Article: In addition to its other negative health benefits, smoking causes you to inhale excess air that may cause you to have excess gas. Stop smoking to reduce the amount of excess air that you swallow and help prevent excess gas. Stress and anxiety can cause you to have excess gas, so it is important to incorporate relaxation into your daily routine. Try meditation, yoga, or deep breathing exercises to reduce the amount of excess gas that you have as a result of stress and anxiety. Physical disorders such as irritable bowel syndrome (IBS), diabetes, and celiac disease will cause gas symptoms despite your best efforts to reduce gas in your system. Your doctor can prescribe medications to help you deal with IBS and other such chronic conditions.

What is a summary?
Quit smoking. Relax daily. Talk to your doctor about prescription medications if watching your diet or taking over-the-counter diet aids aren't helping your gas issues.
