Which symptom class is commonly reported with the initial introduction of dietary fiber?

• A. Severe chest pain
• B. Joint stiffness
• C. Bloating and flatulence
• D. Nausea

Answer: (C)

When dietary fiber is introduced, gut bacteria begin fermenting the fiber in the colon, producing gases such as hydrogen, carbon dioxide, and methane. This gas buildup commonly shows up as bloating and flatulence, especially if fiber is increased quickly or includes highly fermentable soluble types. Gradually increasing fiber and staying well hydrated helps minimize these symptoms. Severe chest pain or joint stiffness aren’t related to fiber introduction, and while nausea can occur with some dietary changes, bloating and flatulence are the typical early GI responses to adding fiber.
