You Have a Second Brain in Your Gut - Day 7

The Amazing Power of Your Second Brain - Your Gut!

That “gut feeling” is more than just a feeling. 

Your gut is quite the powerhouse! It has even got more neurons than your entire spinal cord. That's why it's often called our “second brain." And yes, we're talking about inside that very same belly of yours – there’s a complex network of nerves working hard to keep things running smoothly in there. But don't forget - if you let those bacteria go out-of-whack, they might be sending confusing messages straight up to your brain as well!

Your gut has its own nervous system, called the enteric nervous system (ENS), and it sends signals that affect both physical and mental health. This connection between the gut and the brain is known as the ‘gut-brain axis’.

It works both ways...

Not only can a poorly functioning gut affect your mood, but a change in mood or stress can also have an effect on you gut. For instance, when you feel anxious or stressed, it can cause changes to stomach acid production, bowel movements, and other factors that contribute to digestive symptoms such as vomiting, constipation or diarrhea.

The ENS also produces neurotransmitters like serotonin, dopamine and GABA which are responsible for regulating our emotions; these neurotransmitters help keep us feeling relaxed and happy. Interestingly, research suggests that up to 90% of serotonin – a neurotransmitter associated with feelings of happiness – is produced in the gastrointestinal tract! This explains why an imbalance in our gut microbiome (the bacteria in our intestines) can lead to changes in our moods; an unbalanced microbiome has been linked with depression and anxiety.

In addition to this there is evidence that inflammation present in certain gastrointestinal disorders such as IBS (Irritable Bowel Syndrome) may be linked to low levels of certain chemicals related to anxiety and depression.

Studies have also shown that probiotics may help improve symptoms of anxiety by promoting a healthier balance of bacteria in the intestinal tract, possibly due to their ability to reduce inflammation.

Overall, this research highlights just how significant the mind-gut connection is: what happens in one area directly affects the other, so if you want optimal mental health then taking care of your gut should be a priority!
