New Jersey Gov. Chris Christie's secret gastric band surgery in February has stolen front-page headlines today. His weight is often the target of comedic fodder, but it was a legitimate concern surrounding his overall health.

This news has gotten the political media stirring that the governor is planning a White House run in 2016, but here at the Fool we're more concerned with investing than with politics. With more than 200,000 stomach-shrinking procedures performed per year, is there money to be made for investors?

In this video, Motley Fool health-care analyst David Williamson takes a closer look at the companies and highlights why this may be no slam-dunk for investors.
