Research has shown that altitude changes during commercial flights can impact the blood glucose levels of people with type 1 diabetes using insulin pump therapy. Insulin delivery from pumps was tested in a hypobaric chamber to mimic flight conditions, with results showing minor fluctuations in insulin over-delivery during ascent and under-delivery during descent. Rapid decompression could lead to a significant insulin overdose, potentially causing hypoglycemia. To mitigate risks, individuals using insulin pumps are advised to temporarily disconnect their pumps before takeoff and ensure proper insulin delivery during flight by removing air bubbles. This information highlights the importance of managing insulin delivery during air travel for individuals with type 1 diabetes.
