If you live with diabetes, you probably know the feeling. You're suddenly shaky, a little sweaty, maybe foggy or hungry out of nowhere. That's often your body telling you your blood sugar is dropping.
The good news? There's a simple plan for handling it that's easy to remember, even when you don't feel your best. It's called the 15-15 rule, and it's the approach recommended by the American Diabetes Association.
Let's walk through it together. No medical degree required.
First, what counts as "low"?
For most people, low blood sugar (also called hypoglycemia) means a reading below 70 mg/dL. Your own number might be a little different, so ask your doctor or care team what "time to act" looks like for you.
Common signs of a low include:
- Feeling shaky, nervous, or anxious
- Sweating or feeling clammy
- A fast heartbeat
- Feeling dizzy or lightheaded
- Sudden hunger
- Feeling cranky or confused
Everyone's different, and symptoms can change over time. Getting to know your own early signs is one of the best things you can do.
The 15-15 rule in three easy steps
1. Have 15 grams of fast-acting carbs.
Fast carbs get into your system quickly. Think glucose tablets, glucose gel, or a half cup of juice or regular (not diet) soda.
2. Wait 15 minutes.
Sit down, take a breath, and give it time to work. It's tempting to keep eating until you feel better, but waiting helps you avoid swinging too high.
3. Check again.
If you're still below 70 mg/dL, or your CGM isn't showing your numbers heading up, have another 15 grams and repeat.
Once you're back in range, and your next meal isn't coming soon, have a small snack with carbs and protein, like cheese and crackers. It helps keep you steady until your next meal.
What does 15 grams of fast carbs look like?
According to the American Diabetes Association, these all work:
- Glucose tablets (check the label for how many make 15 grams)
- One tube of glucose gel
- ½ cup (4 ounces) of juice or regular soda
- 1 tablespoon of sugar or honey
Try to skip chocolate, cookies, and other foods with a lot of fat when you're treating a low. Fat slows things down, and right now you want quick.
Here's the tricky part: when you're shaky and foggy, measuring and counting is the last thing you want to do. That's why so many people like having a pre-measured option ready to go.
Where Elovate fits in
We've been making fast-acting glucose since 2013, and we keep it simple.
Elovate 15 Slimpaks give you 15 grams of glucose in every packet. That's one full 15-15 serving, with no math. The powder dissolves right on your tongue, so there's no water needed. Each slim, waterproof packet is individually sealed and slips easily into a pocket or bag. They come in flavors like Black Cherry, Strawberry, and Watermelon, and they're FSA/HSA eligible.
Elovate Glucose Tablets are a great pick if you like something to chew. Each tablet has 4 grams of glucose, and the label serving is 4 tablets (15 grams of carbs). They come in handy tubes of 10, in fruity flavors like Blueberry, Grape, Peach, and Raspberry. They're gluten-free, fat-free, caffeine-free, and made with no artificial dyes. Want to try them first? There's also a smaller 2-tube pack.
A friendly tip: keep a stash everywhere you spend time. Your bag, your desk drawer, your nightstand, your gym bag. A low is much less stressful when help is always within reach.
On the move? Plan ahead
Exercise can lower blood sugar, sometimes hours after you finish. If you walk, run, hike, or play sports, bring fast carbs along every time. A Slimpak tucks into a pocket or running belt, and because it's waterproof, a little sweat or rain won't bother it.
When to get help right away
The 15-15 rule is for when you're awake, alert, and able to swallow. If someone is too confused to eat or drink safely, or passes out, don't put food or drink in their mouth. Use glucagon if it's been prescribed, and call 911. And if your numbers aren't coming up after a couple of rounds, get medical help.
It's a good idea to talk with your care team about whether you should carry glucagon, and to show family and friends how to help.
The bottom line
15 grams. 15 minutes. Check again. That's it. Keep your fast carbs close, know your signs, and you'll be ready when a low shows up.
