What are the Possible Causes of Headache and Nausea?
Headache with nausea is usually known as a migraine headache. And the cause behind this type of health condition is unknown. Some health professionals speculate that serotonin has something to do with the cause of migraine headaches. Moreover, serotonin has effects on the blood vessels — for instance, when serotonin levels are high, this causes the blood vessels to shrink.
On the other hand, when serotonin levels become low the blood vessels will start to swell. Once swelling happens to the blood vessels a person will start to feel pain.
Another possible cause of headache with nausea is hereditary causes. There have been studies that show a connection between genes and headache and nausea. According to the American Migraine Foundation, if one parent experiences migraines then there is a 50% possibility that their child will get migraines as they age as well. Meanwhile, there is a 75% probability if both parents experience migraines.
Lastly, research has shown that women are much more susceptible to headache with nausea due to hormonal fluctuations. Women experience hormonal fluctuations during their period, pregnancy, and menopause.
