Gastroenteritis is mostly caused by improper diet leading to infections, resulting in symptoms like abdominal pain and diarrhea. Therefore, for gastroenteritis, one should register with the gastroenterology department. However, if the gastrointestinal symptoms are caused by a cold, then one should register with the respiratory department. It depends on the sequence of symptoms: if gastrointestinal symptoms appear first, registration should be with gastroenterology; if cold symptoms appear first followed by gastrointestinal complications, a registration with the respiratory department is possible. Yet, for resolving gastrointestinal symptoms, it is advisable to consult with the gastroenterology department as it is more appropriate.
