What Causes Histamine Intolerance (and how to overcome it) 

For those of you reading this, it's okay, it's normal to feel lonely sometimes, if you're going through a tough time, keep trying, but never give up,

37 years of medication , multiple symptoms to deal with , a surgery And nobody has ever mentioned histamine intolerance. If you want to feel better you have to take responsibility and do your own research. Thank you for providing such useful information 😊 Game changer

MS functional nutritionist here and just want to say, this was an awesome video on Histamine Intolerance. You covered it all and explained it well!

My doctors are useless...

Most mainstream physicians will not tell you to get off of their synthetic drugs and to change diet and take healthy supplements. We're on our own with this and have to seek out information like that in this video. The mainstream community is honestly destructive and is all about money and stock prices. There is good advice in this video.

let go of eating tomatoes for a while, and take up drinking ginger tea, worked for me.

Be Our Own Doctor 🙏

Thank you so much. I’ve been suffering from unexplained itching all over my body for 4 years. 5 doctors later, she mention histamines. Then I found your videos and now I can cure myself. You are a life saver. I can now see light at the end of the tunnel.

This is about the most informative educational videos I’ve ever encountered regarding this ongoing issue. I am so thankful I inadvertently stumbled upon this video. Extremely knowledgeable and very well spoken. Other professionals that I’ve seen didn’t even come close to explaining the overall of histamine allergies. In addition, weren’t even as compassionate as this professional. Thanks for posting. Now, I feel there’s hope for all of us. God Bless!🤗💯%

Thank you. I learnt that after visiting dozens of ENTs , allergic specialists, inmonologist, only put me in antihistamines and nose operation, never worked, because they don't know all this, or if they know it don't care about patients. Root cause. Thanks ❤

I wish I had known you back when I was a child and my allergies were out of control. It's unbelievable how I've received more helpful information from your 13 minute video, than my parents and I received from so-called "top" allergists over the course of several years. Thank you!!

I have MTHFR genetic variant, and thats where I struggle with methylation and histamine intolerance. Really increasing supplementation of methylated B complex helped tremendously.

This is the best video on histamine intolerance I have seen so far. Thank you very much for sharing this.

Yes, well explained. My mcas was caused by stress. Over the years it got worse and worse. I never took the connection between the brain and the gut seriously, but stress and sleep deficit is the worst for me.

I always turn to social media for medical advice. The constant is thoroughly researched scrutinized investigated and accepted, much like the Joe Rogan podcast.

enviably concise and compassionate. A real find, thank you.

I've had mast fell activation disorder for the past year and a half and it can ge truly debilitating. I had to eliminate all sorts of food and for a few months I even had to order un-aged meat from the US (I'm in Canada). Took huge amounts of DAO supplements, etc., and have been on 20 mg anti-histamines all along. The thing that's helped me the most is intravenous Vitamin C. I still get IV infusions every 6 weeks (down from every 2 weeks) and will continue to do so fir as long as it takes.

This is EXTREMELY helpful in identifying where my conditions stem from and how they are all related. Thank you!!

I'm really happy for the pea sprouts tip, tthank you!❤

Hi been on Benadryl for the past three days sometimes taking six a day. I have bumps all over my body. I am so itchy that I can’t stand going without the Benadryl. I thought I ate healthy I quit drinking alcohol a year ago I thought I was doing the right things now I’m so itchy I cannot stand it, I’ve also been drinking Kieffer. Thank you so much for this video. I am so grateful. Now I know some of the things to avoid.

Nour is a genius. I'm not even half way through the video, and this is the most informative info I've seen on this topic!

I am SO grateful for you and this video! I have developed serious intestinal issues and food intolerance for the last year far wise than my regular allergies. My family is riddled with allergies. I suspect the genetic variation that you mentioned who do not produce the DAO as needed. I was convinced I am allergic to corn and wheat. I went to an allergist, for testing who seemed to know none of what you talked about. First stop should've been the dietician I guess. Thank you so much! Now i have a plan of action and will seek out the proper provider.

Jazzakhallahkhair, You covered everything in this video,I have been dealing with allergies for so many years and my symptoms were itchy scalp and hives around my neck. Will implement everything you said. May God bless you and family.

One of the best i have heard yet on histamine, TY

I suspected that antihistamines were setting up a vicious cycle for me and the info you provided confirmed that.

Oh’my goodness, I just saw an allergist and was prescribed 3 different antihistamines. I’ve taking different antihistamines my entire adult life and have several food allergies. I wanted to get another food allergy test since the last food allergy test was 30 years ago, but she was against the testing. I expressed my concerns for add more medication to my daily routine and possible tolerance to the medicines, but only negative feedback. The craziest part of this is, I’ve taken all of the newly proscribed medications and they don’t work for me. I am so grateful to find your channel! Thank you so much for sharing your knowledge.😊

I have been having these issues for 6 years already and my doctors always give me more and more medication . Now I started to do my own research and realising that none of my doctors or specialist ever did a test on food allergy or sensitivity nor looking at my guts 😱. I feel a bit angry in a way because they all chose to give me more medication that are barely helping anymore instead of starting at the base and do more research first 😢. I will try and find the right dietician and doctor and hopefully they will help to find the root of the problem instead of pumping me full of meds that don't work anymore except in high doses . Thank you for your explanation it really opened a new door for me ❤

I just went through 2 months of extreme stress, with my anxiety raging out of control, and am now dealing with painful , itchy eczema on the lower half of my face. I understood that stress was causing it, but this along with other informational videos and articles have lead me to believe this is a histamine intolerance issue. Thank you. I will be trying the diet to see if it offers me some relief.

It was a nice and informative video. The most important thing I learned is that Anti Histamine medicine creates more histamine.

You left out chemicals and EMFs as triggers. Yes, people, EMFs.

Ehlers Danlos Syndrome (EDS)(a type of hypermobility) often comes with Mast Cell Activation Syndrome (MCAS) and that itself often comes with Histamine Intolerance, sometimes Salicylate Intolerance, and, oxalate overloading I think. The most common form of EDS is called 'hypermobile EDS' or hEDS. Another thing it often comes with is POTS and most people with EDS and MCAS or HI have POTS. And histamine etc. symptomology can be different because of amplification of the effects of things like vasodilation or sympathetic nervous system dominance that happen to come with POTS. - Anyone out there with HI should see if they have hypermobility of any type. Do you have long fingers relative to your height and palm area, long thin limbs, thin wrists of which you might be able to touch your pinky to your thumb or even cover the nail of the pinky, tall height, can pull your fingers back behind 90º backwards or close to that, cracking joints, soreness especially at joints and ligaments and tendons, stiff muscles, loose joints, etc.

Thank you so much for talking about this, it’s quite overlooked!

Thank for explaining. My result for DOA is 9.6 um/l, this is all new to me but its ticking so many boxed regarding my health over last 10 yrs, working out what to do next so I will be working my way through your videos. ❤

wow, you point on short term histamines was so so helpful. that makes so much sense. wonderful content!!

I've had histamine intolerance for years. I learned more about it in this 12 min video than I have with anything else! I've already tried a number of things you mentioned, but my big AH-HA is that the steroid inhaler I use for asthma is blocking DAO. I recently discovered it is causing ALL my health issues,. I learned that it causes dysbiosis, which is related to histamine intolerance, but I didn't know it was also blocking DAO. I will now work towards getting off that medication. Doctors do not look for the root causes. We need people like you. Thank you!

My "aha" moment was when you said black and green tea can block dao! My son has postnasal drip and he loves ice tea. I assumed this was better for him than drinking soda!!!

I didn’t know to get tested for the conditions. I’m going to talk to my doctor.

I recently asked my allergy/asthma doctor why I've been on 2 rounds of allergy shots and on so much medication and still struggling. I showed her pictures of swollen eyes and rashes I get. I've done all the things I'm 12:42 supposed to do to make my home as allergy free as possible but until I take a zyrtec every morning I'm a mess. She tested for histamines and they were very high. She wanted to do a patch test but she's over an hour away from me and I have to go there 3 times in a week. Since retirement this year I'm not around mold that was a biggie for me and I'm doing better. A few months ago I was having a loud beating in my left ear. I had complained that my nose on the left side always felt like there was something stuffed in there and that in the morning I'd notice there was something that looked like something very swollen. The pounding was getting worse so I went to another doctor who put me on 2 different nose sprays and the pounding went away within 2 days. Also found that with stomach problems all my life the solution was to stop using mint toothpaste. I use cinnamon toothpaste and no more stomach issues after 30 some years.

Assalaamou alaykoum, Sister welcome, you are so needed in the neighborhood 😊. Let us talk about good food.

You are right. Antihistamines does not alleviate the symptoms especially when I get a bad flare.

Thank you very much for this ! very clear and concise, I'm sure it'll help a great deal !

I’m a new subscriber, thank you so much for all the videos on Histamine intolerance etc., appreciate you and your work! ❤

My intuitive healer was the one who diagnosed me with histamine intolerance. If it weren't for her, I still may not know what was causing all my symptoms. No traditional, western medical doctor ever helped me with that.

Thank you for such a clear and simple to understand video. For me, it comes and goes and besides some environmental triggers, I believe it is or has been very stressful situations. Life is more peaceful now and thus, I expect to have this situation improve greatly.

Thank you for this information. It’s greatly appreciated!

Processed foods, tomatoes, peanuts, vinegar, tamarind cause high histamine in some. Sour foods and raw milk or only milk too. Eat fresh foods.

Beautifully explained. Thank you Nour. I have horrible seasonal pollen allergies and have had it since I remember. So does my mother. Might be genetic but the info you’ve shared helps me understand why I struggle every morning during the allergy season. Our docs prescribe anti allergy meds and like to put us on them forever but I think it’s important to tackle the root cause and reduce dependency like you said.

A treasure of knowledge! Kudos!

Once i break out with hives they just dont go away and react even worse to anything i eat, i got on a 3 to 5 day water fast and my hives clear up, thnaks for the info i will deff implement it into my life style.

Sleep what is that ? 35 years EMS worker . Im 70 and one of those people who is allergic to many things and have been battling histamine since I was born. All ENT's want to do is treat Me with steroids and antihistamines both a dead end street. I enjoyed Your video and will try to follow Your advice.

So good to know that being on antihistamines long term can actually make things worse. This is the first time I have heard this, soooo... I need to make a change. I have been on the low histamine diet for 6+ months but still dealing with itching, and tingling in my legs, bouts of GI distress etc. I suspect I have always been a low DAO producer, but my doc does not even think to investigate these areas. He just writes me off as having chronic fatigue and offers no treatment or referral to a specialist to look into potential GI issues.

Dear doctor.. please stay around - we need people like you 😁 Thank you for a most informative video.

Excellent video on histamine intolerance

The aha for was the fact that steroids interfere with the DAO enzyme, a close family member has severe asthma and has a crazy amount of inflammation issues.

Thank you so much!...Just one video and explained it clearly.❤❤❤

I wondered if I was histamine intolerant years ago and focused on reducing proteins that were aged, fermented foods, and being careful of when I ate histamine releasing foods. I believe I have had SIBO for a long time. The western medical system won't test me for SIBO but gave me drugs for it when they didn't know for sure if I had it. I fired the Gastroenterologist for continuously gate keeping the functional testing I needed. I did my own research and although meat has the potential for having lots of histamines I have had no real histamine issues since going off plants and carbs. I believe that I have begun to heal the SIBO among other things since 4 months on the Carnivore diet. I will do this elimination diet for at least 6 months to get rid of SIBO, lose excess weight, and get rid of the painful oxalates in my joints. Then I will try to add back low histamine/low oxalate foods to see if they bring symptoms back. I will stay away from grains and sugars for good. My body cannot handle those at all.

Thank you for a very clear and concise presentation. Do you know if dietary antioxidants effect histamine levels? I suck liposomal glutathione (200mg daily). It increases morning sleep and empties the “histamine bucket” at the start of the day. It’s great for dreams too!

this was super easy to digest and straight to the point, pun intended. thank you so much!

Outstanding, concise and yet thorough presentation. Keep it up Nour!

I am a celiac. There is no cure. You can only manage the disease through your diet. But it's difficult. This becomes even harder as you age. Food choices become so restricted. Outbreaks happen over and over again.

Very informative & useful indeed. Thank you

Thank you so much. I am so overwhelmed with histamine and lactose intolerance at the moment 😭

Full respect for you Dr. Love this very informative thank tou so so much

Hi Nour Zibdeh: Thank you for this video. I am contacting you on behalf of my wife (73 year old Filipina) otherwise in good health except for recently-acquired Histamine Intolerance. Her diet for life has basically been vegetables, rice, with occasional shrimp or pork (common in the Philippines). When we eat out, sometimes we get spicy Indian food, which we love. We vacation regularly in Hawaii, and recently in Mexico to get some more sunshine. We live in Vancouver BC Canada and are thus starved of sunshine. We take supplements like Vitamin C, D, E, A, B-Complex and other good supplements like zinc, turmeric, kelp, etc. Occasionally during the spring-time, she may get 1 week of hay fever from the pollen in the air, which goes away quickly with diphenhydramine hydrochloride tablets for a few days. With our most recent vacation to Mexico, something must have happened, but we have not been able to figure it out. The all-inclusive resort had good food and clean water, from which we had no immediate symptoms. However, 5 days after being back in Vancouver in early August 2023, we sat in the sunshine for 15 minutes on the outside deck. After going inside and a couple of minutes later, she broke out in Hives that apparently were triggered by the sunshine. I was not affected. She has nice brown skin and has lived half of her life in the Philippines and half in Vancouver. We did further tests and determined that UVB would always trigger the same histamine response and hives. We have cut out different foods searching for the root cause, and cannot find a correlation between any particular food and the histamine-related hives. She is now taking histDAO supplements but they have not fixed the problem. I am thinking that she may have acquired some gut bacteria from the pork in Mexico, which is a good reason to avoid pork as I do. We want to fix this and get back to the way she was before our Mexico vacation. The other possibility is some reaction from the Mesenchymal Stem Cell treatment that she received from a clinic in Mexico, but this was her second treatment for her knee joints. Her first Stem Cell treatment from the same clinic was one year ago, and there were no problems at all. I don't think that her problem is diet related, except that something we did in Mexico has created this histamine intolerance, like a gut bacteria. I am an Engineer, so I am driven to find and fix the root cause directly and not simply cover up the condition. Do you think you can help and if so, how do we proceed? Please contact me at GarryAnderson@shaw.ca so we can work together. Thank you.

I am wondering your thoughts on hormones such as Estrogen dominance and histamine levels. I am wondering if this is my problem. Great video thanks

I would like to inform you that there is vegan DAO enzymes in Canada and US 's market that they made of legumes.

This video is very well done, thank you!

THANK YOU VERY MUCH! Mosquito bites trigger my histamine. The 'aha' moment, there were a couple, I never knew about mold. My apartment does not get any sunlight, the bathroom has mold on the ceiling, the kitchen has mold in the top and bottom cupboards and also on a part of the kitchen ceiling. The bedroom wooden furniture, board surfaces and cardboard boxes have mold on them. How to get rid of all these molds? I also didn"t know about the candida and parasites and virus enablers. Never heard of DAO. I did not know about the anti-histamines not being such a great idea. I"ve been taking the pills for the itchy bites which take months to heal and then leave black marks on my skin. Didn"t know the connection between the itching and hives and headaches. Didn't know diet could help to control histamine. Thank you so much again.😊

Thank you! I believe I have this condition! I have been so scared because my allergies have become quite severe. I am taking anti-histamines daily and life is almost unbearable. I have started eating more slowly now because I used to wolf my food down. I believe I have a build-up of histamine in my system. I am going to try the anti-inflammatory diet, avoiding the trigger foods and hopefully try the DAO enzyme to see if I can get some relief. Thank you for this wonderful information.

Very good and clear overview. I suspect I have a genetical Dao deficiency cause I've been suffering since childhood. I got hyves after I caught covid last year. Covid was just a throat ache but the hyves almost gone now after one year of low histamine and high vitamin c and quercetin. Glad the grenades are back available cause these help a lot in the cleaning up process.

Thank you so much for your explanation Very helpful to me to understand

Thank you for this information. You are very informative on this subject.

Even though I’m vegan, I had to give up bananas and avocados as huge histamine liberators. And obviously dump all the sauerkraut, kombucha and kefir. I also took C60 carbon oil which helped hugely for my energy levels and seemed to suppress the mast cell even if I had a chocolate binge! After 18 months I’ve reintroduced avocados successfully, but bananas still make me bloat painfully and my eyelid swelled.

Thank you for the informative video! I started off with IBS 30 years ago. Eventually I learned to manage that, but then instead of diarrhea when stressed, my mind would go blank. I also got hay fever for the first time in my life aged 36. At first, anti histamines worked. Now they haven't worked for many years. I also have adrenal fatigue. Last spring, I didn't have the usual allergy symptoms, but instead my adrenal fatigue got much worse and I became housebound. I know that my liver needs detoxing, but however gently I try, I crash.

This is very good information about the causes of increased histamine levels. I am frustrated though that food allergies are not considered as a cause of increased histamine. I am severely IgE allergic to 10 foods as well as environmental allergies. I constantly struggle with regulating my histamine levels and because of my food allergies, unable to take supplements. Why are food allergies not considered a cause of histamine intolerance? Thank you for your in-depth study and information.

Do you know how to heal GERD without medication? How to make the LES to function normal again?

One of the most comprehensive video on histamine intolerance! Thank you! Question: is being allergic to ragweed a histamine issue? What could be the underlying cause for it?

What is the zink/copper ratio targeted?

The type of histamines you take also play a big factor. Drugs liek benedril can cause dementia, with long term use. however Zyrtec usage in cases like uticaria even chronic uticaria is perfectly safe to take daily

Very informative. Thank you.

Thank you for this great information.

I’m hoping that this is the key 🔑

Thank you so much. This was so helpful

Thank you. After years research, you are providing the top actions and non medical options that have worked. Oh, except In still drinking coffee and tea. I didn’t know about that!

In the uk, 🇬🇧 go,private with this. No gp can help you. …. Had “something” since a very early age. But became aware of it age 7. Then my parents divorced, I didn’t take that well. Things gradually worsened relatively over the years with several flares along the way plus glandular fever late teens. No Dr could help except one who mentioned histamine in diet. After eliminating dairy and gluten as best I could I saw an improvement by my late 30s. But still couldn’t get to the bottom of it (lol) then in my 50’s a new Dr said I had fibromyalgia. An utterly useless diagnosis but she was the nearest to my symptoms and it did point me in one of several directions. One of which is histamine intolerance and only now, do I have a very qualified chiropractor ( one of many) and a dietician who are working together to help me with HI. If it wasn’t for my Chiropractor I think I’d be in a wheel chair more often than not. She’s well trained and has to understand the whole body system not just how to manipulate my spine back into the right position. Understanding why my spine sticks in the wrong place is part of the treatment, and we are treating HI. If you see my blood slides and the clumping of blood cells in different sizes it becomes clear why too. Lack of oxygen transference from sick blood cells can’t help. B12 deficiency evident in large blood cells. Stress clumping

Histamine is benefical in our body..we should heal the gut- gaps diet😊

Very helpful!

Excellent video but way too much information in order to tackle this problem. Like you said, if you have say SIBO, that a huge challenge on its own, and everything else is just an added complication. For someone that has SIBO (me) I don’t bother correcting my diet because I’m going to have problems anyway. You have to do first find out why you have SIBO, correct that first, then take the appropriate meds to eradicate the SIBO, and correct the diet at the same time. If you don’t know the cause of the SIBO, it will come back, and the histamine intolerance will be a problem again unless it’s a different cause, in which case the histamine intolerance will always be a problem. It’s rough being alive now 😅

Excellent video. Thank you.

Gosh why aren’t doctors like a PCP actually talking about his with their patients? The healthcare system in the US is infuriating

Thank you Doctor for an informative video. I used to get repetitive sneezing, nose block, watery eyes quite often. My mom has same issues, so it's in my DNA. I did allergy test and nothing came out. Finally, I gave up gluten, diary and sugar beginning this year and I am much better of. I observed that diary is the biggest culprit in my case. If I eat diary 2-3 times a week, I get this symptoms. What would you recommend if I happen to eat diary in a week to avoid this symptoms? Should I take a DAO supplement? Could you please give the names of few DAO supplements? Please advise. Thank you

Well done Ms. Nour, bromelain has helped me in so many ways.

I have peas growing in my garden right now. So I'm guessing the leaves will be fine to eat. I will definitely grow more. Right now, I'm drinking stinging nettle tea every night. Plus, I cleaned up my diet. I have the MTHFR gene, both copies. My body does not get rid of toxins, so gut issues are a huge problem. Thank you for this video. Most of my symptoms are gone, but I am still left with inflammation, so not completely. I am doing an all-out investigation.

Great information. Thanks!!

Miss Zibdeh, I been suffering from histamine intolerance since last december 2022. But history of histamine intolerence dates back to 2020. All these episodes started right after I recieved my covid vaccinations. First time was in 2020 and the syptoms were worse back then. Now the syptoms are manageable, but still annoying. I am taking DAO supplements and a probiotic from a company called viome, they take a sample of your stool and come up with a probiotic that is similar to your genetic gut DNA. I have been taking these probiotics since May and still no positive affects have been established yet. I believe when they tested for other syptoms they did not test for other factors that they could have taken into consideration, Like SIBO, etc. I am really frustrated about going through these episodes every 2-3 days and tired of taking Hydroxyzine. Can you find a solution to get me out of this mess? Really need help, Thanks Edgardo

Thank you very much for shating this!

What type of food should I start for a low histamine diet

Thank you for the information. Great video.

Hi there. I got a question if you don’t mind answering!. I do have severe seasonal allergies. I take pills every day until the season is over. My question is :Does consuming local honey has any benefits to help ease the symptoms? Thanks in advance

Had no idea mold and even dust can have a high effect on thr HIT. I hope this new finding will help me a bit
