Why do i have so much gas lately?! ok lately i have had so much gas, it is crazy and it smells horrible. sorry to be so graffic. my eating habits have not gotten worse, a little better in my opinion. i have been eatting a banana a day and drinking water.

I : I agree with the previous answer. In addition, consider gum chewing which can lead to the ingestion of sorbitol which commonly causes gases. Also, do not forget the fact that eating rapidly can lead to aerophagia (swallowing of air). Further, avoid carbonated soft drinks which tend to produce excess gases. Good luck.

Intestinal : Intestinal gas is formed when undigested material -- usually carbohydrates -- reaches your colon, where bacterial fermentation produces gases: mainly methane, hydrogen and carbon dioxide. You mentioned that you were eating "a little better." often that means your fruit, vegetable and fiber intake has increased, and these foods are notorious for producing more gas. You could also be developing lactose intolerance (it's actually quite common), a condition characterized by an inability to digest milk sugar, which then becomes another carbohydrate source for bacterial fermentation. There are several options. Beano, an over-the-counter enzyme that helps break down starches, is particularly helpful for reducing gas caused by legumes (beans, peas, peanuts) and cruciferous vegetables (broccoli, cabbage, cauliflower, etc.). If you think you're lactose intolerant, avoid dairy products and use lactaid (the lactase enzyme that breaks down lactose). You could also try "re-adjusting" your intestinal bacteria by taking a probiotic supplement, available at any health-food or natural supplement store. Get a probiotic with at least 4 different strains of organisms, and buy from a store that keeps their probiotics refrigerated (they last longer). Probiotics take a week or two to re-colonize your colon. Finally, digestive enzymes -- also available at supplement stores -- may improve the breakdown of food in your upper intestine and prevent undigested material from reaching your colon. Hope that all helps. Good luck!

Bananas can lead: To flatus ; GI upset in some people.
