What is psoriasis?
Psoriasis is a chronic inflammatory skin disease that presents with red scaly patches on the scalp, body, and limbs. It is a non-infectious disease that affects all races regardless of age.
The commonly affected areas are the elbows, knees, and scalp. Nail changes such as pits in the nail plate and separation of the nail from the nail bed are seen in some patients.
Joints may also be affected, resulting in joint pain and swelling. Although the disease can occur at any age, it typically starts for people in their 20s. It is also estimated that 1 to 2 per cent of the general Singapore population have psoriasis.
What is the cause?
There is no single cause for psoriasis, although studies have pointed towards genetic links. However, there are certain factors known to make the condition worse.
Stress, infections, and some medications can aggravate the condition. Once psoriasis starts, there may be periods of remission with periods of active psoriasis.
Trigger factors include
- Physical, emotional, and mental stress
- Injury to the skin caused by scratching, peeling, cuts, rubbing, injuries, or even sunburn
- Infection of the chest, throat, and urinary tract
- Oral medications such as beta-blockers, anti-malarials, lithium
- Obesity, alcohol abuse, and smoking
Common symptoms
- Red rashes on the scalp or other localised areas on the body (e.g elbows)
- Joint pain and swelling
- Changes in the nail texture or “pitting”
Treatment options
- Topical creams or ointments
- Phototherapy
- Oral medications
- Injection therapy with biologics
Living with psoriasis
- Learn to cope with stress
- Take care of yourself, avoid falling ill with throat infections, stay hydrated, and have plenty of rest
