Psoriasis is a skin disease affecting over 125 million people worldwide. It causes red, dry and scaly patches on the skin that can be itchy or sore. These patches often appear on areas like the elbows, scalp, knees and lower back, but they can show up anywhere. Importantly, psoriasis is not contagious, which means you can't catch it from someone else.
In this blog, we’ll explain what psoriasis is, how it’s different from eczema and what causes it.
What is psoriasis?
Psoriasis is a chronic skin problem that is characterised by red, dry and scaly skin areas. These patches can be sore or itchy and are often seen on the elbows, knees, scalp and lower back, but they can show up anywhere on the body. Psoriasis happens because the immune system makes skin cells grow too quickly. Instead of taking weeks, the skin cells build up in just a few days, leading to thick patches.
Psoriasis is not contagious, which means you can't catch it from someone else. It can come and go, with times when it gets worse (called flare-ups) and times when it gets better. There’s no cure, but treatments like creams, light therapy or tablets can help manage the condition.
Difference between eczema and psoriasis
Eczema and psoriasis are both skin conditions, but they are not the same. Here are the key differences:

|
Red, dry, cracked skin (can ooze)
|
Red patches with thick, silvery scales
|
Itching

What causes psoriasis?
The exact cause of psoriasis is unknown, but studies show it is related to an overactive immune system, in which a person’s immune system gets attacked by healthy skin cells by mistake, causing inflammation and impacting other organs and tissues in the body. Moreover, scientists do not fully understand what triggers the faulty immune cell activation against its cells, but they know that its activation involves a combination of genetics and environmental factors.
Some external factors that may increase the risk of developing psoriasis in a person include:
- Problems with the immune system
One of the main types of cells of the immune system is called a T-cell which usually travels through the body to detect and fight invading germs, such as bacteria. But in the condition of psoriasis, the immune cells start to attack healthy skin cells causing the deepest skin layer to produce new skin cells within 3-4 days, which usually takes a month. This triggers the immune system to produce more T-cells. However, the exact reason for this problem is not known but certain factors like genes and environmental factors may play a role.
People living with psoriasis are also known to have a family history of this condition, and researchers have pinpointed some genes that may contribute to its development. Different combinations of these genes may likely make people more prone to developing the condition.
However, having these genes does not necessarily mean a person will develop psoriasis and most of them play an important role in the function of the immune system which during the condition of psoriasis activates the immune response.
- Other reasons for psoriasis
In case of early psoriasis, the symptoms may go unnoticed but later get triggered with involvements of certain factors like:
- An injury to the skin like a cut, scrape, insect bite or sunburn; often known as the Koebner response.
- Drinking excessive amounts of alcohol
- Smoking
- Stress
- Hormonal changes in women during puberty and menopause
- Certain medicines like anti-malarial, and anti-inflammatory including ibuprofen, and ACE inhibitors
- Throat infections usually occur in children and young adults and sometimes trigger a form of psoriasis called guttate psoriasis which develops after a streptococcal bacteria infects the throat that may later develops into psoriasis.
- Some other immune disorders, such as HIV, heart-related disease, malaria or mental health problems
Conclusion
Living with psoriasis can be very challenging, but understanding the condition can help manage it better. Although there is no cure, treatments like creams, light therapy or tablets can make a big difference. It’s also important to know your triggers and see a doctor for the right diagnosis and treatment.
If someone in your family has psoriasis, having medical insurance like a family health insurance can be very helpful. With the right plan, you could get faster access to specialists, dermatologists and private treatments, which can make managing psoriasis easier and less stressful.
