Rosacea Risk Factors:
Researchers have suggested several factors that may be related to the development of rosacea:
- A disorder of the blood vessels that causes them to swell, leading to flushing.
- A genetic predisposition combined with certain environmental factors that may irritate the skin.
- Clogging of the sebaceous gland openings with skin mites called Demodex folliculorum, which live in facial-hair follicles.
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 may be somewhat 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.
Any one of the following warning signs can be a signal to see a dermatologist or other knowledgeable physician for diagnosis and appropriate treatment of rosacea before the signs and symptoms become increasingly severe:
- Redness on the cheeks, nose, chin or forehead.
- Small visible blood vessels on the face.
- Bumps or pimples on the face.
- Watery or irritated eyes.
