How can i help my teen with bronchiolitis and vomiting?

Bronchiolitis: is a disease that young children get, not teens. Perhaps you are referring to bronchitis? If he/she is vomiting a lot, you should have them take small amounts of fluids more frequently & advance that slowly. If it's happening just w/ coughing, a cough med might help or an inhaler. Your teen should see his/her doctor if there is continued coughing or vomiting or if he/she has not been examined yet.
