An Inflamed Gut is an Unhappy Body

What and how we eat is a crucial component of our wellbeing. We know that a poor diet will often result in poor health, but there’s a lot more to nutrition than what we put in our mouths. In fact, the state of our health is often tracked back not just to what we eat, but whether the food we’re eating is nourishing or damaging to our gut system.

Hippocrates said it best when he declared, “All disease begins in the gut.” The gut has a far greater impact on our daily life than most of us realize. The efficiency of our digestive system is integral to everything from the immune system, hormone balance, mood regulation, and brain function. And with every gut being unique, the food that helps one person may harm another.

Gut Inflammation

The lining of the small intestine can become inflamed or damaged from a variety of factors. When this happens, problems begin. Damaged cells can separate slightly, leading to increased intestinal permeability (more commonly known as Leaky Gut Syndrome).1 These ‘leaky’ cells allow undigested food or other substances like toxins, antigens, bacteria, and fungi into the bloodstream. The immune system then recognises these substances as ‘invaders’ and triggers an immune response, which typically results in chronic, low-grade inflammation – and the beginning of systemic health issues.

Antibodies help the body mount an immune system response (‘fight’) against foreign invaders. These specific antibodies are produced by the immune system in response to bacteria and viruses, but can also respond to food particles that have leaked into the bloodstream.

Different Antibody Responses:2

  • IgE responses are a “true” food allergy as they occur immediately and can involve serious inflammatory symptoms such as swelling of the mouth and anaphylaxis.
  • IgA and IgG reactions can take hours to days to appear on the skin or in the gut, causing nausea, constipation, diarrhea, brain fog, or skin irritation (especially worsening pre-existing conditions like eczema and psoriasis).

The first step in treating food allergies or sensitivities is to identify the cause of the reaction. Food sensitivity tests can run extensive panels of common foods to assess the body’s immune reaction in the form of IgE, IgG and IgA reactions. Once you understand the results of a food sensitivity test, this will help inform dietary healing protocols including the elimination of inflammation-triggering foods.

Unfortunately, most of us can’t discern the foods that are nourishing us from the ones causing inflammation.

The symptoms of gut inflammation:3

  • Constipation and/or diarrhea
  • Cramping, bloating and gas
  • Heart burn
  • Food allergies or intolerances
  • Aching joints
  • Acne, eczema, psoriasis
  • Headaches
  • Brain fog
  • Fatigue
  • Poor immunity

Over time, chronic gut inflammation has been observed in a wide range of disorders – nutritional deficiencies, hormonal imbalances4, autoimmune disorders5, inflammatory bowel diseases, and depression.6,7

Gut Testing

Getting the gut back to optimal functioning is perhaps the best starting point to revamp your overall health and wellbeing. Gut rehab, just like any other system, begins with a comprehensive and accurate understanding of the gut’s current status. Reviewing the journey of food, we can see that the gut is a complex system where many things can contribute to inflammation and poor function. Laboratory tests like food sensitivity testing and digestive mapping, are invaluable to creating a personalized and effective plan to reverse damage and support gut function.
