[|Human|] My mother has colon cancer and tumors around her stomach. About a week ago she started vomiting and cannot seem to eat. Therefore doesn t want to. What could be causing her to vomit so much. They have tried an anti nausea cream to her wrist and still nothing. I got her to eat chicken noodle soup and tapioca pudding over a 3 hour period. About 2 1/2 hours after the soup, she threw it all up. It was very brown.
[|AI|]  Thanks for your question on Chat Doctor. Yes it is the cancer itself which is causing vomiting. There are many causes for vomiting in colon cancer patient.1. Obstruction in the bowel. Due to this food does not propel further and cause vomiting. 2. Hyperacidity and gastric ulcers.3. Compression of stomach and duodenum due to surrounding enlarged lymph nodes.4. Chemotherapy Chat Doctor.  So causes are many. But treatment options are limited. Try ondansetron tablet. As this is specifically used for vomiting associated with malignancies.
