Intracranial hypertension vomiting is characterized by jet-like vomiting, which usually occurs when the headache is severe, easily after eating, and can sometimes lead to electrolyte disturbances and fluid loss in the body. This is one of the most important objective signs of increased intracranial pressure. Patients may have blurred vision, and the recovery of vision is not always obvious. Patients may show drowsiness, unresponsiveness, coma, or eventually die due to respiratory and circulatory failure, so once patients have the characteristics of intracranial hypertension, such as vomiting and headache, they should promptly consult a hospital for treatment.
