Causes of Rosacea


causes of rosaceaThe real cause of rosacea is still not known and remains a mystery until today. There are however a lot of theories underlying the causes of rosacea although they aren’t scientifically proven yet. It is hoped that the continuing research in this area will lead to improved management, prevention as well as treatment of rosacea. One of such theories believes that it is a vascular disorder because it is associated with visible blood vessels and flushing redness. Some doctors argue that this flushing involves the nervous system because this condition is caused and aggravated when one is under stress.

It is also believed that the improved flow of blood during the flushing usually leads to an raise in tissue fluid, which builds up faster than it can be removed by the lymphatic system. The swelling further contributes to skin condensing as the tissue build up. Away from the vascular factors it is also believed that presence of Demodex folliculorum a microscopic mite also causes rosacea.

This mite is normal and normally feeds on cast off body cells, it has however been found to be in abundance in people suffering from rosacea. A bacterium referred to as Helicobacter pylori that causes duodenal ulcers is also believed to cause rosacea, conceivably by increasing gastrin levels thus stimulating flushing.

Other factors that are believed to trigger and aggravate rosacea or trigger flushing include embarrassment, fear, stress or anxiety. A outbreak can also be caused by change in weather conditions such as string winds as well as change in humidity. Direct exposure to sun is also associated with rosacea. Other factors that trigger rosacea include consumption of alcohol, strenuous exercise, corticosteroids, hot baths, and saunas, certain medications, eating spicy foods, hot food and beverages, emotional upsets. It’s no wonder that a lot of people notice flares during holidays especially Christmas.

Some researchers also argue that rosacea is a hereditary condition, it has been noted that people from families that have a history of rosacea have a higher risk of developing this condition in life. Factors than increase the blood flow to your skin surface don’t cause but aggravate rosacea.

These factors include drinking alcohol which basically leads to flushing of your skin thus aggravating rosacea. You are more likely to suffer from this condition if you have a lighter eye and hair color, experience frequent blushing or flushing and if you’re in the age bracket of 30 to 60 particularly women in their menopause.

When this condition develops, it may appear, fade away and then recur, although your skin may fail to return to its original color and dilated blood vessels as well as acne appear. It is very rare for this condition to reverse itself and when it develops it may last for a couple of years and if not treated it gradually worsens. However, there is no call for panic because if diagnosed early the symptoms associated with it can be relived. Avoiding most of the above mentioned causes will greatly help you reduce the risk of developing rosacea.
