Do you experience unexplained headaches or anxiety?
Do you have skin rashes?
Do you have flu symptoms?
Irregular menstrual cycles?
If you answer yes to any of these questions, you could have histamine intolerance.
Histamine intolerance can be really frustrating as it's difficult to understand where the symptoms come from. I know what I am talking about as I had histamine intolerance for a long time. Fortunately, I was able to understand the issues and determine what the underlying cause was.
But first, what is Histamine?
Histamine is a chemical present in your immune system, your digestive, and your central nervous system. As a neurotransmitter, it communicates important messages from the body to the brain. It's also a component of stomach acid that helps to break down the food.
What is histamine intolerance?
It’s the result of the disequilibrium of accumulated histamine and the capacity for histamine degradation.
What are the symptoms of histamine intolerance?
Diarrhoea
Difficulty falling asleep
Anxiety
Headaches
Flushing Abdominal cramps
Irritables syndrome
Nasal congested, runny, or itchy nose
Sneezing
Shortness of breath
Hives or red, raised, itchy, burning bumps

What causes high histamine levels?
Allergies (IgE reactions)
Bacterial overgrowth (SIBO)
Leaky gut
Gi bleeding
Diamine oxidase (DAO) deficiency
Food rich in Histamine
Histamine is produced by the body but it also found in food. It can release more histamine in the body but also block the enzyme DAO (diamine oxidase) that breaks the histamine in the body.
What makes the DAO lower in the body?
Airway medication
Heart medication
Antibiotics
Antidepressants
Diuretics
Pain medications
Gastroesophageal reflux disease
Alcohol
Vitamin B-6, vitamin C, copper, or Zinc deficiencies
Extreme or chronic stress
Injury or trauma
Leaky gut
Gluten intolerance
SIBO
Genetic mutations
DAO blocking food:
Alcohol
Energy drinks
Black tea
Mate tea
Green tea

How to test for histamine intolerance
Elimination diet: can be done by removing the food high in histamine for 30 days and reintroducing them one at a time.
Blood testing: A blood test can be done to evaluate the level of DAO. A positive test should show that a high concentration of histamine is present in the body and as well as a low amount of Dao.
Address the Root Cause of Your Histamine Intolerance
The key to overcoming histamine intolerance is to identify the root cause of the issue. In my experience, I find that histamine intolerance is often caused by a gut health issue and more particularly caused by a SIBO.
Other common culprits behind histamine intolerance are leaky gut and gluten intolerance.
