accelerated gastric emptying
Abnormally rapid transit of gastric contents into the small intestine, often occurring after restrictive bariatric procedures.
Full Definition
Accelerated gastric emptying refers to the rapid passage of food from the stomach to the duodenum, which can occur as an adaptive mechanism following restrictive bariatric surgeries like sleeve gastrectomy. This altered physiology contributes to early satiety, improved glucose homeostasis, and activation of incretin hormones. While often beneficial for weight loss and metabolic improvement, it can also lead to postprandial symptoms and nutritional challenges. The mechanism involves both anatomical changes and altered gastric accommodation patterns that affect normal digestive timing.
Usage
Usage note: Distinguish from dumping syndrome, which involves specific symptomatology rather than just physiological timing changes.
