psoriasis complications awareness

Overview

Psoriasis is a long-lasting skin condition that causes patches of thick, red skin covered with silvery scales. It happens when the body's immune system gets misdirected and makes new skin cells too fast. These patches can itch, crack, or feel sore.

Yes. Psoriasis affects millions of people worldwide — roughly 2 in 100 people.

Psoriasis can begin at any age, but it most often first appears between 15 and 35 years old. It affects men and women equally. You are more likely to get it if a close family member has it.

Symptoms

Common symptoms

• Patches of red, thickened skin with silvery-white scales
• Dry, cracked skin that may bleed or sting
• Itching, burning, or soreness around the patches
• Thickened, pitted, or ridged nails
• Joint swelling, stiffness, or pain (this can be a sign of psoriatic arthritis)

Symptoms in children

• Young children often get smaller, thinner plaques
• The scalp and diaper area are common spots
• Itching can be intense and may disturb sleep or concentration

Symptoms in older adults

• Skin may be thinner and the scales less obvious, but the rash can be more widespread
• More likely to report joint pain or stiffness
• Aging skin and medications for other conditions can make dryness and irritation worse

Causes

Main causes

• Psoriasis is an immune-mediated condition — the immune system mistakenly attacks healthy skin cells, speeding up their production
• Genes play a major role; psoriasis often runs in families
• Triggers such as skin injuries, stress, throat infections, cold weather, smoking, or heavy alcohol use can start or worsen a flare

Risk factors

• Having a parent, sibling, or other close relative with psoriasis
• Repeated skin trauma from cuts, scrapes, sunburn, or friction
• Recent bacterial infections, especially strep throat
• Smoking, heavy alcohol use, and certain medicines
• Obesity and insulin resistance

When to see a doctor

See a doctor urgently if:

• A rash that is spreading quickly, covers a large area, or is very painful
• Swollen, stiff, or painful joints that last more than a few days
• Any sign of skin infection

Book a routine appointment if:

• A skin patch that lasts longer than two weeks or does not improve with moisturizers
• Symptoms that interfere with sleep, work, or social life
• Nail changes that you cannot explain
• Questions about treatment options or a new management plan

Diagnosis

A doctor or dermatologist usually diagnoses psoriasis by looking at your skin, scalp, and nails and asking about your personal and family history of skin conditions and joint symptoms.

Tests that may be done

• Skin biopsy: a tiny sample of skin is removed and examined under a microscope to confirm the diagnosis
• Blood tests: sometimes used to rule out other conditions or to check for markers of inflammation
• Joint examination and possibly X-rays or ultrasound if you have joint pain or stiffness

What to expect at your appointment

The examination is usually quick and painless. If a biopsy is needed, a local numbing medicine is used. After the assessment, your healthcare team will explain whether you have psoriasis and outline a treatment plan that fits your situation.

Treatment

Psoriasis is a lifelong condition, but treatment can control symptoms, clear the skin, and reduce the risk of arthritis and other complications. Most treatment is tailored to how severe the condition is and how it affects your life.

Self-care at home

• Moisturise your skin every day with thick creams or ointments
• Use gentle, fragrance-free cleansers and lukewarm water
• Protect your skin from cuts, scrapes, and sunburn
• Manage stress with relaxation, breathing exercises, or counselling
• Avoid smoking and limit alcohol — both can make flares worse

Medical treatments

Medical treatments fall into three general groups: creams and ointments applied to the skin (called topicals), light therapy using controlled ultraviolet light, and medicines that work throughout the body (called systemic treatments). Your doctor will recommend options based on your skin type, how severe your psoriasis is, and your medical history. Always follow the plan they give you, and never stop treatment without asking first.

When is surgery considered?

Surgery is not a standard treatment for psoriasis itself. However, if psoriasis has damaged your nails or joints severely, a specialist may discuss procedures to relieve symptoms. Ask your healthcare team about what might help in your case.

Living with this condition

Having a simple, soothing skincare routine can make a big difference. Set aside a few minutes each morning and night to moisturize and check your skin. Wear soft cotton clothing, avoid harsh fabrics, and use a humidifier indoors during dry weather.

Lifestyle tips

• Take warm (not hot) baths with bath oil or oatmeal-based products
• Get gentle, short periods of sunlight every day — never allow the skin to burn
• Keep nails trimmed to reduce scratching and prevent nail damage
• Find a stress-reducing activity you enjoy, such as walking, meditation, or a hobby
• Wear loose clothing to avoid rubbing irritated areas

Diet and exercise

There is no single 'psoriasis diet,' but an anti-inflammatory eating pattern rich in fruits, vegetables, whole grains, lean protein, and healthy fats supports overall health and may reduce flares. Regular exercise helps manage weight, reduces stress, and can lower the risk of heart disease and arthritis.

Mental health and emotional wellbeing

Living with a visible skin condition can take a toll on self-esteem. Many people with psoriasis feel embarrassed, anxious, or low. These feelings are common and are not a sign of weakness. Talk to your healthcare team if psoriasis affects how you feel about yourself or your daily life — they can offer support and, when needed, recommend mental health services.

Prevention

You cannot prevent psoriasis itself, but you may be able to reduce flare-ups by looking after your skin, managing stress, avoiding known triggers, and treating infections promptly. Early and consistent treatment can also reduce the risk of complications like psoriatic arthritis.

Vaccines

Routine vaccinations are generally recommended for people with psoriasis. Some psoriasis treatments can increase the risk of infection, so talk to your healthcare team about staying up to date with vaccines — including flu and COVID-19 — before you start or change treatment.

Screening programmes

Because psoriasis is linked with higher rates of high blood pressure, diabetes, and heart disease, your doctor may suggest regular checks for these conditions even if you feel well. Ask at your annual check-up about blood pressure, blood sugar, and cholesterol.

Complications

If left untreated

• Psoriatic arthritis — a form of joint inflammation that causes pain, swelling, and stiffness and can lead to permanent joint damage
• Cardiovascular disease — a higher risk of high blood pressure, heart attack, and stroke
• Metabolic syndrome — a cluster of conditions including high blood sugar, abnormal cholesterol, and excess abdominal fat
• Eye problems — a small number of people develop inflammation in the eyes (uveitis)
• Mental health conditions — including anxiety and depression related to living with a visible condition
• Skin infections — from scratching cracked or broken skin

Long-term outlook

The outlook for psoriasis is better than ever. Most people can control their symptoms with a combination of treatments and lifestyle habits, and they live full, active lives. The earlier you seek help, the better your chance of avoiding complications. Even if psoriasis is severe, modern care offers many effective options and there is always hope.
