27. Air Swallowing
Air swallowing caused by:
1. Acid reflux or gastroesophageal reflux disease (GERD), which causes swallowing of air.
2. Swallowing air as a nervous habit.
28. Poorly functioning stomach/ intestinal muscles
In some people bloating may be due to the intestinal muscles not functioning properly, such that air is not transported through the digestive tract and expelled as it ought. Fats have a similar effect on the intestines. In both cases food, air and liquid accumulate causing bloating and/or distention.
