What's the mechanism of action for lactose causing stomach irritation? Lactase isn't found in the stomach so it can't be lactose intolerance (as in the common meaning of the phrase, ie. lactase non-persistence).
- wahern 10y agoMicroflora in your gut. That's what lactose intolerance basically means--it doesn't directly harm you, but when it's not taken up by the intestines because you lack the lactase enzyme it's consumed by microflora, which create gas and other issues. Kinda like beans which haven't been properly prepared and contain too much non-digestible starch. It's also why some people who are genetically completely lactose intolerant can actually consume quite alot of lactose, and conversely why people who are genetically lactose tolerant can suffer from gastrointestinal issues pretty easily from dairy products, especially if they haven't consumed them in awhile. The tolerance or intolerance boils down to how the microflora react, not specifically to whether the person produces lactase.

- wahern 10y agoDid the previous poster edit his comment? I realized after the fact that you appeared to be responding to something different from what the post currently states.
- mrob 10y agoNot as far as I know. My response was to "tolerance or intolerance boils down to how the microflora react", which does happen after the stomach, so it seems unlikely that it could influence stomach irritation.
