Short answer
What are the signs of low blood sugar?
The signs of low blood sugar are feeling shaky or jittery, hunger, tiredness, dizziness, confusion or irritability, a fast or irregular heartbeat, headache, and trouble seeing or speaking clearly (NIDDK, Low blood glucose (hypoglycemia)).
Hypoglycemia symptoms can start quickly and differ from person to person. For many people with diabetes, low means a reading below 70 mg/dL, and your targets may differ, so ask your care team.
| Stage | What it looks like | What to do |
|---|---|---|
| Mild or moderate | Shaky, hungry, dizzy, irritable, fast heartbeat | Check if you can; eat or drink 15 to 20 grams of glucose or carbohydrate |
| After 15 minutes | Still low | Recheck, and repeat if still low |
| Severe | Confusion, fainting, seizure | Glucagon if available; call 911 |
Who is at risk
Who gets low blood sugar?
People who take insulin or certain diabetes pills are most at risk, since insulin and two kinds of pills (sulfonylureas and meglitinides) can cause it (NIDDK, Low blood glucose (hypoglycemia)).
NIH adds that chromium, a trace mineral, taken with insulin might raise the risk of low blood sugar (NIH ODS, Chromium). In general, a supplement that might lower blood sugar adds to medicine that can. Olivaro lists 0.7 mcg of chromium, 2% of the Daily Value, and 21 other names in a blend. No trial tested Olivaro, and we do not claim it causes or prevents low blood sugar.

When are low blood sugar signs an emergency?
Loss of consciousness or a seizure is an emergency: give glucagon if available and call 911.
Also get care if signs keep coming back, or if you cannot treat them yourself. Tell your clinician about every supplement you take, and ask a pharmacist before adding one if you use insulin or diabetes pills. Never stop or change a prescribed medicine because of a supplement.
Keep taking prescribed medicine. Signs of severe low blood sugar (confusion, fainting, seizure), chest pain or trouble breathing: call 911.

FAQ
Olivaro questions people ask
Is sweating a sign of low blood sugar?
The NIDDK list we used does not name sweating, so we do not state it as a sign. If you feel shaky, dizzy or confused, check your reading if you can and follow your care team's plan.
What number counts as low blood sugar?
For many people with diabetes, NIDDK says a reading below 70 mg/dL is low. Your own target may differ, so ask your care team what number applies to you.
Can low blood sugar happen without diabetes?
We did not research that for this post, so we make no claim. Ask a clinician about repeated signs, whatever your diagnosis.
