Blood Sugar of 60 mg/dL: What It Means and What to Do
60 mg/dL (3.3 mmol/L) is a low. The ADA calls anything below 70 mg/dL (3.9 mmol/L) hypoglycemia. The usual first step from the NIDDK is 15 to 20 grams of fast-acting carbohydrate, then a recheck in 15 minutes. Follow the plan your own care team gave you.
Where 60 falls
The ADA splits lows into three levels. Level 1 is a glucose under 70 mg/dL and at least 54 (under 3.9 and at least 3.0 mmol/L). Level 2 is under 54 mg/dL (3.0 mmol/L). Level 3 is a severe event with altered mental or physical status that needs another person’s help, whatever the number. A reading of 60 is level 1. It is not an emergency by itself, but it is a reason to act now, because glucose can keep falling.
What the official sources say to do
- Treat. The NIDDK says to eat or drink 15 to 20 grams of glucose or carbohydrate right away. Its examples are four glucose tablets, a tube of glucose gel, half a cup (4 ounces) of fruit juice that is not low-calorie, or half a can of regular soda. The ADA says glucose is the preferred treatment, and to avoid high-fat or high-protein foods first because they act more slowly.
- Wait 15 minutes and check again. If it is still low, repeat. This is the rule of 15.
- Ask what to eat next. Your care team can tell you whether a snack or meal should follow, so glucose does not drop again.
- Tell your care team about lows, especially repeated ones. They may change your plan.
People who use an automated insulin delivery system may be told to use less. The ADA says typically 5 to 10 grams, so follow your system’s guidance.
Signs that go with a low
The CDC lists a fast heartbeat, shaking, sweating, nervousness, irritability or confusion, dizziness and hunger. The low blood sugar symptoms page has the full list. Some people feel nothing, so a meter or CGM reading matters.
Why a low can happen
Your care team can explain which of your medicines can cause lows. Skipped or late meals, extra activity and alcohol are common things to mention. Tell them what was different that day. The ADA recommends glucagon for anyone taking insulin or at high risk; read what glucagon is and ask whether you should have it at home.
Keep fast-acting carbohydrate within reach. Glucose tablets are easy to carry and have a known amount of carbohydrate on the label. Check the numbers against the blood sugar chart.
Frequently asked questions
Is a blood sugar of 60 dangerous?
It is low. The ADA calls anything under 70 mg/dL (3.9 mmol/L) hypoglycemia, and 60 sits in level 1 (54 to 69). It needs treating promptly, and it can get worse if untreated. Level 3, the severe kind, is defined by needing another person’s help rather than by a number.
What should I do at 60 mg/dL?
Follow the plan your care team gave you. The NIDDK’s general advice is to eat or drink 15 to 20 grams of glucose or carbohydrate right away, wait 15 minutes, and check again. See the rule of 15.
What is 60 mg/dL in mmol/L?
3.3 mmol/L (60 ÷ 18).
Can I have a reading of 60 without symptoms?
Yes. Some people do not feel a low, which the ADA calls hypoglycemia unawareness. Tell your care team if you have lows without warning signs.
Should I worry if I do not have diabetes?
A reading this low in someone not treated for diabetes is worth a conversation with a clinician, especially if it comes with symptoms. This page is not a diagnosis.
