5 tips for traveling when you have a chronic disease

(BPT) - Finding out you have a chronic illness is challenging, but it can be particularly traumatic when it happens far away from home. That's exactly what happened to Gretchen when she was 23 years old during what was supposed to be a dream international trip.

A cruise across the Mediterranean took an unexpected turn when Gretchen suddenly became severely ill, experiencing decreased appetite and dehydration. She thought she might have a minor travel-related sickness or infection and visited the ship's physician for care. After running a battery of tests, the doctor delivered a surprising diagnosis. Gretchen had Type 1 diabetes (T1D) and, at that moment, was experiencing diabetic ketoacidosis (DKA), a life-threatening condition that occurs in people with diabetes when ketone levels are too high. For people living with diabetes, their ketones reach dangerously high levels when their body is not able to use glucose as fuel due to a lack of insulin, so instead, the body breaks down fat too quickly, which in turn produces ketones in the blood stream.¹ A DKA event, like the one Gretchen experienced, is how many people find out they have T1D, which accounts for about 20% to 40% of DKA cases.¹

Ambiguous DKA symptoms can delay treatment

For people with diabetes who use insulin, elevated or high ketone levels can lead to DKA, a serious health condition that is on the rise.¹ A study showed that between 2017 and 2024, DKA prevalence among people with Type 1 diabetes increased approximately 24%,² rising from 50 to 62 cases per 1,000 individuals.² DKA is particularly dangerous because in severe cases it can lead to a coma or death.¹ Unfortunately, many patients don't detect it early enough, mistaking their symptoms for other, more common illnesses like the flu, dehydration or food poisoning.^4,5,6

According to Eden Miller, DO, a family practitioner and diabetologist, there are clear reasons behind this alarming trend. "Part of the problem lies in how difficult it can be to distinguish DKA symptoms from less serious, run-of-the-mill medical conditions," said Dr. Miller. "The other part is the underutilization of ketone monitoring methods. While glucose monitoring has advanced, ketones and glucose do not always rise together, and current monitoring tools don't provide continuous visibility into rising ketones. Together, these issues can delay critical treatment."

This trend highlights a clear gap for people living with diabetes. Instead of patients feeling equipped with the insights they need to be proactive and prepared, they are left in a reactive state.

"Improving awareness of DKA and helping people understand what to do when ketones are rising are important opportunities to help reduce DKA risk," said Miller.

Getting treated and gaining confidence

Initially overwhelmed by the diagnosis, once back in the U.S., Gretchen visited an endocrinologist who introduced her to modern diabetes management tools - like Abbott's FreeStyle Libre 3 Plus sensor which continuously measures her glucose levels - and helped guide her through the initial steps of how to live with diabetes. While learning the basics of living with diabetes, Gretchen also learned about ketones, the importance of recognizing DKA symptoms and how to act quickly during a DKA event.

"My diagnosis was a wake-up call, but it wasn't a stop sign. Managing a chronic condition like diabetes doesn't mean shrinking your world; it just means packing a little smarter. By taking control of my health and having a proactive plan, I've reclaimed my love for travel. I want other people to know that living with chronic illnesses shouldn't keep you from making plans, booking trips and living fully."

Tips to keep diabetes management top of mind for travel

Gretchen's experience during her European holiday inspired her to create her own diabetes travel guide to help herself and others living with diabetes proactively plan and diligently monitor their condition, so their vacations stay on track. Below are her top tips for traveling safely and confidently with diabetes.

1. Always stay hydrated: Drink plenty of water, especially when traveling in warm weather and during physical activity like walking through new cities.
2. Pack smart and double up: It's always a good idea to carry extra medications and supplies. This includes insulin, pumps, needles, automated insulin delivery (AID) infusion sets and ketone testing supplies - including blood or urine test strips. Be sure to check the expiration date before packing! Also, bringing a doctor's note can help too in case you get stopped or questioned while traveling with your supplies.
3. Monitor more, adjust often: Travel means changes to your routine. To make sure you stay on top of your diabetes management, check your glucose monitor, pumps and sensors more frequently.
4. Know the signs, act fast: Signs that you may be experiencing a DKA event include extreme thirst, frequent urination, nausea, abdominal pain or fruity-smelling breath. If you experience any of these symptoms, check your glucose and test for ketones immediately.
5. Seek care: When traveling, find the nearest pharmacy or urgent care in case you need medical attention during your trip.

Don't let fear of managing diabetes keep you from seeing the world. Using these tips, you can stay prepared to explore new horizons safely and confidently.

If you or someone you know is living with diabetes, work with a healthcare provider to create a proactive DKA plan so you can feel confident in knowing what to do when ketones are rising or you are not feeling well. For more information about DKA, go to RisingKetones.com.
