Common Rosacea Causes
Rosacea is a chronic skin disorder that principally affects the face and it is characterized by facial redness and pus-filled pustules. Some of these symptoms make this inflammatory skin condition to be mistaken for eczema or acne or any other skin allergy and hence making its treatment quite challenging. According to a recent research, it has emerged that approximately 1 in every 20 Americans are affected with rosacea.
Unfortunately, the symptoms that come with this skin condition worsen with time. It is for this reason that you should have perfect knowledge of some rosacea causes. However, it is important to mention that the exact cause of rosacea is not yet known but some health experts believe that it is caused by the following factors.
Abnormalities in facial blood vessels
This is one of the leading rosacea causes that dermatologists associate it with appearance of symptoms like persistent redness, flushing and visible blood vessels. However, researchers have not been able to establish what causes the abnormalities in facial blood vessels, it is still a mystery. Nevertheless, skin specialists believe that the damage to the skin collagen by sunlight is responsible for such abnormalities. This is because, exposure to sunlight causes dilation of skin blood vessels and hence the redness, thread veins and inflammation that accompany rosacea.
Helicobacter pylori bacteria
H. pylori is a bacteria found in the gut (digestive tract), it stimulates the production of a protein known as bradykinin. This protein causes the blood vessels to dilate. According to a recent study, Helicobacter pylori bacteria has been suggested by a number of dermatologists to be a possible cause of rosacea although the link is yet to be proven. Majority of experts believe that this bacterium plays a big role in the development of rosacea symptoms like flushing and skin redness.
Demodex folliculorum
This is a microscopic mite that lives on human skin and usually causes no health complications under normal conditions. However, research has shown that patients suffering from rosacea have high numbers of Demodex folliculorum. Therefore, it is true to say that these mites are usually harmless on human skin but their overpopulation causes or effects rosacea.
Genetics
Rosacea is one of the most common hereditary skin inflammatory condition. Basically, it runs in family’s history even though research has not yet confirmed the genes that are involved or how the disorder is passed on from one generation to another. Nevertheless, a recent research has revealed that up to 40 percent of patients with rosacea have close relatives with the condition as well. Unfortunately, this is one of the rosacea causes that’s unavoidable.
Chemicals and ingested agents
There are several chemicals and ingested agents that can trigger rosacea. Some of these include alcohol, hot beverages, caffeine, spicy foods and medicines such as topical steroids, amiodarone, oral steroids and high doses of vitamins B6 and B12. These chemicals and ingested agents contain certain triggers that make the symptoms associated with rosacea worsen. However, there is no sustainable evidence to support chemicals and ingested agents as rosacea causes. This can be due to the fact that not everyone is affected by some of these triggers.
