Quick answers
What is histamine intolerance?
Histamine intolerance happens when the body cannot break down histamine properly, leading to symptoms after eating certain foods or during times of stress or illness.
Histamine is a natural chemical involved in digestion, immunity, and the nervous system.
Symptoms can occur when levels build up faster than the body can clear them.
Some people with suspected histamine intolerance may also have mast cell activation symptoms (MCAS) or gut imbalance.
Common symptoms
People often seek support for:
- Flushing or skin rashes
- Hives or itching
- Headaches or migraines
- Bloating or IBS-type symptoms
- Sinus congestion
- Fatigue
- Anxiety or palpitations
- Food intolerances
- Reactions to fermented foods
- Symptoms worse around hormones or stress
Symptoms often affect more than one system.
How nutrition support can help
Targeted nutrition and lifestyle support may help:
- Reduce symptom flare-ups
- Improve food tolerance
- Support gut health
- Support histamine breakdown
- Reduce inflammation
- Improve energy and sleep
- Identify triggers safely
The goal is not long-term restriction, but improving tolerance.
When to see your GP
Speak to your GP if you have:
- Severe allergic reactions
- Unexplained weight loss
- Persistent severe pain
- Ongoing diarrhoea
- New or worsening symptoms
We often work alongside your GP or specialist.
How we support histamine intolerance
Histamine intolerance symptoms often have more than one cause.
Our approach focuses on understanding the whole picture rather than just removing foods.
1. Detailed symptom & history assessment
We review:
- Food reactions
- Gut symptoms
- Skin or sinus symptoms
- Hormone patterns
- Stress levels
- Sleep
- Previous diets or treatments
- IBS / SIBO / allergy history
This helps identify possible triggers.
2. Personalised nutrition approach
Depending on your symptoms we may use:
- Short-term low histamine approach
- Gradual reintroduction
- Gut-friendly diet strategies
- Anti-inflammatory nutrition
- Meal timing changes
We aim to avoid unnecessary restriction.
3. Supporting gut health & histamine breakdown
Histamine problems are often linked to gut imbalance.
We may work on:
- Gut bacteria balance
- Digestive function
- Nutrient status
- Inflammation
- Food tolerance
- Recovery after illness or antibiotics
4. Looking at root causes
Symptoms may be linked to:
- Gut dysbiosis
- SIBO or IBS
- Stress / nervous system imbalance
- Hormone changes
- Chronic inflammation
- Nutrient deficiencies
- Mast cell activation patterns
Addressing these helps reduce flare-ups.
5. Functional testing when appropriate
In more complex cases we may consider testing to guide treatment.
