Gas: What’s Normal and When to Be Concerned
Gas is something that everyone experiences, but the reasons behind it can vary. Sometimes, excessive flatulence can be a cause for concern. To help shed light on this topic, CNN is launching a new eight-part guide called Eat, But Better: Mediterranean Style, which explores an expert-backed eating lifestyle that promotes good health.
Dr. Mark Corkins, a pediatric gastroenterologist at the University of Tennessee Health Science Center, explains that there are two sources of gas in the body. One source is air, which is mostly odorless and is swallowed by everyone to some extent. The other source is real gas, which is produced when food ferments in the colon. The colon is home to billions of bacteria, which digest our food. When food is not properly digested, it becomes a source of gas.
Passing gas between five and 15 times a day is considered normal, according to Dr. William Chey, a gastroenterology professor at the University of Michigan. Many factors influence how often someone passes gas, including the functioning of their gastrointestinal tract, the microbiome living inside the tract, and their diet. However, the frequency and smell of gas are not strong indicators of gut health. Bowel movement frequency and texture are more accurate indicators.
Dietary choices can impact the amount of gas produced. Some foods are more difficult to digest and more likely to ferment, leading to excessive flatulence. Beans, for example, are high in FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), which are short-chain carbohydrates that some people struggle to absorb. Other foods high in FODMAPs include cauliflower, garlic, apples, peaches, milk, wheat, and high fructose corn syrup.
Certain individuals may also experience increased gas production after consuming red meat or excessive carbs. Constipation can also contribute to excessive flatulence, as slow bowel movements allow for more interaction between food and bacteria in the colon, leading to increased gas production.
It’s important to consult a doctor if excessive gas causes discomfort or interferes with daily life. A doctor may assess factors such as diet, the microbiome, and gastrointestinal function to identify potential solutions. A low FODMAP diet can be beneficial for some individuals. Additionally, if excessive flatulence is accompanied by unintentional weight loss, blood in the stool, changes in bowel habits, or frequent diarrhea, it’s crucial to seek medical attention as these may be signs of underlying issues.
While waiting for a doctor’s appointment, individuals can keep a “gas diary” to track patterns and identify potential triggers. Over-the-counter remedies such as simethicone, activated charcoal, enteric-coated peppermint oil, or probiotics may also be suggested by a healthcare provider.
Overall, understanding the causes and symptoms of excessive flatulence can help individuals make informed choices about their diet and seek appropriate medical intervention when necessary.
