Gut Check: How To Know If Your Gut Health Needs Attention

Are you on top of your gut health? Understanding the importance of a well-balanced gut is more than just managing stomach aches or avoiding indigestion. It’s about ensuring your overall health and wellness foundation is strong. Here’s why giving your gut the care it deserves can transform your life in ways you might not expect.

Your gut is a powerful, complex system often called the body’s second brain. It does much more than process the food you eat. It’s the cornerstone of your immune system, your mood regulator, and a key player in your overall wellbeing. When your gut is out of balance, it doesn’t just lead to discomfort; it can have far-reaching effects on your entire body and mind. A balanced gut microbiome is essential for optimal nutrient absorption. When your gut health isn’t up to par, you’ll never reap the benefits of eating nutrient-rich foods. It’s like putting premium fuel in a car that can’t be used effectively. And if you’re on a journey toward weight management, chronic disease prevention, or just wanting to be the best version of yourself that you can be, your gut health is a critical ally in this quest. But the benefits don’t stop there. Research has linked gut issues to skin conditions such as eczema and acne, suggesting that a glowing complexion might begin with your gut.

Your gut is vital in your quest for good health. If you’re experiencing subtle signs that your gut health might be off-kilter, it’s time to give it the attention it deserves. Stick with me as we explore the telltale signs of gut issues and what you can do to bring your gut back into balance. Because when your gut thrives, you thrive.



In functional medicine, we approach gut health with a holistic lens, understanding that a myriad of factors can contribute to an unhealthy gut. Identifying these factors is crucial to restoring balance and vitality to your gut.

Diet: The Foundation of Gut Health

At the forefront of gut health is diet. Consuming a diet high in processed foods, sugars, and unhealthy fats can wreak havoc on your gut microbiome, the collection of bacteria, fungi and viruses that call your gut home. These foods can promote the growth of harmful bacteria, leading to an imbalance known as dysbiosis. This imbalance is a primary culprit in gut inflammation, poor digestion, and digestive disorders. Conversely, a diet rich in whole foods, fibre, and fermented products supports a diverse and robust gut microbiota.

Stress: The Silent Gut Disruptor

Never underestimate the power of stress on your gut. When stressed, your body enters a ‘fight or flight’ mode, diverting energy away from digestion. This can lead to decreased nutrient absorption, imbalances in gut bacteria, and increased intestinal permeability – often called ‘leaky gut’. Managing stress is not just about mental health; it’s a critical component of digestive wellness.

Antibiotics and Medications: A Double-Edged Sword

While life-saving in many scenarios, antibiotics can significantly disrupt the gut microbiome. They kill not only harmful bacteria but also beneficial ones that are vital for gut health. Other medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin and acid-reducing drugs like omeprazole, can also contribute to gut dysbiosis and compromise the gut lining and vitamin absorption. 

Environmental Toxins: The Unseen Threat

We’re exposed to a plethora of environmental toxins, from pesticides in our food to pollutants in the air. These toxins can directly impact our gut health by altering the gut microbiome and damaging the gut lining, leading to increased inflammation and susceptibility to gut disorders.

Lifestyle Factors: More Than Just Food

A sedentary lifestyle, poor sleep patterns, and unhealthy eating habits can all contribute to poor gut health. Physical activity, good sleep hygiene, and mindful eating are pivotal in maintaining a healthy gut.


Understanding the signs and symptoms of an unhealthy gut is crucial, as it can guide us towards timely and effective interventions. Here are some of the key indicators that your gut might need attention:

Digestive Discomfort: The Obvious Culprit

The most straightforward signs are digestive issues such as bloating, gas, constipation, diarrhoea, pungent-smelling stool, and heartburn. These symptoms can be more than minor inconveniences; they’re your body’s way of signalling an imbalance in your gut microbiome or issues with digestive function.

Fatigue and Sleep Disturbances: More Than Just Tiredness

Feeling constantly tired, despite adequate sleep, can indicate an unhealthy gut. A compromised gut can impact the absorption of nutrients, which are vital for energy production. Furthermore, the gut produces a significant amount of serotonin, a critical neurotransmitter that influences sleep quality.

Unexplained Weight Changes: The Gut-Weight Connection

Unintended weight gain or loss without a change in diet or exercise habits can indicate gut health issues. An imbalanced gut microbiome can affect your body’s ability to absorb nutrients, regulate blood sugar, and store fat. Gut microbial populations have been shown to impact weight. Twin studies have shown differences in gut diversity between obese and lean twins. In addition, some studies have also demonstrated how gut microbes influence the production of hunger (ghrelin) and satiety (leptin) hormones.

In addition, irregular bowel movements will result in the accumulation of toxins, interfering with how well you feel and even your ability to lose weight.

Skin Irritation: The External Manifestation

Skin conditions like eczema, acne, or rosacea may be linked to an unhealthy gut. The gut-skin axis highlights how increased intestinal inflammation can leak certain proteins out of the gut, affecting skin health.

Mood Swings and Mental Health: The Gut-Brain Link

Emerging research underscores the gut-brain connection. Issues like anxiety, depression, and mood swings may correlate with an unhealthy gut. A balanced gut microbiome is essential for producing neurotransmitters and regulating hormonal balance.

Food Intolerances: A Red Flag

Difficulty digesting certain foods, especially those that haven’t previously been an issue, can be a symptom of poor gut health. Again, increased intestinal permeability will likely be implicated in developing sensitivities and intolerances. Another factor may be a lack of enzymes needed to digest the food.

Autoimmune Conditions: The Gut’s Defense Gone Awry

The immune system is directly connected to gut health and function. Everything you eat and swallow has been in contact with the outside world. Consequently, the gut-associated immune system is vital in ensuring that nothing that shouldn’t get in gets in and your gut-associated immune system is activated only when necessary and not overstimulated. Suppose your gut-associated immune system is constantly activated. In that case, it can lead to body-wide alertness, causing your immune cells to release messenger molecules that result in systemic inflammation, leading to immune system dysregulation and potentially contributing to autoimmune conditions.

Sugar Cravings: A Telltale Sign of an Imbalanced Gut

Sugar cravings are often more than just a matter of willpower; they can indicate an imbalanced gut. In functional medicine, we understand that cravings, especially for sugar, may be closely tied to the health of your gut microbiome.

1. Microbial Influence on Eating Habits: Certain microbes, like yeast (Candida) and parasites, thrive on sugar and processed foods. As a result, they may influence your cravings by releasing compounds that signal your brain to seek more sugary foods. This creates a cycle where sugar-loving microbes get fed, proliferate, and continue to amplify sugar cravings.

2. Blood Sugar Imbalances: An unhealthy gut can lead to poor blood sugar regulation and frequent spikes and dips. These fluctuations often manifest as sugar cravings, as your body seeks a quick source of energy to balance blood sugar levels.

3. Serotonin Production: Serotonin, a neurotransmitter that contributes to feelings of happiness and wellbeing, is predominantly produced in the gut. An unhealthy gut can compromise serotonin production, leading to mood swings and cravings for sugar as a temporary mood enhancer.

4. Nutrient Absorption Issues: If your gut is not functioning optimally, it can impair the absorption of nutrients. This malabsorption can lead to deficiencies that your body tries to compensate for by craving quick energy sources like sugar.
