My BS was 6.1 pre evening meal 2hrs after meal it's 4.4 should it be higher or is this ok. Bit confusing.m
It's potentially concerning, but only if it continues to drop. How long have you been taking the Metformin? Since you asked about this I assume you haven't seen this happen before?
If this is the first time you've seen this happen, then I suggest you make a note of it and also keep a closer eye on your BG (Blood Glucose) results near term. It's probably also something to mention when you next talk to your med support person.
If Metformin is the only medication you are taking, then there is a low risk of low blood sugar (hypoglycemia). However, I am not sure there is
zero/no risk. Checking your BG more frequently, especially when you have
not eaten (carbs) for a while, to verify that you are not going hypo seems like a reasonable precaution, no?
