Gutbrain communication affects mood from "summary" of The Mind-Gut Connection by Emeran Mayer
The way your gut and brain communicate can have a profound impact on your mood. This communication occurs through a network of nerves, hormones, and chemicals that constantly send messages back and forth between your gut and brain. When this communication is disrupted, it can lead to mood disorders such as anxiety and depression. One key player in this communication is the vagus nerve, which acts as a direct line of communication between your gut and brain. When your gut is upset, it can send signals through the vagus nerve to your brain, triggering feelings of unease or distress. On the other hand, when your brain is stressed or anxious, it can send signals to your gut, leading to symptoms like stomach pain or bloating. The gut is also home to a complex ecosystem of bacteria known as the microbiome. These bacteria play a crucial role in the gut-brain communication network, producing chemicals that can influence your mood and behavior. When the balance of bacteria in your gut is disrupted, it can lead to changes in your mood and mental health. In addition to the microbiome, the gut also produces a variety of hormones and neurotransmitters that can affect your mood. For example, the gut produces serotonin, a neurotransmitter that is often referred to as the "feel-good" chemical. When levels of serotonin are low, it can lead to feelings of depression and anxiety.- The communication between your gut and brain is a complex and dynamic process that can have a significant impact on your mood. By taking care of your gut health through proper diet, exercise, and stress management, you can support a healthy gut-brain connection and improve your overall mood and mental well-being.
