My client had a valve replacement approx one year ago. Recently he has had constant heartburn,burping, hiccups and indigestion.. Sometimes leaving him short of breath. He takes Zantac daily and tums as needed but lately nothing seems to help. It's especially bad after meals. He has occasional constipation but generally we can get those moving with MOM. I feel we have tried EVERYTHING and I'm asking if anyone has any answers for us. His surgery has left him unable to walk, of course, he is 94. Heart Drs. say everything looks ok there but I'm worried about possible blockages in the stomach/esophogus.
