Also known as late postprandial dumping syndrome. It refers to a series of hypoglycemic symptoms caused by excessively rapid gastric emptying after gastrectomy, where glucose is rapidly absorbed by the intestinal mucosa, leading to a sudden increase in blood sugar, which overstimulates the pancreas to secrete excessive insulin.

Symptoms typically occur 90 to 180 minutes after a meal (especially after consuming large amounts of carbohydrates), manifesting as extreme weakness, fatigue, dizziness, flusteredness, tremors, cold sweating, and in severe cases, impaired consciousness. Physical examinations show no significant positive signs. Plasma insulin levels before the episode are often 3 to 4 times higher than normal, while blood sugar levels drop significantly during the attack. A few cases may initially present with dumping syndrome, followed by postprandial hypoglycemia.

Patients are usually treated in outpatient clinics. Eat small, frequent meals, reduce starchy foods, and increase protein and fat intake. During episodes, drinking sugar water can relieve symptoms.
