ABOUT THIS SERIES

Americans spend roughly twice as much on health care as their counterparts in countries such as Germany, Canada, Australia and Japan, without having measurably better health. "Too Much Medicine?'' is an occasional series by Star Tribune medical writers that examines America's high-cost, high-tech health care system and explores simpler cures that, experts say, could serve patients just as well.
