Dysfunctions of the gastrointestinal tract, manifesting as symptoms such as excessive intestinal gas accumulation, queasiness, loose bowel movements, or persistent postprandial fullness, can substantially diminish quality of life and impair physical performance during exercise. A poorly balanced diet lacking nutrients tailored to the body’s requirements, coupled with suboptimal eating behaviors—including irregular meal timing or consuming food hastily—rank among the primary contributors to digestive malfunctions.
