These reasons for flatulence – are up in the air:
Eating habits: Among the most important and most frequent triggers of flatulence are "wrong" eating and nutrition habits.
Eating speed: Hasty eating can lead to a large amount of air being swallowed with the food, which then reaches the digestive tract.
Certain foods: Gas-generating food can cause flatulence: lentils, beans etc. Also, very luxuriant, greasy or sweet foods may cause flatulence, as well as excessive alcohol and coffee consumption.
Sugar substitutes: Sugar substitutes such as sorbitol or xylitol, which are found in many diet, light and sugar-free products can also be a trigger.
Stress: Digestive problems may result from a high and persistent level of stress.
Food intolerance: Especially the intolerances of lactose and fructose can cause flatulence: Both sugars pass undigested through the digestive tract due to missing internal enzymes for digestion or uptake. The bacteria in the intestines are “happy” about this additional food in the large intestine- but produce gas by digesting these sugars.
Imbalance in the intestinal flora: People who suffer from flatulence may show a different composition of the bacterial intestinal flora compared to people not showing flatulence.
Intestinal bacteria: The majority of intestinal gas is formed by the intestinal bacteria themselves - as part of the normal digestive process. This process can be intensified by certain foods - fibre contained in vegetable food is rightly regarded as healthy, but it can also cause flatulence.
