The usual causes of headache
Optical defects (myopia, hypermetropia, and astigmatism) and presbyopia, when insufficiently or inadequately corrected by spectacles, contact lenses or refractive surgery, are the most frequent causes of headache.
Insufficient coordination between the eyes is equally a frequent cause of headache.
High eye pressure, inflammations of the cornea, iris, corpus ciliaris and of the eye fundus are other relatively frequent causes of headache.
Consult your eye doctor in order to exclude these diseases.
Headache can also be due to various food additives (especially in black chocolate, blue cheese, white wine, glutamate and glutaraldehyde), irregular or insufficient meals (especially in weight loss diet), constipation, insufficient duration or quality of sleep and after coïtus.
Fluctuations in the arterial tension, hormonal troubles, excess of analgesics, parasites in the bowel (see your family doctor), sinusitis (see your nose, throat and ear specialist), dental problems (see your dentist) and neurological troubles (see your neurologist) are other frequent causes of headache.
