10 Signs of an Unhealthy Gut

The human body is home to trillions of microorganisms, including bacteria, viruses, and fungi, collectively known as the microbiome. While certain bacteria can contribute to diseases, many others play extremely important roles in maintaining immune function, heart health, weight regulation, and other aspects of your overall wellbeing. 

That said, an unhealthy gut can manifest in various ways, from digestive issues to seemingly unrelated symptoms. 

Learn the 10 signs of an unhealthy gut below so that you can take proactive steps towards restoring balance and vitality. 

Why is it so important to look after your gut?

The gut, also known as the gastrointestinal tract, is a complex system that not only aids digestion but also plays a crucial role in immune function, nutrient absorption, and even mental health. When the gut microbiome is out of balance, it can lead to a wide range of issues that extend far beyond digestive problems. 

An unhealthy gut can lead to digestive disorders like IBS, inflammatory diseases, and may even contribute to mental health problems such as anxiety and depression. This is because the gut houses trillions of bacteria that form the microbiome, which influences the immune system, nutrient absorption, and even the production of neurotransmitters like serotonin.

What are the top 10 signs of an unhealthy gut?

While an unhealthy gut can manifest in numerous ways, there are several common signs that should not be ignored. Here are the top 10 indicators that your gut health may need some attention:

1. Frequent digestive issues

Frequent digestive issues such as constipation, diarrhoea, gas, or bloating are key indicators of an unhealthy gut. These symptoms suggest that the digestive system is not functioning optimally, often due to insufficient fibre intake, or chronic stress. However, these symptoms may also indicate an imbalance in the gut microbiome, inflammation, or a disruption in the digestive process. Chronic constipation can be caused by poor gut motility, while diarrhoea may be the result of harmful bacteria or a food intolerance. Excessive gas and bloating can also point to an imbalance in the gut bacteria or difficulty breaking down certain foods.

2. Sleep disorders

Inflammation in the gut can disrupt sleep patterns and lead to restless nights. Additionally, people with gut imbalances may find themselves feeling tired during the day or struggling to wake up in the morning.

Poor gut health can contribute to sleep disorders, including insomnia, difficulty falling asleep, excessive daytime fatigue, and trouble waking up. This is because the gut and brain are closely connected through the gut-brain axis, and an imbalance in gut bacteria can impact the production of neurotransmitters like serotonin and melatonin, which regulate sleep cycles. 

3. Regular bouts of heartburn

Regular bouts of heartburn are often another sign of an unhealthy gut. This condition occurs when stomach acid flows back into the oesophagus, causing a burning sensation in the chest or throat. While occasional heartburn is common, persistent episodes may indicate an underlying issue such as an imbalance in gut bacteria, low stomach acid production, or a hiatal hernia. Factors such as a poor diet, stress, and overuse of medications can also disrupt the gut's balance, leading to chronic heartburn.

4. Food intolerances

Developing sensitivities or intolerances to certain foods can be a red flag for gut health issues. When the gut is imbalanced or inflamed, it may struggle to break down and absorb certain nutrients properly, leading to adverse reactions. The most common food intolerances include lactose intolerance, gluten sensitivity, or intolerances to specific proteins like those found in nuts or soy. These intolerances can cause symptoms like bloating, diarrhoea, abdominal pain, and even skin rashes, indicating that the gut is struggling to process these foods efficiently.

5. Rapid weight gain or loss

Unexplained and rapid weight changes can be linked to an unhealthy gut. Of course, the gut plays a vital role in nutrient absorption, so an imbalance in gut bacteria can impact how effectively your body processes and utilises the nutrients from food. For instance, chronic inflammation in the gut can disrupt hormones that regulate appetite and metabolism, leading to either unintended weight gain or weight loss. Certain gut imbalances may also contribute to increased cravings for unhealthy foods, further exacerbating weight fluctuations. 

6. Regular acne breakouts

Unsurprisingly, regular acne breakouts can be linked to an unhealthy gut. This is due to the fact that the gut microbiome influences inflammation levels throughout the body, including the skin. In turn, an imbalanced gut can lead to increased systemic inflammation, which may manifest as acne and other skin issues. Additionally, poor gut health can affect hormone production, further exacerbating the acne breakout. As well as this, consuming a diet high in processed foods and sugars can disrupt gut balance and contribute to skin problems. 

7. Brain fog

Brain fog, characterised by confusion, forgetfulness, and lack of focus, can be a symptom of an unhealthy gut. The gut-brain connection, mediated by the vagus nerve and various biochemical signalling pathways, means that gut imbalances can directly affect cognitive function. Poor gut health can lead to inflammation and disrupt the production of neurotransmitters like serotonin and dopamine, which are crucial for mental clarity and focus. Additionally, as mentioned before, an unhealthy gut can affect how the body absorbs nutrients  leading to possible deficiencies in essential vitamins and minerals necessary for optimal brain function.

8. Mood swings, anxiety and depression

The gut is often referred to as the "second brain" due to the presence of millions of nerve cells and the production of neurotransmitters like serotonin, which regulate mood and emotions. An imbalanced gut microbiome can disrupt serotonin production, leading to mood disorders. More specifically, gut inflammation can trigger the release of pro-inflammatory cytokines, which are associated with increased anxiety and depression. Additionally, an unhealthy gut can impair the absorption of essential nutrients like vitamin D, omega-3 fatty acids, and magnesium, which are important for mental wellbeing. 

9. Frequent migraines

The gut-brain axis plays a significant role in neurological health, and an imbalanced gut microbiome can contribute to migraine triggers. Poor gut health can lead to systemic inflammation and increased production of certain chemicals, such as nitric oxide, which can trigger migraine. As well as this, nutrient deficiencies caused by poor gut absorption can exacerbate migraine frequency and severity. 

10. Autoimmune disorders and inflammation

An unhealthy gut has been closely linked to autoimmune disorders and chronic inflammation. The gut barrier, when compromised, can allow harmful substances to leak into the bloodstream, triggering an immune response. This condition, known as "leaky gut," can lead to chronic inflammation and the development of autoimmune conditions, where the immune system mistakenly attacks the body's own tissues, leading to inflammation and tissue damage. 

Factors like poor diet, stress, and antibiotic overuse can disrupt gut health and exacerbate these issues.

What can cause an unhealthy gut?

An unhealthy gut is often the result of an imbalanced microbiome, which refers to the trillions of microorganisms residing in the gastrointestinal tract. This imbalance, known as dysbiosis, can be caused by various factors that disrupt the delicate balance of beneficial and harmful bacteria.

One major contributor to an unhealthy gut is a poor diet high in processed foods, refined sugars, and unhealthy fats. These dietary choices can feed harmful bacteria while starving the beneficial ones, leading to an overgrowth of potentially harmful microbes. Chronic stress can also wreak havoc on the gut microbiome by compromising the integrity of the gut lining and altering the gut's immune response.

Frequent antibiotic use is another culprit, as these medications can indiscriminately kill off both harmful and beneficial bacteria, leaving the gut microbiome in disarray. Certain medications, such as birth control pills and non-steroidal anti-inflammatory drugs (NSAIDs), can also disrupt the gut microbiome by altering its composition.

Environmental factors like exposure to toxins, pollutants, and chemicals found in household products or personal care items can also contribute to an unhealthy gut by disrupting the delicate balance of microorganisms. Additionally, lifestyle factors such as lack of physical activity, poor sleep habits, and high levels of stress can all negatively impact the gut microbiome.

By being aware of the signs of an unhealthy gut and addressing the underlying causes, you can take proactive steps towards restoring balance to your microbiome. This may involve dietary changes, managing stress levels, and minimising exposure to disruptive factors like antibiotics and environmental toxins. Additionally, incorporating gut-friendly probiotics and postbiotics can support a diverse and thriving gut microbiome.
