The festive season in Australia, marked by long, sun-drenched days, vibrant social gatherings, travel, and an abundance of food, is a time for celebration. However, for those living with diabetes, the holiday period can also bring unique challenges. Disrupted routines, tempting treats, increased alcohol consumption, and travel can all affect glucose control and medication management. But with thoughtful planning, it’s entirely possible to enjoy the festivities while keeping your diabetes well-managed. This guide offers practical tips tailored to the Australian summer holidays, helping you stay healthy, safe, and confident throughout the season.

1. Plan for pharmacy closures

Don’t get caught short on medication or supplies.

• Australian pharmacies often close on public holidays such as Christmas, Boxing Day, and New Year’s Day. Some may even have reduced hours leading up to these dates
• Make a checklist of all your diabetes medications, monitoring strips, lancets, needles, and insulin supplies, then ensure you have enough to last until after the holidays. Check everything is in date
• If you require prescription renewals, contact your doctor early in December. Allow extra time for appointments and pharmacy orders, as clinics tend to be busy before the break
• Consider stocking up on emergency hypo treatments, like glucose tablets or gels, and always keep these on hand
• Restock your medicine cabinet with sick day supports such as rehydrating solutions, paracetamol, and band-aids
• Have a list of your just-in-case contacts
• The festive season can be stressful to your body and mind. Keep a written list of your current medications, just in case

2. Stick to your routine (as much as possible)

Consistency is key—even when your schedule changes.

• Social events and travel can mean irregular meals and changes to activity. Try to stay as close as possible to your usual medication and monitoring schedule
• Set daily reminders on your mobile phone, smartwatch, or use a pill organiser to help you remember doses
• If you use insulin, talk to your diabetes educator or doctor about adjusting doses for different mealtimes or activity levels
• Don’t skip doses or double-dose medications. Ask your pharmacist what to do if you miss a dose. Always follow your prescribed regimen unless advised otherwise by a medical professional

3. Be cautious with alcohol and rich foods

Festive indulgence can affect blood glucose levels and interact with medications.

Alcohol and glucose control

• Alcohol can unpredictably raise or lower blood glucose, especially with diabetes medications.
• It may impair liver function and increase hypoglycaemia risk if you use insulin or sulfonylureas (Gliclazide, Glipizide, Glimepiride, Glibenclamide), which stimulate insulin release regardless of food intake

Why hypoglycaemia happens

• The liver stores and releases glucose, but when metabolising alcohol, it prioritises alcohol breakdown over glucose release.
• This can cause delayed hypoglycaemia—often several hours after drinking or overnight.
• Check bedtime glucose levels and watch for symptoms: tremors, sweating, confusion, dizziness.
• Reduce risk by eating carbohydrate-rich foods with alcohol and avoiding drinking on an empty stomach.

Safe drinking tips

• Confirm safe limits with your doctor or pharmacist.
• Drink in moderation and never on an empty stomach.

Managing festive foods

• Celebrations often include rich, high-carb meals—monitor glucose more frequently and expect possible spikes.
• Stay hydrated and consider a walk if levels are high.

Medication safety

• Never adjust insulin or medication without professional advice.
• Consult your healthcare team if unsure about food or alcohol interactions.

Smart snacking

• Carry glucose-friendly snacks like wholegrain crackers or nuts to balance indulgent treats.

GLP-1 medications (Ozempic, Trulicity, Wegovy, Mounjaro)

• These slow gut movement—overeating or heavy drinking can cause nausea, vomiting, reflux.
• Smaller portions usually satisfy; focus on balanced meals with vegetables, lean proteins, and whole grains.
• Drink plenty of water—these medications may reduce thirst.

4. Travel smart

Whether you’re flying interstate or hitting the road, safeguard your medications.

• Always pack your medications and supplies in your carry-on luggage. Checked baggage can be lost, delayed, or exposed to temperature extremes
• Insulin should never be stored in checked bags: temperatures can fluctuate wildly and degrade its potency. Store insulin and GLP-1 medications at a cool temperature, but not in the freezer. Use insulated pouches or cooling wallets when travelling in hot weather
• If travelling internationally, carry a letter from your doctor detailing your diabetes diagnosis, medications, and any devices (such as insulin pumps or continuous glucose monitors). This can be invaluable at airport security or customs
• Bring enough supplies for the entire trip, plus extra in case of delays or emergencies
• Familiarise yourself with pharmacies, medical services, and emergency contacts at your destination

5. Know what to do if you’re unwell

Illness can disrupt blood glucose and change how medications work.

• Have a ‘sick day’ action plan. Discuss with your healthcare provider what to do if you develop fever, vomiting, diarrhoea, or other illnesses
• Sick days may require more frequent blood glucose and ketone monitoring, and adjustments to medication or insulin—only under professional guidance
• Keep in mind that dehydration from illness or heat can increase glucose levels and interfere with medication absorption
• If you’re unsure or if your symptoms worsen, contact your doctor or diabetes educator promptly. Don’t delay seeking help
• Your plan will include where and when to go to seek medical attention. This is especially important if you are away from home

6. Lean on your pharmacist

Pharmacists are a valuable resource during the busy holiday season.

• They can perform medication reviews to check for interactions
• During the holidays, many offer quick health checks, such as blood pressure, which helps maintain overall wellness
• Don’t hesitate to ask for advice about any adverse medication effects, dose timing, or travel tips
• Your pharmacist can also guide you on safe storage and transport of insulin and other medications in hot weather

7. Stay hydrated and sun safe

Australian summers can be scorching. Protect yourself and your medications from the heat.

• Drink plenty of water, especially if you’re outdoors or physically active. Dehydration can affect glucose levels and the effectiveness of your medications
• Limit sugary drinks and alcohol, which can both contribute to dehydration and destabilise blood glucose
• Store insulin and oral medications in cool, shaded areas. Avoid leaving medications in hot cars, direct sunlight, or near barbecues and campfires
• Use sun protection—wear a hat, sunscreen, and light clothing to avoid heat-related illness or stress

8. Navigating celebrations and social events

Enjoy the holidays while keeping your health at the forefront.

• Let trusted friends or family know about your diabetes. In case of a hypo or an emergency
• Don’t feel pressured to overindulge. Choose foods and drinks thoughtfully, and make time for regular movement or walks, which can help stabilise glucose levels
• If meals are delayed, have healthy snacks available to prevent lows. Always carry your medications and glucose treatments when out celebrating
• If you start feeling unwell or notice symptoms like dizziness, confusion, or sweating, check your blood glucose immediately

9. Mental wellbeing and diabetes

The festive season can be stressful—don’t forget to take care of your emotional health too.

• Stress and disrupted sleep can influence blood glucose levels. Try relaxation techniques such as deep breathing, meditation, or gentle exercise to help manage stress
• If you feel overwhelmed, reach out to your diabetes support network or a mental health professional. You’re not alone in navigating holiday challenges

The holiday season in Australia is a time for joy, connection, and adventure. By planning, staying consistent with your medications, monitoring your blood glucose levels, and seeking support from healthcare professionals, you can approach the festivities with confidence.
