Why Psoriasis occurs?

 By: Cyril Wee
Psoriasis is a skin ailment that affects almost 3% of the entire global population. The disorder is characterized by flared up red patches covered by silvery flakes. These patches can be seen on the surface of the skin and at times can be found on the scalp. You must be wondering why psoriasis occurs? Well, the exact reason behind this skin disorder cannot be pinpointed but there are actually quite a number of factors listed under why psoriasis occurs. You also need to understand there are several variations of the disease but there are a few causes responsible for the most common variants.

Causes of psoriasis

To your question why psoriasis occurs, the first answer will be genetic causes. It has been found that there are about 9 gene mutations behind why psoriasis occurs. One of these mutations is on chromosome 6 and it is known as PSORS-1. This is thought to be the primary reason behind psoriasis. So what exactly happens? Mutation of the genes leads some of the cells in your body to function differently-the cells start to do things that they should not. In case of psoriasis mainly the T-helper cells are affected by mutation.

The second answer to the question why psoriasis occurs is the immune system and it can be asserted here that this is the most important cause behind the occurrence of psoriasis. It has to be made very clear it is a malfunctioning immune system and that alone is the reason behind why psoriasis occurs. When your immune system functions normally the white blood cells manufacture antibodies that fight against foreign invaders like virus and bacteria. However in case of psoriasis a special kind of white blood cells by the name of T -cells becomes overactive. They start working overtime.

Are you wondering why psoriasis occurs when these T -cells go on an overdrive? Well, the overactive T -cells actually attack your skin and this in turn sets off a series of events. This further leads to multiplication of skin cells at such a rapid rate that they start to stack up on the surface of your skin. Herein lays your answer to why psoriasis occurs. Where it takes about 30 days for normal skin cells to form, reach maturity and then slough off in case of the psoriasis plaques the entire process takes a maximum of 6 days. This is how rapid the cell formation is.

When you look for answers to why psoriasis occurs there is something you will need to keep in mind. T -cells in themselves are not harmful as they produce chemicals that aid in healing your skin. However in psoriasis these T-cells produce the chemical in large quantity and this leads to inflammation in the joints and skin surface. Certain environmental causes can also be listed under why psoriasis occurs. It has been seen that all people who have gene mutations are not affected by psoriasis. There are specific environmental conditions that trigger the occurrence of psoriasis.

Psoriasis is a non-infectious and a chronic inflammatory disease of skin. The appearance of red well-defined plaques with a silvery scale is considered as a classic symptom of this disease. The extensor surface of the body and scalp are the most common areas where these plaques can be found, indicative of the occurrence of psoriasis. There are two groups of this disease, depending upon the age group affected. Most patients choose natural treatment for psoriasis like Ayurvedic medicine as these natural remedies have given the best results.
Psoriasis is one of the worst skin rashes that one can have. Psoriasis is a chronic autoimmune disease that will cause the skin to thicken and redden, making flaky patches commonly known as skin scales. This is brought about by an accelerated growth of skin cells that rise up to the epidermis, the upper layer of the skin. Under common conditions, skin cells grow deep within the skin and normally rise to the surface about once a month. This rapid expansion in skin cell growth is brought about by the body's immune system emitting faulty signals that double their growth to two weeks as opposed to the healthy rate of four weeks.
Salts is also unique. The salt in ordinary sea water is sodium chloride, or common salt. The Dead Sea, on the other hand, contains a smaller proportion of sodium chloride, with the balance consisting of magnesium, potassium and calcium chlorides and a comparatively high concentration of bromides. Researchers believe that the therapeutic properties of the Dead Sea are due to the presence of these other salts, mainly those of magnesium, potassium and bromide. Millions of Americans suffer from the symptoms of psoriasis.
