My wife has not been diagnosed with diabetes but she has a test meter and has taken a number of readings. About 2 hours after a meal she is in the range 4.6 to 5.3. Is that normal? She thinks it isn't because the fasting range is 4.0 to 6.0 and all her 'post-prandial' readings are in that range. She reckons they ought to be out of that range because she has had food. She finds getting to her GP difficult. Thanks for your help.
