11 Causes of Psoriasis You Should Know

There are a whole lot of skin diseases out there, and one of them is psoriasis. If you have ever noticed red, dry, scaly and itchy patches on your skin, then you seem to have a history of psoriasis. Psoriasis is a common skin condition that speeds up the life cycle of skin cells. It is a chronic one, and it often comes and goes. This disease causes cells to build up quicker than usual on the surface of the skin, and before you know it, you have dead cells accumulating and forming scales and red patches that are itchy and sometimes painful. Although this disease can appear on any location on the body, it commonly affects the knees, outside of the elbows or scalp. So many factors trigger psoriasis; some of those factors are:

1Weak Immune System

One of the causes of psoriasis is an infection. How does infection seep in? When your immune system is weak, you become susceptible to infection. Your immune system is your body’s defense against disease. It helps combat infection through some specific cells. One of such cells used by the immune system to fight infection is the T-cells. T-cells travel around the body to track down harmful germs, but in some situations that cause psoriasis, the T-cells mistake the skin cells for germs and then, they misfire or attack the skin cells. This causes inflammation and the accelerated growth of skin cells. [1]
