Dr. Bradshaw: Gastric bypass surgery will provide sustained health and weight-loss benefits in morbidly obese patients, since it allows morbidly obese patients to have the size of their stomachs reduced to allow them to consume less food, and also allows food to bypass part of the small intestine, ensuring that fewer calories are absorbed. Morbidly obese patients will realize more sustained benefit from gastric bypass surgery than any other treatment regimen could provide. Dr. Hobbes: Not so. Gastric bypass surgery might help morbidly obese patients initially. However, patients undergoing this surgery will eventually become extremely dehydrated and deprived of critical nutrients needed to maintain their health due to the vastly decreased amount of food and beverages they can consume. Eventually, most will develop severe complications from dehydration coupled with nutrient loss. Hence, sustained health benefits will not be obtained. Which one of the following is the point at issue between Dr. Bradshaw and Dr. Hobbes? ['whether the technology of gastric bypass surgery will benefit patients in the long run', 'whether gastric bypass surgery in general is more beneficial to health than other health care plans', 'whether gastric bypass surgery should be used for all morbidly obese patients', 'whether gastric bypass surgery is likely to be widely undergone by morbidly obese patients in future years']
