<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 4 yrs old grandson has been having vomiting but only in the morning. Has a high wbc. 13000. Has had us that was normal and has seen doctor 3 times. Waiting for other bloodwork that will be back tomorrow. He co stomach pain around midabdomen. He does not vomit after 10am only in the mornings.  <response>: Hi, Thanks for asking. Based on lab reports and clinical findings, my opinion is as follows:1. Vomiting early in the mornings could be due to gastritis. 2. Stomach pain around mid-abdomen also confirms a possibility of gastritis due to improper food habits.3. WBC of 13000 for 4 years age is normal. You are looking at it in comparison with adult values of 4-11 thousand. Its only gastritis, try to improve the diet. Any further queries, happy to help again.
