The future market for treatments in obesity is certain to be more fragmented than it is now. There will be more different types of treatments offered by drug companies, device companies, surgical procedures, and other options.
Recent market developments in the field of obesity have principally centered around the mixed signals put out by the FDA on obesity drugs.
