What is psoriasis?
Psoriasis is a chronic skin condition that causes skin cells to multiply faster than normal. This leads to red, scaly patches on the skin that can be itchy and sometimes painful. While the exact cause is still not fully understood, it’s believed to involve an immune system
Who gets psoriasis?
Psoriasis can affect anyone, regardless of age, gender, or ethnicity. However, it tends to appear in people aged 15 to 35. Family history plays a significant role; if someone in your family has psoriasis, you may be more likely to develop it. Stress, infections, and certain medications can also trigger flare-ups
Types of psoriasis
There are several psoriasis types, each with its own characteristics:
- Plaque psoriasis: This is one of the most common psoriasis types, affecting about 80-90% of people with psoriasis. It appears as raised, red patches covered with thick, silvery scales. These patches can appear anywhere on the body but are often found on the elbows, knees, and scalp.
- Scalp psoriasis: Usually the initial presentation(symptom) of psoriasis, and almost 80 % of psoriasis patients will eventually experience it. It is a chronic autoimmune illness characterized by erythematous, well-defined skin covered with thick scales, which are often silvery white
- Guttate psoriasis: Often starts in childhood or young adulthood, this type presents as small, drop-shaped spots on the trunk, arms, legs, and scalp. It can be triggered by bacterial infections, such as strep throat.
- Inverse psoriasis: This type occurs in skin folds, such as under the breasts, in the groin, or under the armpits. It appears as bright red, shiny lesions and is often irritated by friction and sweating.
- Pustular psoriasis: Characterized by white pustules (blisters of noninfectious pus) surrounded by red skin, this type can be localized (affecting specific areas) or generalized (covering most of the body).
- Erythrodermic psoriasis: This is a rare and severe form that can cover the entire body with a red, peeling rash that can itch or burn intensely. It requires immediate medical attention.
The predominant type of psoriasis is plaque psoriasis, affecting the majority of people with the condition. It can vary in severity, from small patches to widespread areas covering large parts of the body. Treatment options include topical treatments, phototherapy, and systemic medications.
