Gut Health Clinic

What is the Gut Health Clinic?

The Gut Health Clinic is a naturopathic and holistic approach to gut support and repair. Our goal is to address the root cause using diet, lifestyle, supplement and herbal medicine. We also use functional testing (i.e. stool analysis, food intolerances etc.) when necessary. 

Most people are not aware that our gut is not just responsible for digestion; 80% of our immune system is in the gut and Scientists have found that gut bacteria produce many other neurotransmitters such as dopamine, norepinephrine, acetylcholine, and GABA, which are critical for mood, anxiety, concentration, reward, and motivation. The gut microbiome can cause changes in how our brains react, which can affect mood and energy! A happy gut = a happy you!

Addressing the root cause

Medication and basic dietary advice may work to suppress gut-related symptoms. However, it’s common that the underlying cause of the condition remains unidentified and symptoms can still flare-up. To see lasting change we must understand what is causing your symptoms and address the root cause. Root causes can include:

  • Imbalances in gut bacteria

  • Vitamin deficiencies

  • Infection

  • Food intolerances

  • Stress

  • Poor immunity

  • Autoimmune conditions

  • Digestive insufficiencies

  • Low-grade inflammation

  • Medication

Food Intolerance Tests Available

One of the most important things about Food Intolerance Testing is what you do after you get your results! Simply going off the intolerant foods is not enough. A gut healing programme is essential and this can take up to anywhere from 4-12 weeks depending on your symptoms and results. Below are the options available for intolerance testing.

Food Intolerance Test + Gut Healing Guidelines

I understand that cost is often an issue for people and Intolerance tests are renowned for being quite expensive. For this reason, I also offer the option to have the test done without the additional consultation. You can order the test kit online where you can carry out the test at home and send your sample back to the clinic to be analysed. We do our best to have results back to you within 3 days, along with gut healing guidelines.

How Does The Food Detective™ Work?

Food Detective measures IgG antibodies which may be linked to inflammatory conditions in the body, manifesting in a range of health issues. The technology used in the Food Detective is Enzyme-Linked Immunosorbent Assay (ELISA), the same laboratory method used for most hospital lab-tests for antibodies. ELISA is used daily throughout Ireland to test for serious conditions such as HIV, Hepatitis and most infectious diseases.

What's the difference between an Allergy and and Intolerance?

Food Intolerance

  • Reactions are usually delayed and symptoms may take several days to appear

  • You can be intolerant to several different food groups at the same time

  • Sufferers can experience multiple symptoms, from migraine to bloating, diarrhoea, lethargy and a generally feeling un well

Food Allergy

  • Reactions usually occur quickly, with a maximum of 2 hours after exposure to the 'reactive' food

  • The body's IgE immune system is activated by the immediate ingestion of the reactive food

  • Symptoms include: difficulty breathing, rashes, swelling, runny nose and anaphylactic shock These can potentially be life threatening

I have been avoiding a food for more than 3 months; will this food show up in the test?

It is possible that the antibody levels will have reduced significantly if you have been completely avoiding that food, and therefore highly likely that the food test will be unable to detect any antibodies. If you wish to test whether you can now tolerate the food concerned and feel that you can cope with the symptoms that may occur, include a portion of that food every day for 1 week before taking the blood sample. If you experience severe symptoms as a consequence, you should stop eating that food immediately and assume that you are still intolerant to it.

What is Leaky Gut Syndrome?

In some patients, inflammation or irritation of the intestinal lining allows partially digested foods to leak through gaps between cells in the intestinal wall into the bloodstream. This condition is called ‘leaky gut syndrome’ and patients with this condition typically have high levels of antibodies to multiple foods.  The symptoms of Leaky Gut Syndrome are many and varied and include: abdominal pain, heartburn, insomnia, bloating, anxiety, gluten intolerance, malnutrition, muscle cramps and pains, poor exercise tolerance, food allergies.

Do I have to avoid reactive foods for the rest of my life?

No. Once you have avoided the foods for at least 3 months, and have noticed an improvement in the symptoms, then you can start to gradually introduce the foods back into your diet. You should introduce one food at a time, with an interval of 4 days before trying another food. If you do not notice the return of any symptoms, then you can continue to include that food in your diet on an occasional basis.

How long do you have to avoid the foods?

It is recommended that you should avoid any food with a high IgG level for a minimum of 3 months. If you do not notice any improvement after this period of time, then you can assume that this food is not responsible for the symptoms.

I started to avoid foods from my diet, and now I feel a lot worse, is this normal?

This is a normal reaction for many people in the first few days after excluding a food or foods, due to ‘withdrawal-type’ symptoms. It is quite common to feel worse for a few days, but this phase soon passes and an improvement is usually noticed after a week or two.

Do I need to have a re-test after a few months?

Most people do not need to have a re-test, but if they would like another test we usually advise a period of 12 months in between tests. If the symptoms have improved and they have been able to successfully re-introduce the foods, then a re-test is unnecessary.
