Home > News > Endoscopy

An endoscopy is often required before weight loss surgery for several important reasons:


  1. Assessing Upper Digestive Tract: An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), allows the surgeon and medical team to thoroughly assess the condition of the upper digestive tract, including the esophagus, stomach, and duodenum (the first part of the small intestine). This evaluation helps identify any abnormalities or potential issues that may impact the surgical procedure.
  2. Identifying Structural Abnormalities: The endoscopy can detect structural abnormalities such as hiatal hernias, ulcers, strictures (narrowing of the digestive tract), polyps, or tumors. These conditions may need to be addressed before or during the weight loss surgery to ensure a safe and successful outcome.
  3. Preventing Complications: Identifying and addressing any potential issues before surgery can help prevent complications during and after the procedure. This proactive approach improves the safety and success of the weight loss surgery.
  4. Creating a Surgical Plan: The information gathered from the endoscopy can assist the surgeon in planning the surgical approach, such as where to place incisions and how to navigate the patient’s anatomy during the procedure.
  5. Patient Safety: Weight loss surgery is a significant medical intervention, and ensuring that the patient’s digestive tract is in optimal condition before surgery is crucial for their safety. Detecting and addressing any issues early can reduce the risk of postoperative complications.


It’s important to note that the specific requirements for an endoscopy before weight loss surgery can vary depending on the type of surgery, the surgeon’s preferences, and the patient’s medical history. Patients should have a thorough discussion with their healthcare team to understand the reasons for the endoscopy and how it fits into their overall pre-surgery evaluation and preparation.
