Why Your Stomach Still Feels Uncomfortable Even on Constant Gastritis Medication

The importance of the stomach and the impact of tension described in the Donguibogam can also be clearly explained by modern medicine. At the center lies the connection called the gut-brain axis. Far from being a simple digestive organ, our stomach communicates closely with the brain, often called the second brain. Through the pathway of the vagus nerve, the brain and stomach exchange information in real time. When we experience stress or anxiety, the brain immediately sends signals activating the sympathetic nervous system. It triggers a state of alarm, tensing the body, and stress hormones like cortisol disrupt intestinal peristalsis while decreasing the secretion of digestive fluids. It is similar to shutting down digestive functions during an emergency, when the body does not have the leeway to process food. Blood supply to the internal organs decreases, preventing stomach muscles from moving properly. When this condition becomes chronic, decreased gastrointestinal motility sets in, prolonging the time food stays in the stomach and leading to symptoms such as chronic food retention and functional dyspepsia. Furthermore, stress negatively impacts the microbial ecosystem within the gastrointestinal tract, the microbiome. As beneficial bacteria decrease and harmful bacteria increase, the gut environment deteriorates. This triggers inflammatory responses or impairs neurotransmitter production, exerting negative effects back on the brain. The idea that an uncomfortable stomach leads to low mood is grounded in this interaction. Continuing to feel stomach discomfort despite taking gastritis medication is mostly due to these combined factors. Medication helps regulate gastric acid secretion or ease inflammation, but it cannot resolve decreased gastrointestinal motility or gut-brain axis dysregulation caused by stress. Because treatment often addresses only visible symptoms, the true cause—a disruption in the body's internal balance—remains unresolved, resulting in chronic discomfort. Stomach health extends beyond simple digestion, connecting deeply to the balance of our entire body and peace of mind.
