I am rethinking my response about using sugar for low numbers or feeling faint. With diabetes, a sugary drink or orange juice has long been the remedy for active people whose sugar levels drop and they need a quick fix to keep from passing out. I forgot that diabetes has low numbers and high numbers, depending on how well the insulin system in your body is working, and how active you are. People on a long hike can run low on sugar for energy. In this case, a liquid or snack bar can be a quick fix. You need to see an endocrinologist as we are not experts, and everyone is different.
