If you have problems with low blood sugar that is called hypoglycemia. Anybody can become hypoglycemic, especially if they aren't eating enough or have a high metabolism. You could talk to your doctor about your specific situation but it sounds like your nurse already gave suggestions about eating more often to keep your sugars up to a normal level. Good luck
low blood sugar is not the same as gestational diabetes. however even with gestational diabetes you can have low blood sugar. but it's not the same thing
