As dead underlying cells reach the skin’s surface, their voluminous accumulation causes raised, red plaques that gets covered with white scales. This disease typically happens on the elbows, knees and scalp. Psoriasis can also affect the palms, torso and soles of the feet.

  1. Immune system: Our immune system helps to keep us safe from infections of viruses and bacteria but if something goes wrong then our system starts working the opposite. Researchers believe that the immune system is one of the reasons for psoriasis. When our immune system is working overactive then it creates inflammation inside the body. A large number of healthy cells are produced. These excess cells then start coming on the surface of the skin very quickly. These piled up skin cells you see on your skin is psoriasis. It is red in colour and causes inflammation in the skin.
  2. Hormonal changes: During puberty or menopause, this issue can be seen on the skin. If you are a pregnant woman, then there are chances of you getting psoriasis. Once the delivery is done, you might again see it on the surface of the skin.
  3. Alcohol: People who drink regularly are high on risk, especially younger men. It is also to be mentioned that alcohol also makes treatment less effective.
  4. Medications: Some medications like Lithium (which treats bipolar disorder and mental illness), high blood pressure medicines ( including propranolol, beta-blockers, ACE inhibitors, quinidine), Antimalarial medicines (including chloroquine, hydroxychloroquine, Plaquenil and quinacrine) may increase the chances for psoriasis more.
  5. HIV: Patients who are suffering from HIV are more prone to psoriasis. But, as soon as you start treatment for HIV, you will see yourself better.
