Intestinal Virus? - intestinal virus more condition_symptoms

How can I receive treatment for gastrointestinal-()-virus? My friend complains of bloating, diarrhea and intuition as "moved". She saw her doctor told her to wait. Has anyone experienced, and what is being done to relieve symptoms? BTW, was in Puerto Vallarta before 2 weeks.
