Most patients with SLE, ankylosing spondylitis, and some patients with rheumatoid arthritis start at a young age, and most of them have the desire to have children. Many patients have expressed to me the concern that they are afraid of inheriting the disease after having children. I hope that this article will help to clear the clouds of doubt and dispel concerns. 1. These diseases are not 100% hereditary (this explains the confusion of some people: why do they have the disease when their parents do not?) This explains the confusion of some people: why do they have the disease when their parents don’t? The chances of actually passing it on to the second generation are low. The perception of the chance of inheritance varies from region to region, from time to time, and from unit to unit. According to the author, the chance of SLE being passed on to the next generation of girls is less than 1.5%, and the chance of it being passed on to boys is even lower. The chance of passing on ankylosing spondylitis to the next generation of boys is about 10-20%. It can be said that the chances are relatively low. 2, “genetic factors” is a congenital condition, but the majority of rheumatic immune diseases require a lot of acquired conditions (mainly refers to the conditions of daily life, learning, work and environment). After the birth of a child, in life and other aspects of attention, can reduce the chances of the above-mentioned morbidity. 3.What if the child is really sick? At that time, you will have knowledge of the disease, knowledge and vigilance, so you can detect the disease early and not delay the diagnosis, “early detection and early treatment” is the nemesis of rheumatism. More importantly, medical development is fast, the future treatment effect will be better than now, part of the rheumatic disease may be treated as a minor disease later. 4, in fact, most chronic diseases, such as hypertension, diabetes, stroke, gout, various rheumatic diseases, and even many cancers, etc., will have a little genetic predisposition (i.e., offspring relatives are more likely to get the disease than ordinary people). These people all have children and grandchildren. Various chronic diseases accompany human evolution and development, and are a normal part of human society. “Fear of rheumatism hereditary, so you don’t have one” is equivalent to choking.
