What are the symptoms of gastroenteritis?
The primary symptom of gastroenteritis is diarrhea (non-bloody). Nausea, vomiting, and some abdominal cramping may accompany the diarrhea; mild fever (about 100 F or 37.77 C), chills, headache, and muscle aches along with feeling tired may occur in some individuals. Vomiting is occasional and the symptoms usually last about 2 to 5 days and begin to resolve. Severe gastroenteritis means the person has signs of dehydration; this is a medical emergency.
Children with gastroenteritis usually have diarrhea, but may have other symptoms, sometimes conflicting, of refusing to eat or drink or are very thirsty, either increased or low or no urine output. Weight loss, lethargy, and pinched skin that does not rapidly go back to normal are signs of dehydration, along with decreased fluid intake.
