Psoriasis: Not just about the skin
Psoriasis is fairly common globally as well as in Bangladesh. Although the condition is classified as a dermatological disease, it doesn't start in the skin, and its damage is also not limited there.
The disorder causes skin cells to multiply up to 10 times faster than normal. This makes the skin build up into bumpy red patches with white scales. They can grow anywhere. But most common places where such bumps are developed are the scalp, elbows, knees, and lower back.
Psoriasis is not contagious. But it can be hereditary. It is thought to be an immune system problem that causes the skin to regenerate faster than normal.
Just what causes the immune system to malfunction isn't entirely clear. Researchers believe both genetics and environmental factors play a role. Factors like stress and smoking can increase one's risk of developing psoriasis.
Complications associated with psoriasis include psoriatic arthritis, which causes pain, stiffness and swelling in and around the joints; eye conditions such as conjunctivitis; obesity; Type 2 diabetes; high blood pressure; cardiovascular disease; some autoimmune diseases; mental health conditions such as low self-esteem and depression.
Psoriasis cannot be completely cured. Treatment usually helps keep the condition under control. Treatments are determined by the type and severity and the area of skin affected.
Conventional treatments fall into 3 categories:
Topical -- creams and ointments applied to the skin.
Phototherapy -- skin is exposed to certain types of ultraviolet light.
Systemic -- oral and injected medications that work throughout the entire body.
Treatments are often used in combination.
