Gut Feelings are valid
Have you ever experienced a "gut feeling" - that intuitive sensation in your stomach that guides your decision-making process or influences your emotions? It turns out that these gut feelings are not just figments of our imagination but are deeply rooted in the fascinating world of the enteric nervous system (ENS).
The enteric nervous system, known as the "second brain," is a complex network of neurons located in the walls of our gastrointestinal tract. Functioning independently from the central nervous system, the ENS regulates various gastrointestinal functions such as digestion, nutrient absorption, and gut motility. It consists of approximately 100 million neurons.
The enteric nervous system and the central nervous system are in constant communication, forming what is known as the brain-gut axis.
The two systems exchange signals and information through the sympathetic and parasympathetic branches of the autonomic nervous system. This interaction allows the brain and the gut to influence each other's activities.
When we experience emotions or stress, the brain sends signals that can affect the functioning of the enteric nervous system, leading to changes in gut motility and sensations.
This connection explains why we may experience "butterflies in the stomach" when we're nervous or have a "knot in the stomach" when feeling anxious.
The enteric nervous system produces and releases various neurotransmitters and hormones, including serotonin, dopamine, and gamma-aminobutyric acid (GABA). These chemicals play a crucial role in regulating our mood and emotions.
Serotonin, often referred to as the "happy hormone," affects our mood, appetite, and sleep. The majority of serotonin is actually produced in the gut, not the brain. Research suggests that imbalances in gut serotonin levels can contribute to mood disorders such as anxiety and depression.
Dopamine, known as the "reward hormone," regulates feelings of pleasure and motivation. It plays a role in our gut-brain interactions and can influence our gut feelings.
GABA, an inhibitory neurotransmitter, helps calm down overactive nerve impulses, reducing feelings of anxiety. Like serotonin, GABA is also produced in the gut and can influence our emotional well-being.
In addition to this, your microbiome (gut bacteria) also play a role in this exchange. Recent research has shown that the gut microbiota can communicate with the enteric nervous system, influencing our emotions and behaviors.
Imbalances in the gut microbiota have been linked to psychiatric disorders, including anxiety and depression. The gut microbiota can produce neurotransmitters, interact with the enteric nervous system, and even influence the production of mood-regulating compounds.
The enteric nervous system, functioning as our second brain, communicates with the central nervous system and the gut microbiota, impacting our mood, decision-making, and overall well-being.
Next time you experience a gut feeling, remember that it's not just a hunch; it's a manifestation of the intricate communication between your enteric nervous system and your brain.
