An upper endoscopy (Esophagogastroduodenoscopy or EGD) is a common outpatient procedure where a physician examines the lining of the upper gastrointestinal tract. A thin, flexible tube equipped with a light and camera is gently passed through the mouth to inspect the esophagus, stomach, and the first section of the small intestine. Patients often have logistical questions about preparation, including what to wear. Understanding clothing requirements ensures patient comfort and allows medical staff the necessary access for monitoring and successful completion of the exam.
Clothing and Metal Restrictions
Most facilities require the removal of all personal garments from the upper body before the endoscopy, including most types of bras. This restriction is necessary to attach various monitoring devices directly to the skin of the chest. Medical staff continuously track vital signs, including heart rhythm via electrocardiogram (EKG) leads, blood pressure, and blood oxygen saturation.
Metallic components, such as underwires, clasps, hooks, or zippers, interfere with the clear placement and reliable functioning of EKG electrodes. Additionally, procedures involving electrical instruments carry a slight safety risk where metal objects could conduct current. Although non-metal sports bras may sometimes be permitted, staff usually request the removal of all upper-body garments to ensure unrestricted access to monitoring sites. Leaving all jewelry and body piercings at home is also recommended due to these safety and interference considerations.
Recommended Attire for the Procedure
Since patients must change into a hospital-provided gown, clothing worn to the facility should prioritize comfort and simplicity. Loose-fitting garments are highly recommended, such as sweatpants, warm-up suits, or pajama-style bottoms that are easy to remove. Selecting an easily removable top, like a zip-up hoodie or a button-down shirt, simplifies changing into the gown.
Patients should wear comfortable, flat shoes, as the effects of the sedation make walking and balancing more difficult immediately after the procedure. Because of the sedation, a responsible adult must drive you home, and your outfit should be simple to put back on while you are still feeling groggy. Leave all valuables, including watches and rings, at home to prevent loss during changing and recovery.
Monitoring and Garments During the Endoscopy
Once you are brought into the preparatory area, a nurse will typically ask you to undress and put on a clean hospital gown, which is designed for easy access and patient dignity. This gown provides the medical team with an unobstructed area on your chest to place the necessary monitoring equipment. The standard practice involves attaching EKG leads, which are small sticky patches, to specific points on your chest to monitor the electrical activity of your heart.
A blood pressure cuff will be placed on your arm, and a pulse oximeter, which measures oxygen levels in the blood, will be clipped onto a finger or toe. The gown facilitates the quick and accurate placement of these devices, which are constantly monitored by a dedicated staff member throughout the procedure. Your personal clothing will be stored securely in a designated locker or bag in the pre-procedure area. Once the endoscopy is complete and you have recovered sufficiently, you will be assisted in changing back into your comfortable clothing before being discharged.
