Low Blood Sugar Signs: Hypoglycemia Symptoms and When to Get Help
Low blood sugar signs include shaking, sweating, hunger, a fast heartbeat and irritability. Blood sugar below 70 mg/dL is low, and below 54 mg/dL is severe. Confusion, fainting or a seizure needs 911. Several names on the Glyco Harmony label may add to diabetes medicine, so ask your doctor first.
Written by the Glyco Harmony label deskUpdated
The signs01
What are the signs of low blood sugar?
The common signs of low blood sugar are a fast heartbeat, shaking, sweating, anxiety, irritability, dizziness and hunger (CDC, Low Blood Sugar (Hypoglycemia)). They can come on fast.
As blood sugar falls further, weakness, trouble seeing or walking, confusion and slurred speech can follow. The most serious signs are fainting and seizures, and rarely coma (Mayo Clinic, Hypoglycemia).
Signs vary from person to person and from one episode to the next. A sign that was mild last time can be stronger today, so do not wait to see how far it goes.
Some people have no warning signs at all. The risk is higher with diabetes for 5 to 10 years, frequent lows, or beta blockers (CDC, Low Blood Sugar (Hypoglycemia)). If you are in that group, ask your care team about a plan for lows.
The numbers02
What blood sugar level counts as low?
A reading below 70 mg/dL is low and needs action. Below 54 mg/dL is severe (CDC, Low Blood Sugar (Hypoglycemia)). Individual targets vary, so use the ones your care team gave you.
A fasting level of 70 mg/dL (3.9 mmol/L) or lower is generally a warning sign (Mayo Clinic, Hypoglycemia). A continuous glucose monitor can alert you to lows during sleep, and may mean fewer low-glucose emergencies (NIDDK, Continuous Glucose Monitoring).
| Level | Typical signs | What it means |
|---|---|---|
| Below 70 mg/dL | Shaking, sweating, hunger, fast heartbeat, irritability | Low; needs action per your plan |
| Below 54 mg/dL | Confusion, weakness, trouble seeing or walking, slurred speech | Severe; often needs another person's help |
| Any level, with fainting or a seizure | Loss of consciousness, convulsions | Emergency: call 911 |
Get help03
When should low blood sugar signs go to emergency care?
Call 911 for confusion that will not clear, fainting, a seizure, or trouble breathing. Someone with diabetes who has severe symptoms or loses consciousness needs emergency care (Mayo Clinic, Hypoglycemia).
Severe lows often need another person's help (CDC, Low Blood Sugar (Hypoglycemia)). Tell the people near you what your signs look like and what your plan is. A person who is confused may not be able to ask for help.
- Shaky, sweaty, hungry, fast heartbeatThese can be low blood sugar (under 70 mg/dL is low). If you have diabetes, follow your own plan.
- Confusion, slurred speech, faintingSevere low blood sugar. Someone with diabetes who has severe symptoms or loses consciousness needs emergency care.
- Yellow skin or eyes, dark urinePossible liver trouble. Stop the drops and call your doctor. Liver injury has been reported with green tea extract and gymnema.
- Irregular heartbeat or very high blood pressureLicorice compounds such as glycyrrhizin can cause these. Get medical care.
- Call 911 nowA seizure, loss of consciousness, trouble breathing, or swelling of the face or lips needs emergency care. Do not wait for a supplement.
Signs from (CDC, Low Blood Sugar (Hypoglycemia)) (Mayo Clinic, Hypoglycemia) (LiverTox, Green Tea) (NCCIH, Licorice Root). This list is not complete, and a supplement is never a reason to wait.
Why it happens04
What causes low blood sugar?
In people with diabetes, the most common cause is medicine: too much insulin or other diabetes medication, eating less than usual after a dose, or unplanned exercise (Mayo Clinic, Hypoglycemia).
Low blood sugar is not only a diabetes problem, yet medicine is the cause the sources name first. That is why a new supplement is worth a pharmacist's look. Chromium, L-arginine, Panax ginseng and gymnema each have a source saying they may add to the effect of diabetes medicine, so low blood sugar is possible (NIH ODS, Chromium fact sheet)(Mayo Clinic, L-arginine)(NCCIH, Asian Ginseng)(LiverTox, Gymnema).

Can Glyco Harmony drops cause low blood sugar?
No study tested Glyco Harmony, so no one can say. The label names chromium and a 22-name blend, and four of those names have a source about possible effects on blood sugar medicine.
The label gives chromium at 0.7 mcg per 1 mL, which is under 1% of a common chromium-only dose (NIH ODS, Chromium fact sheet). The other names have no single amounts. Because the amounts are hidden, the label cannot rule an effect in or out.
On insulin or pills?
Ask your doctor or pharmacist before you start. Never change a dose because of a supplement.
Not on medicine?
A fast heartbeat, shaking or sweating after a new product is worth a call to your provider.
Label caution
Pregnant or nursing mothers, children under 18 and anyone with a known medical condition should consult a physician.
The directions on the label are short: shake well, then 1 or 2 droppers full daily. They do not mention food, time of day or blood sugar checks. If you use a meter or monitor, keep using it the way your care team told you. More on the interactions is in supplements and diabetes medicines and side effects.
After a low06
What should you do after a low blood sugar episode?
Tell your doctor, even if you felt fine afterward. A low is a signal that your doses, meals, activity or supplements may need review.
- Note the time, your reading if you have one, and what you ate and took that day.
- List every supplement, including drops, and share it with your pharmacist.
- Stop any new product you started recently and call your provider.
Confusion, fainting or a seizure needs 911. The FDA has not evaluated the statements on the Glyco Harmony label, and it is not a diabetes medicine.
FAQ07
Low blood sugar questions
Can you have low blood sugar without diabetes?
Yes. A fasting level of 70 mg/dL or lower is generally a warning sign, though targets vary. Causes in people without diabetes differ, so see a doctor if you have repeated episodes.
What does low blood sugar feel like?
Many people feel shaky, sweaty, hungry or anxious, with a fast heartbeat and dizziness. Irritability and confusion can follow. Some people feel nothing, so a monitor and a plan from your care team help.
What is the difference between mild and severe hypoglycemia?
Below 70 mg/dL is low, and below 54 mg/dL is severe. Severe lows bring confusion, weakness, trouble seeing or walking, and sometimes seizures. They often need another person's help.
Can low blood sugar happen while you sleep?
Yes. A continuous glucose monitor can alert you to lows during sleep. Ask your care team whether one fits you, and tell them if you often wake feeling unwell.
Can a supplement mask low blood sugar signs?
Beta blockers can leave people without warning signs. Guarana, a name on this label, is a caffeine source that can change the heartbeat at high amounts. Check readings rather than guessing from how you feel.
When is low blood sugar an emergency?
When there is confusion that will not clear, fainting, a seizure or loss of consciousness. Call 911. Someone with diabetes and severe symptoms needs emergency care, and a bystander may need to call for them.
