A Look At Psoriasis

Overview

Psoriasis is a long-lasting skin condition in which the immune system is overactive and makes new skin cells too quickly. These cells build up on the surface and form thick, scaly patches that may itch or hurt. It is not contagious, and it is not caused by poor hygiene.

Yes, psoriasis is common. About 2 to 3 out of every 100 people around the world have it.

Psoriasis can start at any age, but it most often appears in adults under 35. It affects men and women equally and often runs in families.

Symptoms

Common symptoms

• Thick, raised patches of red, purple, or grey skin, often covered with silvery or whitish scales.
• Dry, cracked skin that may itch, burn, or sting.
• Nails that are thick, ridged, or pitted, or that separate from the nail bed.
• Stiff, swollen, or painful joints, which may be a sign of psoriatic arthritis.

Symptoms in children

• Patches may be smaller, softer, and less scaly than in adults.
• A red rash in the diaper area that does not clear with regular diaper cream.
• Scaly patches on the scalp that are sometimes mistaken for cradle cap or dandruff.

Symptoms in older adults

• Skin is often thinner and more fragile, so patches may bruise easily.
• Patches may be less red but still very itchy.
• Skin folds, such as under the arms or in the groin, may be affected more often.

Causes

Main causes

• An overactive immune system that mistakenly attacks healthy skin cells.
• Genetic factors that make some people more likely to develop psoriasis.
• Not caused by poor hygiene, stress alone, or infection. Stress and infections can trigger flares but are not the root cause.

Risk factors

• Family history of psoriasis.
• Infections such as strep throat or skin infections.
• Stress.
• Smoking or exposure to tobacco smoke.
• Heavy alcohol drinking.
• Obesity.

When to see a doctor

See a doctor urgently if:

• Seek same-day medical care if you have sudden joint swelling, signs of skin infection, or a severe, painful flare that spreads quickly.

Book a routine appointment if:

• Make a routine appointment if you have patches, scaling, nail changes, or itching that lasts longer than a week.
• See a doctor if over-the-counter moisturizers and gentle skin care do not improve your symptoms.

Diagnosis

A healthcare provider will usually diagnose psoriasis by looking at your skin, scalp, and nails. They will also ask about your health history, any symptoms like joint pain, and whether anyone in your family has psoriasis.

Tests that may be done

• Skin biopsy: a tiny sample of skin is removed and looked at under a microscope.
• Joint assessment and possibly imaging tests if you have joint pain or swelling.
• Blood tests are sometimes used to rule out other conditions, but they are not needed for most cases.

What to expect at your appointment

The provider may refer you to a skin specialist called a dermatologist. The diagnosis is usually based on how the rash looks and its pattern. Most of the time, no urgent tests are needed.

Treatment

Psoriasis has no cure, but it can be well controlled. Many people achieve clear or nearly clear skin with the right treatment. The best plan depends on how much skin is affected, where it is, and your overall health.

Self-care at home

• Moisturize your skin every day with a thick, fragrance-free cream or ointment.
• Take short, lukewarm baths and pat your skin dry gently.
• Avoid scratching and use a soft towel.
• Manage stress with relaxation exercises, meditation, or talking to friends.
• Protect your skin from sunburn. A little gentle sunlight can help some people, but follow your doctor's advice.

Medical treatments

Your doctor may recommend treatments applied to the skin, light therapy, or medicines that work on the immune system. Pills and injections are usually reserved for moderate to severe cases. Your healthcare provider will discuss the options and help you choose safely.

When is surgery considered?

Surgery is not a standard treatment for psoriasis. If psoriatic arthritis is severe, a specialist might consider joint procedures, but this is uncommon.

Living with this condition

Psoriasis tends to come and go. You may have times when it is quiet and times when it flares. Learning your personal triggers and having a gentle daily skin routine can make a big difference.

Lifestyle tips

• Keep a diary of flare-ups to help identify your triggers.
• Wear loose, soft, comfortable clothing to avoid rubbing.
• Use a humidifier in dry rooms to keep your skin from drying out.
• Keep your nails trimmed and smooth if you have nail psoriasis.
• Join a support group, in person or online, to share experiences with others.

Diet and exercise

A balanced diet and regular physical activity can help you maintain a healthy weight, which may reduce the severity of psoriasis. There is no special psoriasis diet that works for everyone, but eating plenty of vegetables, whole grains, and lean proteins and limiting alcohol is a good choice.

Mental health and emotional wellbeing

Psoriasis can affect your confidence and mood. Many people feel embarrassed, anxious, or frustrated, and depression is more common in people with psoriasis. Your feelings matter. Talk to your healthcare team about counseling or support. If you ever have thoughts of harming yourself, call your local emergency number right away or ask someone to help you.

Prevention

Psoriasis cannot be prevented because it is partly genetic. However, you may be able to prevent or reduce flare-ups by avoiding your known triggers, keeping your skin well moisturized, and staying healthy.

Vaccines

Keep your routine vaccinations up to date. If you take a treatment that affects your immune system, talk to your doctor before receiving any live vaccine.

Screening programmes

There is no specific screening test for psoriasis. But regular health check-ups can help monitor for related conditions such as high blood pressure, diabetes, and joint problems.

Complications

If left untreated

• Psoriatic arthritis, causing pain, stiffness, and swelling in the joints.
• Higher risk of heart disease and stroke.
• Type 2 diabetes and high blood pressure.
• Eye inflammation, such as conjunctivitis (pink eye).
• Anxiety, depression, and reduced quality of life.

Long-term outlook

Psoriasis is a long-term condition, but the outlook is generally good. With today's treatments, most people can control their symptoms and live a full, active life. It may take time to find the right plan, but your healthcare team will help you. Stay hopeful and keep the lines of communication open.
