Hippocrates once said “all disease begins in the gut” and, even though as a naturopathic doctor I have internalized this to the utmost degree, I still forget from time to time. 

So, when I was having an increase in histamine symptoms (itchy eyes, runny nose, inflammation, congestion, itchy skin, immune issues), dental issues (bad breath, swollen tongue, increase in plaque and bleeding gums), gut issues (bloating, constipation, sugar cravings) and mood issues (PMS, low motivation, fatigue, brain fog, lower mood, fatigue) as well as other random symptoms such as decreased stamina, cold intolerance and otherwise just feeling “blah”, it took me an embarrassingly long amount of time to connect all these symptoms to being caused by a gut microbial imbalance. 

Our gut bacteria outnumber the cells of our body by 10 to 1. These little guys influence our digestion, mood and immune system. They affect our brain function. A recent study in Frontiers in Psychiatry (Nguyen et al., 2021) even connects the diversity of our microbiome with loneliness and wisdom. 

Interestingly, loneliness and wisdom have been found to occur in inverse relationship with one another. In other words, the wiser you are, the less lonely. It’s important to note here that loneliness is not the same thing with isolation or being alone–sometimes alone time is necessary for the type of self-reflection that imbues wisdom. 

Wisdom is a complex phenomenon that is made up of traits like compassion towards self and others, self-awareness and reflective thinking and deep knowledge about the world and the meaning of life events. From this description we can imagine how protective wisdom might be against mental illness and how it may lend to mental, emotional and physical wellness.

The wiser you are, the better able you may be to make meaning of and persevere through life’s difficulties and connect with others. Wisdom lends itself to an overarching view of self, life and humanity that may allow us to respond to life’s challenges with resilience. 

Perhaps a wise person who is alone may also be aware that they are also part of an interconnected ecosystem that includes self and others. They may be aware of their place within the fabric of existence. In this way, they are never really alone.

Further, the meaning they may derive from states of aloneness may protect them against the feelings of social isolation that are characterized by loneliness. Imagine a wise figure. Perhaps they are alone, but would you say they are lonely? 

Our gut is sometimes called “the second brain” and forms part of the microbiota-gut-brain axis in which our gut bugs influence the health of our intestines and thus influence our nervous system, immune system and brain (Cryan & Dinan, 2012). Our gut microbiome can even influence personality traits such as agreeableness, openness and even neuroticisim (Kim et al,m 2018). Interestingly, unhealthy gut bacteria like proteobacteria (associated with SIBO) were associated with low conscientiousness and high neuroticisim (Kim et al., 2018).

Does this mean that diet can influence our tendency to hand things in on time and keep our rooms clean? hmm… 

It’s interesting to think that we all have a sense of our personalities and who we are as people. We imagine ourselves to be introverted or extraverted, artistic, creative, liberal or conversative. We might consider ourselves kind or trustworthy, blunt or afraid of conflict. We may identify as people who make healthy eating choices and enjoy exercising or who have sweet tooths (teeth?).

Amidst this self-discovery, the exploration of mbti personalities seamlessly weaves into the fabric of our understanding, adding another layer to the rich and diverse mosaic of human characteristics. Delving into the realm of MBTI personalities opens a door to a nuanced comprehension of ourselves and those around us. The Myers-Briggs Type Indicator, with its sixteen distinctive personality types, provides a structured framework to decipher the intricacies of our individuality. This insightful exploration not only enhances self-awareness but also fosters a greater appreciation for the diverse ways in which personalities interlace and contribute to the vibrant mosaic of the human experience.

But what if we are less in control of our behaviour and even personality than we think? The truth is the bacteria in our gut produce chemicals that influence our behaviour: what we crave and eat and even how we act and think. In turn, this influences the composition of our gut. 

Prosocial behaviour is associated with more gut biodiversity, and people who are more social tend to have microbiomes that are more diverse (Johnson, 2020). This makes sense if you think about it. If you’re exposed to a variety of people and environments, you’re likely exposed to a variety of bacteria and viruses as well. These microbes are ingested and incorporate themselves into our bodies.

When we visit different environments we consume foods in those environments. When we socialize with various people, we often share food. This increase in food diversity will also influence gut microbial diversity. 

As I write this, I wonder about the effects of social isolation of the past 2-3 years. During Covid, our social circles decreased. Currently we are seeing a rise in infections: colds, flus and other illnesses (RSV, hand food and mouth disease, pink eye and so on), particularly in children. I wonder if this lack of socialization has affected our microbiomes and thus our individual and collective immunity. A hypothesis worth exploring, perhaps… 

Further, the hypersanitization may also have contributed to shifting the health of our microbiome. It still remains to be seen. 

We know that a lack of gut diversity can affect our immune system and is associated with obesity, inflammatory bowel disease and major depressive disorder (Jiang et al., 2015). In mice, the health of the microbiome is essential for their social development (Desbonnet et al., 2014)! 

So, what does this mean practically and clinically? 

Throughout my studies and years practicing as a naturopathic doctor, a clear-cut path towards improving microbiobial health of the gut is still unclear to me. We know that increasing the amounts of plants and fibre in the diet can support gut diversity. But we also know that fibre can cause constipation and bloating in some individuals and aggravate their digestion and that there are many indiviudals who at least anecdotally seem to thrive on diets that reduce fibre, such as the Carnivore Diet or an Animal-Based Diet (which, by the way, I’m not necessarily recommending here). 

For me, gut health has largely been about paying attention and noticing when things have gone astray and then (and this part is harder than it sounds) correctly attributing what has gone astray to a shift in the health of my microbiome. 

This has been years in the making. Our gut produces pain in response to stretch (i.e.: from gases in the intestines). We don’t necessarily feel pain in our gut if we’re experiencing intestinal permeabilty (leaky gut) or dysbiosis. This means that there is not a lot of feedback from our body that tells us about the state of our gut. Our gut doesn’t always hurt if it’s inflamed or imbalanced in the way your shoulder might. We need to look for other signs and symptoms that alert us to the state of health of our guts. 

For me symptoms of gut imbalance often correlate with symptoms of candida overgrowth (something I, like many, am prone to). Candida, a species of yeast, tends to flourish in my body if my overall gut ecosystem is failing to keep it in check. Sometimes this can occur due to stress, and increase of sugar in my diet and other factors. 

Symptoms I notice are:

– A change in oral health: more plaque on my teeth, bad breath, tongue coating, bleeding gums, and so on. 
– A change in mood and mental functioning: symptoms of depression or dysthymia such as apathy, low motivation and lethargy. Brain fog, difficulty concentration, poorer executive function (particularly initiating tasks or increased procrastination). 
– A change in digestion: persistent bloating, more constipation (involving not just frequency but stool quality. They might be stickier or harder to pass). 
– A change in immune function: more mucus production and congestion. Allergy symptoms. Trouble breathing,. 
– A change in energy and metabolism: reduced stamina despite exercising. Weight gain. Water retention. Fatigue. Feeling cold. 
– A change in cravings: wanting more sugar, binge-eating and overeating. Obsessing about food. Cravings for sugar after meals. Feeling “hangry” more often. Difficulty feeling full. Mental hunger (hunger despite feeling the presence of food in the stomach).  
– A change in hormonal health: changes to libido, vaginal flora. heavier periods, irregular periods. Increased PMS. 

And so on. If this seems like virtually every system in the body is affected, I remind us all that Hippocrates said it first (or at least most famously): “all disease begins in the gut”. 

What is the solution? Like recognizing the cause, the solution is often subtle. For me it was focusing attention to gut health and slowly steering the ship back to healthier habits.

The problem with dysbiosis is it often maintains itself. Low energy leads to less socialization and less motivation to cook healthy meals. More cravings lends to poorer food choices. These are just some examples of what you can imagine to be a variety of maintenance processes that are caused by and serve to perpetuate dysbiosis.

Therefore for me, the solution is not to make drastic changes but to identify and shift these patterns in support my microbiome. 

1) I took sugar out of my diet. For me this involved shifting away from my 3 fruits a day to starchy vegetables (like squashes, etc.) I thrive on a Paleo-like diet (a whole foods diet that emphasizes fruit, vegetables and animal protein) and subtly shifted back to one.

I didn’t completely eliminate fruit sugar as I don’t believe there is a need. However, I recognized that I was likely overconsuming sweet foods as a response to dysbiosis and this wasn’t serving me. 

2) I got on a comprehensive and broad-spectrum probiotic. I often tell my patients that probiotic prescribing is more of an art than a science and involves some trial-and-error. I typically look for one that has 8+ strains and a high CFU (colony forming unit) count. I took Colon Care 90 Billion by New Roots. This is certainly not the only good one and it might not be the right one for you, but it’s one I selected for myself based on a variety of factors I was looking for that supported my individualized assessment of my gut health. 

For me probiotics can be highly effective, but they take time to work. They often can aggravate symptoms initially. The first symptoms I notice that indicate improvement are an improvement in oral health. 

3) I supported my digestion in general. This involves for me supporting the liver and gallbladder, which influence gut motility, bile flow (which helps keep the small bowel free of bacteria) and fat digestion (which prevents growth of more pathogenic microbes and stabilizes blood sugar). 

4) I consumed anti-candida, antimicrobial foods that work for me (again, this is after much trial and error). Raw garlic, coconut oil, apple cider vinegar and oregano oil. I also started on a candida herbal supplement that incorporates cloves, black walnut and other anti-microbial herbs that selectively kill pathogenic microbes while typically preserving healthy ones. 

5) I supported my microbiome by integrated back into nature: getting outside more, reducing chemical exposure (soaps, fragrances, plastics, pesticides, etc.) and getting more sunlight. Camping outside in the cold, sleeping on the ground and brushing my teeth in a natural brook in Nova Scotia also likely contributed to shifting the diversity of my microbiome through encouraging the exchange of my microbes with those of the earth. 

6) I supported the body’s stress response by getting more sleep. When I’m awake I try to get as much sun exposure as possible. Our microbiome and our Circadian Rhythms are intricately connected. Supporting one can support the health of the other (Bishehsari et al., 2020). Regarding this, I wonder if Daylight Savings Time made some of us more susceptible for microbial imbalances in our guts? Hm… 

Getting off track is a holistic multi-facted process. We all know our own vices and susceptibilities if we look deep enough. 

Therefore, getting on track is an equally holisitic and comprehensive process. It involves wisdom (which, conveniently, increases as your microbial health increases). I can help you figure things out if you’re new to this process. 

After implementing these strategies and paying a bit more attention for a few weeks I slowly and surely notice myself feeling more like myself. Getting back on track: more energy, better mood, better cold tolerance (this is a big one!) and better gut health. My appetite has regulated incredibly. I feel like a different person. But the shifts have been slow and sometimes subtle (as is often the case with shifting an entire ecosystem) and paying attention to them is a very important part of the process. 

Wisdom. 

It’s not just diet. It’s not just supplements. It involves looking at the relevant factors and gently moving back in the right direction with patience and persistence. Maybe your main point of focus needs to be eating regular meals and meal planning. Maybe you need more strength-training. Maybe you need to start socializing more, getting out in public (knitting circle, anyone? I’ve been hearing so much about knitting circles these days, haha–a sign from the universe?). 

Maybe it’s time to look at emotional eating with a pair of fresh eyes (perhaps through the lens of your microbiota). Maybe you need to take a walk outside today. Everyday. Breathe fresh air. Take a probiotic.
