When you trap gas inside, it doesn’t just disappear—it builds up. This can lead to abdominal bloating, cramping, and a general feeling of tightness or pressure in your gut. It’s like your body’s way of saying, “Please… let it go.” Holding in gas increases pressure in the intestines. Over time, this can cause distension and strain on the walls of your colon. While it’s not dangerous in the short term, constantly resisting the urge may not be the best idea for your digestive tract.
