hello doctor, my mother had heart angioplasty 3 months back and then after she went thru bypass surgery. After surgery she is hving problem in breathing..before agiopasty/bypass there was no problem related to breathing. doctors have done endoscopy yesterday to check the problem and they found that there is some infaction in the food pipe. which is causing breathing problem. She is Apollo ICU Delhi. this breathing problems come for an hr in a day. My mother has tough time durind that hr. I want to know that..infaction in food pipe can really be the cause of breathing or should we think of some other diagnose?
