Which symptom is commonly associated with gastroenteritis?

Gastroenteritis, often referred to as a stomach infection, is characterized by inflammation of the stomach and intestinal lining. This condition is typically caused by viral or bacterial infections and leads to a variety of symptoms due to the effects of the inflammatory process on the gastrointestinal tract.

Abdominal pain and diarrhea are hallmark symptoms of gastroenteritis. The inflammation can cause cramping and discomfort in the abdominal area, while the irritation of the intestinal lining often leads to increased frequency and volume of stools, resulting in diarrhea. This combination of symptoms is commonly reported by individuals suffering from gastroenteritis and is key in distinguishing this condition from others. The other options represent unrelated or less common associations with gastroenteritis, making abdominal pain and diarrhea the most directly relevant symptoms.
