Which Health Conditions Can Be Linked to Your Gut Health?
21 August 2025

In this article, we will explore the intricate connection between your gut health and overall well-being. We look at the pivotal role gut bacteria play in maintaining your health and examine how imbalances in your gut microbiome can impact various bodily functions. From digestive disorders to mental health conditions, we will explain how the health conditions you face can be influenced by the delicate ecosystem within your gut.
Key Takeaways
Here are the key takeaways from this article about health conditions and gut health:
Gut bacteria influence emotions and brain function.
The gut microbiome is connected to gastrointestinal conditions such as diarrhoea and irritable bowel syndrome (IBS).
Lactose intolerance can be affected by the composition of gut bacteria.
Imbalances in the gut microbiome are linked to insulin resistance and may contribute to the onset of type 2 diabetes.
Disruptions to the gut microbiome can contribute to metabolic dysfunction and inflammation associated with obesity.
The composition of gut microbiota may influence blood pressure regulation.
Imbalances in gut microbiota can impact skin health, potentially leading to inflammatory skin disorders such as eczema, psoriasis, and acne.
Does gut bacteria play an important role in the body?
Yes, the bacteria in your gut can have a significant influence within the body. Just as your brain sends messages throughout your body, research suggests that your gut communicates back. Studies indicate that the balance of bacteria in the gut microbiome can impact emotions and the brain's processing of sensory information including sights, sounds, flavours, and textures [1]. This suggests that alterations in the balance of this microbiome might contribute to conditions such as autism, anxiety, depression, and even chronic pain.
Below are some of the conditions that researchers suggest could be affected by the balance of bacteria in your gut microbiome.
Diarrhoea
The gut microbiome can significantly influence the risk of having diarrhoea. While common causes of this condition include infections, food allergies, food poisoning, and medication side effects, new research has highlighted the role of gut bacteria in diarrhoea onset and severity. Disruptions to the balance of bacteria in the gut microbiome due to medications or dietary factors can contribute to diarrhoea. Managing diarrhoea typically involves staying hydrated and adjusting your diet. Emphasising good hygiene, proper food storage, and cautious food and drink consumption can also help in preventing diarrhoea [2].
IBS
The gut microbiome can play a crucial role in Irritable Bowel Syndrome (IBS) [3]. Alterations in the composition and function of the gut microbiome may contribute to the development and exacerbation of IBS symptoms. Factors such as diet, stress, medications, and an imbalance in gut bacteria can all impact the severity of IBS symptoms. Addressing microbial imbalances through dietary modifications and other therapeutic interventions can help you to manage IBS symptoms and improve overall gut health.
Lactose intolerance
The gut microbiome also plays an important role in lactose intolerance [4]. Lactose intolerance occurs due to the body's inability to fully digest lactose, a sugar found in dairy products, due to insufficient levels of the enzyme lactase. The composition of bacteria in the gut microbiome can influence the digestion of lactose. In people with lactose intolerance, certain bacteria in the gut ferment lactose which can lead to symptoms such as bloating, gas, and diarrhoea. Maintaining a healthy balance of gut bacteria is crucial for managing lactose intolerance and mitigating its symptoms.
Diabetes
The molecules and chemical messengers produced by the gut microbiome can influence insulin sensitivity and glucose metabolism, which can have an impact on diabetes. Imbalances in the gut microbiome composition have been linked to insulin resistance, which can ultimately contribute to the onset of type 2 diabetes. Understanding and nurturing the balance of bacteria in the gut may help in managing and preventing diabetes [5].
Obesity
Disruptions to the gut microbiome can lead to a compromised gut barrier. This can result in a ‘leaky’ gut, where bacterial fragments are released into the bloodstream. These fragments can then work through the body to different tissues, potentially contributing to inflammation and metabolic dysfunction which is associated with obesity [6].
Hypertension (high blood pressure)
Several studies have revealed a connection between the composition of gut microbiota and conditions such as atherosclerosis, heart attacks, and high blood pressure. The balance of bacteria in the gut may play a role in regulating blood pressure levels. Targeted dietary changes that can modulate gut microbiota can potentially lower the risk of hypertension and related cardiovascular conditions [7].
Skin
An imbalance in gut microbiota can have an effect on the condition of the skin. This imbalance can disrupt immune function and trigger inflammation which can compromise the skin and contribute to inflammatory skin disorders such as eczema, psoriasis, and acne. Addressing gut bacteria imbalances through diet and lifestyle interventions can help to prevent or treat certain skin conditions [8].
Final Thoughts
The health of your gut microbiome plays a crucial role in maintaining overall well-being, influencing various bodily functions far beyond digestion. From regulating emotions and brain function to impacting conditions such as IBS, diabetes and obesity, the balance of gut bacteria is vital to your health. Disruptions in the microbiome can lead to a range of health issues, including gastrointestinal disorders, skin conditions and even metabolic imbalances. By understanding the importance of gut health and taking steps to nurture it, such as through diet and lifestyle changes, you can support your body in preventing and managing these conditions.
