Our journey starts with U.

Our Gut Health Clinic helps you overcome IBS, leaky gut, constipation & chronic digestive conditions.

Healing the gut is like any complex problem-solving activity; you need to look beyond the symptoms and focus on the underlying root cause.

Suppressing symptoms may result in short-term health improvement, but your original symptoms are likely to come back, and often progressively worsen, unless the underlying root cause is identified and treated with a more holistic approach to healing that is tailored for you.

Your Gut Feeling

As many as 85% of adults in the western world suffer with some form of gut problem annually. Irritable Bowel Syndrome (IBS) is becoming a significant healthcare burden worldwide, affecting around 11% of the global population.

Apart from the ever-increasing incidence of primary gut disorders, an unhealthy gut can contribute to a wide range of diseases including obesity, diabetes, autoimmune disorders, hormonal imbalances, chronic fatigue, autism, depression, and cardiovascular disease.

Therefore, not only is identifying the underlying root cause critical to eradicating symptoms, it is also critical to improving your long-term health.

Do not Accept IBS as a Diagnosis

As far as the mainstream approach to the gut is concerned, as long as you have abdominal pain and/or bloating, with constipation or diarrhoea, but do not have signs of inflammatory bowel disease or cancer, you are given the label ‘Irritable Bowel Syndrome’.

IBS is technically not a diagnosis, rather a description of symptoms. Furthermore, the reason that an underlying cause and treatment for IBS is hardly ever identified for most people, is that you cannot find a single cause and treatment for something that is not one condition.

With the development of technology, leading to better insights in to the gut ecosystem

Our highly specialized functional gut testing, with significant supporting research, can actually identify and subsequently help us treat the specific underlying disorder. Meaning the IBS ‘life sentence’ can be lifted, allowing our clients to get back to normal life.

What is Constipation?

Constipation is one of the most common symptoms we see in our clinic – affects up to 25% of the population – And whilst most people think of constipation as just an annoying symptom, it can also be the root cause of other symptoms and conditions, including fatigue, weight gain, low mood, and many more.

Constipation is a symptom, not a diagnosis

Many clients come to us having been labelled for many years as having IBS or functional constipation and encouraged not to look any further. We almost always find an underlying and treatable condition.

Chronic constipation is often not resolved with simple, conventional remedies like drinking more water and eating more fibre. This does not work for those people who have more going on in their gut, much to the confusion of patients and their family.

What is exactly at the root cause?

If you only know the symptom, you can only focus on suppressing those symptoms in the short-term. Using laxatives is a great example of only temporarily suppressing the constipation symptom.

Common causes include

  1. Food allergies and sensitivities
  2. Microbiome imbalances
  3. Gut infections & inflammation
  4. Neurological issues

So what next?

Healing constipation is a journey. Our Functional Medicine Team will work with you to help identify and treat your specific underlying causes, and put you on a nutritional & lifestyle plan to optimal health & wellness.

Leaky Gut, fact or Fiction?

The lining of the gut is made of millions and millions of cells. These cells join together to create a tight barrier that acts like a security system and decides what gets absorbed into the bloodstream and what stays out. ‘Leaky Gut’ or intestinal permeability is a consequence of an unhealthy gut, leading to a weakening in the gut lining.

When the bowel lining is altered or damaged, larger, undigested molecules are absorbed into the bloodstream and cause further inflammation, consequently preventing the absorption of beneficial nutrients.

Whilst this is a relatively new discovery, there are strong links between leaky gut, inflammatory digestive conditions and a number of wider health issues.

Understanding the gut

Since the discovery in 2000 of key regulators of intestinal permeability, better insights in to the ecosystem residing in our gut has provided support for the concept that a disruption of the gut environment may cause the onset of leaky gut and the exacerbation of many health conditions.

More accurate and reliable testing

Our highly specialised functional gut testing, with significant supporting research, can actually identify and subsequently help us treat your underlying gut disorder. We utilise a unique Intestinal Permeability and Absorption (IPA) test focused on assessing intestinal permeability & damage, gut function, intolerances and the health of intestinal villi.

What causes a leaky gut?

Increased intestinal permeability is primarily caused by the over-consumption of alcohol and processed drinks, pharmaceutical drugs, and diets consisting of low-fiber, high-fructose, preserved, and processed foods. Other factors such a stress, sleep disruption and intensive exercise has been shown to increase gut permeability.

Leaky gut and inflammation

Gut inflammation is typically accompanied by:

  1. Impaired gut barrier function
  2. Microbial imbalances
  3. A hyperactive gut immune system

In other words, a compromised gut barrier, leading to increased intestinal permeability is required for gut inflammation to occur. However, the wrong gut bacteria, disrupted gut motility, or other factors (diet, medications, stress, etc) may be responsible for causing leaky gut in the first place.

What are the health consequences?

The effects can be varied and severe, ranging from fatigue and bloating to heightened food allergies, protein damage, detoxification inhibition, and a weakened immune system.

Leaky Gut is associated with a wide range of chronic conditions, including allergies, obesity, diabetes, inflammatory bowel disease, skin conditions, and more.

Unfortunately, many of these symptoms are unrecognized, and many cases of increased intestinal permeability are undiagnosed.

So what next?

Healing Leaky Gut is a journey. Our Functional Medicine Team will work with you to help identify and treat your specific underlying causes, and put you on a nutritional & lifestyle plan to optimal health & wellness.
