Dumping Syndrome is a possible side effect / complication of bariatric surgery.
Dumping syndrome occurs when the stomach contents move through the small intestine too quickly. The symptoms of dumping syndrome may include heart palpitations, sweating, nausea, diarrhea, general weakness and faintness.
Dumping syndrome is usually associated with the consumption of sugary foods or sweets after a gastric bypass surgery. In her book The Patient’s Guide to Weight Loss Surgery, author April Hochstrasser explains that “[w]hen the body senses the sugar level rising, it dumps insulin to handle the load.” This is known as dumping syndrome.
