What causes nausea during a headache? See what the doctor says

Headaches are accompanied by projectile vomiting. Every time a headache occurs, even taking medicine is a luxury. This is something many headache patients cannot understand. Why do headaches also cause vomiting? Are they two different diseases?

Vomiting is more uncomfortable than headache. For women, vomiting is very common, but this type of vomiting is usually controllable. The discomfort of migraine vomiting is several times that of ordinary vomiting. When a headache occurs, some patients will vomit out the medicine even if they take it quickly, and they cannot achieve any analgesic or antiemetic effect. Because vomiting is a symptom of headache, not a disease, why do you want to vomit when you have a headache? There are mainly the following points.

1. Interaction of the nervous system

During a migraine attack, deep brain structures are activated. Pain-sensitive nerve fibers can be activated through the release of sensitized vasoactive substances from the trigeminal nerve endings or the efferent nerve activity of the parasympathetic nerves. After activation, the nerves are extremely excited, and the vomiting center is also activated. If the headache cannot be stopped, the vomiting center will continue to be activated, and vomiting will continue, causing gastrointestinal dysfunction until the headache is relieved and the vomiting will also be relieved.

2. Vomiting is just a symptom

Vomiting is caused by headache, and vomiting can also cause headache. Vomiting caused by headache is a secondary symptom, that is, vomiting is caused by headache. At this time, we only need to control the headache through some non-oral medications, and the vomiting will gradually disappear.

3. Give you a warning

Some headache patients will feel stomach discomfort before the headache. At this time, they should take medicine in time to suppress the onset of headache, and the vomiting feeling will stop. Vomiting is very uncomfortable. Everyone has experienced vomiting more or less. Among them, migraine patients vomit more frequently and feel more uncomfortable. It is recommended that when a headache occurs, if there is only a feeling of vomiting, take analgesics and antiemetics as soon as possible. If it is projectile vomiting, then only intravenous antiemetic drugs can be used and oral analgesics can be taken. For such patients, more effective treatment plans should be sought, rather than simply staying in the aspects of antiemetic and analgesia.
