My 88 yr old mother is in a Nursing home with alzheimers. She is being treated with Pcn for a UTI. Before tx begain she had episode of vomiting, that was one week ago Since then she has eaten very little. Is drinking some mostly chocolate milk. They increase her omeprazole 20mg to bid. She vomited again today. She will tell u that her stomach hurts and places her hand to epigastic region. She will take a few bites then she wont eat. Is this part of disease process with alzheimers . She has become weaker. We wouldn t put her through surgery. But would a KUB give us any answers. Her stools are different. LIke round balls, similar to a pea. They have always been loose before.
