Hi my father is 77 and he has no apatite, when he tries to eat, he wants to vomit and if he keeps food down it results in instant belching. He just came back from the ER and his blood and CT scan came back good. He has had worsening memory loss over the past couple years with it being more noticeable in the past few months. He s normally very cheerful, but he says he knows something is wrong, but he can t really describe it. He seems depressed and I can see it in his face.
