Psoriasis, a chronic autoimmune skin condition, affects millions of people worldwide. Over the years, the number of psoriasis cases has been steadily increasing, creating a significant burden on individuals and healthcare systems.
Understanding the factors behind this rise is crucial in developing effective prevention and management strategies. In this article, we will shed light on the culprits behind the rise of psoriasis cases.
1. Genetic Predisposition
Genetics play a significant role in psoriasis. If you have a family history of the condition, you are more likely to develop it yourself.
Studies have identified several gene variations associated with psoriasis, particularly those involved in the immune system and skin cell proliferation. However, genetic predisposition alone does not explain the increasing prevalence of psoriasis, indicating that other factors are at play.
2. Environmental Triggers
Psoriasis can be triggered or exacerbated by various environmental factors. One such trigger is stress, which can disrupt the immune system and worsen inflammation.
Other triggers include infections, specifically streptococcal infections, which activate the immune system and lead to psoriasis flare-ups.
Exposure to certain medications, such as beta-blockers, lithium, and antimalarial drugs, can also trigger psoriasis in individuals with a genetic susceptibility.
Additionally, cold weather, dry air, and lack of sunlight can contribute to the development or worsening of psoriasis symptoms.
3. Obesity and Metabolic Syndrome
Obesity and metabolic syndrome (a cluster of conditions including high blood pressure, high blood sugar levels, excess body fat around the waist, and abnormal cholesterol levels) have been linked to an increased risk of psoriasis.
The exact mechanism behind this association is not fully understood, but it is believed that chronic inflammation and insulin resistance play a role in the development and severity of psoriasis.
4. Smoking and Alcohol Consumption
Both smoking and excessive alcohol consumption have been identified as risk factors for psoriasis. Smoking not only increases the likelihood of developing psoriasis but also worsens its severity and reduces the effectiveness of treatment.
Alcohol, particularly in heavy drinkers, can trigger psoriasis flares and interfere with medications used to manage the condition.

5. Hormonal Influences
Hormonal changes have been observed to impact the development and severity of psoriasis. Women often experience changes in their psoriasis symptoms during pregnancy and menopause, indicating the influence of hormones.
Additionally, certain hormonal disorders, such as thyroid dysfunction, may contribute to the development or worsening of psoriasis.
6. Western Diet
The modern Western diet, which is typically high in processed foods, sugar, and unhealthy fats, has been associated with various health conditions, including psoriasis.
Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins has been found to have a protective effect against psoriasis, while a diet high in processed foods and unhealthy fats may promote inflammation and worsen symptoms.
7. Vitamin D Deficiency
Vitamin D, often referred to as the “sunshine vitamin,” plays a crucial role in maintaining immune system function and skin health.
Deficiency in vitamin D has been linked to an increased risk of psoriasis and may also contribute to the severity of the condition. The prevalence of vitamin D deficiency is higher in regions with limited sunlight exposure, which may partially explain the higher incidence of psoriasis in these areas.
8. Mental Health and Quality of Life
Psoriasis is not simply a physical condition; it also takes a toll on mental health and overall quality of life.
The chronic nature of psoriasis, coupled with its visible symptoms, can lead to feelings of embarrassment, self-consciousness, and depression. Individuals with psoriasis may experience social stigma, discrimination, and reduced self-esteem, which can further contribute to psychological distress.
9. Pollution and Environmental Factors
Recent research suggests that pollution and certain environmental factors may contribute to the increasing prevalence of psoriasis.
Air pollution, specifically fine particulate matter and volatile organic compounds, has been found to trigger inflammation and worsen psoriasis symptoms. Exposure to chemicals commonly found in everyday products, such as cleaning agents and personal care items, may also play a role.
10. Lack of Proper Treatment and Awareness
Despite significant advancements in psoriasis research and treatment, many individuals remain undiagnosed or undertreated.
The lack of awareness among both the general public and healthcare professionals leads to delayed diagnosis and suboptimal management. Improving education and access to appropriate treatments is crucial in reducing the burden of psoriasis worldwide.
