I actually dumped for the first time the other day at 6 months out. I knew I was pushing my carb limit but I did it anyway Yeah....wont do that again! Got shaky, sweaty, and I could actually feel my heart beating in my neck...lasted about 30 minutes then thankfully passed. That bite (or two or three) of banana pudding was NOT worth it!

I found a wiki article on it which I'll post a little bit below. I haven't really experienced it myself yet at 6 months out but I have been really uncomfortable after eating some really dense foods like chicken too quickly. I have avoided ice cream, sweets and high carb snacks like the plague since surgery as don't want to ever experience dumping.

from the wiki:

"Gastric dumping syndrome, or rapid gastric emptying is a condition where ingested foods bypass the stomach too rapidly and enter the small intestine largely undigested. It happens when the upper end of the small intestine, the duodenum, expands too quickly due to the presence of hyperosmolar (having increased osmolarity) food from the stomach. "Early" dumping begins concurrently with or immediately succeeding ingestion of a meal. Symptoms of early dumping include nausea, vomiting, bloating, cramping, diarrhea, dizziness, and fatigue. "Late" dumping happens one to three hours after eating. Symptoms of late dumping include weakness, sweating, and dizziness. Many people have both types. The syndrome is most often associated with gastric surgery.

Rapid loading of the small intestine with hypertonic stomach contents can lead to rapid entry of water into the intestinal lumen. Osmotic diarrhea, distension of the small bowel (leading to crampy abdominal pain), and hypovolemia can result.

In addition, people with this syndrome often suffer from low blood sugar, or hypoglycemia, because the rapid "dumping" of food triggers the pancreas to release excessive amounts of insulin into the bloodstream. This type of hypoglycemia is referred to as "alimentary hypoglycemia.""
