Adrenocorticotropic hormone is not a disease but a hormone, mainly referring to glucocorticoids, which are mainly used to treat connective tissue diseases and autoimmune related diseases. There are diseases of the body called connective tissue diseases, represented by systemic lupus erythematosus and rheumatoid arthritis, as well as immune-related diseases such as chronic nephritis, nephrotic syndrome, and so on. These diseases are currently thought to be caused by immune disorders in the body that produce many antibodies that attack the target organs. In this case, the application of antibiotics or other medications is not effective, and only hormones can be applied to treat the condition, that is, adrenocorticotropic hormones. This hormone has the ability to suppress the body’s overwhelming immune response, thus achieving the goal of protecting the organs. However, this hormone can also produce side effects in the process of application, such as peptic ulcer, obesity, osteoporosis, and in some severe cases, femoral head necrosis may occur, so it must be closely monitored in the process of application.
