There are plans to increase facilities for obese people in Cornwall and the Isles of Scilly to have gastric band operations on the NHS.
The NHS in the South West has said it plans to increase the number of centres offering bariatric surgery in the region from two to six.
It has proposed siting one of the new centres in Cornwall.
Bariatric surgery involves the fitting of gastric bands and gastric bypasses for the morbidly obese.
The proposal was put before Cornwall Council's overview and scrutiny committee earlier but still needs to be approved.
Steve Moore, from NHS Cornwall and Isles of Scilly, said: "We're delighted that more specialist services can be offered to patients in Cornwall as a result of this work."
Louise Tranmer, director of the South West specialised commissioning group, said: "We feel this solution will meet patient need now and into the future."
Bariatric surgery is only offered to people with a body mass index of at least 40 and when other attempts to reduce obesity have failed, the NHS trust said.
