Low blood sugar? Something else?

[winneythepooh7]

OK so I went to my doctor tonight for a routine physical/bloodwork. Everything was fine until I got up to leave. I felt really dizzy and passed out for about 5 minutes. I came to, and had no clue where I was/what was going on. The bizarro thing was my doctor told me I was having what appeared to be a seizure while I was passed out. A year ago, when I went for a physical she told me that my blood sugar level was low, but nothing to worry about. I just did a quick search online and saw that the seizure could be a result of low blood sugar. I am going back in two days to see her but I am slightly nervous cuz nothing like this has ever happened to me before. There is a history of diabetes in my family as well so I am kind of nervous about that. Has anyone ever experienced anything like this before? By the way, I did eat two meals today as well, so I wasn't totally "fasting" all day.......
