[/INST] Hi, The very first thing is to determine the type of virus that is causing such problems to your son. So, I suggest discussing with his doctor if your son is suffering from gastritis or HERD in order to start appropriate treatment. You are also saying that your son is a college boy. Being stressed out/anxious of exams and other college-related stuff would also affect him negatively leading to such problems. I suggest being close to him and support him, letting him know that you are proud of him whatever results he gets in the exams. If you cannot be close to him, you can ask to get helped by his friends or by medical team (psychotherapy). At the end, I also suggest going to his college, ask his teachers and classmates about his behavior to understand more his current situation. I also suggest getting blood/urine sample for Chat Doctor.  </s>
