Circumcision is usually done with absorbable threads, which fall off in about 1-2 months, but some individual patients may take longer to fall off, possibly more than 3 months, and each individual case is different. If it takes too long, it is advisable to go to the hospital you are visiting to have the stitches removed. The main reason for circumcision is the following: first, circumcision is recommended for patients with recurrent inflammation of the foreskin. Secondly, patients with circumcision are recommended to go for circumcision. In addition, patients whose foreskin is too long and affects urination are also recommended to go for circumcision. In the above three cases, circumcision can prevent recurrent inflammatory infections, keep the lower body clean and hygienic, and effectively reduce the incidence of penile cancer.
