Leveling Up: How to Handle Adrenaline-Induced Blood Sugar Spikes in Competitive Gaming

The Final Circle: My Personal Battle with the 'Adrenaline Spike'

I was 12-12 on Haven. The Spike was planted at C, and I was the last one alive on my team. My headset was buzzing with the frantic callouts of my teammates, but I tuned them out, focusing entirely on the sound of footsteps. My heart was hammering against my ribs like a trapped bird. My palms were slick with sweat, making it hard to grip my mouse. After a tense twenty seconds of cat-and-mouse, I flicked to the left, hit a clean headshot, and defused with 0.5 seconds to spare. The "Victory" screen flashed, my friends screamed in the Discord call, and I felt like a god.

Ten minutes later, I felt like trash.

I wasn't hungry, and I hadn't eaten anything in three hours, but I felt that familiar, heavy pressure behind my eyes. I swiped my phone over my sensor. 250 mg/dL and rising.

For many young gamers living with Type 1 Diabetes (T1D), this is the "invisible opponent." We often talk about the "pizza spike" or the "dawn phenomenon," but we rarely discuss the "competitive spike." When you're in the zone, your body doesn't know you're just sitting in a high-back ergonomic chair; it thinks you’re fighting for your actual life. That rush of excitement feels almost identical to the symptoms of high blood sugar—jitters, rapid heartbeat, and hyper-focus—which makes it incredibly easy to overlook until the match is over and your levels are through the roof.

The Science of the Boss Fight: Why Adrenaline Hits Your Glucose

To beat the spike, you have to understand the "boss mechanics" of your own endocrine system. When you enter a high-stakes competitive environment—whether it’s a ranked ladder in League of Legends or a final circle in Warzone—your body triggers the "fight or flight" response.

Your adrenal glands release epinephrine (adrenaline) and cortisol. In the wild, these hormones tell your liver, "Hey, we're being chased by a predator! Dump all the stored glucose into the bloodstream right now so we have the energy to run!"

The problem? You aren't running. You’re sitting perfectly still, clicking a mouse. Your muscles aren't burning off that sudden flood of sugar, so it just sits in your blood, driving your numbers up.

This is fundamentally different from a "pizza spike." A food spike is caused by carbohydrates being broken down in the gut; it’s external. An adrenaline spike is internal—it’s your own liver "griefing" you. Because there’s no fat or protein slowing this down, the rise can be incredibly sharp, often looking like a vertical line on your Continuous Glucose Monitor (CGM).

Pre-Game Lobby: Preparing Your Body for the Grind

You wouldn't enter a tournament with 20% battery on your wireless mouse, so why start a session with unstable blood sugar? Preparation in the "pre-game lobby" is the most effective way to mitigate the adrenaline hit.

First, aim for a stable baseline. If I see I’m already at 180 mg/dL with an upward trend, I know that queuing for a ranked match is going to send me to 300. I wait. I take a small correction or go for a five-minute walk to level out.

The Ultimate Peripheral: Water. Dehydration is the silent killer of both aim and insulin sensitivity. When you’re dehydrated, your blood is more concentrated, making your glucose readings appear higher and your insulin work slower. Keep a large gallon jug at your desk. Make it a rule: every time a round ends or you’re waiting for a respawn, take a sip.

Check the Arrows, Not Just the Numbers. Before you hit "Find Match," look at your CGM trend arrows.

• Horizontal arrow: You’re clear to queue.
• Diagonal up: Consider a tiny "preventative" bolus (with doctor approval) or wait ten minutes.
• Double arrows up: Do not queue. You’re already spiking, and the game will only make it worse.

The 'Pro-Gamer' Strategy for Temp Basals and Bolusing

If you use an insulin pump, you have a powerful tool at your disposal: the temporary basal rate or "Gaming Profile."

I sat down with my endocrinologist and explained that my blood sugar consistently jumps 80–100 points during intense sessions. We created a "Gaming Profile" that increases my basal insulin by 20-30% starting 30 minutes before I plan to play and lasting until the session ends. This provides a steady "buffer" of insulin to meet the glucose my liver is dumping.

Avoid the 'Rage Bolus' We’ve all been there. You see 260 mg/dL on your screen, you’re tilted because you just lost a match, and you aggressively pump in a massive correction dose. Don't do it.

Adrenaline-induced highs are notoriously fickle. As soon as the adrenaline leaves your system, your insulin sensitivity often skyrockets. If you "rage bolus" during the peak of the stress, you are setting yourself up for a massive, dangerous crash once you log off. Treat the spike conservatively.

Tech Specs: Using CGMs and Smart Watches to Stay Alert

In a competitive game, a split-second distraction can cost you the win. You don't want to be digging your phone out of your pocket to check your levels.

Glanceable Data If you use a Dexcom or Libre, look into "Nightscout" or apps that allow you to display your blood sugar on your computer desktop or a smart watch. I use a watch face that keeps my reading in the corner of my wrist. A quick half-second glance during a reload is all I need to stay informed without breaking immersion.

Custom Alerts Set your "High" alert a bit lower than usual when gaming—maybe at 170 mg/dL. This gives you an early warning before the adrenaline really takes hold. However, make sure the alert sound isn't the same as your in-game notifications. You don't want to mistake a "Low Battery" warning for a "Low Blood Sugar" alert in the heat of battle.

The Duo-Queue Safety Net If you have a trusted friend you play with regularly, consider giving them access to your CGM data via "Follow" apps. There have been times when I was so focused on a raid that I ignored my pump’s vibrations. Having my duo-partner say, "Hey man, your sugar is 70 and dropping, go eat a snack," has saved me from more than a few "game over" moments in real life.

Post-Match Analysis: Dealing with the Downward Slope

The match is over. Your team won, the adrenaline is fading, and you’re feeling relaxed. This is the most dangerous time for a T1D gamer.

As your body enters the "rest and digest" phase, it realizes it has a bunch of excess glucose and potentially a bunch of extra insulin (from your corrections or gaming basal) floating around. Furthermore, your liver wants to "recharge" the glucose it just dumped, so it starts pulling sugar out of your blood.

This is the Post-Tournament Crash. I’ve seen my sugar go from 240 to 60 in less than forty minutes after a particularly intense session.

1. The Cool Down: Stay at your desk for 15 minutes after you stop playing. Don't just jump into bed or go for a run.
2. The Stabilization Snack: Eat a small snack with complex carbs and protein (like peanut butter on crackers) to provide a slow release of energy as the adrenaline wears off.
3. The Logbook: Take a mental note (or a physical one) of how that specific game affected you. Did Valorant cause a bigger spike than Minecraft? (Spoilers: Yes, it did.)

Mindset and Mental Health: Don't Let the Numbers Tilt You

Perhaps the most important piece of advice I can give is this: Don't let the numbers tilt you.

In gaming, "tilt" is when emotional frustration leads to poor performance. If you see a high number and get angry at your body, you’re going to play worse, which will stress you out more, which will make your blood sugar go even higher. It’s a vicious cycle.

Accept that some spikes are inevitable. You are pushing your body and mind to their limits, and T1D is just another game mechanic you have to master. It’s like playing on "Hard Mode." When you win a match while managing your levels, you haven't just beaten the other team—you’ve beaten a chronic illness in real-time.

There is a massive community of "Diabetic Gamers" out there on Discord, Reddit, and Twitch. We are all dealing with the same "invisible opponent." Reach out, share your strategies, and remember that having T1D doesn't mean you can't be a pro. It just means you have to be more disciplined, more aware, and more strategic than everyone else on the server.

So, next time you’re in the final circle, take a deep breath. Check your levels, stay hydrated, and remember: you've got this. GG, well played.
