What are the symptoms of food intolerance?
Symptoms of food intolerance can vary widely among individuals but commonly include the following:
- Gas, cramps, or bloating: These digestive issues are often the first signs that your body is struggling to process certain foods properly.
- Heartburn: A burning sensation in the chest or throat can occur when food intolerances affect the digestive system’s ability to process certain substances, leading to acid reflux.
- Diarrhoea: Frequent, loose stools may indicate that your body is rapidly trying to eliminate foods it cannot tolerate.
- Headaches and Migraines: For some individuals, food intolerances can trigger headaches or more severe migraines due to inflammatory responses or specific food chemicals.
- Constipation:Difficulty in bowel movements might be experienced by some as a reaction to certain foods.
- Irritable Bowel Syndrome (IBS): Food intolerances can exacerbate symptoms of IBS, including abdominal pain, bloating, and changes in bowel habits.
- Eczema: Skin conditions such as eczema can flare up as a result of food intolerances, indicating an immune response to certain foods.
- Water retention: Experiencing swelling or puffiness in the body can be a sign of food intolerance, often due to the body’s inflammatory response to certain foods.
IMPORTANT DISCLAIMERS
1. MEDICAL EVALUATION FIRST
If symptoms are severe or new, see your GP first to rule out medical conditions.
2. ALLERGY DIAGNOSIS
Food allergies MUST be diagnosed by an allergist or immunologist. We do NOT diagnose allergies.
3. TESTING
Any food sensitivity testing used is: part of comprehensive assessment only, never used as standalone diagnostic tool, always interpreted by registered dietitian, and combined with dietary history and symptom tracking.
4. DIETARY MANAGEMENT
Any dietary changes we recommend are monitored for nutritional adequacy, include a reintroduction phase, are not unnecessarily restrictive, and include ongoing support and adjustment.

No. IgG testing measures exposure to foods (presence of IgG antibodies), not food intolerance or allergy. Testing is used as part of a comprehensive clinical assessment alongside:
• Detailed dietary history
• Symptom tracking
• Clinical evaluation by a registered dietitian
If recommended, food sensitivity testing is always combined with:
• Thorough clinical assessment
• Monitoring of symptoms over time
• Individual dietary trial (not blanket elimination)
• Nutritional adequacy checking
• Planned reintroduction of foods
We follow guidelines from NICE and the British Dietetic Association, which do not recommend testing as a standalone diagnostic tool.
No. Our approach uses test results as ONE PIECE of information. We do NOT recommend blanket elimination diets. Instead:
• We monitor your specific symptom response
• We encourage gradual reintroduction of foods
• We ensure your diet remains nutritionally adequate
• We help you identify your personal tolerance levels
This prevents unnecessary dietary restriction and eating disorders.
Key differences in our approach:
✓ Always combined with clinical assessment
✓ Follows NICE guidelines

True food allergies (IgE-mediated) require specialist evaluation by an allergist or immunologist. We do NOT diagnose or treat allergies.
If you suspect a food allergy:
✓ See your GP or allergist immediately
✓ Do NOT self-diagnose based on symptoms
✓ Allergies can be life-threatening
We can support nutritional management once an allergy is confirmed by a specialist.
