And people with IBS or irritable bowel syndrome had three times higher risk of anxiety, two times greater risk of depression, and then two times greater risk of suicide ideation, meaning they were thinking of suicide versus the general population. Now we used to think that anxiety caused IBS. But now we know it's the other way around and a little bidirectional. So think about that.

It's not really the stress or anxiety or mental health issues that's causing irritable bowel. It's the change in the microbiome and the irritation, inflammation to the gut lining and the enteric nervous system that feeds back to the brain. It creates an irritable brain. So irritable bowel leads to an irritable brain. So before we dive any deeper, let's define the features of this gut-brain axis.

The gut, which basically we talked about, is the GI tract. It starts at your mouth and it goes to your anus. It includes esophagus, stomach, small intestine, large intestine, all the way down to the bottom. The vagus nerve is the longest nerve that comes from your brain called the cranial nerve.

It travels through the brainstem to the gut and it connects the gut to the central nervous system and it goes through the entire higher GI tract. Think about it. You've got huge amounts of gut. If you, if you laid out your small intestine flat, it would be the surface area of a tennis court. And then there's your large intestine and then your esophagus. So all that is really important.

The vagus nerve connects to other things like your heart and lungs and so forth. But this vagus nerve is a really important part of your nervous system called the parasympathetic nervous system. This is the relaxation nervous system. It also is called the autonomic nervous system or automatic nervous system.

So it's not usually under our willful control, although we can regulate it through various practices. The yogis have been doing this for centuries. It regulates involuntary sensory and motor functions. You say, I'm going to move my arms. You move your arm, but you'll go, oh, I want to digest my food. Can you please digest the food in there? Can you please regulate my heart rate?

Can you control my blood pressure? You don't really think about it. These things happen automatically. A lot of this happens through this automatic system. There's a lot of signaling that happens through this nervous system. For example, it helps control appetite. And how does it do that? Through a peptide hormone called GLP-1, right? You might've heard about this. This is...

Ozempic, Rigobi, and so forth. Manjaro, these are drugs now, quote drugs, but they're not really drugs. They're just mimicking your body's own GLP-1 at a much higher concentration. This is also known as the satiety hormone. I mean, it makes you feel full, which is why people don't eat because they take this shot and they don't feel full.
