Final answer:
Dumping syndrome can often occur after gastric bypass surgery, as food moves too quickly from the stomach to the small intestine, leading to symptoms such as nausea, diarrhea, and flushing.
Step-by-step explanation:
Dumping syndrome is a condition that can occur after certain medical/surgical procedures, most commonly after gastric bypass surgery. During this surgery, the size of the stomach is reduced, and the length of the small intestine is also shortened. As a result, food moves too quickly from the stomach to the small intestine, leading to symptoms such as nausea, diarrhea, and flushing. Despite these risks, benefits of bariatric surgery include substantial weight loss and improvements in obesity-related conditions. Therefore, the correct answer to your question is 1) Gastric bypass surgery.
