Causes and Triggers

In individuals with plaque psoriasis, the immune system mistakenly attacks healthy skin cells, prompting an overproduction of new cells. This rapid turnover leads to the accumulation of dead skin cells on the surface, forming the characteristic plaques. Several factors may trigger or exacerbate this condition, including:

• Genetics: A family history of psoriasis increases the likelihood of developing the condition.
• Infections: Certain infections, particularly streptococcal throat infections, have been linked to the onset or worsening of psoriasis. niams.nih.gov
• Medications: Some drugs, such as beta-blockers and lithium, can trigger or aggravate psoriasis symptoms. mountsinai.org
• Lifestyle Factors: Stress, smoking, and heavy alcohol consumption are known to influence the severity and frequency of flare-ups. webmd.com

Symptoms

The primary symptom of plaque psoriasis is the appearance of raised, inflamed, and scaly patches on the skin. These plaques can be itchy, painful, and may crack or bleed. The severity of symptoms varies among individuals, ranging from minor localized patches to extensive coverage affecting large areas of the body.

Treatment Options

While there is currently no cure for plaque psoriasis, various treatments aim to manage symptoms and reduce flare-ups:

• Topical Treatments: Creams and ointments containing corticosteroids or vitamin D analogs are commonly prescribed to reduce inflammation and slow skin cell growth.
• Phototherapy: Controlled exposure to ultraviolet light can help diminish plaques in some individuals.
• Systemic Medications: For moderate to severe cases, oral or injectable medications that affect the entire body may be utilized.
• Biologic Therapies: These newer treatments target specific parts of the immune system and have shown promise in managing symptoms.

It’s essential for individuals with plaque psoriasis to consult with a healthcare provider to determine the most appropriate treatment plan based on the severity of their condition and overall health.

Understanding the causes and triggers of plaque psoriasis is crucial for effective management. By identifying and avoiding specific triggers, adhering to prescribed treatments, and making lifestyle adjustments, individuals can achieve better control over their symptoms and improve their quality of life.
