Modern medicine offers a perspective on this that closely mirrors the insights of Donguibogam, demonstrating how traditional wisdom and contemporary science connect.
Today, irritable bowel syndrome is understood through the concept of the gut-brain axis. The gut and the brain communicate in real time along a pathway known as the vagus nerve. This vagus nerve continuously transmits signals back and forth between the brain and the digestive tract, playing an essential role in regulating digestion, nutrient absorption, and defecation, as well as influencing mood and emotional state. Donguibogam's observation that the seven emotions affect the large intestine aligns directly with the complex workings of this gut-brain axis.
Under stress, the brain releases stress hormones like cortisol, which immediately act upon the gut. This can heighten intestinal sensitivity, leading to visceral hypersensitivity. As a result, one may experience far greater pain or discomfort than others would from the exact same stimulus. It also disrupts intestinal peristalsis, resulting in constipation, diarrhea, or a confusing alternation between both.
Gut dysbiosis plays a major role as well. More than 100 trillion microorganisms live in the gut, and the digestive tract functions well when a healthy balance between beneficial bacteria and harmful bacteria is maintained. However, when stress or dietary patterns disrupt this balance, the intestinal mucosal barrier weakens and inflammatory reactions develop, which then negatively feed back into the gut-brain axis. The gut microbiota also produces roughly 90% of the body's serotonin, often referred to as the happiness hormone. When microbial balance is lost, serotonin synthesis is compromised, which can lead to a depressed mood. Many have noticed feeling down simply because their stomach is unsettled, illustrating how closely these systems are tied together.
In conclusion, irritable bowel syndrome is not merely a matter of having weak intestines. It is a multifaceted bodily signal arising from gut-brain axis dysfunction, imbalance in the gut microbiota, and psychological stress. Effective care therefore requires a comprehensive approach that addresses each of these elements together.
