[|Human|] My dad has stomach cancer. He went to the gym and swam and did water exercises. He got home and continued to vomit clear fluid. He takes oral chemo tablets and has for two years. Has blood test every two weeks and all is good. What could his vomiting bee caused by. He ate before he went swimming but says he feels very hungry now.
[|AI|]  Hi, Oral chemotherapy probably capacitative has been prescribed. Anyway the stage and treatment details you have not mentioned. Vomiting can be due to many causes. Chemotherapy irritates gastrointestinal tract mucosa and stimulate the vomiting center to cause the vomiting. This may be due to acute gastroenteritis too. You should observe the nature smell amount frequency and associated nausea during the vomiting episodes. If it repeats consult your oncologist.
