Abstract

Acute stress triggers a series of neurophysiological responses that directly affect gastrointestinal motility, influencing autonomic function and mucosal integrity. This study aimed to analyze scientific evidence published between 2021 and 2025 regarding the impact of acute stress on gastrointestinal motility in young adults. An integrative review was conducted in PubMed, ScienceDirect, SciELO, and Scopus databases using descriptors related to stress, gastrointestinal motility, and the gut-brain axis. Ten studies met the inclusion criteria, encompassing experimental and systematic research. Results show that acute stress decreases vagal tone, increases sympathetic activity, and causes transient alterations in intestinal motility, as well as affecting mucosal permeability and inflammatory modulation. It is concluded that acute stress has measurable and significant effects on gastrointestinal motility, emphasizing the importance of stress management strategies for digestive health maintenance.
