Don't Wear Tight Clothes
Acid reflux has a variety of causes. In almost all cases, however, clothes that don't fit well can make your symptoms worse. Wearing clothing that is too tight frequently causes irritation and pain.
Michelle Rauch, a registered dietitian, points out that neckties and other tight clothing can aggravate gastrointestinal conditions like irritable bowel syndrome (IBS), Crohn's disease, and gastroesophageal reflux disease (GERD). A belt around the waist was found to cause more acid reflux after eating in one study. The belt's increased pressure on the stomach is most likely what caused this to occur. If you must wear one, go for a wide or loose-fitting style. Consider wearing a soft silk scarf instead of a tight leather belt around your waist, for instance.
