For decades, the general practice of medicine undermined the actual cause of any health-related problem. Practitioners believed then that there was no need to understand the cause as long as the problem was solved. Consequently, the medical and scientific communities underestimated brain dysfunction, the fundamental cause of these irregularities.
In a manner akin to the ever-evolving world of technology, medicine is also in a state of continual advancement. The traditional model for understanding the human body has revealed numerous deficiencies. These include the inadequate treatment of chronic illnesses, the escalating prevalence of obesity and metabolic diseases, and autoimmune disorders. Additionally, there are growing concerns with neurodegenerative conditions such as autism, Alzheimer's, and Parkinson's disease in both the developing and aging populations. These issues persist because the pivotal roles of the two most crucial systems for overall health — digestive (gut) and nervous (brain) — have been overlooked.The gut and the brain are connected through a two-way communication channel that mediates gut sensations and responses. These links are vital for both emotional well-being and optimal gut function. This connection between the gut and brain is also known as the brain-gut-microbiome axis.The emergence of research into the gut microbiome/microbiota — the complex community of microorganisms that live in the digestive tract — has yielded profound discoveries. Studies showed that the gut microbiome’s composition, variety, and functionality change throughout a person’s life.The well-being of the gut microbiota depends on the food you consume; the microbiota processes the food consumed into metabolites, the end products or intermediates of metabolic reactions. They travel through the bloodstream transmitting long-distance signals that influence every organ, including the brain.Keen to learn more? This summary is for you!

Our emotional states, typically displayed through facial expressions, also have a corresponding manifestation in our gut, even though this can't be seen externally.For example, during emotional moments, you might experience stomach knots, butterflies, or a gut-wrenching sensation — it's the emotion-generating circuits in your brain at work. Therefore, there's a unique link between emotions, the brain, and the gut.Sometimes, strong emotions can cause digestive issues like nausea, a rumbling stomach, bloating, or even pain. Many people who have these stomach problems don't realize that their feelings are partly causing them. They think it's just a physical problem. However, problems like irritable bowel syndrome, constipation, indigestion, and functional heartburn, are all categorized as brain-gut disorders.
