Before the surgery, a consultation is made between the surgeon and the patient. The patient’s weight, body mass index, health issues, medical background, and such information are obtained at first. Relevant tests are ordered, and the patient's general health status is observed. Psychological screening is another important part of this operation. Since big life changes await the patient after the surgery, she/he must be ready both psychologically and emotionally.
Through the results of all these, it is decided whether the patient is suitable for surgery. If everything goes well, the operation date is determined. The doctor may want the patient to take some pre-surgery actions.
