Patients with migraines often experience significant nausea and vomiting, which is also an important diagnostic criterion in the diagnosis of migraines. The reason migraines cause nausea is primarily due to abnormalities in the trigeminal ganglion of migraine sufferers. These impulses may be transmitted to the solitary nucleus in the brainstem, which is mainly responsible for some autonomic nerves and closely related to vomiting. When the solitary nucleus is affected, obvious vomiting naturally occurs. Many migraine patients find that their symptoms are somewhat relieved after vomiting. The main treatment for migraine-induced vomiting is to have the patient rest quietly and take appropriate pain relief medication. If vomiting is pronounced, it is recommended that the patient take antiemetic drugs orally, preferably by muscle injection, which generally provides quick symptom relief.
