Psoriasis is a chronic skin condition that affects millions of people worldwide. It occurs when the immune system mistakenly attacks healthy skin cells, causing them to grow faster than normal and form thick, scaly patches called plaques.

Psoriasis can affect any part of the body, but it is most common on the elbows, knees, scalp, and lower back. There are different types of psoriasis, each with its symptoms and appearance. The most common type is plaque psoriasis, which accounts for about 80% to 90% of cases.

Other types include guttate psoriasis, which causes small, drop-shaped spots; inverse psoriasis, which affects the skin folds; pustular psoriasis, which causes pus-filled blisters; erythrodermic psoriasis, which covers most of the body with red, peeling skin; and nail psoriasis, which affects the fingernails and toenails.

The symptoms of psoriasis can vary from person to person, but some common ones are red patches with thick, silvery scales that itch or burn; Dry, cracked skin that may bleed; Thick, ridged, or pitted nails; and Swollen or stiff joints (in some cases).
Psoriasis can also affect the quality of life of people who have it. It can cause physical discomfort, emotional distress, social stigma, and reduced self-esteem. Psoriasis can also increase the risk of other health problems, such as cardiovascular disease, diabetes, obesity, and depression.
Psoriasis is not contagious or infectious. It is not something to be ashamed of or hide from others. People with psoriasis can lead fulfilling and productive lives with proper treatment and care. They can also find support and information from various sources, such as their doctor, dermatologist, pharmacist, nurse, psychologist, family members, friends, online communities, or organizations dedicated to psoriasis awareness and research.
