Would a gastric bypass interfere with having your stomach pumped?

Yes, a gastric bypass can interfere with having your stomach pumped. This is because the procedure involves surgically altering the digestive system by decreasing the size of the stomach, creating a smaller pouch to hold food and restricting or rerouting part of the small intestine. As a result, it changes how food moves through your digestive tract, making it harder for substances to enter and leave your stomach. That said, doctors are still able to perform medical procedures like stomach pumping in people who have had gastric bypass surgery if they decide that doing so is necessary. In such cases, they'll usually substitute alternative methods that don't involve accessing the digestive tract directly (such as via an endoscope), allowing them to pump out whatever material needs to be removed without interfering with any changes made during surgery.
