The gastrointestinal tract is often referred to as "the second brain." When stress over-activates the sympathetic nervous system, it can halt gastrointestinal motility. This condition is known as "Ganbi-bulhwa" (Liver-Spleen Disharmony), implying that stress in the liver impacts the spleen. Therefore, simply taking digestive medications isn't enough; it's crucial to soothe the liver's energy (qi) to allow the digestive system to move properly again.
