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.
