Final answer:
The option 'Development of new eating habits' is NOT a reason that bariatric surgery fails to achieve long-term weight loss. Chronic diarrhea and vomiting, stretching of the stomach pouch over time, and psychological factors are potential reasons for lack of sustained weight loss after surgery.
Step-by-step explanation:
The correct answer to the question is c) Development of new eating habits. This option is not a reason that bariatric surgery fails to achieve long-term weight loss for most people. In fact, the development of new eating habits can be a factor in the success of bariatric surgery. Following the surgery, patients are typically advised to adopt a healthier lifestyle, which includes eating habits that can assist with long-term weight maintenance. The other options listed—chronic diarrhea and vomiting, stretching of the stomach pouch over time, and psychological factors impacting eating behaviors—are potential reasons for the failure to maintain weight loss post-surgery.
Option a), chronic diarrhea and vomiting, can be side effects of the surgery that lead to malnutrition and dehydration rather than sustainable weight loss. Option b), stretching of the stomach pouch over time, is a physiological change that can occur after surgery, which may allow for increased food intake and result in weight gain. Option d), psychological factors impacting eating behaviors, can include emotional eating or unresolved issues relating to food and body image, which can contribute to weight regain if not addressed properly.
