Hi doctor! I have 2 questions that I would like your advice on. Question 1: I have frequent stomach pain. Every time after eating, there are symptoms of nausea and vomiting. Lately, I've been eating poorly and have been suffering from stomach pain. Doctor, is it necessary to test for HP virus when having stomach pain?

Hi doctor. My name is Quynh Nhu, I am a freshman, 2 years ago, my stomach used to be painful and often had diarrhea, stools were rarely normal. Her parents took her to an endoscopy and test, took out the fluid to see if it changed color and the result did not change to pink and she also did not have the HP virus.
