Final answer:
Liposuction is the correct answer, which is a cosmetic procedure to remove fat, unlike bariatric surgery, which is for weight reduction and involves altering the digestive system.
Step-by-step explanation:
The removal of excess fat deposits in specific areas of the body with the use of a cannula inserted under the skin is known as liposuction. This procedure is different from bariatric surgery, which is recommended for cases in which a person has had no success with dietary and exercise attempts to reduce weight or is at risk for death due to obesity. Bariatric surgery involves altering the gastrointestinal system to limit food intake and/or absorption, which may be more effective than non-surgical treatments for obesity in the short term. However, as of the last update on research, long-term studies on the effectiveness of bariatric surgery still need to be conducted.
