Diet? gut? GYN? CMD: Can be diet related-carbonated beverages, alcohol, malabsorbed sugars (lactose, fructose, sugars in bean products), sorbitol in sugarless gum; celiac sprue; can be swallowed air (straws, gulp, gum chewing, anxiety, smoking); meds; diverticula (pockets in the wall) of the small bowel, other bowel issues; colon problems including tumors; gyn issues, including hormonal changes, ovarian problems.Cmd.

Likely IBS: Excess gas is due to the interaction of your gut flora(bacteria) and the food you eat. Should try a low carb diet and take probiotics.

Digestion and Gas: General details about malabsorption: When someone cannot digest a nutrient, bacteria in the gut digest it instead, producing gas. Examples: some sugars (eg: lactose in dairy), sugar-alcohols ( "no sugar added!" sweeteners sorbitol/maltitol/xylitol), fat (happens w Alli & when people w celiac disease eat wheat/barley/rye). Treatment:Avoidance.Other reasons exist, and are covered by the other Docs
