Every day with Psoriasis raises a new question

What Is Psoriasis?

Psoriasis is a long-term immune-mediated condition that causes skin cells to build up more quickly than usual. This creates inflamed, raised or scaly areas of skin that may itch, burn or feel painful. Symptoms often alternate between flares and periods when the skin improves or clears. Psoriasis is not contagious.

‍

What Causes Psoriasis?

Psoriasis develops when the immune system becomes overactive and speeds up the production of skin cells. The exact reason this happens is not fully understood, but genetics and environmental factors both appear to play a role. Psoriasis is not caused by poor hygiene or something a person has done.

‍

Emotional Well-Being

Visible skin changes, itching and unpredictable flares can affect confidence and emotional well-being. Some people experience embarrassment, isolation, anxiety or low mood.

These experiences are an important part of psoriasis care and should be discussed with the healthcare team. Seeking emotional support does not mean that psoriasis is “all in the mind.”

‍

Types of Psoriasis

Plaque psoriasis is the most common type and causes raised, scaly patches. Guttate psoriasis causes small spots and may appear after an infection. Inverse psoriasis develops in skin folds and often looks smooth rather than scaly.

Pustular psoriasis causes pus-filled bumps, while erythrodermic psoriasis causes widespread redness and shedding of the skin. A person may experience more than one type during their lifetime.

‍

How Is Psoriasis Treated?

Treatment depends on the type of psoriasis, the areas affected, its severity and how much it affects daily life. Options may include creams or ointments, phototherapy, tablets, injections and biologic treatments.

There is no single treatment that works for everyone. Some people need to try different treatments or combinations before finding an approach that controls their symptoms effectively.

Skin Care and Daily Life

Moisturizing regularly can help reduce dryness, scaling and discomfort. Avoiding scratching and treating cuts or skin irritation carefully may also help prevent symptoms from worsening.

Psoriasis can affect sleep, clothing choices, work, relationships and social activities. A treatment plan should consider not only the amount of skin affected but also how the condition influences everyday life.

‍

Who is at risk of developing psoriasis?

Anyone can develop psoriasis. Having a family history of the condition may increase the likelihood because certain genes influence how the immune system works.

Smoking, obesity, certain infections and some medicines are also associated with a higher likelihood of developing psoriasis. However, having a risk factor does not mean that someone will definitely develop the condition.

Psoriasis affects more than the skin. People with psoriasis have a higher likelihood of developing certain other conditions, including cardiovascular disease, metabolic syndrome, diabetes, inflammatory bowel disease, anxiety and depression.

This does not mean that everyone with psoriasis will develop these conditions. Regular health checks can help identify and manage additional risks.

‍

What are the symptoms of psoriasis?

Common symptoms include raised or thickened areas of skin, scaling, itching, burning, soreness and dry skin that may crack or bleed. Psoriasis commonly affects the scalp, elbows, knees, lower back, palms and soles, but it can appear anywhere.

It can also affect the nails, causing small dents, discoloration, thickening or separation from the nail bed. The appearance of psoriasis may vary across different skin tones.

Some people with psoriasis develop psoriatic arthritis, which causes inflammation in the joints and the areas where tendons connect to bones. Symptoms may include joint pain, swelling, stiffness, back pain or pain around the heel.

New or persistent joint symptoms should be discussed with a healthcare professional promptly because untreated psoriatic arthritis can cause permanent joint damage.

‍

How is psoriasis diagnosed?

A healthcare professional usually diagnoses psoriasis by examining the skin, scalp and nails and asking about symptoms, joint problems and family history. A small skin sample may occasionally be taken to rule out other conditions.

There is no single blood test that confirms psoriasis, although tests may sometimes be used to investigate joint symptoms or other possible conditions.
