What Is Psoriasis

Psoriasis is a chronic autoimmune skin condition characterised by the rapid buildup of skin cells. It causes red, scaly patches on the skin that can be itchy, painful, and aesthetically bothersome. Psoriasis is a non-contagious condition that affects around 2-3% of the global population.

The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic factors, immune system dysfunction, and environmental triggers. The immune system mistakenly activates the skin cells, causing them to multiply rapidly and build up on the surface of the skin. This excessive cell turnover cycle results in the formation of raised, thickened areas of skin called plaques.

The most common type of psoriasis is called plaque psoriasis, which presents as red, inflamed patches covered with silvery-white scales. These patches can appear anywhere on the body, but they are most commonly found on the elbows, knees, scalp, and lower back. Other types of psoriasis include guttate psoriasis, inverse psoriasis, pustular psoriasis, and erythrodermic psoriasis, each with its own distinct characteristics.

Psoriasis is known to have a genetic component, as it often runs in families. Additionally, certain triggers can worsen the condition or lead to flare-ups, including stress, infections, injuries to the skin, certain medications, hormonal changes, and environmental factors.

While there is no cure for psoriasis, various treatments can help manage and control the symptoms. Topical treatments such as corticosteroids, retinoids, and moisturisers can help reduce inflammation and alleviate itching. For more severe cases, phototherapy, which involves exposure to ultraviolet light, or systemic medications such as oral or injectable immunosuppressants may be prescribed.

Managing psoriasis also involves lifestyle modifications, such as avoiding triggers, practicing good skincare, and maintaining a healthy lifestyle. This includes keeping the skin moisturised, avoiding harsh soaps and irritants, managing stress levels, maintaining a balanced diet, and avoiding smoking and excessive alcohol consumption.

Psoriasis is a chronic condition that requires long-term management, and its impact extends beyond the physical symptoms. It can affect an individual’s emotional well-being, self-esteem, and overall quality of life. Support from healthcare professionals, patient education, and connecting with support groups or counselling services can be beneficial in coping with the challenges of living with psoriasis.
