Have you ever seen someone with a nose that appear to be bloated and reddish? I guess you haven’t seen yet one, but if you have seen one, that person might be suffering from a disease called “rosacea.” Rosacea is a skin condition that lasts for a very long period. It is generally characterized by superficial blood vessels that are dilated, and papules, swelling, and pustules. The cause of rosacea is still unknown, but there are risk factors that may be contributory to the onset of the disease. The onset of rosacea doesn’t choose any time or any person. A person may suffer from such malady even at the very early years of his/her life. Moreover, there are basically four different types of rosacea, and these types are usually based on certain characteristics of the disease.  The first three types of this disease generally afflict the human skin. The last type however usually infects the human eye and it is called “ocular rosacea.” This disease usually afflicts women more than men, and it also generally affects those who are in their thirties up to those who are in their fifties. Furthermore, this disease generally afflicts those who are Caucasians. The Symptoms of Rosacea The “Curse of Celts,” as this disease is usually referred to, has various symptoms. The primary symptoms of this disease include those of the small and dilated blood vessels, broken capillaries face, redness, papules, swelling, and pustules. Broken Capillaries are the most obvious symptoms of rosacea. The disease may not need therapy but if the disease has been full-blown or is already affecting the social life of a person, then it should be treated. Causes of Rosacea The causes of rosacea is definitely unknown. It may be genetically programmed or is due to genetic predisposition, or it may be caused by some trigger factors. Triggers are those factors that may cause flushing or blushing. Other triggers include those of heat from sunlight, extreme temperatures, severe sunburn, strenuous exercise, anxiety, change of temperature, and stress. Medications can also cause the onset of such disease, and may cause flare up of rosacea. Use of medications such as those of steroids, dosages of benzoyl peroxide, and even tretinoin can cause the flaring up of rosacea. Studies on cathelicidins have shown that patients that exhibit rosacea are usually found to have high level of cathelicidin. Hence, it is necessary to inhibit the level of cathelicidin to assuage the effects of rosacea. Another correlation that may have a bearing on the onset of rosacea is that of the level of demodex mites. It is found that those who are suffering from rosacea have high level of mites. Another factor that is worth considering is the relationship between rosacea and intestinal bacteria. Rosacea patients are found to have higher concentration of intestinal bacteria, and this overgrowth of intestinal bacteria may play a role in the flaring up of rosacea. An effective treatment of rosacea, therefore, necessitates a clear understanding of the risk factors and trigger factors that may instigate the onset of rosacea flare-ups. It is critical that a patient is aware of these factors so that he/she could mitigate or assuage the impact and symptoms of this disease.
