Why Do I Have So Much Gas? 6 Causes of Excessive Gas

Updated in May 2022

Gas is naturally produced by bacteria that ferment and breakdown food during digestion. Most times, gas is odorless and not a sign of a health problem. In addition to production from bacteria, gas can also emerge after eating too quickly, as air can enter the digestive tract and accumulate within the intestines. 

Gas formation may also be a side effect from antibiotic. It may also be from eating food that takes longer to digest, as these foods tend to stay longer in the intestines and are more fermented, resulting in a higher concentration of gas. Slowly digested food can cause gas with a foul odor as well as symptoms like bloating, general malaise and sharp abdominal pain.
