Question: what are "normal" blood glucose levels?

 Kazzy - Wed Nov 24, 2004 6:06 am


I ran a few random blood glucose tests on myself as i wanted to rule out hypoglycemia as the cause of my migraines.

The results i got ranged from 3.9mmol/L to 7.7mmol/L

I'm not sure if this is normal or not however as i've found alot of varying levels when i ran a search on the internet.

Could you please let me know if these levels are within the normal range or not.

Thank you,

User avatar Hello Karen,
Hypoglycemia does not have an established biochemical criterion. The diagnosis of hypoglycemia requires careful correlation with clinical features. However, generally speaking a random glucose level of <2.2 mmol/L in an adult female should raise concerns of hypoglycemia.

from what i know of diabetes (my brother has had type one for 10 years)

for a person that does not have diabetes, 7.5 or below is normal.
peaking slightly above that can occur and optimal level is 3.5-5

sustained higher levels can produce symtpoms such as excessive urination, rapid weight loss, excessive thirst etc

if you have continued migraines or you measure you blood glucose and it is regularly above 7.5; see your doctor.
