The perspective of the Donguibogam offers both comfort and clear insight. Looking at this ancient wisdom through the lens of modern science adds even deeper understanding. In recent years, the medical community has been actively researching the concepts of the gut-skin axis and the gut-lung axis. Modern science is illuminating, through the microbial world of the microbiome, the very link between the lung and large intestine that was recognized thousands of years ago.
Countless microorganisms live inside our intestines, forming an ecosystem called the gut microbiota or microbiome. These microorganisms govern more than 70% of our body's immunity, produce neurotransmitters, and exert a profound influence not only on digestion but also on skin health and even lung health.
When the balance of the gut microbiota is disrupted—such as in leaky gut syndrome—the barrier function of the intestinal mucosa weakens, allowing harmful substances to enter the bloodstream. Toxins entering this way trigger a systemic inflammatory response. When this inflammation manifests in the skin, it can lead to problems such as psoriasis, atopy, acne, and chronic dryness. Many people have likely experienced firsthand that when the gut is unhealthy, the skin becomes rough and loses its elasticity.
Furthermore, the gut and the lung are closely linked immunologically. Poor intestinal health can trigger a systemic inflammatory response that extends to the lungs, potentially leading to bronchial hyperresponsiveness or a chronic dry cough. Because the lung is an organ in direct contact with outside air, respiratory immunity is vital. A substantial portion of this immunity depends on gut health. The lung can breathe comfortably only when the intestine is at ease.
Moreover, chronic constipation creates a vicious cycle in which harmful bacteria proliferate and toxins accumulate in the intestine. These toxins damage the intestinal mucosa and spread throughout the body, worsening skin problems and placing a burden on the lung as well. This is why constipation can be interpreted not merely as a digestive issue, but as a warning sign for whole-body health. Modern medicine continues to unveil the intricate mechanism by which modern lifestyle habits—such as stress, irregular eating patterns, and diets centered on processed foods—disrupt the balance of the gut microbiota, leading to dry skin, constipation, and a dry cough. Through modern science, the teachings of the Donguibogam become even clearer.
