This is an off-the-cuff response so maybe I'm completely wrong, but I recently started baking sourdough at home with my own starter. The starter is simply flour and water, but after a while of refreshing with new flour and water eventually the ever-present wild yeast and (good) bacteria start to grow really quickly. I usually wrap with saran wrap and when the starter is really active the saran wrap expands a bunch. From what I understand this is the gas from the bacteria eating their way through the flour. Could excess gas in humans be a similar situation? ie lots of gas means our microbiome is busy eating and farting a bunch. Which to me sounds like a good thing. Maybe not so good for those around you.
