Stomach issues started few weeks back and had change of bowel habits going from constipation to loose bowels even in same day. Was getting bloating and flatulance but this has lessened a bit since stopping milk mostly. Now I seem to just have ended up with constant burping from the moment I wake to moment I go to bed even on an empty stomach. They have checked for ovarian cancer due to bloating and abnormal CA125 test but scan was all fine and now can’t get another GP appt for 3 weeks so looking for any ideas of what can reduce the burping in the meantime??
