It’s easy to think of digestion as a one-way process,  but the conversation between your gut and your brain is far more complex. From mood to memory to overall well-being, this “gut-brain axis” plays a critical role in how we feel and function every day.

In this episode, Dr. Ginger Hultin sits down with Dr. Vivian Asamoah, a board-certified gastroenterologist and internal medicine physician, to explore the fascinating science of how your microbiome communicates with your brain. They break down what the gut-brain connection really means, the role of the microbiome and vagus nerve in mood regulation, and why paying attention to digestive health can have ripple effects on mental clarity and emotional balance. Dr. Asamoah also shares practical advice for recognizing gut signals that shouldn’t be ignored,  and what they might be trying to tell you.

If you’ve ever wondered how food, stress, and microbes shape your mindset, this episode will change the way you think about your gut.
