Gas and bloating are primarily caused by excess gas in the digestive system, which can result from several factors:

Causes of Gas and Bloating

• Swallowing Air: Eating or drinking too quickly, chewing gum, sucking on candies, drinking carbonated beverages, smoking, or wearing loose dentures can cause you to swallow more air, which leads to gas buildup in the stomach and intestines

• Fermentation by Gut Bacteria: When undigested carbohydrates (such as fiber, some starches, and sugars) pass into the large intestine, bacteria ferment these substances, producing gas as a byproduct. This is a natural process but can cause bloating if excessive

• Certain Foods: Foods high in fiber like beans, peas, fruits, vegetables, and whole grains can increase gas production. Additionally, sugar substitutes (e.g., sorbitol, mannitol, xylitol), carbonated drinks, and some food additives can contribute to gas and bloating

• Food Intolerances: Difficulty digesting certain foods, such as lactose in dairy products or gluten in grains, can cause gas and bloating. These intolerances lead to improper digestion and increased fermentation by gut bacteria

• Digestive Disorders: Conditions like irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), gastroparesis, and constipation can cause or worsen bloating by affecting digestion, gas production, or intestinal motility

• Constipation: When stool remains in the colon for a longer time, bacteria have more opportunity to ferment it, producing more gas and causing bloating

• Other Causes: Hormonal changes (such as during menstruation), infections, and certain gynecological conditions can also contribute to bloating

In summary, gas and bloating result from swallowed air, bacterial fermentation of undigested food, certain dietary choices, food intolerances, and underlying digestive conditions. Managing these factors can help reduce symptoms
