Most people with a blood sugar level under 40 mg/dL will have symptoms. These include:
- Episodes of feeling warm, sweaty and "out of touch"
- Unexplained episodes of heavy sweating
- Extreme hunger at unexpected times
- Feeling shaky and lightheaded
- Difficulty concentrating
Maybe you mentioned these symptoms to your doctor and that is why you had this blood test.
Why was the blood glucose test performed?
It was part of a routine blood panel.
My doctor was concerned about my symptoms.
I am not sure why the blood sugar test was done.
