Gut-Brain Connection in GI Symptoms

In this episode, we dive into mind-body science, starting with a focus on the gut-brain connection. We talk about the nervous system, gut microbiome, vagus nerve stimulation, and how behavioral medicine therapies such as CBT and hypnotherapy, along with mind-body therapies such as yoga, mindfulness, and breathing techniques can be used to help you cope with your GI symptoms. If you suffer from gastrointestinal symptoms such as gas, bloating, constipation, diarrhea, abdominal pain, nausea, heartburn, or even other symptoms when you eat such as headaches, fatigue, joint pain, and skin rashes, this episode might be important for you. Or even for those just curious in understanding better the connections between the gut and the brain, and what psychogastroenterology is all about, welcome!

I have also developed a quiz where you can find out if your gut-brain connection might be playing an important role in your GI symptoms:

Last but not least, if you prefer to work on your own at your own pace, I am launching a Gut-Brain Health online course, using psychology, neuroscience, and mind-body therapies to empower you with self-regulation techniques to cope with your gut disorders.
