Is it possible to have really low blood sugar with raynauds, I mean, my rays is bad most of the time, but recently it seems to get worse when I'm low on blood sugar. For example, I went to the hospital 5o visit my nan the other day, I all of a sudden went all light headed, I told my mum, went to the toilet and was fine again, 5 minutes down the line, it happened again, this time my nan, who was really ill, noticed, and said to me to have a banana, then cos I was practically fainting, I agreed, about 20 minutes later and I was fine, due to the slow energy release. Please help, it's affecting my day to day life a lot now. And yes I know, when I go back to school I will be going to the Dr....thanks!!
