What is psoriasis?

Psoriasis is a chronic skin disease that is characterized by the growth of new skin cells too quickly. As a result, new skin cells will continue to accumulate on the surface to form red, thick, and scaly patches.

This condition includes autoimmune diseases whose exact cause is unknown. Apart from problems with the immune system, psoriasis usually appears to be triggered by a variety of factors both from within and from the environment.

This disease is a recurrence. That is, the symptoms of the disease can disappear or recur later. Apart from that, there is no cure for psoriasis. But do not worry because there are many drugs that can help control the symptoms.

How common is psoriasis?

Psoriasis is quite common and usually occurs in adults. Men and women are equally susceptible to psoriasis. However, you can minimize your chances of developing psoriasis by reducing the risk factors.

Even sometimes, bumps also appear on the face, scalp, and ears. The bump usually looks like:

  • Small and scaly
  • Pink

This condition most often strikes those in young adults and children. Usually this condition is triggered by bacterial infections such as strep throat.

Various symptoms can come and go for life or even only appear once in a lifetime.

Inverse psoriasis

This type usually appears and develops in areas of the skin that stick together such as the armpits, genitals, and buttocks folds. Generally this type of skin problem is triggered by a fungal infection in the skin.

Cause

What causes psoriasis?

There are two possibilities that can cause this skin disease, namely:

Disorders of the body's immune system

Experts do not yet know exactly what causes psoriasis. However, this condition is strongly suspected due to disorders of the immune system.

The immune system contains white blood cells called T lymphocytes to detect and fight foreign substances such as viruses or bacteria.

Unfortunately due to an error, T cells actually attack healthy cells as if they were fighting a wound or infection.

This attack causes the body to make new skin cells more often than it should. As a result, there are heaps of extra skin cells on the skin.

Therefore, psoriasis is a health problem which is also referred to as an autoimmune disease.

Genes

The scientists found that people with certain genes were more likely to develop psoriasis.

However, this does not apply to everyone. The reason is, there are people who have this disease without having these genes.

In addition, there are also people who have the psoriasis gene but have never been affected by health problems on this one.

Therefore, scientists believe that a person needs to be exposed to the trigger before the disease appears.

Risk factors

What increases my risk for psoriasis?

Here are various factors that increase a person's risk for skin disease this one, namely:

Family history

Psoriasis is a family inherited disease. Having a family or parents with psoriasis increases your risk of developing the same disease.

The more family members who have this disease the more likely you are to be affected.

Viral and bacterial infections

People with viral and bacterial infections in their bodies are more susceptible to psoriasis than those who are not. This condition is especially vulnerable in children and young adults who are often exposed to recurrent infections, especially strep throat.

Stress

Stress can weaken your immune system. Therefore, it is not surprising that excess stress is one of the factors that can increase the risk of psoriasis.

Obesity

People who are overweight are also at high risk for psoriasis. Because, obesity stimulates inflammatory triggering factors in the body. In addition, lesions in psoriasis are also easy to develop in the folds of the skin.

Smoke

Smoking not only increases the risk of this one skin disease. However, smoking can also increase disease severity due to nicotine and tobacco content which can trigger inflammation.

The various factors that have been mentioned are the most common. However, do not rule out the possibility you can get this disease without having one of the factors mentioned.

What are the triggers for psoriasis?

This autoimmune skin disease can appear at any time if you:

  • Having sores on the skin such as blisters or insect bites
  • Drinking too much alcohol
  • Drastic hormonal changes occur especially in women (for example during puberty and menopause)
  • Take certain medications such as lithium, antimalarial, anti-inflammatory, and beta blockers
  • Frequent infections such as strep throat
  • Experiencing extreme weather changes

Everyone has different triggers for psoriasis. Therefore, the sufferer must know what factors trigger the emergence of symptoms to avoid it.

Diagnosis & treatment

The information provided is not a substitute for medical advice. ALWAYS consult your doctor.

What are the usual tests for psoriasis?

Physical examination and biopsy are the two main procedures for diagnosing psoriasis.

Physical examination

The doctor will usually do a physical examination and medical history in advance to check this condition. The doctor will examine the skin, scalp, and nails to see possible diseases from the symptoms indicated.

In addition, the doctor will also ask for a family health history. The goal is to check whether you have a decreased risk of psoriasis from your family.

Skin biopsy

If needed, the doctor will usually take a small sample of the skin to be examined. Before taking a skin sample, the doctor will first give local anesthesia. Then, the sample will be examined under a microscope for further investigation.

What are my treatment options for psoriasis?

Psoriasis cannot be cured but treatment can help control the symptoms. Treatments are generally divided into three categories, namely topical, oral or injection drugs, and light therapy.

Topical medication

The following various topical medications that are usually prescribed are:

Corticosteroids

This medicine can reduce inflammation and itching. A mild dose of ointment is for sensitive areas such as the face or skin folds.

While strong doses are usually used to treat other areas that are smaller, less sensitive, and more difficult to treat.

Retinoids

This drug is a derivative of vitamin A to help reduce inflammation. You need to be careful when wearing it.

Because the side effects of this drug make the skin more sensitive when exposed to the sun and easily irritated. For that, you need to use sunscreen when outdoors activities.

Anthralin

This drug helps inhibit skin cell growth. In addition, anthralin can also remove scales, making the skin smoother.

However, this one topical medication can also irritate the skin. Therefore, be sure to read the instructions for use before applying it to the skin.

Salicylic acid

Salicylic acid helps shed dead skin cells and reduce crust. Usually this drug is available in the form of shampoo or ointment.

Vitamin D analogues

Vitamin D analog is an artificial vitamin D product that helps slow the growth of skin cells. Calcipotriene is a prescription cream that contains vitamin D analogues to treat mild to moderate psoriasis.

Calcineurin inhibitors

Calcineurin inhibitors aim to reduce inflammation and plaque buildup. Although effective, this drug is usually not recommended for long-term use. The reason can increase the risk of skin cancer and lymphoma.

Coal tar

Coal tar or coal tar helps reduce crust, itching, and inflammation of the skin. Usually this drug is available in the form of shampoo, cream and oil. However, coal tar cannot be used for women who are pregnant or breastfeeding.

Moisturizer

Moisturizer is not going to help cure this one skin disease. However, this care product keeps the skin moist.

That way, the skin will avoid dryness which can make it more itchy. To lock in skin moisture, use immediately after bathing while the skin is still half dry.

Drugs or injection

For people with moderate to severe disease, the doctor will give oral medication or injections. These medicines will directly enter the body and the bloodstream system.

As for various drugs that are usually prescribed namely:

  • Methotrexate
  • Cyclosporine (Sandimmune)
  • Drugs that change the immune system (biological)
  • Retinoids

Light therapy

Light therapy is an additional treatment procedure for psoriasis that is often recommended. This treatment procedure usually uses natural or artificial ultraviolet light.

Light therapy can help kill white blood cells that are too active in attacking healthy skin cells. The doctor will use ultraviolet A (UVA) and ultraviolet B (UVB) light to help reduce symptoms. The type and amount of therapy is adjusted to the severity and condition of your skin.

In addition, light therapy is also a complementary treatment for this health problem. The goal is to make the symptoms of this autoimmune disease no longer hinder your activities.

Home remedies

What are some lifestyle changes or home remedies to treat psoriasis?

Psoriasis is an incurable disease. However, a combination of doctor's medication and home care can help alleviate the condition. Here are various things you can do:

  • Bathing regularly to remove crust and moisturize the skin
  • Bask in the sun in the morning
  • Do not drink alcoholic beverages
  • Applying aloe to the skin to relieve inflammation
  • Take fish oil supplements to reduce inflammation from the inside
  • Limit eating foods that trigger inflammation such as red meat and dairy products

Do not hesitate to consult a doctor if the symptoms experienced are very disturbing. In addition, join a support group of people with psoriasis and professionals so you don't feel alone.

If you have questions, consult your doctor for the best solution for your problem.
