Drink a Carbonated Beverage

• One of the simplest and most basic ways to help remove gas from the stomach may also be one of the most universally accessible: carbonated water or sodas, which are readily available in vending machines and convenience stores and sold under a variety of brand names. The fizz in soda comes from an injection of carbon dioxide gas added by soda bottlers. After ingestion, this gas expands in the stomach and encourages belching; when you belch, the soda's carbon dioxide and other gasses trapped in the stomach quickly and painlessly escape through the mouth.
  
  

Drink a Tea

• Noncarbonated hot teas with ingredients such as chamomile, peppermint and fennel can remedy gas in a different way. When ingested (usually as a tea, but also though other means such as chewing leaves), these herbs relax muscles in the stomach and intestines that trap and hold gasses. As the muscles relax, the gas slips more easily through the digestive system, reducing pain and making a more timely exit. People in India, according to Total-Health-Care.com, also make teas out of herbs and spices such as garlic and cumin for gas relief.
  
  

Take a Pill

• If home remedies don't work or if stomach gas becomes exceptionally painful, you may find relief through over-the-counter medications. Commercial anti-gas products contain the ingredient simethicone, which helps break up gas bubbles so they pass more easily through your digestive system. Antacid products also sometimes include simethicone to fight gas. If you use one of these combination products, be aware that antacids can react adversely with other medications you may be taking, including some antibiotics, according to WebMD.
