Plaque psoriasis is a chronic autoimmune condition characterized by the rapid growth of skin cells leading to raised, red patches covered with silvery scales.

Main Causes of Plaque Psoriasis

Plaque psoriasis can be attributed to various factors that interact with each other.

1. Genetic Factors

• Family History: Individuals with a family history of psoriasis are more likely to develop the condition.
• Genetic Mutations: Certain gene mutations, such as those in the PSORS1 gene, have been linked to psoriasis.

2. Immune System Dysfunction

• Autoimmunity: The immune system mistakenly attacks the skin cells, resulting in overproduction.
• Inflammation: Cytokines released during inflammation contribute to the skin cell proliferation associated with psoriasis.

3. Environmental Triggers

• Infections: Conditions like strep throat can trigger flare-ups.
• Stress: High stress levels can exacerbate symptoms.
• Weather: Cold, dry weather may lead to outbreaks.

4. Lifestyle Factors

• Obesity: Increased body weight can worsen psoriasis symptoms.
• Smoking: Smoking is a known aggravator of psoriasis.
• Alcohol Consumption: Excessive alcohol intake can increase the risk of flare-ups.
