My husband has developed big problems with his esophagus/sphincter. The sphincter was first lazered and has been stretched three times - he has had very little relief. Upon eating (or trying to eat) a meal he starts to choke. His throat and mouth suddenly fills with phlegm - like it suddenly bursts up and out of his mouth. He is really suffering from all this, and the doctors say there is nothing more that can be done. Do you agree? His weight went from 224 lbs. down to 173.lbs. Can you offer any suggestions? It s scary when he choke. It seems he doesn t lose much food -- just lots of phlegm. We would certainly appreciate your help/suggestions. Thanks for your consideration.
