Do You Suffer from Histamine Intolerance?

 

 

Could Histamine Be The Reason for Your Lingering Symptoms?

 


I wanted to write this blog post because we see many clients at the clinic suffering needlessly with histamine intolerance. Experiencing unexplained and frustrating symptoms? Could Histamine be the reason of your lingering symptoms?


Lets have a look…



What is histamine?



Histamine is a chemical involved in your immune system, proper digestion, and your central nervous system. As a neurotransmitter, it communicates important messages from your body to your brain. It is also a component of stomach acid, which helps you break down food in your stomach.



If you’ve suffered from seasonal allergies or food allergies, you may have noticed that antihistamine medications provide relief of your symptoms. Why? Because histamine’s role in the body is to cause an immediate inflammatory response. It serves as a red flag in your immune system, notifying your body of any potential attackers.



Histamine causes your blood vessels to swell, or dilate, so that your white blood cells can quickly find and attack the infection or problem. It is the histamine “buildup” that gives you a headache and leaves you feeling flushed, itchy and miserable. It’s important to understand that it’s part of the body’s natural immune response, but when you can’t break down histamine properly, you can develop what we call histamine intolerance (HIT).




Because histamine travels throughout your entire body in your bloodstream, histamine can impact your gut, lungs, brain, entire cardiovascular system and your skin, contributing to a wide range of symptoms making it difficult to identify.




What is Histamine Intolerance?




Histamine Intolerance is an intolerance of histamine ingested with food. It is caused by a deficiency of the histamine-degrading enzyme diamine oxidase (DAO), which is produced in your small intestine or an imbalance between histamine and DAO. It can be caused by genetic factors or is an acquired condition, often identified as a secondary condition to another.



Causes of High Histamine Levels



It is important to get a diagnosis, the exclusion of possible other causes such as genuine food allergy (IgE reactions), cross reactions, non-allergic reactions such as fructose malabsorption, lactose intolerance sorbitol malabsorption, or Celiac Disease and the exclusion of any other illnesses (such as cancer or a rare disease such as mastocytosis) from your GP or one of our Doctors at the clinic.



Other causes of high Histamine levels are:

 

 

  • Bacterial overgrowth (SIBO)


 

  • Dysbiosis- (i.e. histamine producing bacteria)


 

  • Leaky gut


 

  • GI bleeding


 

  • Fermented alcohol like wine, champagne, and b


 

  • Diamine Oxidase (DAO) deficiency


 

  • Histamine-rich foods



Do you see the link with your gut health? We find histamine intolerance in some individuals suffering from intestinal permeability, SIBO and dysbiosis.

 


Supplements



Some scientific researchers recommend taking supplements of Vitamin B6 and a higher dosage of Vitamin C as these are often deficient in individuals with HIT.




DAO food supplements




These contain the enzyme diamine oxidase but they do not in any way replace a low-histamine diet where you need to establish your threshold.



Some pharmaceuticals enhance symptoms



There are substances used in different pharmaceuticals that have a negative effect on the DAO. For someone with HIT that means that symptoms get worse, not better. Do not change medication before you have talked to your doctor, otherwise you may harm your health.


Only once you find out what is causing the symptoms in the first place can you start on the road to recovery.

 


 

SYMPTOMS

  • Stomach cramps

 

  • Stomach ache

 

  • Nausea

 

  • GERD/Acid Reflux

 

  • Vomiting

  • Headaches, similar to migraine

 

  • Runny nose and weepy eyes, especially after eating although there is no clinical sign of allergies

 

  • Fits of dizziness/vertigo

 

  • Extreme tiredness, feeling knocked out

 

  • Edema (swellings mostly appearing around eyes and lips, sometimes in the area of the throat)

 

  • Flushing of face and/or chest


 

 

Skin problems

 

  • Skin rashes, itchiness

 

  • Eczema

 

  • Urticaria

 

  • Acne (pimples)

 


 

Chest area


 

  • Asthma

 

  • Cardiac arrhythmia, such as a fast beating or irregular heart beat


 

Women
 

 

  • Dysmenorrhoea (severe period pains)

 

  • HIT symptoms go away during pregnancy and return after birth of child


 

Other symptoms
 

 

  • Chills and shivers

 

  • Low blood pressure

 

  •  Circulatory collapse

 

  • Sudden psychological changes (e.g. aggressiveness, inattentiveness, lack of concentration)

 

  • Sleep disorder

 

  • Irritability


 


 

Here are some general guidelines:

 

 

  • Avoid or reduce eating canned foods and ready meals

 

  • Avoid or reduce eating ripened and fermented foods (older cheeses, alcoholic drinks, products containing yeast, stale fish)

 

  • Histamine levels in foods vary, depending on how ripe, matured or hygienic the foods are

 

  • As much as it is possible, only buy and eat fresh products

 

  • Don’t allow foods to sit outside the refrigerator – especially meat products

 

  • Don’t eat leftovers older than 2 days old

 

  • Everyone has their own threshold; you will need to find yours

 

  • Cook at home. It will reduce your exposure and help you feel better faster

 

  • Make sure the probiotics you are taking are not Histamine Producers!

 

  • Eat Low Histamine Level foods

 

  • Avoid High Histamine Level Foods and Histamine Liberators.

 

  • Yeast – even though it does not contain histamine as such, yeast serves as a catalyst for histamine generation during manufacture. There is no yeast in the end product.


 

It is important to eat foods that are low in histamine levels in accordance to your threshold. In that objective, a food and symptoms diary is essential. Please always remember that there is no such thing as a “histamine-free diet”! Based on each individual threshold will result in stricter dietary changes for some and less for others.



What can you do if you have Histamine Intolerance?




Remove the high histamine foods for 1-3 months. You can add in a supplement of DAO by taking two pills at each meal, if needed.




You may not have to avoid these foods forever. It can be a short-term solution until your histamine or DAO levels return to their optimal ranges. Most importantly, find the root cause for the histamine intolerance.Depending on your uniqueness, you may find that you tolerate some foods better than others, so don’t despair as you learn important information about your body and take charge of your health!
