What Causes Excessive Gas, Farting & Belching?

Fact Checked

Although not dangerous or life-threatening, excessive gas might not get you invited to many social events. In fact, you might not even stand to be around yourself. However, gas serves a purpose and could be a sign that you are eating in a healthy way. Normal gas production is equal to at least 14 episodes of gas-passing per day. But it can be hard to know when too much gas is just embarrassing or signs of a bigger problem.

Foods You Eat

Most everyone has heard that beans will lead to gas, but other foods are culprits too. Broccoli or cabbage might be the cause. According to Mother Nature’s website, fruit juices, corn chips, wheat germ, pretzels and popcorn are high on the list of gassy foods. Also, any food or beverage with sugar can lead to farting because these are not digested as easily. Lactose, sorbitol and fructose are particularly problematic.

Swallowed Air

While you eat, you gulp air as well as food. Air swallowing is common. This can be increased if you eat quickly, while doing other activities or are stressed. Also, drinking too much at once or quickly will put air in your stomach. Too much air in the stomach leads to gastric distress and either burps or flatulence. Avoid gum-chewing or eating candy to reduce the amount of swallowed air.

Abdominal Conditions

Celia disease produces foul-smelling flatulence and abdominal distention. Chrohn’s disease or lactose intolerance both could lead to excess gas. Liver disease also produces abdominal symptoms of bloating and gas. Get checked by a medical professional for more serious conditions that might be the cause of your gas.


Using laxatives can certainly cause gas. Stimulant laxatives like Dulcolex are stronger acting and more likely to lead to abdominal cramping or painful gas. On the other hand, Metamucil adds water to the stool to form bulk and are less likely to produce too much gas. Before you use laxatives for long periods of time, check with a medical professional about frequency of use and other alternatives to a constipation problem.
