Excessive gas often signals poor gut health and inflammation, typically caused by imbalances in gut bacteria that lead to fermentation of undigested food. Conditions like IBS and SIBO are common culprits, with over 60% of IBS sufferers experiencing gas due to microbial disruptions, according to the World Journal of Gastroenterology. A 2019 study in Nutrients found that a low-FODMAP diet can reduce digestive symptoms, improving gas by 50%. Maintaining gut health through a balanced diet, probiotics, and avoiding trigger foods can significantly reduce gas and improve overall digestive health.
