Know Before the Low™

For people with diabetes, balancing the highs and lows of blood sugar is part of everyday life. Even with careful monitoring, low blood sugar can happen unexpectedly. That’s why it’s important to Know Before the Low.

What is low blood sugar (hypoglycemia)?

Low blood sugar is when your blood sugar levels have fallen low enough that you need to take action to bring them back within a target range. This usually occurs when blood sugar levels are less than 70 mg/dL. It’s important to be prepared and talk to your diabetes care team about your own blood sugar targets and what is too low for you.

Low Blood Sugar Signs and Symptoms

It’s also possible to experience no symptoms at all, and still have low blood sugar. This is called hypoglycemia unawareness.

The only sure way to know whether you’re experiencing a low is to check your blood sugar, if possible. If you’re experiencing symptoms and are unable to check your blood sugar for any reason, treat the low blood sugar.

Managing Low Blood Sugar

Managing low blood sugar depends on the severity of the low. Mild or moderate lows can be treated with fast-acting carbohydrates such as juice, candy, or glucose tablets, while severe low blood sugar emergencies require a prescription rescue medication, such as glucagon. Here’s a helpful breakdown of the different levels of low blood sugar—and how to treat them.
