Patients with migraines may experience vomiting, which is one of the most common complications of migraines. The occurrence of vomiting in migraines is mainly because the headache may affect the vomiting center in the brainstem, such as affecting the solitary nucleus. Damage to the solitary nucleus can lead to gastrointestinal dysfunction and result in vomiting. Many patients find that their headache symptoms are alleviated after vomiting. In terms of treatment, on one hand, it is necessary to correct the occurrence of migraines, mainly by administering pain relief medications and allowing the patient to rest in a quiet environment. For vomiting, antiemetic medications can be given to the patient, either orally or by muscle injection. Most patients show significant clinical improvement after treatment. (Please use medication under the guidance of a doctor.)
