long lasting psoriasis

Overview

Long-lasting psoriasis, also called chronic psoriasis, is a skin condition that causes patches of thick, inflamed skin covered with silvery scales. It happens when the body makes new skin cells faster than it can shed old ones. These patches, known as plaques, can come and go over many years.

Yes. Psoriasis affects about 2 to 3 in every 100 people worldwide, which makes it one of the most common long-term skin conditions.

Psoriasis can begin at any age, but it most often starts between the ages of 15 and 35. It also affects children and older adults, and people of all skin tones.

Symptoms

Common symptoms

• Raised red patches of skin, sometimes with a silvery-white scale on top
• Dry, cracked skin that may bleed or itch
• Soreness or burning near the patches
• Thickened, pitted or ridged nails
• Scaling on the scalp

Symptoms in children

• Smaller, softer patches that may appear in the diaper area in babies
• Scaly scalp that may be mistaken for cradle cap
• Patches may be less red and more subtle on darker skin
• A strong family history of psoriasis is often present

Symptoms in older adults

• Skin may be thinner, making patches more fragile and prone to bleeding
• Patches may appear less typical, such as more widespread or less scaly
• Higher chance of joint symptoms
• Existing skin may be dry due to aging, which can make psoriasis feel worse

Causes

Main causes

• An overactive immune system that mistakenly attacks healthy skin cells, causing rapid skin cell turnover.
• Genes — psoriasis often runs in families, though not everyone with the genes develops it.
• Triggers that activate the condition, such as stress, skin injury, throat infection, certain medicines, or weather changes.

Risk factors

• Close family member with psoriasis
• Smoking or heavy alcohol use
• Being overweight or obese
• Repeated skin trauma, such as cuts, scratches, or sunburn
• A history of strep throat or other infections

When to see a doctor

See a doctor urgently if:

• If you have severe symptoms like widespread redness, pustules, or fever, call your local emergency number now.
• If you have sudden joint pain or swelling, seek same-day medical advice.
• If you have signs of a skin infection, such as oozing, warmth, or fever, see a doctor urgently.

Book a routine appointment if:

• If you notice a new patch of scaly skin that does not go away in a few weeks
• If your symptoms get in the way of daily life or your self-esteem
• If you have joint pain, stiffness, or swelling, especially in the morning
• If you need guidance on treatments and how to apply them safely

Diagnosis

Your doctor will usually diagnose psoriasis by examining your skin, scalp, and nails. They will ask about your symptoms, family history, and possible triggers. Sometimes they will take a small sample of skin, called a biopsy, if the diagnosis is unclear.

Tests that may be done

• Skin biopsy — taking a small piece of skin to be viewed under a microscope
• Blood tests — may be used to rule out other causes or check for inflammation
• Joint examination — if arthritis symptoms are present, you may be sent for further tests such as X-rays

What to expect at your appointment

The appointment is usually pain-free and takes around 15 to 20 minutes. Your doctor will look at the affected areas and may ask you about any other symptoms like joint stiffness. If you already have a diagnosis, they will work with you to manage flares and adjust your care.

Treatment

While there is no cure for psoriasis, many safe and effective treatments exist. The aim is to slow skin cell growth, reduce inflammation, and keep symptoms under control. Your doctor will tailor the plan to your skin type, age, and how much of your body is affected.

Self-care at home

• Moisturize your skin daily with a fragrance-free ointment or cream to lock in moisture and reduce flaking.
• Take short warm baths or showers and gently pat your skin dry — do not rub.
• Avoid known triggers such as stress, skin injuries, smoking, and heavy alcohol.
• Expose skin to small amounts of sunlight using a healthcare provider's advice, as too much sun can cause burns.
• Wear soft, loose clothing to reduce irritation.

Medical treatments

Treatments for psoriasis are grouped into topical (applied to the skin), light therapy (phototherapy), and systemic (pills or injections). Topical treatments include creams, ointments, and gels that reduce inflammation and scaling. Light therapy uses controlled ultraviolet light under medical supervision. For moderate to severe psoriasis, systemic medicines and advanced biologic therapies that target the immune system may be offered. Your doctor will explain the benefits and risks of each option and help you decide what is right for you.

When is surgery considered?

Surgery is not used to treat psoriasis itself. In rare cases, it may be considered for joint damage caused by psoriatic arthritis — talk to your specialist about whether this is an option for you.

Living with this condition

Living with psoriasis means building a simple daily routine: moisturize, take gentle care of your skin, and dress in comfortable fabrics. It helps to keep a small supply of moisturizer at work or in your bag so you can soothe itchy patches during the day. With the right routine, most people keep their skin calm and comfortable.

Lifestyle tips

• Manage stress through gentle exercise, deep breathing, or activities you enjoy.
• Moisturize daily, even on days when your skin looks clear.
• Protect skin from cuts, scratches, and sunburn.
• Avoid alcohol and stop smoking if you can — your healthcare team can help.
• Wear lighter layers that allow your skin to breathe.
• Keep nails short and smooth to avoid scratching and harming your skin.

Diet and exercise

There is no special diet that cures psoriasis, but eating a balanced, anti-inflammatory diet rich in fruits, vegetables, whole grains, and omega-3 fatty acids (such as oily fish) may help some people. Regular exercise helps keep your weight healthy and reduces stress. If you have limited joint mobility, choose low-impact activities like swimming or cycling, and always ask your doctor before starting a new exercise plan.

Mental health and emotional wellbeing

Psoriasis can affect how you feel about yourself and may lead to anxiety or depression. It is normal to feel frustrated, embarrassed, or low at times. If these feelings last longer than a few weeks or affect your daily life, talk to a mental health professional. Your doctor can also connect you with support services.

Prevention

You cannot prevent psoriasis from developing, but you can reduce the number of flares you have by avoiding your personal triggers and keeping your skin well cared for.

Vaccines

There is no vaccine to prevent psoriasis. However, staying up to date with routine vaccines is important because infections like strep throat can trigger or worsen flares.

Screening programmes

There is no routine screening test for psoriasis. If you have a family history, you may want to watch for early signs such as scaly patches or nail changes and report them to a doctor.

Complications

If left untreated

• Severe skin flares that cover large areas, which can cause extreme discomfort and fluid loss (erythrodermic psoriasis).
• Infections from scratching or cracks in the skin.
• Psoriatic arthritis, which causes stiff, swollen, and painful joints and can lead to joint damage over time.
• Higher risk of depression, anxiety, and low self-esteem.
• Possible links to heart disease, high blood pressure, and diabetes — talk to your doctor about regular checks.

Long-term outlook

Psoriasis is a long-term condition, but the outlook is usually very good. With modern treatment and a good self-care routine, most people achieve long periods of clear skin and lead full, active lives. Flares may still happen, but you will learn to manage them, and your healthcare team will be with you every step of the way.
