how do i prevent Gas in stomach?

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.
• Irritable bowel syndrome -- a chronic form of stomach upset that gets worse from stress.
• Malabsorption (when your body cannot absorb or digest a particular nutrient properly, often accompanied by diarrhea).
• Antibiotics.

• Eat more slowly.
• Chew your food thoroughly.
• Avoid gum chewing.
• Relax while you eat.
• Avoid beans, cabbage, and carbonated beverages.
• Try Beano, a product sold over-the-counter at most drugstores, if you eat a lot of beans, fruits, vegetables, and other high-fiber foods.
• Walk for 10 to 15 minutes after eating.
• Drink peppermint or chamomile tea after a meal.
