Which health conditions can be linked to your gut health?

This article looks at the strong link between gut health and overall wellness. We’ll explain the essential part gut bacteria play in supporting your body and how disruptions in your gut microbiome may affect a wide range of functions. From digestive issues to mental health concerns, we’ll outline how your health can be shaped by the delicate balance of microorganisms living in your gut.

Key Takeaways

Here are the main points to understand about the connection between gut health and health conditions:

• Gut bacteria can affect mood and brain activity.

• The gut microbiome is linked to digestive problems such as diarrhoea and irritable bowel syndrome (IBS).

• The way your gut bacteria are made up can play a part in lactose intolerance.

• Disruptions in gut bacteria are associated with insulin resistance and may raise the risk of type 2 diabetes.

• Changes in gut bacteria can cause inflammation and metabolic problems linked to obesity.

• Gut microbiota may influence blood pressure levels.

• Imbalances in gut bacteria can contribute to skin conditions like eczema, acne and psoriasis.

How does gut bacteria influence your health?

Yes, gut bacteria have a major role in the body. Research shows that just as the brain sends signals to the rest of the body, the gut can send signals back. This two-way communication may affect emotions, mood and how the brain interprets sensory input such as taste, touch and sound [1]. Studies suggest that changes in the microbiome may be connected to conditions such as anxiety, depression, chronic pain and autism.

Below are some of the conditions thought to be linked to changes in gut bacteria.

Diarrhoea

Gut bacteria can influence both the risk and severity of diarrhoea. While it often results from infections, food poisoning, allergies, or certain medicines, research indicates that the gut microbiome plays an important role too. Medications or dietary changes can disrupt the bacterial balance and trigger diarrhoea. Treatment usually involves staying hydrated and adjusting food intake, while prevention relies on good hygiene, safe food storage and care with what you eat and drink [2].

IBS

The microbiome also plays a role in Irritable Bowel Syndrome (IBS) [3]. Shifts in the types and functions of gut bacteria may worsen IBS symptoms. Factors such as diet, stress, medicines and bacterial imbalances all affect flare-ups. Supporting a healthier microbial balance through dietary changes or treatments may help ease symptoms and improve gut function.

Lactose intolerance

Lactose intolerance happens when the body cannot digest lactose properly due to low levels of lactase, the enzyme that breaks it down [4]. Some bacteria in the gut can ferment lactose in people with this condition, causing bloating, gas and diarrhoea. A well-balanced microbiome can help manage symptoms and improve tolerance.

Diabetes

The gut microbiome produces substances that influence how the body responds to insulin and processes glucose. When the microbiome is out of balance, it can contribute to insulin resistance, which increases the likelihood of type 2 diabetes [5]. Looking after gut health may be a useful approach to reducing risk and supporting diabetes management.

Obesity

An unhealthy microbiome can weaken the gut barrier, creating what is sometimes called a ‘leaky gut’. This allows bacterial fragments to enter the bloodstream and travel around the body, which can promote inflammation and metabolic problems linked to obesity [6].

Hypertension (high blood pressure)

Research has shown that gut bacteria may be connected to cardiovascular problems such as atherosclerosis, heart disease and high blood pressure. The balance of bacteria may influence how blood pressure is controlled, and dietary changes that support gut health may help lower the risk of hypertension and related conditions [7].

Skin health

The microbiome also has an impact on the skin. Disruptions in gut bacteria can affect the immune system and lead to inflammation, which may worsen conditions such as eczema, psoriasis and acne. Supporting gut health using diet and lifestyle may help prevent or ease skin flare-ups [8].

Final Thoughts

Your gut microbiome is key to maintaining good health, affecting much more than digestion alone. From mood and brain function to conditions like IBS, diabetes and obesity, a balanced gut supports your overall well-being. Disruptions in this balance can contribute to digestive problems, skin conditions and metabolic disorders. By recognising the importance of gut health and making changes to support it, such as through diet and lifestyle, you can take positive steps towards preventing and managing a wide range of health issues.
