What Is Skin Disease Psoriasis?
Psoriasis is a chronic skin disease linked to an overactive immune system. It can cause skin cells to build up and form thick, scaly areas.
Psoriasis can affect people in different ways. Some people have small areas of affected skin, while others have symptoms over larger areas.
The American Academy of Dermatology and National Psoriasis Foundation provide information about psoriasis, its symptoms, triggers, and treatment.
Skin Disease Psoriasis Symptoms and Skin Problems
The psoriasis skin symptoms can vary from person to person. Common psoriasis symptoms include:
- Dry or scaly skin
- Raised skin
- Itching
- A psoriasis rash
- Psoriasis patches
- Nail changes
One of the main signs of psoriasis is a raised patch covered with scales. These are often called psoriasis plaques.
Psoriasis can look different on different skin tones. Some people may develop red patches on skin psoriasis, while others may notice darker or lighter areas.
Itchy skin psoriasis can cause discomfort. Dry skin psoriasis may also become irritated or cracked.
If you have a lasting rash or unusual skin changes, see a healthcare professional for an accurate diagnosis.
What Causes Skin Disease Psoriasis?
There is no single answer to what causes psoriasis. The condition involves the immune system and may also be linked to genetics and other factors.
An overactive immune system can affect normal skin-cell growth. This can lead to a buildup of skin cells on the skin.
Having a family history of psoriasis may also mean a higher risk of developing it.
Some factors can trigger a psoriasis flare. Triggers vary between people and may include stress, skin injuries, infections, and some medicines.
An infection such as strep throat may be linked with guttate psoriasis in some people.
