The gut-brain connection is so powerful in your immune health, hormonal health, and nervous system. If you’ve ever had a gut feeling then you know exactly what the gut-brain connection is.
The gut-brain connection is bi-directional communication between the gut and the brain. The gut, meaning our second nervous system or our enteric nervous system, and our brain, our first nervous system. This bi-directional communication happens through multiple pathways, including hormonal, immune, and our nervous system. The objective of the gut-brain connection is to maintain normal gut function, as well as appropriate behavior.
The first brain has 100 billion neurons, and our second brain, our gut has about 500 million neurons. You can see how powerful this neural connection is, and this neural connection happens primarily through the vagus nerve.
The vagus nerve originates in the brainstem and then wanders down to the gut. It signals in both directions. For example, if you are getting anxious about a presentation that you have to give you might feel that in your stomach, but if you are eating some kind of inflammatory foods, then that can cause you to potentially feel anxious.
Now, the next connection is hormonal, and this is based on the neurotransmitters or the chemical messengers that we have that communicate between the gut and the brain. Ninety percent of our serotonin is located in the gut that is produced by gut bacteria. Serotonin provides us with a sense of happiness. We also produce 50 percent of our dopamine, our feel-good hormone, in our gut. Another hormone we produce is called GABA (Gamma-aminobutyric acid), which decreases feelings of stress and anxiety.
Last but not least, our gut-brain is connected via immune pathways. Seventy percent of our immune system is in our gut. So, when we have any kind of gut issue, we typically have an immune or inflammatory issue. In the case of a leaky gut, for example, when you begin to have pathogens and toxins that are crossing the epithelial lining and moving into the bloodstream, this is going to cause an immune reaction. If this continues, this can cause a leaky brain because those pathogens and potentially undigested food can cross the blood-brain barrier causing inflammation in the brain feeling things like brain fog. So, as you can see there is a very strong immune system connection as well.
You may be asking, what can I do to optimize my gut-brain connection? The first thing you can do is try to eat an anti-inflammatory diet, which simply means whole food, natural, clean diet. Make sure that there are lean proteins, healthy fats, and lots of vegetables and fruits. If you are experiencing any specific gut or health issues, please make sure to reach out to us we’d be more than happy to help you. We can see you virtually or in person.
The next thing is to manage stress. Stress is one of the biggest things that can impact the gut-brain connection on both levels. You can help to decrease your stress through mindfulness, meditation, breathwork, yoga, journaling, reading, or whatever is helpful for you, perhaps even speaking with someone.
Next, is making sure you’re getting enough sleep. Also, make sure that you’re getting an optimal amount of sleep as well as quality sleep.
Lastly is movement. Instead of thinking of exercising 30 minutes a day, try to just move as frequently as you can throughout the day. This will help to optimize your immune system, nervous system, as well as your hormonal system by getting in regular quality movement.
I hope this helps you become more successful and achieve what you want in your life and your health.
