[|Human|] My father is in the hospital for over a week. He is unable to digest food, had vomiting, infection that can t be identified(White blood cell count was extremely high - but has now dropped), kidney issues-possible infection, constipation, etc. Today they did an endoscopy and said they could not see much because there was so much undigested food. Tomorrow, they are going to give him a barium test. They also said they were looking for some sort of blockage in the stomach. What could he have? My father had bladder cancer last year and was cleared and received BCG treatments just to be safe.
[|AI|]  Hi and thanks for the query, The problems in the stomach could be explained by a blockage generally called an intestinal obstruction. The past history could suggest the fact that maybe due to spread of a tumor, an intestinal region was affected, and the tumor mass is blocking the flow of food. It is also possible that abnormalities in the electrolyte metabolism, generally with low potassium levels could lead to constipation. Endoscopy and serum potassium should be checked first. Thanks and hope this helps. Kind regards
