The exact cause of psoriasis is unknown, but it is believed to involve a combination of genetic and environmental factors.
Genetic Predisposition: People with a family history of psoriasis are at an increased risk of developing the condition.
Immune System Dysfunction: In psoriasis, the immune system mistakenly attacks healthy skin cells, leading to rapid skin cell growth and the characteristic symptoms.
Common Triggers
While not always predictable, certain factors can trigger psoriasis flare-ups:
Infections: Strep throat infections can trigger guttate psoriasis.
Stress: Emotional and physical stress can exacerbate psoriasis symptoms.
Injury to the Skin: Minor injuries, such as cuts, scrapes, or sunburn, can trigger psoriasis at the site of injury (the Koebner phenomenon).
Certain Medications: Some medications, such as beta-blockers and lithium, can worsen psoriasis symptoms.
Alcohol Consumption: Excessive alcohol consumption can trigger or worsen psoriasis flare-ups.
Smoking: Smoking is a significant risk factor for developing severe psoriasis and can increase the severity of existing symptoms.
Diagnosis and Treatment
Diagnosing psoriasis typically involves a thorough physical examination by a dermatologist. In some cases, a skin biopsy may be necessary to rule out other skin conditions.
Treatment for psoriasis focuses on managing symptoms and improving quality of life. While there is no cure, various treatment options are available, including:
Topical medications: Creams, ointments, and lotions containing corticosteroids, vitamin D analogs, or salicylic acid can help reduce inflammation and remove scales.
Light therapy: Exposure to ultraviolet (UV) light can slow skin cell growth and reduce inflammation.
Systemic medications: For moderate to severe psoriasis, systemic medications such as oral medications or injections may be prescribed to suppress the immune system.
Living with Psoriasis
