Everybody experiences flatulence. On average, individuals expel gas over a dozen times a day. In some cases, though, excessive gas can become disruptive. By trapping gas in the intestines, laxatives force gas through the digestive system and are ultimately released through the anus. Many factors affect the frequency of flatulence, such as psychological state, aging, diet, and even swallowing air. Laxatives, which stimulate the activity of the bowels, can also increase the amount of gas released. Interactions with other drugs can sometimes work to increase gas. Always stay informed on interactions between laxatives and other medications to avoid negative side effects. Gas emissions usually return to normal after cessation.
