Question: I am a man who has been obese for many years. I’m 5-foot-9 and weight about 380. I’ve tried every diet in the world and am close to signing up for a gastric bypass. But now I am reading about a new diet pill called Qnexa that may soon be sold. Do you think I should delay surgery to see if this drug helps me?

Dr. Hibberd's answer:
The FDA's panel advisory committee has voted in favor to approve Qnexa for the treatment of obesity. The FDA will take into consideration this vote when they make their decision on approval or not, which is now expected in July. There are certain cardiovascular concerns. It is probable that post follow up studies will be completed in order to keep a watchful eye on any possible problems. Since you have had obesity for so long, it is likely that you already have co-morbid conditions associated with obesity. You must let your doctor evaluate your current overall condition and lab parameters to know the benefit of Qnexa in your case.
