Managing Type 1 Diabetes During Infections: Necessary Changes to Daily Routines


Managing type 1 diabetes can be a daily challenge, and this challenge can become even more complex during periods of infection. Infection-related stressors, such as fever, changes in appetite, and medication adjustments, can significantly impact blood sugar control. In this comprehensive guide, we will explore the essential changes that clients with type 1 diabetes may need to make in their daily routines when dealing with infections. Understanding these adjustments is crucial for individuals with type 1 diabetes, their caregivers, and healthcare providers to ensure effective diabetes management during illness.

Type 1 Diabetes and Infection: A Complicated Balance:

Type 1 diabetes is an autoimmune condition characterized by the body’s inability to produce insulin, leading to elevated blood sugar levels. During infections, managing blood sugar becomes even more critical, as the body’s response to illness can affect insulin sensitivity and requirements. Clients with type 1 diabetes must navigate this delicate balance by making specific changes to their daily routines to ensure their health and well-being during illness.

Essential Changes to Daily Routines During Infections:

  1. Frequent Blood Sugar Monitoring:
    • Rationale: During infections, blood sugar levels can become erratic due to various factors, including stress hormones and changes in eating habits. Frequent blood sugar checks (at least every 2-4 hours) are essential to track fluctuations and adjust insulin doses accordingly.
  2. Hydration:
    • Rationale: Fever, increased urination, and sweating during illness can lead to dehydration, potentially causing blood sugar levels to rise. Clients should prioritize staying hydrated by drinking water or sugar-free fluids.
  3. Adjusting Insulin Dosages:
    • Rationale: Insulin needs may fluctuate during infections. Clients should work closely with their healthcare providers to determine whether insulin doses need to be adjusted. This may involve increasing basal insulin, adjusting mealtime insulin, or using correction doses.
  4. Regular Meals and Snacks:
    • Rationale: Maintaining a consistent eating schedule is crucial for blood sugar stability. Clients should aim to consume regular meals and snacks, even if their appetite is reduced. Choosing foods that are easy to digest and lower in carbohydrates can help manage blood sugar levels.
  5. Sick-Day Management Plan:
    • Rationale: Clients should have a sick-day management plan in place, which includes clear guidelines on insulin adjustments, monitoring frequency, and when to seek medical attention. This plan should be discussed with their healthcare provider.
  6. Rest and Self-Care:
    • Rationale: Rest is essential for recovery during illness. Clients should prioritize self-care and ensure they get adequate sleep and rest to support their overall well-being.
  7. Medication Adherence:
    • Rationale: Clients should continue taking prescribed medications, including insulin, as directed by their healthcare provider. Skipping doses can lead to uncontrolled blood sugar levels and worsen the effects of infection.


Managing type 1 diabetes during infections requires careful adjustments to daily routines. Clients should prioritize frequent blood sugar monitoring, hydration, insulin dosage adjustments, regular meals and snacks, a sick-day management plan, rest, and medication adherence. These changes, when implemented with guidance from healthcare providers, can help individuals with type 1 diabetes effectively manage their condition during periods of illness.
