Triggers Affecting the Occurence of Rosacea

Several factors have been identified that may be related to the development of rosacea:
~A disorder of the blood vessels that causes them to swell, leading to flushing may be a factor in rosacea.

~A genetic predisposition combined with certain environmental factors that may irritate the skin causing rosacea symptoms to occur.

~Clogging of the sebaceous gland openings with skin mites called Demodex folliculorum, which live in facial-hair follicles are thought by some to be a factor in the presence of rosacea.

~Rosacea appears to affect fair-skinned people more often, though it can affect any skin type. Often several people in a family have rosacea, so researchers think it may be at least partly genetic.

~Rosacea by the numbers may be more common in women, but is often more severe in men -- perhaps because men tend to delay seeking medical help until rosacea reaches advanced stages.

~Other factors that may be involved include vitamin-B deficiency, local infection, hydrochloric-acid (stomach acid) deficiency, infection with Helicobacter pylori, and/or digestive disorders.

~In some cases, rosacea may be associated with migraine headache, other skin disorders, and certain eye disorders, including blepharitis and keretitis.
