Psoriasis is a skin condition that causes the formation of scales and red patches on the skin.
The word psoriasis is derived from Greek words psora and iasis which can be translated as “itch” and “condition” respectively and can be termed as “itching condition” or “being itchy.”The scales and patches formed due to psoriasis are itchy and painful.
Scales usually are noticed on the joints. However, they spread to other parts of the body, including:
Less common forms of psoriasis affect the mouth, nails, and the region surrounding the genitals.
Psoriasis is a chronic disease that often shows up and fades away in a repetitive manner. This condition is caused due to rapid cell build up on the surface of the skin. The severity of psoriasis could range from small patches to full body coverage.
According to a study carried out by the World Psoriasis Day Consortium, 125 million people all over the world (2-3 percent of the world’s population) are affected by psoriasis. Other studies state that 10-30 percent of people affected by psoriasis develop psoriatic arthritis, and is also linked with other health conditions, such as:
A combination of genetic and environmental factors is known to cause psoriasis. It could occur at any age but is known to commonly appear for the first time between 15 to 25 years of age. The numbers of cases reported are higher in regions that are far from the equator. While the condition is relatively uncommon in African Americans, it is seen to be very common in people with European ancestry. Individuals with irritable bowel syndrom, eulcerative colitis and Crohn’s disease are more vulnerable to psoriasis.
Most patients with psoriasis suffer mild symptoms like mild-skin lesions that can be treated easily and effectively with the use of topical therapies. For cases that range from moderate to severe, the patient may be subject to phototherapy, diet restrictions and other treatment procedures.
A number of theories exist on the causes of psoriasis through the precise causes are not fully understood. Factors like the following are believed to play a role in causing psoriasis:
Psoriasis is characterized by an abnormal growth of the outer layer of the skin. An overabundance of skin cells and abnormal production of cells during wound repair usually results in psoriasis. The usual time taken for skin-cell replacement is 28 – 30 days. But in the case of psoriasis, skin gets replaced every 3 to 5 days. Premature maturation of keratinocytes is believed to be a reason for this rapid growth.
Psoriasis is an autoimmune condition. In normal conditions, white blood cells are responsible for destroying foreign bacteria and fighting infections. In case of psoriasis, white blood cells are believed to attack skin cells mistakenly. This mistaken attack causes an overdrive in skin cell production, resulting in plaques that are associated with psoriasis.
Apart from other causes, there are a number of factors that trigger psoriasis. Some of the common trigger factors include skin injuries, stress, tension, cold temperatures, a weakened immune system, cuts on the body, bug bite, sunburn, and autoimmune disorders. Triggers can be identified potentially by keeping a track of symptoms and when they occur.
Symptoms of psoriasis vary from type to type. Each type of psoriasis displays a unique set of symptoms which are in a way characterized by skin lesions, flakes and itchiness.

The risk of being affected with psoriasis is higher for some individuals. The risk depends on the following factors.
The diagnosis is usually done through two methods. They are:
Treatment of psoriasis can be divided into four main types. They are topical treatments, light therapy medication and alternative medicine.
For patients with mild to moderate disease, topical application of creams and ointments can effectively treat the condition. For severe cases, this is used in combination with oral medicines or light therapy.
Topical treatment of psoriasis includes use of topical corticosteroids, vitamin D analogs, anthralin, topical retinoids, calcineurin inhibitors, salicylic acid, coal tar and moisturizers.
This treatment uses natural or artificial UV light to treat psoriasis. Exposing the skin to controlled amounts of natural sunlight also comes under light therapy. UV A and UV B lights are also used to treat psoriasis. Light therapies like narrow-band UVB phototherapy, Goeckerman therapy, psoralen plus UVA therapy, excimer laser therapy, etc. are well-known therapies that use light and its forms to treat psoriasis.
Use of oral and injected medication is necessary if a person has severe psoriasis or if he is resistant to other treatment types. This type of treatment is also called systemic treatment. Drugs like retinoids, methotrexate, cyclosporine, and other drugs that alter the immune system are used in treating psoriasis.
Apart from generic medicines that treat psoriasis, there are several alternative therapies that are proven to reduce symptoms of psoriasis. Such alterations include special diets, use of dietary supplements, herbs and creams. These treatments are not as effective as other treatment procedures but are considered safe for long-term usage. They are believed to ease symptoms like itching, scaling and pain. This treatment could be the best choice for patients with mild psoriasis.
Remedies like usage of aloe-vera, fish oil and Oregon grape are also well-known in treating psoriasis. Application of aloe-vera cream has shown to reduce scaling, itching and inflammation. This can be used on a repetitive basis and as required by the patient to see significant improvement. Omega -3 fatty acids that are found in fish oil also reduce inflammation associated with psoriasis. Topical application of Oregon grape which is also known as barberry has also shown to reduce inflammation and ease a psoriatic condition.
The measures that could aid in the prevention of psoriasis include –
No. Psoriasis cannot be passed by touching a skin lesion.
A person can develop psoriasis when his immune system sends wrong signals that lead to increases in skin cell production. The excessive cells pile up on the surface of the skin, leading to scaly patches that are itchy and painful.
Yes. Certain foods like processed meat, dairy product, red meat, etc. also trigger psoriasis.
Thick lotions and creams that seal the moisture are good for psoriasis treatment. Application of petroleum jelly, olive oil and other thick substances which keep the skin moist often help in treatment.
