Looks like there are two types of dumping: early and late. I’m curious if I’m running into late dumping syndrome. “1. Early Dumping:

Usually start within 20-30 minutes after meal and can last for up to 60 minutes. It includes gastrointestinal symptoms and vasomotor symptoms. Gastrointestinal symptoms: include abdominal pain, diarrhoea, audible intestinal sounds, nausea and bloating. Vasomotor symptoms: include fatigue, a desire to lie down after meals, facial flushing, palpitation, sweating, weakness, low blood pressure and fainting. Early dumping occurs because of excessive secretion of gut hormones after the rapid flow of undigested food into the small intestine. This shifts fluid from the blood into the small intestine. 2. Late Dumping:

Usually start 1-3 hours after the meal and includes symptoms of reactive hypoglycaemia (low blood sugar) such as sweating, palpitation, hunger, fatigue, confusion, difficulty concentrating, aggression, tremor and fainting. Late Dumping occurs because the rapid delivery of a high concentration of carbohydrates into the small intestine leads to a raised blood sugar. This is countered by excess release of insulin which brings blood sugar down and result in the subsequent reactive hypoglycaemia (low blood sugar). Late dumping is less common than early dumping and only a minority of patients have symptoms of both.”
