Hypoglycemia and the sleeve in Gastric Sleeve Surgery Forums Posted July 29, 2016 I have been craving sweets and carbs the last month like crazy. I was disappointed in myself and didn't understand how I suddenly couldn't resist these things. Today I decided to check my blood sugar about an hour after eating because I felt just awful. My blood sugar was at 52. I have been googling and searching to see what would cause my blood sugar to drop and me not being diabetic. In a comment in one article it stated that weight loss surgery can cause reactive hypoglycemia because the carbs go straight to the intestines. Has anyone else experienced this problem?
