The precise cause of psoriasis is unknown, but some factors which play a role in the development or progression of psoriasis include: (read more)
Heavy alcohol consumption
Family history (genetics)
A bacterial or viral infection may trigger a psoriasis flare up, especially in children. In people with guttate psoriasis, a strep infection usually precedes the onset.Interestingly, certain pathogenic bacteria are found on the skin of psoriasis patients, and when treated with antibiotics, the psoriasis has been shown to subside in most of these patients.
Pathogenic organisms that have been associated with psoriasis include:
Malassezia ovalis (also found in seborrheic eczema)
Gluten sensitivity may also play a role in the development of psoriasis. A high prevalence of gluten sensitivity has been found in people with psoriasis. In these individuals, a gluten-free diet was found to decrease psoriasis flare ups.Gluten sensitivity has been associated with many other diseases, which illustrates the far-reaching negative effects of a condition that begins in the gut.
Poor digestion or, specifically, poor protein digestion, may contribute to the development of psoriasis. When proteins are not broken down and absorbed properly, they remain in the digestive tract and are, instead, broken down by bacteria in the bowel. The breakdown products, or polyamines, have been found to be increased in psoriasis patients. Psoriasis has also been shown to improve when polyamine levels are decreased.
In addition to polyamine toxins, other gut toxins, such as bacterial toxins and Candida toxins, can influence the rapid regeneration of skin cells that is seen in psoriasis.This is yet one more gut-skin connection. A low-fiber diet contributes to the buildup of these toxins. Fiber binds toxins, and helps move them out of the bowel before they have a chance to cause harm. Toxins can also contribute to gut inflammation, which has been found in people with psoriatic arthritis.
The bowel toxins mentioned above create a toxic environment in the bowel which can create a condition called leaky gut, or increased intestinal permeability. Leaky gut is due to inflammation of the intestinal lining which allows for the passage of larger than normal particles through the intestine. When this occurs, toxins are absorbed into the bloodstream and travel to the liver where they are then detoxified. The toxins are easily absorbed through a leaky gut. Leaky gut has been found to be more prevalent in people with psoriasis than in healthy individuals.If the liver is overburdened, many of these toxins will go directly into the bodys circulation and cause exaggerated immune responses,particularly in genetically susceptible people.
Optimal liver detoxification is increasingly difficult in todays world where chemicals are virtually impossible to avoid. Some naturopathic doctors view psoriasis as the result of the body releasing toxins through the skin because of this overexposure to toxins and the inability of the liver to detoxify them.
It is interesting that heavy alcohol consumption, which imposes a large burden on the liver, is known to be associated with psoriasis.This further illustrates the important role that liver detoxification plays in maintaining health. Similarly, smoking is also linked to psoriasis.This may be due to the increased toxic burden placed on the body by the many chemicals in cigarette smoke.
Stress also contributes to psoriasis. Not only does stress increase itching and worsening of psoriasis,but the psoriasis itself increases stress because of how it affects appearance and ones self-perception. This can create a vicious cycle that makes healing difficult.
Some medications can trigger a psoriasis reaction. Beta blockers, lithium, antimalarial drugs, ACE inhibitors and nonsteroidal anti-inflammatory drugs (NSAIDs) can all activate or worsen psoriasis.
Genetics also plays a role in psoriasis in combination with the environmental factors. About 40 percent of people with psoriasis have a family member with the disorder.
