Frequent intestinal gas: the real causes that almost no one clearly explains

Food intolerances also play a key role. Substances such as lactose, fructose or gluten can be difficult for some people to digest. When the body is unable to digest these nutrients properly, they end up in the intestines, where they are fermented by bacteria, generating excess gases. Often, these intolerances go unnoticed for years, and their symptoms are mistaken for minor problems.

Additionally, there is a high intake of certain types of carbohydrates, known as FODMAPs, found in foods such as bread, legumes, and certain fruits. These compounds are highly fermentable, which means they are food for gut bacteria. Although not inherently negative, it can lead to excessive gas production in some people, especially in the case of pre-existing hypersensitivity of the digestive system.

A common, often underestimated habit is swallowing air. Eating too fast, talking while chewing or drinking through a straw are behaviors that promote air entering the digestive system. This air accumulates and is later released in the form of reflections or gases, causing discomfort. Although it may seem like a small thing, it can be a common cause of ailments.

In addition, there are digestive disorders that can exacerbate this problem. Disorders such as gastritis, intestinal dysbiosis or irritable bowel syndrome disrupt the natural balance of the digestive system. This affects the way food is processed, increasing gas production and leading to more persistent symptoms.
