NBC's Al Roker reports on his health since his gastric bypass surgery, and the potential dangers and benefits involved in the procedure, in an hourlong special to air tonight on "Dateline NBC."
Roker, the weatherman on the network's "Today" show, underwent gastric bypass surgery 2 1/2 years ago.
"For anybody who thinks that this is a magic bullet — you do this and it's done. You're making a mistake. It's not," he says.

In the four-part report, "Weighing the Risks," Roker talks to teens, parents and a physician about some possible dangers, and whether teens have a tougher time dealing with emotional and physical changes that come with the surgery.
