hello &welcome to hcm! The abdominal pain of your daughter is most possibly related to eating outside - eating stuff which is not cooked properly. So, it is not stress which is the causative factor behind it - but abdominal / gasrtic infection. The tablet perscribed is for the same and will help in reducing acidity. She should also try to eat only throughly cooked or boiled food from outside. Preffrably she should carry water with her when going out and avoid eating salad and curd from out ( as they are not cooked). She might need a dose of antibiotics depending on other symptoms for which she needs to see a doctor in person. Strees would have given her sleeping issues, anxiey or body weakness...not abdominal pain. Hope the reply is useful Please ask if you have anymore queries. Dr. Manisha Gopal MD Psychiatry
