Stomach pumping is great for removing things from the stomach before they get absorbed, like poisons or drugs, and it can also be used to stop things from being digested. No, it's not a new form of bulimia; rather, it's a medical method of giving the rest of your digestive tract a break. If your intestines are blocked for some reason, such as a hernia, obstruction or impacted fecal matter, the last thing you want is any more of your stomach's contents filling up your intestines and increasing the pressure and pain. To help relieve pressure -- and to keep more from mounting -- gastric lavage is sometimes used to clear the stomach's contents before it moves through the rest of the digestive tract [source: University of Maryland Medical Center].
