Living with Chronic Kidney Disease (CKD) or having a kidney transplant shouldn’t stop you from exploring the world. Most people can travel safely with the right preparation.
Whether you are managing Stage 3 CKD or are a “Kidney Warrior” on the move, these 10 tips will help you travel with confidence.
In the digital age, carrying a thick folder of paper records is outdated. Use the Patients Know Best (PKB) website to keep your latest GFR, blood pressure readings, and medication lists on your smartphone. Having your data accessible offline or via a secure portal ensures that if you need to see a doctor abroad, they have the exact medical context they need.
Never pack just enough medication for the trip. Flight delays, lost luggage, or unexpected extensions happen.
The Rule: Pack a double supply of all tablets and injections.
The Location: Always keep medications in your hand luggage. Never check them into the hold, where temperatures fluctuate and bags can go missing.
Maintaining stable kidney perfusion is vital.
Hydration: Drink plenty of water, but be mindful of your specific fluid restrictions if you have advanced CKD.
The Sun: Immunosuppressant medications for transplant patients significantly increase the risk of skin cancer.
Action: Wear SPF 50+, a wide-brimmed hat, and long sleeves. Avoid the midday sun (11 am – 3 pm).
Eating out is part of the fun, but restaurant food is often hidden with high sodium and potassium.
Tip: Look for “Lower Salt” options on menus.
Snack Hack: Carry your own low-potassium snacks (like apples or plain crackers) to avoid being forced into eating high-salt airport food.
Standard travel insurance often excludes “pre-existing conditions” unless explicitly declared.
The Advice: Use a specialist insurer that covers CKD or transplantation. Failing to declare your condition can lead to astronomical medical bills if you require treatment abroad.
Before booking your hotel, locate the nearest Hospital with a Renal Unit. While you likely won’t need it, knowing it is 10 minutes away rather than two hours away provides immense peace of mind.
Carry a formal “Letter of Clinical Necessity” from your nephrologist. This letter should:
List your diagnosis and current medications.
Explain any medical equipment you are carrying (e.g., needles/syringes for EPO).
Provide your consultant’s emergency contact details.
Don’t rely on how you “feel.” Changes in altitude, diet, and temperature can affect your body.
Equipment: Pack a portable blood pressure cuff and, if you are diabetic, your glucose monitor.
Check Daily: Look for new swelling (oedema) in your ankles or any unusual shortness of breath.
If possible, travel with a companion who understands your condition. Ensure they know where you keep your medical letter and how to access your PKB profile in case of an emergency.
Travel fatigue is real, and for CKD patients, it can be more pronounced.
Schedule: Plan “rest days” between heavy sightseeing.
Listen to your body: It is okay to skip a tour if you feel tired. As our friend Darren Daniel (the Kidney Warrior) says: “It’s okay to break the rules occasionally—just don’t break the kidneys!”

Traveling with CKD is about preparation over perspiration. By planning ahead, staying hydrated, and keeping your medical data at your fingertips, you can enjoy your holiday just like anyone else.
