General Surgeon
A general surgeon is a specialist who is trained to diagnose, treat, and manage patients with a broad range of surgical conditions affecting almost any area of the body. However, general surgeons usually focus on surgical treatment of abdominal organs, such as the intestines, esophagus, stomach, colon, liver, and gall bladder. The surgeon establishes the diagnosis and provides comprehensive preoperative and postoperative care to the patient. They are often responsible for the management of the trauma victim and the critically ill patient.To become a fully licensed general surgeon, one has to complete 4 years of medical school and typically five years in a general surgery residency program.
