What causes episodes of fainting?
Patient: Grandson is 17 and needed to have bowel movement, was traveling and couldn t get to rest room at the right time, had to wait. passed out upon arrival at convenience store. Had also fainted one other time when a shot had to be administered. Is this normal for a teen? Doctor: Hello,I understand your concern on your grandson .I assure you it us nothing you have to worry about.In adolescents a lot of changes occur in a short period. Also their  behavior is changing rapidly.In my opinion the troubles of your grandson are caused be a so called vagal dysfunction. It is more common in this age because the nervous system is still not mature. Anxious situations too are the cause. He will grow up and everything will be all right.Hope to have been helpful.Thank you for using HCM.Best wishes Dr. Abaz
