Causes
Main causes
- Time zone changes can shift when you eat, sleep, and take diabetes medicines.
- Being on a plane, train, or car for hours can change your activity level and risk of lows or highs.
- Local foods and unfamiliar meal times can make it harder to match food to your diabetes management plan.
- Stress from travel, changes in routine, and feeling excited can also affect blood sugar.
- Illness, like catching a cold or stomach bug, can cause blood sugar to swing unpredictably.
Risk factors
- Long journeys with limited access to food or bathrooms
- Extreme weather, such as very hot or cold destinations
- Eating unfamiliar foods or drinking alcohol
- Traveling alone without someone who knows you have diabetes
- Having had recent episodes of low blood sugar
- Already having diabetes-related foot problems or vision changes
When to see a doctor
See a doctor urgently if:
- Get urgent medical help if you feel too ill to manage your diabetes, if you are sick for more than a day and cannot keep fluids down, or if you have severe symptoms like confusion or trouble breathing.
Book a routine appointment if:
- See your healthcare provider 4 to 6 weeks before a trip for a general diabetes review.
- Check if your travel vaccines are up to date, and ask about insurance that covers diabetes care abroad.
- Talk to your diabetes nurse or doctor about adjusting your diabetes medicines for time zone changes.
Diagnosis
Traveling with diabetes does not require a new diagnosis. However, if you are unsure how well your diabetes is controlled, your healthcare provider can check your blood sugar levels and may review your recent results. This is often done as part of a pre-travel check-up.
Tests that may be done
- Blood sugar measurement (a finger-prick test or sensor reading)
- HbA1c blood test to show your average blood sugar over the past 2 to 3 months
- Kidney and eye checks if you have had diabetes for several years
- A foot examination to check for numbness, sores, or poor circulation
What to expect at your appointment
Your healthcare provider will discuss your travel plans, review your current diabetes medicines, and give you practical advice about adjusting doses for time zones. They may also provide a letter listing your medicines and any medical devices, which can be helpful at airport security.
Treatment
Managing diabetes while traveling is mostly about keeping your usual treatment routine as close to normal as possible, even when your schedule changes. This includes monitoring your blood sugar more often, eating regularly, and staying active in a safe way.
Self-care at home
- Pack at least double your normal supply of diabetes medicines, testing strips, and device batteries.
- Keep all diabetes supplies in your carry-on bag, not in checked luggage.
- Store insulin properly; do not let it freeze or get too hot.
- Carry fast-acting sugar, such as glucose tablets, fruit juice, or candy, for hypos.
- Plan for meals and snacks, and try to tell a travel companion what to do if you have a severe low blood sugar.
- Check your feet daily and treat any blisters or cuts promptly.
Medical treatments
Your usual diabetes treatment may include medicines such as insulin or other blood sugar-lowering medications, along with blood sugar monitoring. Your healthcare provider can help you adjust the timing and doses for travel across time zones. Do not make any changes without speaking to them first. If you use a pump or continuous glucose monitor, pack extra supplies and a backup plan in case devices fail.
When is surgery considered?
Surgery is not usually part of traveling with diabetes. However, if you plan a medical procedure while abroad, your usual diabetes management will need to be adjusted by a local healthcare provider. Always plan any medical care well in advance.
Living with this condition
When traveling, try to keep your usual routine for meals, medication, and sleep as steady as possible. Check your blood sugar before and during flights, and again before you drive or walk long distances. It also helps to learn the local emergency number and the word for 'diabetes' in the local language.
Lifestyle tips
- Stay hydrated with water; limit sugary drinks and high-dose caffeine.
- Move every couple of hours on long flights or road trips to support circulation.
- Be extra careful with your feet if you walk a lot or wear new shoes.
- Wear comfortable, well-fitting shoes and break them in before your trip.
- Take time to rest and avoid over-scheduling your days.
Diet and exercise
Try to balance your meals as you usually do. Choose foods that are close to your normal routine, and be mindful of portion sizes when trying local dishes. If you are more active than usual, such as walking around a city, you may need extra snacks to prevent low blood sugar. Gentle daily activity can also help your body use insulin better.
Mental health and emotional wellbeing
Traveling with diabetes can feel stressful, especially if you worry about emergencies. It is normal to feel anxious. Allow yourself extra time, be kind to yourself, and tell someone you trust about your concerns. If you feel very anxious or low, speak to a healthcare professional.
Prevention
You cannot prevent diabetes itself, but you can prevent most travel-related problems with careful planning. Pre-travel checks, packing enough medicine, and checking your blood sugar regularly can help you catch and treat issues early.
Vaccines
Depending on your destination, you may need travel vaccines. Having diabetes should not stop you from getting them, but discuss any concerns with your healthcare provider. Fever from any illness can affect your blood sugar, so monitor closely if you feel unwell.
Screening programmes
Before traveling, ask for a check-up, especially if you have had diabetes-related complications. This may include a foot check, kidney blood test, and eye check to ensure you are fit to travel.
Complications
If left untreated
- Severe low blood sugar (hypoglycemia), which can cause confusion, seizures, or unconsciousness
- Severe high blood sugar (hyperglycemia), which can lead to dehydration and, if untreated, a serious condition called diabetic ketoacidosis
- Blood clots in the legs during long periods of immobility
- Worsening of foot problems if shoes rub and blisters are ignored
- Infections that become serious because they are not treated promptly
Long-term outlook
With proper preparation, travel can be a wonderful experience for people with diabetes. Although there are extra things to think about, most diabetes-related travel issues can be prevented or managed without drama. A little planning gives you freedom to explore, relax, and enjoy your trip.
