Causes and signs of psoriasis

Psoriasis examination by a doctor

Psoriasis- The disease is manifested by the appearance of a pink, silvery scaly patchy rash, often accompanied by itching. However, this is only the tip of the iceberg. At the heart of the disease are processes that are not fully understood.

Psoriasis is a mysterious enemy

In psoriasis, skin cells begin to divide 6 to 10 times faster than normal. This leads to chronic inflammation and flaking of the skin.

Scientists have studied psoriasis for decades, but there is no clear answer to the question "Why does psoriasis appear? " Modern science still does not. The disease is not contagious but can be passed on. Exacerbation can be caused by many external and internal factors: stress, skin trauma, use of certain medications (usually antibiotics), alcohol abuse, infectious diseases (streptococcal, viral infections)), v. v.

The manifestations of psoriasis are variable: the surface of the lesion can be dry or teary, and different parts of the body can be affected. Some patients have knees and elbows, others have palms and soles, and others have large folds of skin or mucous membranes or nail plates. Sometimes psoriasis affects a very large area of the body, sometimes it is confined to limited areas and never spreads further.

It is no exaggeration to say that psoriasis is one of the most mysterious diseases. Scientists have figured out exactly what happens in the body of a patient with psoriasis and how to alleviate his condition, but it is still not clear what causes pathological changesthese and how they can be prevented.

Winston Churchill has struggled with psoriasis his whole life and promises to erect a golden monument to a doctor who will solve the mystery of the disease and find an effective treatment. Alas, the prize never found its owner.

Why does psoriasis appear?

Science does not know the exact reason, however, over the years of studying the matter, several hypotheses have been formed:

  • autoimmune theory. It is all due to an increase in the concentration of T lymphocytes, which leads to ongoing inflammation in the affected skin. The body seems to begin to perceive its own skin as an invader.
  • The genetic theory that explains psoriasis is a defect in the DNA.
  • According to the endocrine theory, psoriasis occurs due to dysfunction of the endocrine system, namely the pituitary gland and thyroid gland.
  • exchange theory. Scientists have found that psoriasis patients have problems with lipid and nitrogen metabolism, as well as increased levels of toxins in the body.

All of these theories have a right to exist, but so far none have been fully proven. Therefore, modern psoriasis treatments aim to reduce the severity of symptoms, reduce the likelihood of disease recurrence and improve the overall body.

Symptoms similar to those of psoriasis were described in detail in ancient Roman medical treatises. In those days, however, psoriasis was often confused with other skin diseases of entirely different origins. For the first time, psoriasis was recognized as an independent disease only in 1799, and as a non-communicable disease - only at the end of the 19th century.

Who is affected?

Psoriasis doesn't discriminate - both women and men get it equally. Psoriasis typically appears at a young age - peaking between 15 and 25 years of age. However, if you didn't have psoriasis in your youth, this doesn't mean the danger is over - sometimes the first symptoms of psoriasis appear between the ages of 50 and 60. The good news is that people who develop psoriasis later in life have less severe psoriasis. According to WHO, if one of the parents has psoriasis, the risk of developing the disease in the child is about 14%, and if both - 41%. However, children of parents who have never experienced this nuisance also develop psoriasis. Statistically, psoriasis usually affects people with dry, thin skin.

The first symptoms of the disease

Psoriasis begins unrecognizably: in the early stages of development, the disease affects small areas of the skin, usually on the folds of the limbs, scalp and along the hairline. Sometimes the first manifestations of psoriasis occur at the site of persistent mechanical irritation of the skin, or in other words, where clothing rubs and rubs. At first, a person feels itching and a feeling of tightness in the skin, then small islets appear on the red and flaky skin. On these pimples appear gray scales of dead skin, like wax crumbs, which are easy to separate. Sometimes such patches become wet, forming yellowish lamellar scales on their surface. When the second part is removed, a bleeding surface is exposed. Gradually, the patches of warts grew and linked together, affecting more and more on a large scale.

Signs of psoriasis of different types

There are several types of psoriasis:

  • seborrheic psoriasis. Most commonly occurs on the scalp. It manifests as itching and peeling of the skin, spreading to the area behind the ears and the skin along the hairline.
  • exudative psoriasis. With this type of psoriasis, the affected areas of skin not only peel, but also become moist, and the surface of the papules appears as yellow scaly patches (hives caused by a rash).
  • Psoriasis between episodes. More typical for children. In this type of psoriasis, the patches are bright red with little or no peeling. Sometimes the patches get wet. Parents often confuse this type of psoriasis with diaper rash.
  • systemic psoriasis. Occurs on the soles of the feet and palms. It is manifested by thickened, dry, cracked skin.
  • Chronic psoriasis is manifested by large patches that do not go away for a very long time, sometimes tumors appear - warts and papillomas.
  • Rupioid psoriasis is a form of chronic psoriasis. On the plate appeared crusts, and gradually the plate was higher, having a conical shape.
  • Intestinal psoriasis is characterized by a multiple rash consisting of many small papules.
  • Psoriasis of the nail plates (psoriatic onychia) causes deformity of the nails, the appearance of yellow-brown spots under them. A common type of psoriasis, occurring in 25% of patients with this condition.
  • Mucosal psoriasis affects the oral cavity and causes papules to appear on the mucous membranes.

Frequency of psoriasis manifestations

The course of psoriasis is cyclical. In the advanced stages, itchy patches or a small rash appear, which gradually coalesce into a single spot. After 1-4 weeks, the spread of the patches stops, they are covered with silvery scales. This is called the static phase. This is followed by a regressive phase, when the plaques gradually disappear. However, do not be deceived - this does not mean at all that the recovery has come. If psoriasis isn't treated, things will start all over again, and after a while, the episodes will start to shift and flares will become almost monthly.

Psoriasis can and should be treated. If not promptly applied measures, psoriasis will quickly turn into a chronic stage, extremely difficult to cure. To treat psoriasis today, it is common to use medical methods, physical therapy as well as topical drugs - ointments, creams for psoriasis, the effectiveness is quite high.

However, it should be noted that before starting any psoriasis remedy, you should consult your doctor. At least because a non-expert cannot make a diagnosis on their own.
