Stomach Flu (Gastroenteritis)
Gastroenteritis (Stomach flu) is one of the most prevalent inflammatory gastrointestinal conditions. It is a non-specific presentation with multiple underlying etiologies. Despite having an excellent prognosis, untreated gastroenteritis can cause severe dehydration and even death.
