When yawning is accompanied by nausea and dry vomiting, it should be taken seriously. Cerebrovascular disease such as cerebral infarction or cerebral haemorrhage should be suspected at this time, as the combination of cerebrovascular disease can lead to increased intracranial pressure or fluctuations in blood pressure, which can cause nausea, vomiting, headache, dizziness and other related symptoms, and a head-related examination should be carried out at the hospital as soon as possible to determine whether there are cerebrovascular problems.
