Hello JR. This is in response to your message regarding your dad's inability to eat. I don't know if I have an answer for you, but it might be worth asking your doctors about a possible reaction to a medication. It could even be a very uncommon reaction that does not appear in the product literature. A few days after my quintuple bypass surgery in Sept. of 2002, the medication Imdur was prescribed for me. Within a day, my sense of taste and smell started to go berserk. At first I attributed it to the morphine from the surgery & thought it would just go away. It didn't. It got worse. Everything that I could taste or smell had one sensation - I called it "smaste" for lack of a better word. Mop water, food, my own skin, flowers - all had this same foul sensation. Within a day I could no longer eat food, and I had trouble choking down water. The only change in my treatment had been the addition of Imdur, so after a few days of no food, I requested that the Imdur be discontinued. I think the surgeon thought that I was just being wimpy, and said that I could die without the medication. I said that I didn't care, because I was going to die from starvation anyway. Even now, I can't find the words to describe the terribleness of "smaste," but even though I don't think that the doctor believed me, he finally agreed to discontinue the medication. Within a day, my normal sense of taste & smell started to return, and I was discharged from the hospital. The morning after my discharge from the hospital, I passed out & ended up back in the hospital ( a different hospital). Dehydration (no kidding) and too much blood pressure medication was believed to be the cause by another doctor. I think that they could have added "early stage of starvation." to the list. The thing that really nailed the problem down in my mind is when the new doctor somewhat irritatedly asked who put something like "reaction to Imdur" on my chart & asked me if I would start taking the medication again. I agreed to try it again because I wanted to be absolutely sure that the Imdur was the problem in case anyone tried to prescribe it again when I might be too ill to protest. To make a long story a little bit shorter, the same foulness returned, & the Imdur was discontinued. To this day, I think that the doctors thought that I was overreacting, and would not believe how serious a disrupted sense of taste & smell could be. The point of this long, somewhat drawn-out story is that we all react somewhat differently to different medications, and just because a doctor hasn't heard of a certain reaction and it's not on the drug company's list, doesn't mean that it can't occur. My problem may not relate to your father's, but it might be worth exploring. Good Luck. Art
