summary

Recently, I always feel itching on my back. I wake up from itching when I go to bed every day. I keep scratching with my hands, but it's broken. Later, I found something abnormal. I went to the hospital to check it. The result is psoriasis. Let's learn the etiology of psoriasis.

What are the causes of psoriasis

The first reason is: endocrine: hypocalcemia is a cause of generalized pustular psoriasis. Although vitamin D3 derivatives can improve psoriasis, vitamin D3 deficiency does not cause psoriasis. Psoriasis improves in 50% of pregnant women. But some pregnant patients will have eruptive pustulosis (some think it is also a kind of pustular psoriasis).

The second reason is: infection: especially bacterial infection, can induce or aggravate psoriasis. Infection can be found in 45% of psoriasis patients. Streptococcal infection, especially pharyngitis, is the most common cause. Streptococcus can be isolated from periodontal abscess, perianal cellulitis and pustules.

The third reason is trauma. Psoriasis lesions often have an inseparable relationship with trauma, such as bruises, injections, insect bites, burns, scalds and scratching, which can cause skin damage. Once the skin damage, it will induce the occurrence of psoriasis.

matters needing attention

In daily life, patients with psoriasis need to pay attention to keep the skin clean and disinfected, change the sheets and underwear regularly, keep the clothes clean and soft, and keep the air fresh and circulating in the living space, so as to prevent the skin from further infection.
