Does Low Blood Sugar Scare You? Here’s What You Can Do About It - The Diabetes Link

Written by Mark Heyman | Aug 4, 2025, 4:00:00 AM

Low blood sugar can be anxiety-provoking, but fear of lows doesn’t have to take over your diabetes management or your life.

Maybe you’ve had a scary low in the past. Or maybe you’ve just heard stories about the dangers of low blood sugar and want to avoid ever finding yourself in that position.

So you start by nudging your blood sugars up a little. Then you begin taking a few units off your dinner bolus when it feels like “too much.”

After a while, you’re stuck in a pattern where fear, not facts, is calling the shots. And no matter how badly you want to conquer that fear so you can manage your diabetes and live with confidence, you just can’t seem to break free.

Jaden is a college student who’s been living with type 1 diabetes for 7 years. She’s smart, independent, and used to be up for anything—late-night study sessions, weekend road trips, even a semester abroad.

But a couple years ago, she had a seizure in the middle of the night from a severe low blood sugar that shook her confidence.

Since then, Jaden’s done everything she can to avoid going low again. She runs her blood sugars higher than she’d like, just to feel safe. She turns down last-minute plans with friends. She skips out on class sometimes if she’s worried about crashing.

What started as a way to protect herself now keeps her feeling stuck. She wants to live her college years fully—but her fear of going low is calling the shots.

Having anxiety about low blood sugar is normal, and sometimes it’s even helpful. But what matters most is how we respond to that fear.

Fear of Hypoglycemia: What It Really Does

Fear of low blood sugar is one of the most common mental health challenges for people with diabetes. Research shows that up to 1 in 3 people with type 1 diabetes and 1 in 6 people with type 2 diabetes experience a significant fear of hypoglycemia. But many don’t even realize this is what’s happening.

Why? Because it often hides behind what looks like reasonable behavior:

  • Underbolusing “just in case”
  • Setting CGM alerts higher than needed
  • Avoiding exercise or alcohol
  • Eating extra at bedtime
  • Skipping or modifying plans where lows could be inconvenient or embarrassing

These choices may feel like they are keeping you safe. But over time, they can lead to consistently high blood sugars, growing frustration, and a loss of confidence. What starts as a coping strategy becomes a trap.

You’re Not Broken. Your Brain Is Doing Its Job.

Your brain is wired to avoid discomfort, especially when that discomfort feels life-threatening. So when your brain says, “Let’s not go there again,” it isn’t being irrational. It’s trying to protect you.

The problem is that your brain often can’t tell the difference between actual danger and perceived danger. A 70 mg/dL with a juice box in reach can feel just as scary as a 40 mg/dL in the middle of the night.

These situations might feel the same, but they aren’t equally dangerous.

So if you’re keeping your blood sugar high to feel safe, your brain has won the short-term game. But the cost is your long-term health and freedom.

You Don’t Have to Eliminate Fear. You Just Have to Learn to Handle It.

Here’s where most people get stuck: they think they need to wait until they feel comfortable to make a change. They wait for the fear to go away before they take action.

Kristen struggled with this. She was diagnosed as a teen and went through a traumatic DKA experience after a long honeymoon period. Since then, she’s been hesitant to take her full bolus, even when she knows it’s what her body needs.

What helped Kristen turn the corner wasn’t “getting over” her fear. It was learning how to act even while she still felt anxious.

That’s what real freedom looks like.

Try This: A Simple Shift to Help You Reclaim Control

Here’s a technique you can use to start managing your fear of lows more effectively.

Step 1: Name the Fear

Instead of telling yourself that you’re “just being cautious,” say what’s really going on. For example: “I’m afraid of going low at lunch because I have a meeting after.”

Step 2: Separate Thoughts from Actions

Feeling anxious doesn’t mean you have to underbolus. Ask yourself, “What would I do if I wasn’t afraid?” Then consider doing that, even if the fear is still there. Remind yourself that you are prepared and safe.

Step 3: Start Small (but start)

If doing things like taking your full bolus feels overwhelming, start by pushing yourself just a bit more than you normally would. For example, if you need 7 units of insulin for a 50g meal and you’d usually take 4 units, try taking 5. Small steps are progress—as long as you keep moving forward.

Step 4: Make a Plan for the Fear

Don’t just hope you won’t go low. Plan for it. Have your low snacks with you. Keep ready-to-use glucagon on hand. Make sure your CGM alerts are set to help you catch a low early. That way, you’re not ignoring the risk, you’re managing it.

You’re Capable of More Than You Think

If you are afraid of lows, that doesn’t mean you’re weak. It means you’re human. But fear doesn’t have to be in charge.

You don’t have to eliminate fear to live a full life with diabetes. You just need the right tools, support, and willingness to take action, even when it’s uncomfortable.

“You don’t have to eliminate fear to live a full life with diabetes. You just need the right tools, support, and willingness to take action, even when it’s uncomfortable.”

People like Jaden and Kristen are learning this. Their worlds are getting bigger again.

And if you’re ready to take that first uncomfortable step, yours can too.
