Head Injury with Vomiting: Signs of Increased Intracranial Pressure

Vomiting after head trauma can signal increased intracranial pressure (ICP)—a neurosurgical emergency. Other red flags:

• Worsening headache
• Confusion, drowsiness, difficulty waking
• Seizures
• Vision changes (blurred, double)
• Weakness/numbness on one side
• Unequal pupils

Action: Seek emergency care immediately if any of these occur.

Vomiting may also stem from nausea, vertigo, anxiety, or motion sickness. If vomiting persists >24 hours without red flags, still seek medical evaluation.
