Scrambled eggs (so I have heard) raise your blood sugar a lot. I don’t know that for a fact though. I know they make me feel weird after I eat them.
Also, I’m sorry but I don’t understand the first part of what you said. What so you mean by 3U of carbs?
1 egg has approximately 0.6g carbohydrates, 62mg sodium, 187mg cholesterol and should have hardly an impact on bg levels. If you feel weird, would it be possible you need more carbs and could be low instead?
