks because my heartburn disappeared and I felt like I was choosing between heartburn and itchiness and the heartburn was pretty much the worse option for me until I could see my Dr lol. Well, I was advised to stop the pantoprazole so my final day taking it was this Monday morning. It’s now Wednesday and I’m still itching, I was fine until I ate some oatmeal I prepared last night with blueberries and walnuts. Does this sound like a histamine intolerance? Could PPIs trigger this reaction? I feel so much itchier at night or after showers like a crawling stinging itchiness. If anyone can offer me some advice I’d greatly appreciate it. Thank you!
