Heavier Patients May Require Longer Needles

Researchers have detected a problem with medicine administered in a traditional way: The doctor tells you to bend over, and you get a shot in the rear. Irish researchers at a meeting of the Radiological Society of North America warn that as more patients get more obese, the needles are not long enough. They can't penetrate the layers of fat. In a small test, most patients did not receive medicine in the proper place, so the researchers are suggesting longer needles.
