What Causes Plaque Psoriasis? Here's What Doctors Need You To Know
Plaque psoriasis is a common condition that affects more than 60 million of people worldwide. According to the National Psoriasis Foundation, approximately 8 million people in the United States have psoriasis, and 30% of them have plaque psoriasis, making it the most common form of psoriasis. There are many causes to keep in mind, If you start searching the options, you can find the most surprising ones.
Genetics
Genetics is a significant factor in the development of plaque psoriasis. According to a study published in the Journal of Investigative Dermatology, genetics account for approximately 80% of the risk for developing psoriasis. Researchers have identified over 60 genes associated with psoriasis, many of which are involved in the immune system and skin development.
Environment
Environmental factors such as stress, injury to the skin, and infections can trigger the onset of plaque psoriasis or exacerbate existing symptoms. According to the National Psoriasis Foundation, 50% of people with psoriasis report that stress triggers or worsens their symptoms.
Lifestyle
Lifestyle factors such as smoking and excessive alcohol consumption can also contribute to the development of plaque psoriasis. According to a study published in the Journal of the American Academy of Dermatology, smokers are almost twice as likely to develop psoriasis compared to non-smokers. The study also found that the risk of developing psoriasis increased with the number of cigarettes smoked per day.
Medications
Certain medications can trigger or worsen psoriasis symptoms in some people. According to the National Psoriasis Foundation, medications that may worsen psoriasis symptoms include lithium, beta-blockers, antimalarial drugs, and non-steroidal anti-inflammatory drugs (NSAIDs).
Obesity
Obesity is also a risk factor for plaque psoriasis, particularly in women. According to a study published in the Journal of Investigative Dermatology, women with a body mass index (BMI) of 30 or higher had a 63% increased risk of developing psoriasis compared to women with a BMI of less than 25.
Deficiencies
Vitamin D deficiency may also play a role in the development of plaque psoriasis. According to a study published in the Journal of the American Academy of Dermatology, people with psoriasis may have lower levels of vitamin D compared to people without psoriasis. However, more research is needed to fully understand the relationship between vitamin D and psoriasis.
In conclusion, plaque psoriasis is a complex condition that is caused by a combination of genetic, immune, environmental, and lifestyle factors. While it cannot be cured, plaque psoriasis can be managed with a range of treatment options. It's important to seek medical advice from a healthcare professional who can provide an accurate diagnosis and recommend appropriate treatment options.
