Travelling can be lots of fun and having diabetes shouldn’t stop you. With sensible planning, people with diabetes can start their journey with confidence and be equipped with the knowledge and skills to keep their diabetes in check.

Travelling with type 2 diabetes

The pancreas is an organ in the body that produces a hormone called insulin, which helps to take the glucose from the blood into our body cells. For people with type 1 diabetes, the pancreas doesn’t produce any insulin. They require life-long insulin injections. For people with type 2 diabetes the pancreas produces some insulin, but not sufficient amounts. In addition, the insulin that is produced may not work effectively to move the glucose out of the blood. This results in high levels of sugar in the blood. People with type 2 diabetes can usually control their blood sugars with diet alone, or diet plus medication.

People with poor control of their blood sugars may also experience low blood sugar levels also known as hypoglycaemia. Symptoms include dizziness, confusion, headache, feeling faint, sweating, chills or even loss of consciousness. This can be dangerous, and regular blood sugar monitoring is advised.

Whether you control your diabetes using diet alone, or you take additional medication, eating foods throughout the day, which are low in fat and have a low ‘glycaemic index’ (GI) will help to control blood sugars. Foods with a low GI are absorbed slowly into the body, helping to maintain your blood sugar at a steady level.

How to travel if you have diabetes:

  • See your health care provider before you leave to discuss your trip, your medication and dietary requirements. Some medications can cause hypoglycaemia, so be aware of what you are taking. Continue to take your regular medication while away and make sure you have more than enough for your trip. Your blood sugars should be well controlled before you leave.
  • For the flight, ring the airline in advance to arrange an appropriate diabetic/low fat meal. Also take some healthy low GI snacks in your carry-on luggage in case your meal is delayed, or the carbohydrate portion is small. Healthy snacks include wholegrain sandwiches, muesli bars, plain crackers or dried fruit/nut mix. It is also important to have some quick-acting carbohydrate snacks on hand such as jelly beans, glucose gels, fruit juice in case of unexpected hypoglycaemia.

Travelling with type 2 diabetes

  • Research your destination and the foods available. Most places will have basic carbohydrate foods such as bread, pasta and rice. Ensure you have a regular intake of low GI foods at each meal. Some countries will have foods that may affect your blood sugar unpredictably, so it’s a good idea to regularly monitor using a glucose meter.
  • In the event of hypoglycaemia, have some fast-acting low GI carbohydrate immediately. Make sure you follow this with a low GI meal/snack to ensure your blood sugar is maintained at an appropriate level.
  • Exercise is an excellent way to help improve your diabetes control however, it can cause your blood sugars to go down. If you are sightseeing or hiking be sure to have low GI meals and snacks regularly through the day. Have healthy low GI snacks available in your day-pack to help maintain blood sugars. Also carry some fast acting snacks such as jelly beans if your sugars go too low.

Travelling with type 2 diabetes

When you are unwell with a virus or infection, your blood sugars usually rise. You should monitor your blood sugars more regularly. Try to eat your regular meals and snacks. If you are finding it difficult to eat, then you should try and have small snacks and drinks containing carbohydrates every two hours.

As always, seek medical attention if required. Know where your nearest medical centre is in case of emergency.
