What could cause of excessive flatulence?

Flatulance: Milk & dairy products, starchy foods like potatoes & pasta, wheat & oat bran, artificial sweeteners in hard candy, bananas, peaches, apricot, raw apples, pears, raisins, mellons, prune juice, fructose in cola drink, beans & lentils, onion, green pepper, cauliflower, broccoli, brussel sprouts, peas, corn, celery, artichoke, carrots, asparagus.

Swallowed air/ diet: The digestive system is an elaborate tube from the mouth to the anus. All people swallow air when they eat & some take in more than others. You either belch it up or create flatus. If you eat foods that your body doesn't digest completely, the germs in your gut will & they create flatus in the process. Keep a food diary & keep track of what makes you gassy & avoid them.

Eliminate cause: Flatulence is excess gas produced in the digestive track due to usually something eaten that does not agree with you. Beans, cabbage and onions are common causes but so is gluten and dairy. I usually have people do an elimination diet of what they think is the offending agent and see what happens. Add probiotics twice daily in the beginning, smaller servings, eat more frequent. Beano helps too.
