I just wanted to pipe up to say that impaired glucose tolerance can show up as low BG. As well as high.
This can be reactive hypoglycaemia, or a lot more subtle.
- there is often a phase, long before it develops into prediabetes, or diabetes, where low BG several hours after eating is the only sign there is impaired glucose tolerance.
Learned that from my new and latest favourite D book, the Diabetes Miracle by Diane Kress.
(She uses this early sign to diagnose potential problems, and prevent a worsening of the problem by using diet)
