自己做一個小試驗，下列三種非處方藥，看看哪種有效，既能幫助您診斷，又能治療...

1. Activated charcoal tablets, such as CharcoCaps, may decrease odor from gas. Charcoal is usually taken after meals or at the first sign of gas discomfort.

2. Antacids, such as Maalox Anti-Gas and Mylanta Gas, allow gas to be belched away more easily. But these medicines often have no effect on gas that is already in the intestines.

3. Food enzymes, such as Beano, which help break down the sugars found in vegetables and grains, can be added to foods that cause you to have gas.
