5 week old boy is brought to the physician of vomiting for 3 day. Switching from a cow™s milk-based formula to a soy-based formula and one bottle of an electrolyte solution has not decreased his vomiting. His mother says that there is no yellow color to the vomitus, but it is forceful and occurs immediately after he has had 1 to 2 ounces of liquid. He appears to vomit more liquid that he drank. He has one mustard-colored seedy stool daily. Exam is normal. Which of the following is the most likely explaination for his vomiting?
A. Duodenal atresia
B. gastroesophageal reflux
C. Hypertrophic pyloric stenosis
D. lactose intolerance
E. Protein malabsorption
F. Rotavirus infection
