Gastrointestinal flu is quite common in clinical practice, primarily characterized by discomfort in the gastrointestinal tract and symptoms of a cold. Patients may experience abdominal pain, diarrhea, vomiting, fatigue, and may also exhibit fever and cough. Gastrointestinal flu is mostly caused by rotavirus infection and is more common in the summer and autumn seasons. Irregular eating habits and rest patterns can easily trigger it. The main treatment involves using anti-cold medication symptomatically as well as medication to regulate the gastrointestinal tract. During treatment, it is crucial to maintain regular eating habits, rest adequately, drink plenty of water, and ensure proper hydration. Gastrointestinal flu can also lead to dehydration, which must be carefully monitored.
