What causes dumping syndrome after gastric bypass surgery? Early dumping syndrome can occur because of the dense mass of food that gets dumped into your small intestine at an earlier stage of digestion. The intestines sense that this food mass is too concentrated and release gut hormones. Your body reacts by shifting fluid circulating in your bloodstream to the inside of your intestine. As a result, your intestines become fuller and bloated. Diarrhea often occurs 30 to 60 minutes later. In addition, certain substances are released by your intestine that affect heart rate and often blood pressure, causing many of the symptoms of early dumping. This can lead to lightheadedness or even fainting. Symptoms of late dumping happen because of a decrease in blood sugar level (reactive hypoglycemia). Reactive hypoglycemia is low blood sugar caused 1 to 3 hours after a large surge of insulin. You are more likely to have dumping syndrome if you eat a meal heavy in starches or sugars. The sugars can be either fructose or table sugar (sucrose). Insulin levels can increase to high levels, and then lower your blood sugar too much. 找到一些，你如果上网，还是能查到很多的
最困扰我们的问题就是她每次吃饭以后，总会感觉心跳加快（平时70左右，可以跳到100以上）人很虚弱非常不舒服，大概要持续一个小时左右，中饭和晚饭以后还会好一些，尤其是早饭后，这个症状非常明显。我一开始以为是因为没有了胃，血糖波动太大，就让她早上只吃蔬菜和鸡蛋，但是还是有这个症状。还有已经在少吃多餐了。 跪求万能的华人网，给些建议，为什么她会出现这个症状，以及饮食上应该注意些什么。万分感谢。
