Our global mental health crisis is growing at an exponential rate, with over half a billion people suffering from depression and anxiety; it’s time we rethink our understanding of the underlying root causes of mental health challenges.

From treating thousands of patients, I’ve learned that depression is not in your head. It’s in your body. More specifically, your gut. When your gut is unhealthy and inflamed, your brain is unhealthy and inflamed. In Functional Medicine, we know that the gut and the brain are intimately connected and that the health of one directly influences the health of the other.

In today’s Health Bites episode, we’re diving into the gut-brain connection and sharing Functional Medicine tools to support your gut health and, as a result, your mood and mental health.

In this episode, I discuss:

Our global mental health crisis (2:45)
The gut-brain connection (4:18)
The story of Marks's broken brain (5:15)
Features of the gut-brain axis (8:57)
Gut hormones that send signals to your brain (10:06)
Role of the gut microbiota in mood and mental health (12:24)
How stress negatively impacts our gut microbiome (20:14)
The link between leaky gut and poor mental health (21:41)
The Functional Medicine approach to fixing the gut (25:56)
The 5R Program for fixing your gut health (30:09)

Address inflammation to combat depression as a body issue

Depression is often not a problem originating in your head, but rather a physical problem in your body driven by inflammation from sources like your gut.

Address gut inflammation to alleviate 'irritable brain' symptoms

Contrary to the belief that anxiety causes Irritable Bowel Syndrome (IBS), it is often the inflammation from an unhealthy gut that leads to an 'irritable brain'.

Recognize gut microbiome's role in blood metabolites

A third to a half of all the metabolites, or small molecules, circulating in your blood are not human but are produced by your gut microbiome.

Leverage Akkermansia for natural calming effects

The beneficial gut bacteria Akkermansia produces the neurotransmitter GABA, which has a calming effect on the brain and is described as a 'natural Valium'.

Address bad relationships to prevent leaky gut

A study on couples found that marital distress and hostile interactions were linked to higher levels of leaky gut and inflammation-causing bacterial toxins.
