Psoriasis
Understanding Psoriasis
Psoriasis is an autoimmune disease that causes an itchy rash with scaly patches on the scalp, nails, and joints like the elbows and knees. The condition can have a significant impact on quality of life, but with the right care it can be managed effectively.
Psoriasis normally causes flaky patches of skin, but other common symptoms can include dry, cracked skin that may bleed, or swollen and stiff joints. Flare-ups can be triggered or worsened by stress, skin injury, and infection.
Types of Psoriasis
Plaque Psoriasis
The most common type, causing red, dry and scaly patches on the elbows, knees, scalp and lower back.
Nail Psoriasis
Affects fingernails or toenails, causing abnormal nail growth and discolouration. In severe cases, nails may detach from the nail bed or crumble.
Guttate Psoriasis
Appears as small, pink spots on the skin and is usually triggered by a bacterial infection.
Inverse Psoriasis
Affects the skin folds of the armpits, groin, buttocks and breast. It may worsen due to friction or sweating.
Pustular Psoriasis
Less common, characterised by the formation of pus-filled blisters on the skin.
Erythrodermic Psoriasis
A rare but severe form that can cause widespread redness and scaling across the entire body.
Treatment Options for Psoriasis
While there is no known cure for psoriasis, a variety of treatments can help manage the symptoms and improve quality of life. Options may include:
Topical Treatments
The initial treatment method for most patients. Creams, ointments, and shampoos are applied directly to the affected skin areas.
Phototherapy
Ultraviolet light is used to slow down the growth of skin cells.
Oral Medications
Methotrexate or cyclosporine are medications that help suppress the overactive immune response.
