“Hello! I’m hoping to go on holiday abroad next week and was diagnosed with diabetes. I’m wondering if anyone has experience traveling with diabetes and what to expect. I plan to take a cool bag for my insulin, along with supplies like testing strips, lancets, and my Libre sensor. I’m also wondering about airport procedures—should I carry a letter for my insulin and needles? Will it add extra time to security checks?”. The gene discussed is INS; the disease is diabetes mellitus.
