Hi guys. I am thin, 20 year old male. Non-smoker/no alcohol etc. overall good condition.
This week I started uni again, and a couple days before (Saturday) I started getting a lot of burping/gas - have been going to the toilet twice a day on most of these days over the last 5 days or so. Burping has reduced now, but still am pretty gassy. Stools are normal colour/consistency - maybe slightly on the hard side. Any ideas what it could be due to?

A heads up is that around this time I'm pretty anxious/nervous so maybe this has to do with it?
