Lokman Hekim Istanbul Hospital holds both JCI accreditation and ISO 9001 certification. The bariatric surgery consultation includes a preoperative diagnostic workup in one visit. This process covers an initial examination, laboratory tests, and a preoperative endoscopy. It also features consultations with cardiology and pulmonary disease specialists to determine surgical suitability. An anesthesia specialist review is part of the package to assess patient safety. These assessments happen at a single facility to avoid separate appointments.
