There is no single “strongest” solution; the cause of gas matters. Quick relief may come from walking, warm fluids, slow breathing, and gentle abdominal massage. Nutrition is critical: reduce trigger foods (excess legumes, certain dairy, high-fructose items, very fatty meals), manage portions, and eat slowly. Medications like simethicone may provide symptomatic relief for some people, but persistent gas with pain or stool changes should be evaluated for intolerances (lactose, FODMAPs) or gastrointestinal conditions. Mineral water may help some individuals feel better, but can worsen gas in others.
