Managing Type 1 Diabetes for Athletes: Essential Strategies and Tips
Managing type 1 diabetes as an athlete requires a multi-faceted approach that goes far beyond what non-athletic individuals experience. The combination of physical exertion, competitive stress, and varying activity levels creates unique challenges that demand careful planning and constant vigilance.
Daily Blood Sugar Monitoring and Insulin Adjustments
Athletes with type 1 diabetes must monitor their blood glucose levels far more frequently than sedentary individuals. NFL tight end Mark Andrews, who plays for the Baltimore Ravens, checks his blood sugar approximately 30 times during a single game to maintain optimal control. This level of monitoring isn’t excessive but necessary to prevent both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) during intense physical activity.
The insulin-exercise relationship is complex. Exercise increases insulin sensitivity, meaning the body requires less insulin to process glucose. Athletes must adjust their basal insulin rates before, during, and after training sessions. According to clinical research published in the NIH database, insulin requirements can decrease by 20-50% during prolonged physical activity.
Expert Insight
High school basketball players Braylon Ellis and Andrew Tatum, both managed by the University of Kentucky’s Barnstable Brown Diabetes Center, have developed precise routines for managing their condition during games. They monitor glucose levels before games, at halftime, and immediately after, making real-time adjustments to their insulin delivery and carbohydrate intake based on the data.
Carbohydrate Counting and Timing
Strategic carbohydrate intake is essential for maintaining stable blood sugar during athletic performance. Athletes must consider:
- Pre-exercise nutrition: Consuming 15-30 grams of complex carbohydrates 1-2 hours before activity
- During exercise: Quick-acting carbohydrates available for immediate treatment of hypoglycemia
- Post-exercise recovery: Replenishing glycogen stores with a combination of carbohydrates and protein
- Hydration strategies: Balancing fluid intake with blood sugar management
The type of sport also matters. Endurance athletes require different carbohydrate strategies than those in high-intensity interval sports like basketball or soccer.
The Role of Technology in Supporting Athletes with Tye 1 Diabetes
The technological revolution in diabetes management has been transformative for athletes. Modern devices provide real-time data and automated insulin delivery that was impossible just a decade ago.
Continuous Glucose Monitors (CGMs)
CGMs have become game-changers for athletes with type 1 diabetes. These small sensors, inserted under the skin, measure glucose levels every few minutes and transmit data wirelessly to a smartphone or receiver. The benefits for athletes include:
- Real-time glucose readings without finger-stick blood tests
- Trend arrows showing whether glucose is rising, falling, or stable
- Customizable alarms for high and low glucose levels
- Data sharing capabilities allowing coaches and parents to monitor remotely
Dave Peterson, a baseball executive who manages type 1 diabetes, credits his CGM with maintaining an A1c level in the healthy range while managing the demands of professional sports. The continuous data allows him to make proactive adjustments rather than reactive corrections.
| Technology | Primary Benefit for Athletes | Usage Considerations |
|---|---|---|
| Usage Considerations | Real-time glucose tracking without finger sticks | Requires sensor replacement every 7-14 days; may require calibration |
| Insulin Pump | Precise insulin delivery; adjustable basal rates | Must be removed or protected during contact sports |
| Hybrid Closed-Loop System | Automated insulin adjustments based on CGM data | Still requires carb counting; may need manual overrides during intense exercise |
| Smart Insulin Pens | Dose tracking and calculation assistance | Less automation than pumps; requires multiple daily injections |
Insulin Pumps and Hybrid Closed-Loop Systems
Insulin pumps deliver rapid-acting insulin continuously through a small catheter inserted under the skin. For athletes, the advantages include:
- Ability to adjust basal insulin rates for different activity levels
- Precise bolus dosing for meals and corrections
- Temporary basal rate reductions during exercise
- Integration with CGMs for automated insulin delivery
Hybrid closed-loop systems, sometimes called “artificial pancreas” technology, combine CGM data with insulin pump delivery to automatically adjust insulin based on glucose trends. While these systems still require user input for meals and exercise, they significantly reduce the mental burden of constant decision-making.
Important Consideration
Contact sports may require temporarily disconnecting insulin pumps or using protective cases. Athletes should work with their endocrinology team to develop sport-specific management protocols.
Inspiring Success Stories of Athletes Thriving with Type 1 Diabetes
Real-world success stories demonstrate that type 1 diabetes is not a barrier to athletic achievement. These athletes serve as inspiration and proof that proper management enables elite performance.
Mark Andrews - NFL Tight End
Baltimore Ravens tight end Mark Andrews was diagnosed with type 1 diabetes at age nine. Rather than limiting his athletic ambitions, he developed a rigorous management system that allows him to compete at the highest level of professional football. Andrews uses a combination of CGM and insulin pump technology, checks his blood sugar approximately 30 times per game, and keeps sugar-free Gatorade and fruit snacks readily available on the sidelines for quick glucose adjustments.
His success illustrates the importance of preparation and real-time monitoring. Andrews works closely with team medical staff to ensure his diabetes management is integrated into game-day protocols.
Sean Busby - Professional Snowboarder

Nutrition and Hydration Guidelines for Diabetic Athletes
Nutrition for athletes with type 1 diabetes requires balancing three competing demands: fueling athletic performance, maintaining stable blood glucose, and supporting recovery. Unlike non-diabetic athletes who can simply eat for energy, diabetic athletes must consider the glycemic impact of every food choice.
Pre-Exercise Nutrition Strategies
The hour before exercise is critical for establishing stable blood sugar. Athletes should aim for blood glucose levels between 120-180 mg/dL before beginning intense physical activity. If levels are below this range, consuming 15-30 grams of complex carbohydrates can prevent hypoglycemia during exercise.
Recommended pre-exercise foods include:
- Whole grain toast with nut butter
- Greek yogurt with berries
- Oatmeal with protein powder
- Banana with almond butter
During Exercise: Managing Blood Sugar Fluctuations
Exercise intensity and duration dramatically affect blood sugar. High-intensity interval training may initially raise blood glucose due to stress hormone release, while endurance activities typically lower it. Athletes must carry fast-acting carbohydrates for immediate treatment of hypoglycemia:
- Glucose tablets (15 grams recommended)
- Sports drinks with sugar
- Fruit snacks or gummy candies
- Honey packets
Mark Andrews’ strategy of keeping sugar-free Gatorade and fruit snacks available during NFL games exemplifies this approach. He can quickly consume fast-acting carbohydrates when his CGM alerts him to dropping glucose levels.
Post-Exercise Recovery and Glycogen Replenishment
The hours following exercise present unique challenges. Increased insulin sensitivity can persist for 24-48 hours after intense training, increasing hypoglycemia risk. Athletes should:
- Monitor blood sugar closely for 12-24 hours post-exercise
- Consume a combination of carbohydrates and protein within 30-60 minutes
- Consider reducing basal insulin rates overnight after evening training
- Set CGM alarms for overnight low glucose detection
| Timing | Nutritional Goal | Example Foods |
|---|---|---|
| 1-2 hours before exercise | Stabilize blood sugar at 120-180 mg/dL | Whole grain toast with nut butter, Greek yogurt with berries |
| During exercise | Prevent/treat hypoglycemia | Glucose tablets, sports drinks, fruit snacks |
| Within 30-60 minutes post-exercise | Replenish glycogen; support recovery | Chocolate milk, turkey sandwich, protein smoothie with fruit |
| 12-24 hours post-exercise | Prevent delayed hypoglycemia | Regular balanced meals; possible basal rate reduction |
Hydration and Diabetes Management
Proper hydration is crucial for blood sugar management. Dehydration can concentrate blood glucose, leading to misleadingly high readings and potential diabetic ketoacidosis in severe cases. Athletes should:
- Drink water consistently throughout the day, not just during exercise
- Monitor urine color as a hydration indicator
- Consider electrolyte replacement for sessions longer than 60 minutes
- Avoid excessive caffeine which can affect blood sugar and hydration
Psychological and Social Support for Athletes with Type 1 Diabetes
The mental and emotional aspects of managing type 1 diabetes while competing athletically are often underestimated. Athletes face unique psychological challenges that require dedicated support systems.
Mental Health Challenges and Stress Management
Managing type 1 diabetes creates constant cognitive load. According to the Barnstable Brown Diabetes Center, athletes with type 1 diabetes make approximately 200 more medical decisions daily compared to their non-diabetic peers. This decision-making burden includes:
- Calculating insulin doses for meals and corrections
- Interpreting CGM trends and making adjustments
- Balancing exercise intensity with glucose management
- Planning ahead for practices, games, and travel
The constant vigilance can lead to burnout, anxiety, and diabetes distress. Clinical research emphasizes the importance of mental health support as part of comprehensive diabetes care for athletes.
Peer Support and Team Dynamics
The mutual support between high school teammates Braylon Ellis and Andrew Tatum illustrates the power of peer understanding. Both managing type 1 diabetes while playing competitive basketball, they provide encouragement and share management strategies. This peer support reduces feelings of isolation and creates accountability.
Educating coaches, trainers, and teammates about type 1 diabetes is essential. When the entire team understands the condition, athletes feel more comfortable managing their diabetes visibly rather than hiding it, which can be dangerous.
Communication is Key
Athletes should ensure that coaches, athletic trainers, and teammates know how to recognize and respond to hypoglycemia emergencies. Regular communication about glucose levels and management needs prevents misunderstandings and ensures safety.
Building a Comprehensive Care Team
Successful athletic performance with type 1 diabetes requires a multidisciplinary team:
- Endocrinologist: Oversees diabetes management and adjusts medication protocols

Preparing for Competition: Creating a Diabetic Action Plan
Competition day requires meticulous planning. A comprehensive diabetic action plan ensures safety while optimizing performance.
Essential Components of a Diabetic Action Plan
According to clinical care guidelines for athletes with type 1 diabetes, action plans should include:
- Target blood glucose ranges: Specific goals for pre-exercise, during activity, and post-exercise
- Insulin adjustment protocols: How to modify basal rates and bolus doses around training and competition
- Emergency contact information: Healthcare providers, emergency services, and parent/guardian contacts
- Treatment protocols: Step-by-step instructions for managing hypoglycemia and hyperglycemia
- Equipment checklist: CGM supplies, insulin, glucose tablets, backup equipment
Preparticipation Physical Examinations
Athletes with type 1 diabetes should undergo comprehensive preparticipation evaluations that go beyond standard sports physicals. These examinations should assess:
- Cardiovascular health and exercise tolerance
- Diabetic complications screening (retinopathy, neuropathy, nephropathy)
- Current diabetes management effectiveness (A1c levels, glucose variability)
- Technology functionality and proper usage
Communication with Coaches and Officials
Clear communication prevents dangerous situations. Athletes should:
- Inform coaches about their condition and management needs
- Educate officials about potential medical timeouts for glucose checks
- Establish visible signals for low blood sugar that teammates recognize
- Ensure CGM alarms are audible during competition or that a designated person monitors remotely
Emergency Preparedness
All members of the athletic staff should know the location of emergency glucagon and how to administer it. Severe hypoglycemia can progress rapidly during intense physical activity, making preparedness critical.
Travel Considerations for Diabetic Athletes
Athletic competition often involves travel, which presents unique challenges:
- Pack double the supplies needed (insulin, test strips, CGM sensors, pump supplies)
- Carry medical documentation and prescriptions for TSA screening
- Research local medical facilities at competition locations
- Account for time zone changes when programming insulin pumps
- Store insulin properly in temperature-controlled environments
