The Concert Survival Guide: Managing Your CGM and Blood Sugar in the Front Row

The High-Stakes Stage: Why Concerts and CGMs Don't Always Mix

I’ll never forget my first big show after transitioning to a Continuous Glucose Monitor (CGM). It was an intimate, acoustic set by one of my favorite indie artists. The venue was packed, the lights were low, and the singer had just started a hauntingly beautiful ballad. The room was so quiet you could hear a pin drop—or, in my case, a high-pitched, rhythmic beep-beep-beep emanating from my pocket. My blood sugar was crashing, and suddenly, I wasn't a fan lost in the music; I was the person whose medical tech was providing an unwanted backing track to the emotional climax of the night.

That moment of sheer embarrassment taught me a vital lesson: concerts are a unique "perfect storm" for people living with diabetes. You have the physical exertion of dancing for three hours, the sweltering heat of a thousand bodies packed into a GA pit, and the massive surge of adrenaline that comes when the headliner finally hits the stage. For a CGM, this is the ultimate stress test.

Managing your levels in the front row is high-stakes. If you go too low, you’re fighting through a dense crowd to find a $9 orange juice. If you go too high, the dehydration and fatigue can ruin your stamina before the encore. Our goal today isn't just "surviving" the show; it’s about mastering your tech and your body so you can scream-sing every lyric without a single glance at your receiver.

The Pre-Game Ritual: Calibrating for the Chaos

Success at a concert starts long before you scan your ticket. I like to think of the two hours before doors open as my "calibration window." This is the time to ensure my CGM is reading accurately and my body is fueled for the marathon ahead.

First, I always perform a finger-stick check about two hours out. While modern CGMs are incredibly accurate, I want to ensure my sensor isn't drifting before I enter an environment where I can't easily sit down and calibrate. If my CGM says 110 and my meter says 140, I want to know that now, not when I’m trying to figure out why I feel shaky in the middle of a mosh pit.

Next comes the "Pre-Concert Meal." The temptation to grab a quick slice of greasy pizza outside the venue is real, but that’s a recipe for a "pizza spike" three hours later. My go-to strategy is a balance of complex carbs and high protein. Think a grilled chicken wrap with whole-grain tortilla or a quinoa bowl with plenty of fiber. The protein and fiber act as a "brake" for the carbohydrates, providing a slow, steady release of energy that can withstand the excitement of the opening act.

Finally, I utilize the "Activity Mode" or "Temp Target" feature on my insulin pump or CGM app. I usually set this about an hour before the music starts. By raising my target blood sugar slightly (for example, aiming for 140-150 mg/dL instead of 110), I create a "buffer zone." This prevents my pump from giving me too much basal insulin while I’m jumping around, significantly reducing the risk of a mid-show plummet.

Security and Sensors: Getting Through the Gate Without a Meltdown

The security line is often the most stressful part of the night. You’re worried about your sensor seting off the metal detector, or worse, a security guard questioning your insulin pens or glucose gels.

The golden rule? Communication is key. As I approach the front of the line, I usually have my pump or CGM receiver in my hand. I simply say, "I have a medical device attached to my body and I'm carrying life-saving medical supplies." Most security personnel at major venues are well-trained on this, but if you encounter someone who seems confused, don't be afraid to ask for a supervisor.

One of my favorite "hacks" is the Medical Bag Strategy. Most venues now have strict clear-bag policies. I use a dedicated clear pouch specifically for my diabetes supplies. Not only does this make the security search faster, but it also ensures that if I need to hand my bag to a friend while I tie my shoe, they know exactly which bag contains the "life-saving stuff."

Regarding the tech itself: most CGM manufacturers state that sensors are safe for walk-through metal detectors but should avoid full-body scanners (the ones where you hold your hands up). I always opt for a hand-pat-down if a full-body scanner is the only option. It feels a bit extra, but it's better than a fried transmitter halfway through the tour.

The Adrenaline Factor: Why My Sugar Spiked Before the First Note

You’ve made it through security, you’ve found your spot at the barricade, and the lights go down. Suddenly, your CGM starts trending upward. You haven't eaten anything in three hours—so what gives?

Welcome to the Science of Hype. When you’re excited, your body releases adrenaline and cortisol. These hormones tell your liver to dump stored glucose into your bloodstream to give you the energy to "fight or flight" (or in this case, dance and scream). To your CGM, this looks exactly like you just ate a hidden candy bar.

The biggest mistake I see (and have made myself) is the "Rage Bolus." You see a 210 mg/dL with a "double up" arrow and you panic, slamming a massive dose of insulin to bring it down. But remember: that adrenaline spike is temporary. Once the initial excitement levels off and the physical exertion of dancing kicks in, that extra insulin will hit you like a freight train.

Instead of bolusing aggressively, I focus on hydration. Drinking water helps your kidneys flush out excess glucose and keeps you from feeling the "sluggishness" of a high. If I do bolus, I usually only give half of what my pump suggests, knowing the dancing will do the rest of the work.

The 'Mosh Pit' Shield: Protecting Your Gear from the Crowd

If you’re a "front row or bust" kind of person, you know that the pit is a contact sport. People are bumping, sweating, and surging. This is a nightmare for medical adhesives.

I’ve learned the hard way that arm placements are risky for General Admission. One enthusiastic fan swinging their arms can easily snag a sensor right off your tricep. For concert season, I prefer "stealth placements"—the upper thigh or the lower abdomen. These areas are much more protected by your clothing and less likely to be bumped by strangers.

To combat the "sweat factor," I swear by liquid adhesives (like Skin-Tac) and high-quality overpatches. I want that sensor to be essentially laminated to my body. I also think about my outfit choice. High-waisted jeans or compression shorts are great for keeping a pump secure against your body, preventing it from swinging around and pulling on the infusion site while you move.

The Emergency Kit: Snacks and Supplies That Fit in a Fanny Pack

When you’re packed into a crowd, you don't want to be lugging a heavy backpack. The fanny pack (or "crossbody bag") is the ultimate concert companion. But you have to be strategic about what goes inside.

My "Non-Crushable" snack list is vital. Granola bars turn into dust in a crowded pit. Instead, I opt for:

• Glucose Tabs: They are indestructible and fast-acting.
• Fruit Leathers: Flat, easy to pack, and they don't melt in the heat.
• Honey Packets: Small and provide an almost instant rise.

I also always carry a backup finger-stick kit. Extreme heat and heavy perspiration can occasionally cause CGMs to give "Sensor Error" readings. If my tech fails, I need to know my number the old-fashioned way. Lastly, never underestimate the power of a medical ID bracelet. In a dark, loud room, if you were to have a severe low and lose consciousness, that bracelet tells the paramedics exactly how to help you.

Handling the Alerts: What to Do When the CGM Starts Screaming

Back to my story about the quiet ballad: how do we avoid the "Beep of Shame"? Most modern CGM apps allow you to customize your alerts. Before I enter the venue, I switch my alerts to "Vibrate Only" for everything except "Urgent Low." This keeps my medical data private while still ensuring I’m safe.

I also utilize the "Buddy System." I make sure my concert buddy knows what my alerts sound like. I tell them, "If you feel my pocket vibrating or hear a specific siren, it means I need to step back and eat a snack." Having someone else aware of the situation takes a massive weight off my shoulders.

And here is the hardest piece of advice to follow: Know when to step out. If you’re at 55 mg/dL and falling, it doesn't matter if your favorite song just started. Your safety is the priority. Missing four minutes of a show to treat a low is much better than spending the rest of the night in the medical tent.

The After-Party: Managing the Post-Concert Crash

The show is over, your ears are ringing, and you’re riding a high. But for your blood sugar, the real work is just beginning. This is the "Delayed Drop." All that dancing has depleted your muscle glycogen, and for the next 3 to 12 hours, your body will be working overtime to pull glucose out of your blood to refit those stores.

I never go straight to sleep after a concert without a "Safety Snack." I look for something with slow-burning carbs and fat—like peanut butter on toast or a handful of nuts and a piece of fruit. This provides a steady stream of glucose to counter the post-exercise dip that usually happens around 3:00 AM.

Managing a CGM at a concert takes a bit of extra planning, but it’s the difference between being a spectator of your own life and being a participant in the moment. When you master the prep, the security, and the adrenaline, you realize that diabetes doesn't have a VIP pass—it’s just another member of the crew.

Now, go buy those tickets, prep your fanny pack, and get ready to lose your voice in the front row. You’ve got this!
