In modern medicine, the sudden turmoil disorder described in the Donguibogam largely corresponds to acute gastroenteritis, particularly food poisoning or acute enteritis. When spoiled food or items contaminated with bacteria or viruses are consumed, the digestive system, especially the stomach and intestines, mounts an acute inflammatory response. This condition extends beyond simple indigestion, triggering an alert across the body's complex internal networks.
The initial disturbance occurs in the gut microbiota. When harmful bacteria multiply rapidly or produce toxins, they cause direct injury to intestinal mucosal cells. This impairs the absorption of water and electrolytes while accelerating fluid secretion, leading to diarrhea and, in severe cases, electrolyte imbalance and dehydration. This sequence closely mirrors what the Donguibogam described as a disruption of fluid metabolism.
Furthermore, the digestive tract communicates closely with the enteric nervous system, often referred to as the second brain. Harmful substances and inflammatory mediators stimulate the enteric nervous system, sending signals through the vagus nerve to the vomiting center in the brain. The brain responds by triggering retrograde gastrointestinal motility, inducing vomiting. While this is a protective reflex designed to expel toxins quickly, it brings significant discomfort. The classical description of qi being twisted reflects this acute disturbance across the nervous system.
Additionally, acute gastroenteritis activates a systemic immune response. When the intestinal mucosa is compromised, intestinal permeability increases, allowing irritants into the bloodstream and sparking systemic inflammation accompanied by fever, chills, and muscle pain. As inflammatory mediators such as cytokines are released, the entire body enters a heightened state of defense. This process aligns with the Donguibogam's view that hypofunction of the spleen and stomach represents a whole-body disruption of qi rather than localized stomach upset. Modern management of acute gastroenteritis similarly looks beyond symptom suppression, aiming to restore gut health, maintain fluid and electrolyte balance, and stabilize the immune system.
