Nausea can occur as a premonitory symptom of headache, regardless of the pain and headache is often accompanied by nausea and hypersensitivity to external stimuli. Headache is a localized pain in any region of the head. Episodes of headache can be rare or affect several times a month and their frequency varies from person to person. Although the causes of headache are not fully known, genetic and environmental factors seem to be involved.

​

Women are three times more likely to have headache than men and the cause of this difference may be due to fluctuations in estrogen levels observed in women which seem to trigger headaches. In fact, women who often suffer from migraine often report having headaches immediately before or during the menstrual period, i.e. when they have a sharp drop in estrogen levels. Other women have a greater tendency to develop headache during pregnancy or menopause.

​

Skipping meals or fasting could cause headache and also some foods or food additives, such as the sweetener aspartame and the preservative monosodium glutamate, found in many foods, can cause headaches. Stress can also cause headaches.

​

Be aware that certain drug treatments for headaches can cause health problems; for example, taking pain medications, such as aspirin, can cause or aggravate gastritis or stomach ulcers, especially if these medications are taken in high doses or over a long period of time.
