Psoriasis – What it is, Symptoms and Treatments we should all know. In addition, psoriasis turns your skin cells into Type A over absorption: They grow about five times faster than normal skin cells. And your body cannot go on. The ancients accumulate rather than crumble, making thick, scaly, itchy spots.
Why do these cells get a little black? There are more things under the surface of this skin disease. Researchers think that something triggers your immune system. The exact reason is a mystery. But it is likely a combination of genetics and triggers.
What is psoriasis?
The Psoriasis is a common skin condition that accelerates the life cycle of skin cells. This causes cells to accumulate rapidly on the surface of the skin. Extra skin cells form itchy and sometimes painful red spots and scales.
The psoriasis is a chronic disease that usually comes and goes. The main goal of treatment is to prevent skin cells from growing so quickly.
There is no cure for psoriasis, but you can manage the symptoms. Lifestyle measures such as moisturizing, quitting smoking and managing stress can help.
What are the Causes of Psoriasis?
The cause of psoriasis is not fully understood, but is thought to be related to an immune system problem with T cells and other white blood cells, called neutrophils, in your body.
T cells typically travel through the body to defend against foreign substances such as viruses or bacteria.
But if you have psoriasis, T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection.
Hyperactive T cells also trigger increased production of healthy skin cells, more T cells and other white blood cells, especially neutrophils. These travel to the skin causing redness and sometimes pus in pustular lesions. Dilated blood vessels in areas affected by psoriasis create heat and redness in the skin lesions.
The process becomes a continuous cycle in which new skin cells move to the outermost layer of the skin very quickly – in days instead of weeks. Skin cells accumulate in thick, scaly patches on the surface of the skin, continuing until treatment stops the cycle.
Just what makes T cells malfunction in people with psoriasis is not entirely clear. Researchers believe that both genetics and environmental factors play a role.

The psoriasis often begins or worsens due to a trigger that you can identify and avoid. Factors that can trigger psoriasis include:
Infections, such as streptococci or skin infections.
Skin injury, such as a cut or scrape, an insect bite, or a severe burn.
Heavy consumption of alcohol.
Vitamin D deficiency.
Certain medications – including lithium, which is prescribed for bipolar disorder, high blood pressure medications such as beta blockers, antimalarial drugs and iodides.
What are the symptoms of psoriasis?
The signs and symptoms of psoriasis are different for everyone. Common signs and symptoms include:
Red patches of skin covered with thick silver scales.
Small points of scale (commonly seen in children).
Dry, cracked skin that may bleed.
Itching, burning or pain.
Nuts thickened, pitted or ridged.
Sore and stiff joints.
Psoriasis patches can range from some dandruff-like climbing points to large eruptions that cover large areas.
Most types of psoriasis go through cycles, burn for a few weeks or months, and then subside for some time or even in complete remission.
There are several types of psoriasis. These include:
Plaque Psoriasis: The most common form, plaque psoriasis, causes dry, raised and red skin lesions (plaques) covered with silver scales. Plaques can be scratchy or painful and there may be few or many. They can occur anywhere in your body, including your genitals and the soft tissues inside your mouth.
Nail Psoriasis: Psoriasis can affect nails and toenails, causing bites, abnormal nail growth and discoloration. Psoriatic nails can loosen and detach from the nail bed (onycholysis). Severe cases can cause nails to collapse.
Guttate Psoriasis: This type mainly affects young adults and children. It is usually triggered by a bacterial infection such as streptococci. It is marked by small water-shaped, water-shaped lesions on its trunk, arms, legs and scalp.
The lesions are covered by a thin scale and are not as thick as typical plaques are. You may have a single outbreak that recedes on its own, or you may have repeated episodes.
Inverse Psoriasis: This mainly affects the armpit skin, groin, under the breasts and around the genitals. Reverse psoriasis causes smooth patches of inflamed red skin that worsens with friction and perspiration. Yeast infections can trigger this type of psoriasis.
Pustular Psoriasis: This uncommon form of psoriasis may occur in scattered patches (generalized pustular psoriasis) or in smaller areas on your hands, feet or fingers.
It usually develops rapidly, with pus-filled blisters appearing just hours after your skin becomes red and soft. Bubbles can come and go often. Generalized pustular psoriasis can also cause severe fever, chills, itching and diarrhea.
Erythrodermic Psoriasis: The least common type of psoriasis, erythrodermic psoriasis can cover your entire body with a red rash that can itch or burn intensely.
Psoriatic Arthritis: In addition to inflamed and scaly skin, psoriatic arthritis causes swollen and painful joints, typical of arthritis . Sometimes joint symptoms are the first or only manifestation of psoriasis or sometimes only nail changes are seen.
Symptoms range from mild to severe, and psoriatic arthritis can affect any joint. Although the disease is usually not as disabling as other forms of arthritis , it can cause stiffness and progressive joint damage which, in the most severe cases, can lead to permanent deformity.
What are the treatments for psoriasis?
There is no cure for psoriasis , but there are many treatment options available to help you manage your symptoms on a day to day basis. Treatment for psoriasis will vary depending on the severity of the condition, but usually begins with topical creams or ointments such as:
Corticosteroids (e.g. Betnovate and hydrocortisone).
Vitamin D analogues (eg Dovonex).
Dithranol (e.g. Dithrocream).
It is also recommended that moisturizers and emollients be used daily to help keep the skin lubricated.
Other treatments include phototherapy, where ultraviolet light (UVA or UVB, depending on the severity of the condition) is bright in the affected areas, and – for very severe psoriasis – systemic treatments such as methotrexate.
