Type 1 Diabetes Travel Safety: Understanding How Altitude Affects Insulin Delivery
Understanding the Effects of Altitude on Insulin Delivery
Research indicates that flying with insulin pumps can disrupt the normal regulation of blood sugar levels for individuals with type 1 diabetes. During a commercial flight, altitude changes can influence how effectively pumps deliver insulin to the bloodstream.
Key Findings from Recent Studies
- Insulin pumps may over-deliver insulin during ascent.
- There may be under-delivery of insulin during descent.
- Changes in cabin pressure can affect insulin amounts delivered.
Dr. Ka Siu Fan from the University of Surrey highlights the importance of understanding these dynamics. She advises individuals using insulin pumps to consider disconnecting their pumps before take-off and to clear any air bubbles.
Recommendations for Type 1 Diabetics Flying
- Consult with your doctor about flying affecting blood sugar levels.
- Consider temporarily disconnecting your pump before flying.
- Monitor your blood sugar frequently during the flight.
In the event of cabin decompression, rapid insulin over-delivery could occur. To counteract this, consuming fast-acting carbohydrates can help.
