Exploring the Role of the Gut Microbiome in Skin Health (Part Two)

Written by Kiera Nikolakakis

Interprofessional Practice & Providing a Holistic Approach

A skin condition is usually just the surface/visible evidence of an internal health issue.

With inflammatory skin conditions like atopic dermatitis and acne vulgaris, which are commonly seen within our scope of practice, we are able to create patient care plans to help manage the condition.

However, more and more research suggests that where skin inflammation has risen there is potentially also gut inflammation. This could be due to an imbalance between the good and bad bacteria in the gut and can either be a mixture of a normal amount of good bacteria, but an over abundance of harmful bacteria, or not enough good bacteria and a normal to high amount of harmful bacteria.

The following is an analogy we can use to make it easier to help our patients understand that it is more than just what is showing on the surface of their skin:

“When it comes to gut dysbiosis and inflammatory skin conditions, think about how bees make honey. The gut is like the bee. The bee needs the right nutrients from the pollen in order to make honey. Similarly, the gut needs to have a nutrient and bacterial balance for the skin to perform its functions properly.”

It is always important to remember that this research is in its infantile stages, and the exact mechanisms of the gut microbiota's influence on various inflammatory skin conditions are yet to be entirely and comprehensively understood.

Looking after the gut can assist our patients in achieving the most desirable results from our clinical treatments and prescribed home care routine. Dermal Clinicians are highly trained and experienced in treating the external manifestation of inflammatory skin conditions, however, it is vital that we educate our clients on internal health, including root-causes of a condition and the benefits of practising a holistic approach when treating the skin.

We want our patients to understand how lifestyle factors and diet have the potential to both negatively and positively impact skin health and conditions. It is therefore important that we are able to educate our patients on why we are recommending they see other healthcare professionals, and how this will assist in further determining and fixing the root cause of their skin conditions.

Implementing inter-professional collaboration and respecting other healthcare providers’ perspectives in healthcare can help improve the patient's outcome.

The treatment of inflammatory skin conditions is complex due to its multifaceted nature. Dermal Clinicians can go as far as educating patients on how the diet can impact the skin, and what the gut-skin axis is. We can provide our patients with information on how the results of our clinical treatments and home care regimes can be enhanced by treating the underlying causes of a condition by referring to additional yet complementary healthcare professionals in which the gastrointestinal tract and dietary nutrition are within the scope of practice. This includes such healthcare professionals like a:

● Gastroenterologist

● Dietician

● Nutritionist

● Naturopath

Generalised and Common Suggestions for Balancing the Gut Microbiome

It is now understood that there are some lifestyle and nutritional factors which ultimately affect the gut microbiome. The following are some generalised and common themes that have arisen from these published studies:


Recent studies have actually shown that poor sleep quality or fragmented sleep correlates with poor microbiome diversity. In contrast, good sleep patterns are positively associated with a healthy, diverse gut microbiome.


Inappropriate or overuse of antibiotics can significantly affect the gut microbiome, causing changes in the

gut microbiota composition and leading to gut dysbiosis. This can be by causing an overgrowth of harmful

bacteria or can lead to antibiotic-resistant bacteria and therefore the spread of these bad bacteria.


Put extremely simply, there are foods that support a healthy gut microbiome and foods that can lead to (or contribute to) gut dysbiosis when consumed in mass abundance.

An example of food ingredients that support a healthy gut microbiome is prebiotics & probiotics. I’m sure we have all heard of prebiotics and probiotics by now – but what do they actually do?

Prebiotic-rich ingredients include (but are not limited to) legumes, whole grains, garlic and onion, which ultimately serve as food for probiotics. Probiotics naturally contain good bacteria, in which they possess multiple ways of keeping the body healthy, like aiding in removal of excessive bad bacteria to aid in balancing and re-establishing the gut microbiome colonisation.

On the other hand, a diet rich in refined carbohydrates has been shown to have an effect on the gut microbiome, being a contributing factor in gut dysbiosis. This includes foods and ingredients such as white bread, sugar, white pasta, and white rice.

The above are just a few of the many complex factors involved in gut dysbiosis. These are just some examples to help our clients understand and make their own connections to what might be causing their skin inflammation whilst seeking the appropriate advice and care.
