What Causes Psoriasis?

Psoriasis is a complex autoimmune disease where the immune system mistakenly attacks healthy skin cells, leading to an accelerated production of skin cells. This causes the cells to build up on the surface of the skin, forming the characteristic red, scaly patches. While the exact cause of psoriasis is not fully understood, genetics play a significant role. If you have a family history of psoriasis, you are more likely to develop the condition. Environmental factors such as infections, stress, skin injuries, and certain medications can also trigger or worsen psoriasis symptoms.

Is Psoriasis Contagious?

No, psoriasis is not contagious. You cannot catch psoriasis by touching someone who has it or by coming into contact with their skin. Psoriasis is a result of internal immune system activity, and it does not spread from person to person. This misconception often leads to stigma, but it’s important to understand that psoriasis is a chronic condition that affects the individual’s immune system, not something that can be passed on to others.

What Are The Different Types Of Psoriasis?

There are several types of psoriasis, each with its own unique symptoms:

  • Plaque Psoriasis: The most common form, characterized by raised, red patches covered with silvery-white scales.
  • Guttate Psoriasis: Often triggered by infections, this type appears as small, drop-shaped lesions.
  • Inverse Psoriasis: Occurs in skin folds, causing smooth, red patches that can be irritated by sweating and friction.
  • Pustular Psoriasis: Involves white pustules surrounded by red skin, usually on the hands and feet.
  • Erythrodermic Psoriasis: A severe, inflammatory form that can cover large areas of the body with a red, peeling rash.

How Is Psoriasis Diagnosed?

Psoriasis is typically diagnosed by a dermatologist based on the appearance of the skin. During a physical examination, the doctor will look at the affected areas and may ask about your medical history, including any family history of psoriasis. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other skin conditions. Since psoriasis can resemble other skin diseases, an accurate diagnosis is crucial for determining the most effective treatment.

Can Psoriasis Be Cured?

There is currently no cure for psoriasis, but there are many effective treatments available that can help manage symptoms and reduce flare-ups. Treatments range from topical creams and ointments to phototherapy and systemic medications. The goal of treatment is to reduce inflammation, slow down the rapid production of skin cells, and manage symptoms like itching and scaling. Many people with psoriasis find that with the right treatment plan, they can lead a normal, comfortable life. However, since psoriasis is a chronic condition, ongoing management is often necessary.
