Causes
Gas can be caused by any of the following:
- Swallowing air while eating.
- Eating foods that are difficult to digest, such as fiber . If you recently introduced fiber into your diet, having gas may be temporary. Give it a little time. Your body may adjust and stop producing gas.
- Eating foods that you cannot tolerate -- for example, if you have lactose intolerance and eat dairy products.
