Endoscopists are medical professionals who specialize in performing endoscopy, a procedure that allows doctors to examine the interior of a patient's body using a flexible tube with a camera called an endoscope. This technique is commonly used to investigate issues in the gastrointestinal tract, but it can also be applied to other areas, such as the respiratory system or urinary tract. These specialists are trained to diagnose and treat various conditions, including inflammation, tumors, and bleeding. Endoscopists often work closely with other healthcare providers to ensure comprehensive patient care and may also perform therapeutic procedures, such as removing polyps or taking biopsies for further analysis.
