Patient's question:
No.Doctor's answer:
Normally, the anterior fontanelle is flat. When a baby vomits frequently or has diarrhea, leading to significant fluid loss, it can cause the anterior fontanelle to sink in. Meningitis, encephalitis, excessive vitamin A intake, upper respiratory infections, or other causes of high fever, such as roseola in infants, can cause the anterior fontanelle to bulge or protrude. When a small infant has a fever or experiences vomiting and diarrhea, it is important to pay close attention to changes in the anterior fontanelle. If it sinks in or bulges, seek medical attention immediately.
