Circumcision can still be beneficial later in life if a fat child is circumcised or circumcised. The foreskin is the skin on the periphery of the penis and has a certain degree of ductility. When the penis is weak, it may encircle the coronal sulcus and glans, and when it is erect, the foreskin retracts, revealing the glans and coronal sulcus. Some children, especially fat guys, are relatively easy to have a long foreskin, circumcision, etc. In addition, due to obesity, the foreskin tissue accumulates in the local area, may not be able to reveal the glans and the coronal sulcus. In this case, fat kids are prone to foreskin scaling, prone to conditions such as prepuce glans, and may also induce urinary tract infections such as urethritis and other lesions. At the same time, due to the abnormal foreskin, it may also hinder the normal development of the genitals, which has an impact on the life of the affected children. After diagnosis of the specific condition, early surgical treatment to remove the excessively long foreskin tissue, revealing the glans and coronal sulcus, to ensure the normal development of the penis, but also to reduce the incidence of infectious lesions, is beneficial to the child.
