Final answer:
Abdominal pain, vomiting, and fever are most likely due to gastroenteritis.
Step-by-step explanation:
Abdominal pain, vomiting, and fever are most likely due to gastroenteritis. Gastroenteritis, also known as infectious diarrhea, is an acute and usually self-limiting infection of the GI tract by pathogens. Symptoms typically include some combination of diarrhea, vomiting, and abdominal pain. Fever, lack of energy, and dehydration may also occur.
In many cases, the condition resolves on its own with adequate rest and fluid intake to prevent dehydration. For bacterial or parasitic infections, antibiotics or antiparasitic medications may be prescribed. Severe cases may require hospitalization for intravenous fluids and supportive care. Consultation with a healthcare professional is crucial for proper diagnosis and treatment.
