Psoriasis is a common skin disease with a high clinical incidence and a wide age distribution, with children, middle-aged people and the elderly all having a distribution. The incidence of psoriasis is high, with a wide age distribution, including children, middle-aged people and the elderly. Can psoriasis be cured? In other words, the skin lesions of psoriasis can be cured, but just like a headache or cold, it does not mean that psoriasis will never recur. Is psoriasis contagious? Psoriasis is not contagious, but it is a hereditary skin disease. If both parents are psoriasis patients, the chances of the next generation being psoriasis patients are 50%-66%, and if one parent is a psoriasis patient and the other is not, the chances of their next generation having psoriasis are 16.4%. This means that psoriasis is associated with heredity, but not that it will necessarily be passed on to the next generation. Is it true that pregnancy can only be considered after the psoriasis lesions have been cured? Some people with psoriasis believe that if they don’t get rid of their psoriasis lesions, they will pass the disease on to the next generation if they get pregnant. The reason is that even if we get rid of the psoriasis lesions, the genes related to the development of psoriasis still exist in our body, and our treatment will not change the mutated genes in our body at the moment. In other words, whether our skin lesions exist or disappear has no effect on the chances of psoriasis occurring in our next generation, which means that the existence of psoriasis skin lesions has no effect on the preparation for pregnancy, but on the contrary, the medication used to treat psoriasis may affect pregnancy.
