Diabetes Management Simulator (USA)
Simulate insulin dosing using the standard formula: Insulin Dose = (Carbohydrates - Basal Insulin) / Insulin Sensitivity
How to Calculate Insulin Dose
The standard formula for calculating insulin dose is:
This formula helps determine the amount of insulin needed based on carbohydrate intake and individual sensitivity.
- Carbohydrates: Amount of carbs in grams to be consumed
- Basal Insulin: Background insulin level
- Insulin Sensitivity: How many carbs are covered by 1 unit of insulin
- Insulin Dose: Calculated units of insulin needed

Diabetes Management Recommendations
Based on your simulated parameters:
- Your insulin sensitivity appears to be in a reasonable range
- Continue monitoring blood glucose before and after meals
- Adjust insulin doses based on actual glucose readings
- Consider timing of insulin relative to meal consumption
Understanding Diabetes Management
Insulin sensitivity refers to how much your blood glucose levels decrease in response to insulin. It varies between individuals and can be influenced by factors such as activity level, time of day, and overall health. Understanding your insulin sensitivity is crucial for effective diabetes management.
The insulin dose calculation helps determine how much insulin to take based on carbohydrate intake:
This formula provides a starting point for insulin dosing, but should always be adjusted based on actual glucose readings and physician guidance.
This simulator provides educational estimates only. Actual insulin dosing should always be determined by healthcare professionals based on individual patient needs. Never adjust insulin doses without medical supervision. Hypoglycemia and hyperglycemia can be dangerous and require immediate medical attention.
Diabetes Management Quiz
If a patient plans to eat 60g of carbohydrates, has a basal insulin of 3 units, and an insulin sensitivity of 1:15, what is the recommended insulin dose?
Insulin Dose = (Carbohydrates - Basal Insulin) / Insulin Sensitivity
Insulin Dose = (60 - 3) / 15
Insulin Dose = 57 / 15 = 3.8 units
The recommended insulin dose is approximately 3.8 units.
This calculation demonstrates the application of the formula. Note that basal insulin is subtracted from carbohydrates before dividing by sensitivity.
What does an insulin sensitivity factor of 1:15 mean?
An insulin sensitivity factor of 1:15 means that 1 unit of insulin will cover approximately 15 grams of carbohydrates. This factor varies between individuals and may need adjustment based on activity, time of day, and other factors.
Common ranges:
- High sensitivity: 1:20 or higher
- Moderate sensitivity: 1:15-1:20
- Low sensitivity: 1:10-1:15
- Insulin resistance: 1:5-1:10
What is the typical threshold for hypoglycemia in diabetes management?
Hypoglycemia is typically defined as a blood glucose level below 70 mg/dL. This is considered dangerous and requires immediate treatment with fast-acting carbohydrates.
What is the target post-meal glucose level for most people with diabetes?
The target post-meal glucose level for most people with diabetes is less than 180 mg/dL (measured 1-2 hours after the start of a meal). Some individuals may have tighter targets as determined by their healthcare provider.
Goals:
- Pre-meal: 80-130 mg/dL
- Post-meal: Less than 180 mg/dL
- HbA1c: Below 7% (individualized)
Which type of insulin is typically used for meal coverage?
Rapid-acting insulin (such as lispro, aspart, or glulisine) is typically used for meal coverage. This type of insulin starts working within 15 minutes, peaks in 1-2 hours, and lasts for 3-4 hours, making it ideal for controlling post-meal glucose spikes.
Other types include:
- Short-acting (regular): Used for meal coverage but slower onset
- Intermediate-acting: Provides basal coverage
- Long-acting: Provides steady basal coverage
Q&A
Q: How do I determine my personal insulin sensitivity factor?
A: Determining your personal insulin sensitivity factor (ISF) requires systematic testing:
Method 1 - Correction Testing:
- Wait for high glucose: Test when glucose is 200-250 mg/dL
- Take correction dose: Based on suspected ISF
- Monitor for 3-4 hours: Note glucose drop
- Calculate: If 5 units dropped glucose by 100 mg/dL, ISF = 1:20
Method 2 - Meal Testing:
- Consistent carb intake: Eat same amount of carbs
- Same insulin dose: Use same dose each time
- Monitor results: Track glucose response
- Adjust accordingly: Modify dose based on outcomes
Important Notes:
- Test one factor at a time
- Keep activity and other factors consistent
- Work with healthcare team for safety
- Factors like stress and illness affect ISF
Always work with your healthcare provider when adjusting insulin sensitivity factors.
Q: What are the signs of hypoglycemia and how should it be treated?
A: Recognizing and treating hypoglycemia quickly is critical:
Early Signs:
- Physical: Shakiness, sweating, hunger, dizziness
- Neurological: Confusion, irritability, anxiety
- Behavioral: Mood changes, difficulty concentrating
Advanced Signs:
- Severe confusion: Inability to think clearly
- Seizures: In extreme cases
- Loss of consciousness: Requires emergency glucagon
Treatment - Rule of 15:
- Check glucose: If below 70 mg/dL
- Give 15g carbs: Glucose tablets, juice, or candy
- Wait 15 minutes: Recheck glucose
- Repeat if needed: Until glucose >70 mg/dL
Prevention:
- Regular meal timing
- Carry fast-acting carbs
- Monitor glucose frequently
- Adjust insulin for activity levels
Always have glucagon available for severe hypoglycemia.
Q: How does exercise affect insulin sensitivity and glucose levels?
A: Exercise significantly impacts glucose management in diabetes:
Immediate Effects:
- Increased uptake: Muscles use glucose more efficiently
- Enhanced sensitivity: Cells become more responsive to insulin
- Glucose utilization: Exercise can lower glucose for 2-24 hours
Exercise Types:
- Aerobic: Generally lowers glucose (running, cycling)
- Resistance: May initially raise glucose then lower it
- High-intensity: Can cause temporary glucose rise
Management Strategies:
- Pre-exercise: Check glucose and adjust if needed
- During: Monitor for prolonged activities
- Post-exercise: Be aware of delayed hypoglycemia
- Insulin timing: Consider reducing pre-exercise insulin
Important: Exercise guidelines should be individualized based on your specific diabetes management plan.
