Patients with cerebral infarction who experience vomiting must undergo timely relevant examinations. Cerebral infarction typically presents with symptoms such as dizziness, headache, and nausea. The presence of vomiting often accompanies the development of intracranial hypertension. At this time, it is crucial to administer an appropriate mannitol diuresis therapy to reduce intracranial pressure. Prompt use of metoclopramide injection or granisetron injection is also highly necessary, as these can effectively alleviate the symptoms of vomiting. However, it is essential to complete the appropriate examinations to clarify the changes in the intracranial condition. Vomiting caused by cerebellar infarction is relatively normal, but if nausea and vomiting occur elsewhere, it is crucial to determine the specific cause, and sometimes surgical treatment may be necessary. (Please use medications under the guidance of a professional physician; do not self-medicate.)
