Understand Psoriasis: Causes, Symptoms, and Treatments

Discover the causes, symptoms, and treatments for psoriasis, a chronic autoimmune skin condition characterized by red, scaly patches.

Psoriasis is a long-lasting autoimmune disease. It makes the immune system react too much. This causes the skin cells to grow quickly.1 As a result, thick, red, scaly patches of skin form. They usually show up on the scalp, elbows, knees, and lower back.1 Psoriasis doesn’t spread between people. However, it might be in your family. Both genes and things in the environment can lead to psoriasis.1 The signs of psoriasis differ a lot. You could see small, red, scaly areas or large, swollen patches. Psoriasis can also flare up and then get better again.1 There are many ways to treat psoriasis. This includes using creams, light therapy, and medicines. Also, keeping stress low, eating well, and taking care of your skin can make a big difference.

Key Takeaways

  • Psoriasis is a chronic autoimmune skin condition that causes the rapid production of skin cells, leading to red, scaly patches.
  • Psoriasis can affect people of all ages, but it is more common in adults, and genetics play a significant role in its development.
  • There are several different types of psoriasis, each with its own distinct appearance and symptoms.
  • Psoriasis is associated with an increased risk of developing other health problems, including psoriatic arthritis and cardiovascular disease.
  • While there is no cure for psoriasis, a variety of effective treatment options are available, including topical creams, phototherapy, and systemic medications.

Overview of Psoriasis

Psoriasis is a disease where your immune system goes too strong, making too many skin cells. This creates patches of red, scaly skin.1

What is Psoriasis?

It’s a long-lasting issue with your immune system. It makes your skin cells grow too fast, leading to thick, red, scaly patches. These patches can pop up all over but are often found on the scalp, elbows, knees, and lower back.2

Who Gets Psoriasis?

It can hit anyone, but adults more than kids. A 1985 report in the Journal of the American Academy of Dermatology found late-onset psoriasis in 65% of cases, and early-onset in 35%.3

Risk Factors for Psoriasis

Having family history matters. Genetics are a big piece of the puzzle. If a parent has psoriasis, your risk grows. If both parents have it, the risk increases even more.1

Things like infections, certain drugs, stress, or skin injuries can also kickstart psoriasis.1

Types of Psoriasis

Psoriasis comes in different forms, each unique. Knowing the types is key to diagnosis and treatment.4

Plaque Psoriasis

This type is very common, seen in about 80% of cases.5 It shows up as red, scaly patches, often on elbows, knees, and the scalp.4

Guttate Psoriasis

Guttate psoriasis affects mostly children and young adults, making up about 8% of cases.5 It’s linked to throat infections and can turn into plaque psoriasis in some cases.45

Pustular Psoriasis

Affects mostly adults, showing as pus-filled bumps.5 It can be triggered by various things like stress or medication.4

Inverse Psoriasis

This type is found in skin folds and can get worse with friction and sweat.4

Erythrodermic Psoriasis

Very rare but serious, covers much of the body with fiery, burn-like skin.5 It can be triggered by severe sunburn or some meds.4

It’s vital for doctors to quickly spot the signs of each psoriasis type. This knowledge helps in providing the right care for those affected.

Symptoms of Psoriasis

Psoriasis shows up differently for everyone, but red, scaly skin patches are common. Often, these patches appear on the scalp, elbows, knees, or lower back. They might be itchy, hurt, and not look good.4 Changes in nails, like pitting and discoloration, are signs too.4 If your scalp has white scales, it could be scalp psoriasis.4

Psoriatic Arthritis

Some with psoriasis also get psoriatic arthritis, which affects the joints.4 It can cause pain, stiffness, and make moving hard.4 About 30% of those with psoriasis have it.6 Early treatment is key to managing it.6

Psoriasis symptoms can be mild or severe, depending on the person.6 For some, it’s just occasional discomfort. For others, it’s a daily struggle.6 Knowing the possible symptoms and getting the right care is important. It helps manage this long-term condition.

Psoriasis Symptoms

Causes of Psoriasis

The exact reason for psoriasis is not fully known. It seems to happen because of both genes and things in our surroundings.1 Scientists have found over 80 genes that might play a part in getting psoriasis. This shows genes are really important.1

Immune System Dysregulation

Psoriasis is a problem with the immune system, making it work too hard.4 The body makes new skin cells too quickly. This causes the itchy, red patches we see on the skin.

Genetic Factors

If someone in your family has psoriasis, you might get it too.1 If your mom or dad has it, your chance is higher. If both do, it increases even more.1

Environmental Triggers

Besides genes, things like infections or stress can start or make psoriasis worse.1 Other triggers are some medicines, skin injuries, cold dry weather, and smoking.1


Psoriasis is a long-lasting skin condition that affects many across the globe.7 It causes a fast growth of skin cells, resulting in red, scaly patches that itch and can be painful.1 It often starts in childhood and can run in families.1

People with psoriasis might also face other health problems. These include a type of arthritis, heart disease, being overweight, and issues with mental health.1 Things like infections, skin injuries, smoking, and certain meds can make it worse.1

While psoriasis can’t be cured, there are many ways to help manage it.7 Most cases are not severe, and options like creams, light therapy, and pills can help keep it under control.7 Managing stress, eating well, and avoiding what makes it worse are also important.

It’s key for anyone with psoriasis to understand their condition and treatment options. Working closely with doctors and looking at the whole picture can make a big difference. Many find they can improve their life by taking a comprehensive approach.


Diagnosis of Psoriasis

Doctors usually diagnose psoriasis with a physical exam.8 They look at the skin for red, scaly patches. Sometimes, they’ll also ask about your health history and if others in your family have had psoriasis.

Physical Examination

Psoriasis is diagnosed by looking at the skin, scalp, and nails for signs. They may ask about itching or burning, recent illnesses, and stress. They might also talk about the medicine you’ve taken, your family’s health history, and check your joint health.8

Laboratory Tests

If the signs aren’t clear, healthcare providers might order laboratory tests. These tests help rule out other skin problems. Tests could include a skin biopsy or blood tests to look for psoriasis markers.

Adding lab tests to the physical exam helps to confirm psoriasis. It also guides the doctors in creating the best treatment.89

Treatment Options for Psoriasis

People with psoriasis can choose from many treatments to keep their symptoms under control.9 The right treatment depends on how bad the psoriasis is and what type you have. Often, doctors rely on a mix of creams, light therapy, and medicines.

Topical Treatments

Topical treatments, like corticosteroids, work best for mild to moderate psoriasis.9 These lotions and creams can soothe the skin, easing swelling and redness. Shampoos and solutions with salicylic acid can cut down on flakes, crucial for scalp psoriasis. You can buy some over-the-counter, but stronger ones need a prescription.9


During phototherapy, the skin gets careful doses of UV light.9 Narrowband UVB is stronger but might cause worse side effects.9 It’s a solid choice if other treatments haven’t worked well for you.

Systemic Medications

For more severe psoriasis, systemic drugs might be needed. Biologics like etanercept or adalimumab, and drugs such as ustekinumab or methotrexate are common.9 These are usually taken by mouth or as injections to help slow down the skin cell’s overproduction. Cyclosporine is another option, but because it affects the immune system, it can’t be used for too long.9

In some cases, treatments that aren’t part of typical medicine can also improve symptoms, studies show.9

Lifestyle Management for Psoriasis

Alongside medical care, lifestyle plays a big part in handling psoriasis. Those with it can improve by managing stress, a good diet, and avoiding triggers. This is key to feeling better.

Stress Management

Chronic stress makes psoriasis symptoms worse and can lead to depression. Stress management practices, like mindfulness, meditation, plus hobbies, can help. This also reduces the risk of loneliness and feeling stigmatized.10

Diet and Nutrition

Eating well is vital for those with psoriasis. It boosts health and cuts down disease risks. Managing weight is crucial, as it lessens psoriasis flares and can lower medication needs.111012

A low-calorie diet has shown to better psoriasis and life quality. A plant-based diet can aid in this and help manage symptoms.1210

Avoiding Triggers

Finding and dodging triggers is good for handling psoriasis. This means avoiding too much alcohol. It makes treatments work better and manages symptoms longer.1011 Mixing alcohol with some drugs, like methotrexate, is harmful to the liver.10

Stopping smoking is crucial for those with psoriasis. Quitting can reduce risks of heart, liver, and gum diseases. It’s also key in avoiding other conditions like addiction, Crohn’s disease, and heart issues.11

A good lifestyle management plan can really help those with psoriasis. It improves symptoms, overall health, and cuts related disease risks.111012

Complications of Psoriasis

Psoriasis is more than a skin issue. It raises the chance of getting other health problems. These include1 psoriatic arthritis, heart issues, and mental health troubles.

Psoriatic Arthritis

About 30% of people with psoriasis get psoriatic arthritis (PsA). It makes joints stiff, swollen, and hurt13. Having psoriasis ups the PsA risk. They often happen together.

Cardiovascular Disease

People with psoriasis face more heart issues, high blood pressure, and stroke risks.1 The link is likely due to psoriasis’ chronic inflammation. It can cause heart problems like atherosclerosis.

Mental Health Issues

Psoriasis affects mental health too. It can bring on depression, anxiety, and more.1 The visible skin issues and unpredicable disease lead to low self-esteem, being alone, and lower life enjoyment.

Knowing these Psoriasis risks is crucial. Working closely with healthcare professionals can lower these risks. This helps manage the condition better.

Living with Psoriasis

Having psoriasis means facing challenges every day. This includes how your body looks and feels, and how you cope mentally. Still, with the right strategies and support, managing psoriasis gets easier, improving life quality.14

Coping Strategies

For those with psoriasis, beating stress is vital. This can be done through meditation, yoga, or just taking deep breaths.14 Living healthy by not smoking, drinking less, staying fit, and eating right also cuts the risk of other illnesses. This includes diabetes and heart problems.14

To keep psoriasis in check, it’s important to watch your skin closely, even when it looks fine. This habit helps avoid sudden flare-ups.14 Also, protecting your skin from harm is crucial. Use sunscreen and be gentle when you wash.15

Support Groups

Joining a psoriasis support group is a smart move. It offers a place where sharing, learning coping methods, and finding emotional backing happens.14 Being part of such a group tackles loneliness and its mental effects. These include feeling bad about yourself, stress, and possible depression.14

Support groups don’t just cheer you up; they can provide advice too. This might involve what treatments work best or how to talk to doctors.14 Talking to those in the same boat helps you take better care of yourself. It also boosts your management skills against psoriasis.
