Have a hiatal hernia and ibs. can ibs cause more reflux? i get severe reflux and have been constipated for 4-5 days. ive taken a laxative but takes 6-12 hours to work. have severe nausea. as well as bloating from all the gas. not sure what to do?

IBS is a group of symptoms but I don't see a clear effect on a hiatal hernia. If you take fiber for constipation be sure to drink plenty of water with it or else gas formation can be severe. Drinking hot water or applying heat to the abdomen helps break down gas into smaller bubbles. Drink flat ginger ale for nausea. If you have the urge & can't move, use dulcolax suppository or fleets enema.
