Recognizing early signs of low blood sugar

A low blood sugar when you’re alone in public can sneak up fast and acting quickly is crucial. 

• Watch for shaky hands, sweating, sudden hunger, dizziness or brain fog.
  • These are early warning signs—act fast to stay safe.
• Not sure if it’s a low? Treat first, check later.

Your body is sounding the alarm. Catch it early to stay upright, stay safe and skip the scary stuff.

Quick moves during a public low

If you feel symptoms of hypoglycemia, do the following:

• Sit down somewhere safe: Keeps you steady and protects from falls.

• Feeling weak or unsure? Ask someone nearby for help.

• Have Medical ID? Point to it or show your diabetes card to speak for you.

• Language gap? Use gestures or show a phone message to explain.

Fast-acting carbs = your secret weapon during a public low

Keeping fast-acting carbs nearby is your best defense against low blood sugar when you’re alone in public.

• Pack smart: Glucose tabs, juice boxes, jellybeans, or Smarties—all pocket-friendly.
• No snacks? Grab 15–20g of sugar from a nearby café: juice, soda (not diet), or gummy candy.
• Build a grab-and-go kit: With shelf-stable carbs so you’re always ready.

Hypothetical: “What if I forgot my snacks?” 

Solution: Check cafés, stores or vending machines for juice, soda or candy. Say it’s for a medical emergency if needed.

Stay calm and take control during a low

• Breathe: Inhale for 4 counts, hold and exhale slowly.
  • It helps you focus while sugar starts working.
• Treat: With fast-acting carbs, then wait 15 minutes.
• Still low? Repeat the treatment.

Hypothetical: “How long should I wait before I start walking again?” 

Solution: Wait at least 15–20 minutes and, if known, when your glucose is back to a safe range. Don’t stand until you feel steady. 

What people with diabetes carry and tell themselves during a low

When a low hits in public, preparation is key. Everyone has their own rituals, but the common thread is preparation, self-compassion and trusting your plan. 

Here’s what people living with diabetes rely on to stay safe and steady when alone:

• “I always carry sweets (usually Skittles or Swedish Fish) and glucagon. I always tell myself ‘You know what to do! You’re prepared and you’ll be alright!’” — Mariana Gomez
• “I focus on caring about literally no one around me but myself in those moments. (i.e. who cares if I rip open this juice in Target and chug it before I’ve paid for it—judge me)” — Taylor Rindfleisch
• “As someone living with type 2 diabetes, I carry sweets and have a mini soda on me most times. There’s a stockpile of sweets in my vehicles—that’s a popular place for me to go low.” — Fil Guipoco
• “Multiple fruit snack pouches and a juice box. Juice box hits faster so I feel safer if I have that. I also keep cash on hand in case a card reader’s down—it happened to me once when I had nothing to treat with.” — Lottie Frick
• “I always carry a pack of gummies or a GoGo Squeeze—whatever fits in my purse. When a low comes on, I remind myself the sugar will kick in soon. I sit, breathe and try to distract myself while I wait.” — Willa Besner

Why glucagon should always be in your kit

• Glucagon stops severe lows, even if you pass out.
  • It works fast to raise blood sugar, usually in minutes.
• Glucagon comes as injections or inhalers, both pocket-sized.
• Instructions are easy-to-follow and some brands offer demo video.
• Train friends, family and coworkers.
  • Anyone can step in when it counts.

Hypothetical: “What if I pass out and someone finds me?” 

Solution: Glucagon + medical ID = fast help, even from a stranger. Clear kit instructions make it easy.

Need help when you are alone in public during a low?

• Say, “I have diabetes and need sugar” or “I’m having a low.”
  • If speaking is tough, point to your medical ID or show your emergency card.
• Remember, most people want to help. They just need a cue.

Use your phone as a safety tool

Your phone’s your safety sidekick for handling lows in public. 

• Add emergency contacts for quick reach.
• Use health apps for alerts, tracking and logging.
• Turn on location sharing so loved ones can find you fast.
• Some apps even share key medical info with responders.

Hypothetical: “What if my phone is dead?” 

Solution: If your phone dies, backups matter. Wear a medical ID, carry quick-sugar snacks and an info card. Even without tech, you’re not alone.
