What is Psoriasis – Causes, Home Remedies, Precautions

Psoriasis refers to a troubling skin condition characterised by symptoms like itchy areas on the skin and flaking. Although the causes of this inflammatory condition can be many, it is becoming increasingly common. The important thing to note is that psoriasis is an autoimmune condition wherein, the production of skin cells is accelerated and this leads to inflammation as well as itching. 

Psoriasis can occur on various parts of the body such as the scalp, knees, and elbows and around the mouth. It is also commonly associated with other medical conditions like diabetes and digestive issues.


Although there is still some ambiguity about the exact causes, there are four main causes outlined by medical practitioners for psoriasis.


Psoriasis can be a hereditary disease. Researchers state that there is a 10% chance of inheriting the genes for psoriasis. However, not everyone with those genes develops psoriasis. If someone in your family has a history then the chances of developing it increase slightly.


When the immune system tends to attack its own cells, several health conditions can arise. Psoriasis can be one of them. When experiencing psoriasis, the immune system becomes overactive. This leads to inflammation and redness of the skin. In most cases, psoriasis is seen as an autoimmune disease.

Other health conditions

The chances of developing psoriasis may increase if one is already suffering from the following:

  • Cardiovascular disease
  • High blood pressure
  • Cholesterol issues
  • Arthritis
  • Type 2 diabetes

Environmental conditions

Although, environmental conditions may not necessarily cause psoriasis, they can certainly aggravate it or trigger it. Dry and cold environments tend to trigger itching. Other environmental and outside factors like lack of moisture and skin injuries can lead to an outbreak. Excessive sun exposure or consumption of alcohol or other drugs can lead to flare-ups too. 


Psoriasis has very easily detectable symptoms:

  • Extreme itching
  • Dry skin flakes on the scalp.
  • Extremely brittle nails
  • Skin lesions – thatare extremely red and itchy.
  • Fungus on toes and fingernails
  • Dandruff patches on the scalp and other areas of the skin like armpits
  • Plaques of red skin
  • Crusts of skin which are white or silver in colour.

Instead of purchasing the pre-packaged aloe Vera gel, it is better to extract some at home and use it as a treatment. This is because pre-packaged gels may contain additives and other oils which will not prove helpful.
