What are the most common causes of bloating?
You should keep in mind, however, that excess air in the stomach and intestines is most often caused by completely mundane things, such as too fast and greedy eating, speaking while eating, chewing gum, eating gas-forming foods, such as: beans, cabbage, brussels sprouts, onions, bread, pasta, cereal products, apples, pears, peaches, plums, corn, oats, potatoes, milk, ice cream, mould cheeses, purified bran.
Probably the most common and usually unconscious cause of flatulence is swallowing excessive amounts of air and often the inability to belch, i.e. to get rid of the swallowed air from the stomach. It is scientifically called aerophagia.
A natural gas-forming process is also the formation of gases in the large intestine as a result of fermentation (mainly carbohydrates, but not only) carried out by bacteria living there. The production of these gases may intensify when hard to digest and badly absorbed carbohydrates contained in legumes, brassica and onions reach the intestine.
Excessive fermentation may also be facilitated by lactose intolerance (dairy sugar), fructose (most of it is in fruits, fruit juices, honey), excessive consumption of sorbitol, insoluble fibre, etc.
Abdominal symptoms may also be caused by the so-called functional disorders of the gastrointestinal tract. These are disorders that are not based on any organic cause (structural or biochemical). Nevertheless, the symptoms can be very severe. Functional gastrointestinal disorders include:
- Irritable bowel syndrome (IBS),
- Irritable stomach (Functional Dyspepsia).
The less common causes to consider are:
- deficiency of pancreatic enzymes,
- inflammatory bowel diseases (ulcerative colitis, Crohn's disease, microscopic colitis),
- celiac disease.
