Food intolerances

What are Food Intolerances?

Food intolerances occur when the body has difficulty digesting certain foods, often leading to digestive symptoms as well as wider physical and psychological effects. Unlike food allergies, which involve an immune response, intolerances are usually related to how the body processes specific ingredients such as lactose, gluten or certain additives.

It is normal to occasionally feel discomfort after eating, particularly with rich or unfamiliar foods. However, when symptoms are frequent, persistent or begin to affect daily life, it may suggest an underlying intolerance.

In our clinic, we often see that food intolerances can have a broader impact beyond digestion. They may affect energy levels, concentration, mood and overall wellbeing. The relationship between diet and mental health is complex, and symptoms are often influenced by multiple factors, including stress, gut health and lifestyle.

Food intolerances are not always straightforward to identify, and there is rarely a single cause. With the right support, it is possible to better understand your body’s responses and make informed, sustainable changes.

Signs & Symptoms of Food Intolerances

Food intolerances can present in a variety of ways, including:

  • Bloating or abdominal discomfort after eating
  • Excessive gas or changes in digestion
  • Diarrhoea or constipation
  • Nausea or feeling unsettled after certain foods
  • Fatigue or low energy levels
  • Headaches or “brain fog”
  • Difficulty concentrating
  • Changes in mood, including irritability or low mood
  • Skin issues such as rashes or flare-ups
  • Symptoms that improve when certain foods are reduced or avoided
