Digestive issues
Some studies have shown that stress may lead to digestive issues, such as constipation, heartburn, diarrhea, and digestive disorders. For example, a study done in 2010 that focused on 2,699 children discovered that exposure to stressful events was linked with increased rates of constipation. Stress may particularly affect those with digestive disorders such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD).
You must understand that many other factors can lead to digestive issues, such as diet, bacteria, infections, certain medications, and more.
