Unobvious causes of bloating have been named

The cause of bloating may not only be overeating but also drinking through a straw, consuming onions, and an excess of sweets in the diet. British general practitioner from the UK's National Health Service Sami Kader shared this with the Mirror.

According to the doctor, one of the most common causes of bloating remains constipation. When the bowels are not emptied regularly, pressure builds up and gas accumulates in the intestines. Certain carbohydrates can worsen the situation: when they are broken down, intestinal bacteria produce hydrogen and methane. Such processes often occur after consuming onions, garlic, beans, sweets, alcohol, and carbonated drinks. Methane, in turn, can slow down bowel function, making bloating worse.

Among the less obvious causes, Kader mentioned food intolerances. In particular, unpleasant symptoms may occur with intolerance to lactose — milk sugar, fructose — sugar from fruits, as well as gluten — a protein found in wheat and certain other grains.

The doctor also identified a number of everyday habits that can trigger bloating. These include drinking through a straw, which causes a person to swallow more air, eating too quickly, chewing gum, and excessive consumption of carbonated drinks.

In addition, vaping and hormonal fluctuations affecting the digestive system can lead to bloating. The specialist noted that if such symptoms occur regularly and are accompanied by pain or other unpleasant manifestations, it is worth consulting a doctor to determine the causes.
