Signs of histamine intolerance

Signs of histamine intolerance





I have always suffered from bouts of repetitive sneezing during my childhood that one time my younger brother kept counting the times I've sneezed and the number amounted to twelve in a row. After the birth of my eldest son, my symptoms only worsened and asthma attacks were added to the list. I used to stock up on over-the-counter anti-histamine drugs, which I took almost daily for quite some time, not knowing that I was only harming myself, masking the symptoms and not addressing the root cause.


It wasn't until I changed my diet, got rid of all the chemical laden detergents, perfumes, body lotions and shampoos in my house; and started exercising that my symptoms almost vanished. It is really amazing how simple changes can affect the quality of your life.


The role of histamine inside our body

We need histamine to digest food, move the bowels, pay attention and regulate our immune response, however, when our ability to breakdown the excessive amounts of histamine becomes compromised we may develop an intolerance and we start suffering from a plethora of irritating health conditions.  


Signs of histamine intolerance

- Runny nose

- Migraines

- Obsessive Compulsive Disorder (OCD)

- Bloody nose

- Asthma

- Exercise-induced asthma

- Motion sickness

- Diarrhea 

- eczema

- Menstrual cramps

- Food allergies

- Rapid heart beat

- Seasonal allergies

- Vomiting

- Profuse sweating


- Sea sickness

- Depression

- Fatigue


 Causes of high amount of histamine in the body

- Deficiency in diamine oxidase (DAO) enzyme, which is responsible for breaking down the extra histamine that enters our body when we eat histamine-rich foods or foods that make our body release histamine.

Enzyme DAO is dependent on iron, copper, vitamins B6, B12 and C; and deficiency in any of these nutrients could result in the suppression of the enzyme, as well as elevated levels of blood histamine. 


Some of the medications that may deplete these nutrients include:

- Diuretics

- Hormone replacement drugs 

- Cholesterol-lowering drugs

- Deficiency in HNMT, which is another enzyme that breaks down histamine. However, unlike DAO, which works on an extracellular level, HNMT works on an intracellular level (reduces excessive amounts of histamine inside the cells). It is noted that HNMT needs vitamin B2 (riboflavin) to function properly.


Chemicals and the detoxification system 

Fragrances and chemicals need to be detoxified within the body and any issues with the enzymes involved in detoxification can slow down the detox process of these chemicals. This causes toxic levels of chemicals and fragrances to build in the body, which in turn can trigger high histamine levels and lead to an intolerance.

Chemicals that trigger histamine intolerance include

- Fragrances. These include many known hormone disrupting and cancer causing ingredients. They are often added to cleaning products, laundry detergents, perfumes, soaps, air fresheners, and scented candles. 

- Triclosan. This is an antibacterial product in many soaps. Yes, it kills bad bacteria, but it also kills all the good bacteria on your skin too. Triclosan is linked to  cancer and hormonal imbalances.

- Ammonia. Found in many glass cleaners and polishing compounds, it is a big contributor to asthma and bronchitis. 

- Chlorine. This is a bleaching agent and its fumes can cause breathing issues and skin problems. 

Other ingredients to watch out for include,

2-Bromo-2-Nitropropane-1,3-Diol, Didecyldimethylammonium Chloride, Alkyl Dimethyl Benzyl Ammonium Chloride, Ethanolamine, Formaldehyde, Glutaral Diethanolamine, Quaternium-15 and Triethanolamine.


Note: Look for natural fragrance-free products or try making your own at home using essential oils such as tea tree, lemon, grapefruit and eucalyptus.



Foods to eat and foods to avoid

Some foods such as avocado and ripe bananas are naturally high in amines, which is the form of histamine in foods, while others trigger histamine production within the body such as olives.
