Irritable Bowel Syndrome with Alternating Constipation and Diarrhea

The wisdom of Donguibogam is being re-examined in modern medicine. In particular, the recurring symptoms of constipation and diarrhea are characteristic of 'Irritable Bowel Syndrome (IBS)'. Recent research has revealed that IBS is not merely an intestinal problem, but originates from an imbalance in the 'gut-brain axis' where our brain and gut communicate closely. Just as Donguibogam explained the lungs and large intestine as an 'exterior-interior relationship', our brain and gut also deeply influence each other. When we experience stress or concern, the brain secretes various neurotransmitters, and these substances are directly transmitted to the intestines, which can excessively stimulate or, conversely, inhibit intestinal movement and peristalsis. For example, cortisol, the stress hormone, increases intestinal permeability, weakens the inflammatory response, and can disrupt the balance of the microbiota within the gut. This disrupts bowel rhythm, leading to the phenomenon where one day you suffer from constipation and another day you are troubled by diarrhea. The intestines house neurons comparable to the brain, producing about 95% of our body's serotonin, which is why it's also called the 'second brain'. This gives you an idea of how crucial the communication between them is. Furthermore, the importance of the gut microbial ecosystem, or the 'microbiome', cannot be overlooked. If the balance of beneficial and harmful bacteria is disrupted, inflammation can occur in the intestinal mucosa, or problems can arise in digestive enzyme secretion, leading to difficulty in food digestion and absorption. This can be a primary cause leading to gas formation, abdominal distension and bloating, and irregular bowel movements. Often, increased sensitivity to specific foods can induce abdominal pain or diarrhea. Westernized eating habits, antibiotic intake, and chronic stress are considered major factors that contribute to microbiome imbalance. In conclusion, modern medicine views Irritable Bowel Syndrome as a disorder that arises through the complex interaction of dysfunction of the gut-brain axis, gut microbiota imbalance, and visceral hypersensitivity. The concepts of 'qi' communication issues, the connection with the lungs, and Damp-Heat mentioned in Donguibogam are remarkably linked to stress, nervous system reactions, and intestinal environment changes. The key is not merely to focus on the intestines, but to understand the connection between the body and mind and to find balance.
