Many people may find themselves scratching and itching in different parts of their bodies. But how do you know if it’s psoriasis? What are the psoriasis causes you should know about? And are you at risk?
Psoriasis is a common skin disease that causes red itchy patches on the knees, elbows, trunk, and scalp, among other places. It is a long-term chronic condition that tends to recur and flare up repeatedly, causing discomfort.
The inflammation that psoriasis causes can affect various organs and tissues in the body. Other health problems can arise for those who have psoriasis.
Psoriasis skin rashes can take place in any part of the body. But, for the most part, it affects the following:
Psoriasis causes a person to feel itchy and uncomfortable, and it can affect mental health as well. Many who suffer from psoriasis feel self-conscious about themselves.
When an overactive immune system enhances the growth of skin cells, psoriasis takes place. A month is enough time for normal skin cells to grow and shed (fall off). However, with psoriasis, skin cells do this in just three to four days. Instead of shedding, skin cells accumulate on the skin’s surface.
Many people who are prone to psoriasis may go on for years without experiencing symptoms at all. This disease can be triggered by an external factor such as one or more of the following:
Other known risk factors are associated with a person’s family history. Having a family member with this condition increases the risk for the children to also develop psoriasis.
It is not true that psoriasis causes another person to develop the condition when the two come in contact. People should not be afraid of psoriasis because it is a non-contagious skin condition. Other people who do not have it must not discriminate as well.
Signs and symptoms may be different for every psoriasis case. The most common ones are:
As psoriasis can occur in many different sizes, shapes, and forms, other types distinguish one from another.
This is the most common type of psoriasis that can be identified through the dryness and redness of the skin patches. These patches are normally covered with silvery scales on top of the area that look like dandruff. A person with this type of psoriasis may feel itching and pain on the knees, elbows, or scalp.
Even small parts of the skin can get psoriasis. This kind of psoriasis causes abnormal nail growth and discoloration. The nails of people with psoriasis may weaken and detach from the nail bed. In severe circumstances, the nail may also crumble.
This type is common for children and young adults who have a bacterial infection (like strep throat). Small, drop-shaped scaling lesions appear on the trunk, limbs, and legs.
Fungal infections cause this type of psoriasis to develop in certain areas like the buttocks and breasts. Smooth areas of red skin develop in inverse psoriasis, which increases with friction and sweating.
An uncommon type of psoriasis involves pus-filled sores on the palms of the hands or the soles of the feet. These appear either in large patches (generalized pustular psoriasis) or smaller areas.
Erythrodermic psoriasis is an uncommon kind of psoriasis that can cover the entire body with red peeling rashes. It makes the person feel intense sensation of itching and burning.
This kind of psoriasis is characterized by swollen, painful joints, which are common symptoms of arthritis. Psoriatic arthritis can affect any joint and has a wide range of symptoms. It can produce stiffness and increasing joint deterioration, which can lead to permanent joint damage in severe cases.
