Hi. I m a 62 year old male. For months Ive been experiencing the following symptoms with no idea what could be causing them. First, after waking in the morning I often feel nauseous and sometimes experience drive heaves, especially while brushing my teeth. Lately I ve also been having difficulty eating. While I have an appetite the thought of most foods are completely unappealing, even my favorites. I m forcing myself to eat at times but nearly vomit while doing so. Several months back I had an endoscopy but the only abnormally found was Barrett s syndrome. Symptoms seem to be getting worse and I m getting more and more concerned. Any thoughts or ideas would be appreciated.
