My grandfather, 84, is suddenly experiencing a loss of apetite, difficulty swallowing and vomiting. Doctors have prescribed medications for peptic ulcer and inflammation without doing examinations and he got better for two days then it worsened again. He's diabetic, a smoker and has been taking cortisone as well as other medications for diabetes control. He hasn't vomited blood. I don't know if there's something that can be done or it's just the body shutting down. I hope you can help.
