It is necessary to provide a medical certificate from your endocrinologist attesting to the severity of the disease, stability of hormonal levels and lack of contraindications to the procedure. You have to bring the certificate with you to the examination. On the basis of the examination results and the certificate from the endocrinologist the doctor will decide whether you can be qualified for the surgery and, if so, which correction method will be the most suitable in your case. If your treatment includes medications from the isotretinoin group, it is recommended to schedule the surgery at least three months after the treatment termination.
