Flatulence and wind are common symptoms experienced by most people. Such symptoms are related to gas in the gastrointestinal tract. The production of intestinal gas is a normal part of digestion. However, some people can experience excessive amounts, which can be uncomfortable and very embarrassing.

Diet and the colonic flora are typically linked to the type and amounts of gas produced. Intestinal bacteria produce gas. Experiencing the odd bout of wind is not uncommon. However, excessive amounts of gas may be related to a number of factors, such as: diets high in fermentable carbohydrates (i.e. pulses and bran), a change in diet (such as a sudden change to a high fibre diet), a change in the composition of the bowel flora, diarrhoea, constipation, IBS, malabsorption, bacterial overgrowth of the small intestine and lactose intolerance.

Be aware of any foods which may be linked to wind. A number of fruit and vegetables contain starches which are poorly digested. For example: beans, lentils, prunes, brussel sprouts, cabbage and onions.


Any changes in bowel habits warrant further investigation from a doctor and should not be ignored.
