Skinny Jeans, Tight Pants and Digestive IssuesTight clothing that pushes into the abdomen, everything from jeans to belts and compression undergarments, can be problematic, "particularly and especially when somebody overeats,"
Pressure on the stomach, known as intragastric pressure or intra-abdominal pressure, can trigger acid reflux — pushing stomach acid back up through the lower esophageal junction, where the esophagus and the stomach meet, causing heartburn.
Acid reflux is common, and not just for older adults, according to Dr. Koufman, who says about 37 percent of the 20 to 30-year-old age group gets it. Even someone who isn't prone to acid reflux can develop reflux if they wear a tight article of clothing often over a two-week period, she says. Snug-fitting corset-style shirts can have a similar effect.
