Can you feel when you ‘go low’? There are lots of different symptoms when blood sugar goes too low. Hypoglycaemia is defined as a blood sugar level at or under 4mmol/l and some symptoms of this include feeling shaky, hungry, sweaty, or having tingly lips.
Some people get symptoms before reaching 4mmol/l but this is technically not a hypo. And some people don’t feel symptoms until they reach under 4mmol/l. One of the reasons this happens is your body gets used to the levels it runs at, so if you have lots of high blood sugars in the late teens or 20’s going down to 7mmol/l would be a bigger drop than someone who runs around 5-7 mmol/l dropping to 3 mmol/l. Basically the bigger drop the more likely you will have physical symptoms. But you don’t need to treat unless your blood sugar is less than 4 – “4 is the floor”
