Can constipation cause upper gastric pain (pressure/stabbing) mainly on the right side? also gas & bloating after eating. passing gas with eating fennel.gallbladder already removed. i also have gerd.

Yes: Constipation can cause that pain and pressure, bloating and passing gas that you describe. Try eating a lot of fruits and veggies for roughage and drinking 64 ounces of water. If that does not work natural calm works probably the best that I have found. It has magnesium in it and you can start with a teasoon and work up to the amount that works for you and it will keep you regular and feeling good.

Yes: Yes it can. Check and review these issues and possible dietary and other management issues with your doctor.
