Hi there. I have been hypoglycemic for 15+ years and had a baby 6 months ago. While pregnant, I had gestational diabetes and went to a nutritionist to learn how to manage things while pregnant. I learned so much about my blood sugar that I didn't know all these years.
Here's the basics - I may not have the timings exactly right, but you will get the idea. Carbs are quick energy and last in your system for an hour or two. About the time that your sugar is going down from the highest point of the carbs, the protein kicks in. Protein takes longer to enter the system, doesn't raise sugar as much as carbs, but stays around longer. The last thing to come into play is fats. They come into your system even later, don't raise sugar very much, but the effects last a long time. So... you need all of them to keep your sugars stable.
And Hypoglycemia and diabetes are different - that's why diabetics don't know about the protein need for hypog's!
I was always told not to eat simple sugars - regular sweets, soda, etc - because it would raise my sugar too high, then I would crash down too low. (My insulin would kick in to deal with the sugar, then not shut off when it should.) So I used to check labels for sugar amounts. The nutritionist said I should be looking at overall carbs, not just the sugar part.
Small meals were good for me, but hard to do. I ended up with three smaller meals a day and a snacks in between. This seemed to keep things stable, but it was a lot easier to do this, then figure out how to get 6 meals a day!
Lastly, if you can, I would recommend going to a nutritionist. I should have done it years ago to learn the right way to manage things.
Hope this helps.
