Call it Hyper-digestion, because the quickly infused high concentration of sugar into the digestive track (caused by our bypassed pyloric valve) creates a 'rushed' digestion and a flood of insulin which combined causes the symptoms of hot & cold flashes, pounding heart, extreme tiredness, and the faint feeling along with abdominal cramps, nausea & diarrhea.

What is Dumping? The name Dumping has been given to a collection of symptoms that occur after a meal in patients who have undergone certain operations upon the stomach.
The symptoms fall into two groups. One group consists of symptoms that appear to be definitely related to the digestive tract: the patient feels sick, their abdomen feels bloated, they experience borborygmi, (a word that means tummy-rumblings), and this combination of symptoms sometimes leads up to passing a bulky, loose bowel motion. The other group of symptoms is quite different. Patients feel tired and want to lie down, and this may progress until they actually feel faint and sweaty and are aware that their heart is thumping (palpitations).
What is the Cause?
The cause of the symptoms is that the stomach is emptying its mixture of food and gastric juice into the intestines at a rate that is greater than normal.
Normally, when food enters the stomach it mixes with the gastric juice and digestion commences. The valve at the lower end of the stomach, the pylorus, acts as a brake on stomach emptying, so that the mixture is allowed through only bit by bit. If the valve is removed by surgery, or its function reduced by paralysing the muscle that forms the valve, the mixture gushes through into the intestine and causes the symptoms.
