How long after eating does flatulence occur?

Flatulence can occur anywhere from a few minutes to several hours after eating, depending on various factors such as the type of food consumed, individual digestion rates, and gut microbiota. Foods high in fiber, certain carbohydrates, and sugars can lead to increased gas production. Typically, gas may start to form within 30 minutes to 2 hours after a meal as the digestive process begins and continues through the hours following digestion.
