The last couple of weeks, every so often, I suddenly have a feeling of severe nausea and then I start sweating profusely, all over. It lasts for about 10 to 15 minutes. I have no pain associated with it. No chest pain or discomfort, no arm pain and no shortness of breath. Lately, I have been a craving for candy and sweets that I haven t ignored. I do have a history of having a CABG x3. As of my last blood testing, I am not diabetic. Can an excessive intake of sugary sweets kick a person into hypoglycemia?
