The symptoms of dumping syndrome are most generally experienced immediately following a meal, although in some individuals, symptoms are delayed for up to 3 hours after meals. In a number of individuals, early and late symptoms are observed, notes Mayo Clinic.

The cause of early phase dumping syndrome, according to WebMD, include the stretching of the small intestine, the release of hormones into the small intestine and water being pulled from the bloodstream into the small intestine. Late phase dumping syndrome is generally accompanied by feelings of shakiness or dizziness, a rapidly pounding heart, mental confusion, loss of concentration, flushing, sweating, fatigue and hunger. This phase is caused by a rapid elevation and decline in blood sugar levels, and for this reason, it may be worsened when eating simple carbohydrates and sweet foods.
