Psoriasis – Everything You Should Know About This Skin Disorder

Prosiasis appears to be an autoimmune skin disorder in a result of which cells multiply up to 10 faster than under normal circumstances. That causes the skin to form bumpy red patches capped with white scales. These skin patches tend to be itchy, dry, red, and scaly. Actually, these red patches may be localized anywhere, but common locations include the knees, elbows, scalp, and lower back.

Even though proriasis cannot be transferred from one person to another, this disease sometimes occurs to the members of the same family. In most cases, this autoimmune disease appears in the early adulthood. It is not uncommon for the patches to heal and, then, come back to the person again throughout his/her life. In this article you can learn more about this autoimmune disease.

Symptoms

Depending on the type of psoriasis (read lower), its symptoms may vary. The most common symptoms of plaque psoriasis (this form of psoarisis happens in 85%-90% cases) include the following ones:

  • Red plaques of skin, capped with silver-colored scales (in most cases). Usually, these skin plaques tend to be painful and itchy. Sometimes they may even crack and bleed. In the most extreme cases, these particles will grow and merge, covering large skin areas.
  • Plaques of crust or scales on the scalp.
  • Fingernail and toenail disorders, such as nail-pitting and discoloration of nails. Sometimes nail may even crumble or get detached from the nail bed.

Types

As we have already pointed out above, there are currently 5 types of psoriasis. These are the descriptions of those types:

  • Plaque psoriasis. This is the most common type of psoriasis, which happens in 85% – 90% cases of people suffering from this disease. About the symptoms of this psoriasis type you can read right above. Unfortunately, this form of the disease can be lethal, since the extreme inflammation of the skin destroys the body’s ability to regulate temperature and perform its barrier functions.
  • Guttate psoriasis. This form of the disease usually occurs in the childhood or very young adulthood, causing small spots of red color, located predominately on the limbs and torso. Common triggers of this form include stress, tonsillitis, strep throat, respiratory infections, skin injury, taking beta-blocker and antimalarial meds.
  • Erythrodermic psoriasis. This disease type causes skin redness and shedding of scales in layers. Certain medications, infections and severe sunburn may cause this form of psoriasis. It has to be treated urgently or, otherwise, it can lead to the severe form of illness.
  • Inverse psoriasis. This form triggers bright red, shiny lesions, localized in the place where skin folds, such as the groin, armpits, and under the breast.
  • Pustular Psoriasis. This type of illness causes scaly, red skin that contains tiny pustules on the hands’ palms and soles of the feet.

Causes

Even though this is an autoimmune disease, there are a variety of possible causes of this illness. This means that you can at least try to minimize the risks. The possible causes include:

  • Genes. Genes, which are the particles of DNA, control different things in your body (such as color of hair or eyes). With psoriasis, genes that are responsible for the immune system mix up the signals and your body overproduces cells, thus causing inflammation and damaging itself instead of fighting the invaders.
  • Alcohol. Heavy drinkers have a higher risk of suffering from this illness.
  • Hormones. There is a connection of this disease to the hormone changes, whereas it usually appears in the puberty. Menopause is also a likely trigger.
  • Stress. Researchers consider that your immune system may respond to mental and psychological pressure in the same way it does to physical injuries.
  • Smoking. It is proven that smoking may make the risk of suffering from psoriasis twice as likely.
  • Meds. Certain medications (indomethacin, antimalarial meds, meds for high blood pressure and heart diseases) may make your psoriasis worse.
  • Infections. Strep infections are linked to causing or influencing the guttate psoriasis.
  • HIV. Psoriasis gets really bad in the early stages of this chronic disease.
  • Skin injuries (such as bug bites, cuts, scrapes or infection) may also trigger the illness.
  • Weather. The symptoms of psoriasis become worse in winter due to cold temperatures, less natural sunlight, and dry air.
  • Weight. Obese people have a higher risk of suffering from psoriasis.
  • Sunlight. For most people suffering from this disease, a bit of sunlight is actually good. But sunlight may also cause worsening of the symptoms for a few people. So, protect your skin before heading outside.
