Eating a large amount of lychee on an empty stomach can lead to hypoglycemia. Lychee is a fruit with high sugar content and should not be eaten on an empty stomach. When a person has a relatively low blood sugar level on an empty stomach, eating a large amount of fruit with high sugar content will convert fructose into glucose, stimulate the pancreatic cells to secrete excessive insulin and lead to hypoglycemic symptoms such as fainting, nausea, coma and other symptoms. Therefore, it is recommended to eat fruits with high sugar content, such as lychee, usually half an hour after meals, and not too much at one time, because lychee is rich in fructose, and the fructose content in blood will increase significantly after consumption, and a large amount of insulin will be released rapidly, leading to insufficient blood sugar supply and hypoglycemic reaction. Clinical symptoms include dizziness, fatigue, sweating, dry mouth and other symptoms, and in severe cases may be coma, convulsions and even life-threatening, so the number of lychees must be controlled. What’s more, do not eat lychee on an empty stomach, just eat a few lychee within half an hour after a meal, which is conducive to the digestion and absorption of food and promote gastrointestinal motility.
