Normality of flatulence: after video by Ana Castela, doctors detail health and intestinal gases
Flatulence, a physiological process inherent to the human body, returned to the center of discussions after a video went viral on social media suggesting that singer Ana Castela had released gas during a performance on stage. The repercussion of the incident, which quickly became the subject of jokes and thousands of comments, brought to light the old social taboo surrounding the elimination of gases, especially when associated with public figures or women. Especialistas in health, however, reiterate that this is a completely normal phenomenon, regardless of gender, and even essential for digestive well-being, warning about the health risks of holding back gases.
According to medical data, a healthy adult eliminates, on average, around 1.5 liters of gas daily, with most of this volume being released during sleep. The frequency considered normal for a healthy person varies between 10 and 20 times a day. Tentar retaining these gases, a common practice among many people, can lead to significant discomfort and even health complications, as was the case with ex-BBB Pocah, who required hospitalization for this reason.
The discussion generated by the singer’s episode reinforces the importance of demystifying flatulence and educating the population about its physiological aspects and the care necessary for good intestinal health. Compreender the origin, characteristics and limits of gas production can prevent problems and promote healthier habits.
Physiological normality: what happens in the body?

The human body produces gases continuously, mainly during the digestion process and the fermentation of food in the digestive system. Essa production occurs when bacteria present in the large intestine break down carbohydrates that have not been fully digested, generating gaseous byproducts such as hydrogen, carbon dioxide, methane and, to a lesser extent, sulfur compounds. Esses gases accumulate and are expelled through the anus in a process known as flatulence.
In addition to bacterial fermentation, ingesting air during meals contributes to gas formation. Hábitos eating quickly, not chewing properly or talking while eating can increase the amount of air swallowed, which also needs to be eliminated by the body.

Warning signs: is excess gas healthy?
Excessive production of intestinal gas, accompanied by abdominal pain, bloating and frequent belching, may be an indication that something is not in balance in the digestive system. A diet rich in fermentative foods, known by the acronym FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols), such as beans, lentils, peas and onions, is one of the common causes. Estes compounds are poorly absorbed in the small intestine and reach the large intestine, where they are intensely fermented by bacteria.
Other factors that contribute to excess gas include food intolerances, such as lactose or gluten, and intestinal dysbiosis, which is an imbalance in the intestinal microbiota. Intestinal constipation also plays a significant role, as the prolonged time that feces remain in the intestine increases fermentation and, consequently, the production and bad smell of gases.
It is essential to see a doctor when symptoms associated with excess gas persist or worsen, manifesting as severe abdominal pain, constant bloating, changes in the evacuation pattern or unexplained weight loss. Esses signs may suggest more serious conditions, such as irritable bowel syndrome, celiac disease or other gastrointestinal pathologies that require specific treatment.
What is the characteristic of gases in a healthy person?
In healthy individuals, intestinal gases generally have a slight odor and the frequency of their elimination varies considerably, directly influenced by diet and lifestyle habits. A balanced diet, rich in fiber, but without excesses of highly fermentable components, tends to result in less frequent gas with a more discreet odor. The diversity of intestinal flora and the efficiency of the digestive process are determining factors for these characteristics.
Impact of holding back a “fart” on health
Retaining intestinal gas is a practice discouraged by health professionals, as it can cause a series of discomforts and problems. The pressure built up in the intestine can lead to bloating, a feeling of bloating, cramps and, in some cases, significant abdominal pain. Although there is no robust scientific evidence that holding in a “fart” occasionally causes serious long-term damage, repeating this habit can negatively impact well-being and intestinal functioning.
The medical recommendation is clear: releasing gases at appropriate times is essential to maintain intestinal health and avoid uncomfortable symptoms. Doctor Ivia Magalhães, member of Sociedade Brasileira of Motilidade Digestiva and Neurogastroenterologia, emphasizes that the natural release of gases is an integral part of the body’s proper functioning and a sign of an active and healthy digestive system.
Strategies to prevent excess flatulence
Preventing excess intestinal gas involves a combination of healthy eating and lifestyle habits. Adotar some strategies can significantly reduce discomfort and improve quality of life:
- Reduce the consumption of foods that cause gas: beans, cow’s milk and dairy products, peas, lentils, chickpeas, broccoli, garlic, cabbage and carbonated drinks are some examples. Para grains, soaking them for 12 to 24 hours before cooking can help reduce fermentable components.
- Improve eating habits: eating slowly, chewing food well and avoiding talking while eating are attitudes that reduce air intake, a contributing factor to the formation of gases.
- Practice physical exercise regularly: physical activity stimulates intestinal motility, facilitating the elimination of both gas and feces, which helps prevent constipation.
- Stay hydrated: drinking at least two liters of water a day is crucial for good digestion and avoiding constipation, a condition that can increase gas production.
- Include probiotics in your diet: foods such as natural yogurt, kefir and kombucha contribute to the balance of the intestinal microbiota, promoting more efficient digestion and reducing gas formation.
