Uncomfortable or painful, stomach gas may lead to abdominal bloating and flatulence. The gas can occur as a by-product of digestion or as a result of gas consumption while drinking carbonated beverages. While the specific foods that cause stomach gas may differ from person to person, some common types of foods are linked to gas production.
High-Fiber Foods
Foods that contain larger amounts of fiber than your body is used to may cause stomach gas. Dietary fiber -- the indigestible material found in plants -- plays a role in the health of your digestive system. Dietary fiber in food adds bulk to your stool and absorbs water, helping food pass through your digestive system efficiently, preventing constipation. While dietary fiber forms an essential part of your diet, consuming large amounts of fiber -- especially if your body is used to a relatively low-fiber diet -- can cause digestive upset and gas. To avoid painful gas, increase your dietary fiber intake slowly, eating small amounts of fiber-containing foods throughout the day.
Dairy Products
Consuming dairy products may lead to stomach discomfort and gas. Dairy products contain lactose, the naturally occurring sugar found in milk. In the digestive system, the enzyme lactase helps your body digest lactose. Lactose-intolerant individuals lack a functional lactase enzyme, and therefore cannot digest milk and dairy products properly. The incomplete digestion of lactose leads to the accumulation of gas in the digestive tract. If you suffer from lactose intolerance, consume over-the-counter medications containing lactase along with dairy products to avoid painful gas.
Carbonated Drinks
Carbonated drinks, such as beer, soft drinks and sparkling water, may also lead to stomach gas. These products contain dissolved gases that provide the beverage with its fizziness. As you drink a carbonated beverage, most of the gas escapes into the air, but some of the dissolved gas may remain in the liquid and enter your stomach. After ingestion, the gases released from the beverage accumulate within your stomach and intestines. Avoid carbonated beverages to prevent the pain and discomfort that can result from stomach gas.
