Can Leaky Gut Cause Anxiety? A Closer Look at the Connection

Leaky gut, also known as increased intestinal permeability, is a condition in which the lining of the small intestine becomes damaged, allowing bacteria and toxins to leak through into the bloodstream. This can lead to a variety of symptoms, including digestive issues, food sensitivities, and nutrient deficiencies.

The Link Between Leaky Gut and Anxiety

But can leaky gut also cause anxiety? There is evidence to suggest that there may be a connection between the two. The gut and the brain are connected through the gut-brain axis, a system that allows for communication and coordination between the two.

Research has shown that the bacteria in the gut, known as the microbiome, can influence the production of neurotransmitters such as serotonin and dopamine, which play a role in mood and emotion. An imbalanced microbiome, caused by leaky gut, may lead to an imbalance in neurotransmitter production, potentially contributing to the development of anxiety.

In addition, leaky gut has been linked to inflammation, which has been shown to play a role in the development of anxiety and other mental health disorders. The immune system and the nervous system are closely connected, and when the body is in a state of chronic inflammation, it can affect brain function and contribute to the development of anxiety and other mental health issues.

Treating Leaky Gut to Reduce Anxiety

So, can treating leaky gut help to reduce anxiety? It’s possible. By addressing the root cause of leaky gut and repairing the damaged lining of the intestine, it may be possible to improve the balance of the microbiome and reduce inflammation, leading to a reduction in anxiety symptoms.

There are several ways to treat leaky gut, including:

  • Following a leaky gut diet: This may involve eliminating certain foods that can irritate the gut lining, such as processed foods, alcohol, and caffeine, and incorporating foods that are rich in nutrients and supportive of gut health, such as fermented foods and bone broth.
  • Taking supplements: Certain supplements, such as L-glutamine and probiotics, may help to repair the gut lining and support the growth of beneficial bacteria in the microbiome.
  • Reducing stress: Chronic stress can contribute to leaky gut and worsen anxiety symptoms. Engaging in stress-reducing activities, such as meditation, yoga, or exercise, can help to improve both gut and mental health.

It’s important to note that while treating leaky gut may help to reduce anxiety, it’s not a guarantee. It’s also important to work with a healthcare professional to properly diagnose and treat leaky gut and any underlying conditions that may be contributing to anxiety.

It’s also worth noting that anxiety can be caused by a variety of factors, including genetics, life events, and imbalanced neurotransmitters. So, while treating leaky gut may be a helpful component of an anxiety treatment plan, it’s not a one-size-fits-all solution.


In summary, the evidence suggests that there may be a connection between leaky gut and anxiety. By treating leaky gut and addressing the root cause of the condition, it may be possible to improve the balance of the microbiome, reduce inflammation, and potentially reduce anxiety symptoms.
