Psoriasis

Usually, skin cells regenerate every 28 to 30 days. With psoriasis, the immune system goes into overdrive causing new skin cells to be produced every three to four days. As these new skin cells move to the skin’s surface they build up to form plaques. Why the immune system behaves in this way isn’t fully understood.

The condition can run in families but the role of genetics as a possible cause of psoriasis is unclear. Psoriasis is not contagious. 

A number of factors can trigger psoriasis flare-ups:

• stress
• skin injuries
• illnesses and infections
• some medications, like lithium and beta-blockers
• cold, dry weather
• sun damage
• certain foods
• smoking 
• heavy drinking

Psoriasis is diagnosed by examining the skin. In some cases, a small biopsy or swab may be done to confirm a diagnosis and check for infection. 

There are several treatments available to relieve symptoms: 

• topical treatments – Over-the-counter and prescription treatments like corticosteroids, coal tar, hydrocortisone, salicylic acid and heavy cream, ointment, or oil moisturisers can be applied directly to the skin to reduce itching, scaling and irritation
• phototherapy – If topical treatments aren’t effective or if the psoriasis is severe, light treatments may be used with the aim of slowing down the growth of skin cells
• oral or injected medications – Oral or injected medication may be tried in cases where topical treatments and light therapy are unsuccessful, or if the condition is particularly severe or widespread. These treatments aim to calm the immune response that causes accelerated skin growth to help reduce redness, scales and irritation

Why have I suddenly got psoriasis?

While what causes the immune system to go into overdrive isn’t fully understood, the sudden development of psoriasis is thought to be due to a combination of genetic predisposition and environmental triggers such as infections, skin injuries, stress, certain medications, and smoking.

Can psoriasis spread by scratching?

While scratching does not cause psoriasis to be spread from person to person, it can cause injury to your skin, which may worsen your symptoms or cause the condition to spread to previously unaffected areas of skin. This is known as the Koebner phenomenon. 

Can psoriasis cause hair loss?

When psoriasis affects the scalp, it can cause hair loss. This is due to a combination of inflammation in the skin, which causes the hair follicles to become weak and brittle, and scratching due to the itchy, dry plaques. 

What does psoriasis look like when it starts to heal 

As psoriasis plaques begin to heal, you’ll likely notice that your skin feels less itchy and is less flaky. You may also see a reduction in redness and a more even skin tone.
