International travel has become routine for millions of people, but unexpected disruptions such as flight cancellations, airspace closures, or sudden delays can create serious challenges for individuals living with chronic health conditions. For patients who rely on daily medications or medical devices to manage diseases such as diabetes, thyroid disorders, or hypertension, even a short interruption in treatment can lead to significant health risks.
Healthcare experts say that continuity of care becomes critical in such situations. Patients stranded in unfamiliar locations may struggle to access medications, monitoring devices, or medical guidance, increasing the risk of complications.
According to Dr Ihsan Almarzooqi, Co-Founder and Managing Director of Metabolic (formerly GluCare.Health), travel disruptions can create a cascade of health challenges if treatment routines are interrupted.
The hidden risks
Chronic disease management depends heavily on consistency. When medications are suddenly unavailable, the body can quickly fall out of balance, particularly for patients managing metabolic conditions.
Dr Ihsan explains that the consequences vary depending on the illness but the underlying problem remains the same.
“When access to essential medications is suddenly interrupted, the immediate risks depend on the condition, but the underlying issue is the same: physiological stability of key metabolic health markers can deteriorate quickly when chronic disease management is disrupted,” he says.
For people living with diabetes, the impact can be immediate and severe.
“Even a short interruption in insulin or glucose-lowering medications can lead to significant glucose instability. In some cases, particularly for insulin-dependent patients, this can escalate into acute complications if not addressed promptly,” he notes.
Other conditions may appear less urgent but still carry risks. Missing medication for hypertension, thyroid disorders, or cardiovascular conditions can cause dangerous internal shifts.
“Missing medications may not produce immediate symptoms, but it can still trigger dangerous physiological shifts, including rising blood pressure, fluid imbalance, or hormonal disruption, especially when combined with travel stress, dehydration, sleep disruption, and changes in routine,” he says.
Travel disruptions often amplify these risks because multiple destabilising factors occur at the same time.
“Missed medications, irregular meals, poor sleep, stress, and limited access to monitoring tools or medical guidance can all converge at once,” Dr Ihsan explains.
What stranded patients should do
When travelers with chronic illnesses find themselves unexpectedly stranded in another country, quick action can help prevent medical emergencies.
The most important step, experts say, is maintaining medication routines.
“The first priority is maintaining medication schedules and monitoring vital signs as closely as possible. When travel disruptions occur, the most important step is to avoid gaps in treatment, even if that means temporarily working with a local healthcare provider rather than your usual doctor,” says Dr Ihsan.
Access to medical records can make this process significantly easier.
“Having a clear record of medications, dosages, and medical history is extremely helpful in these situations, as it allows another physician to quickly understand the patient’s condition and safely continue treatment,” he explains.
Patients with diabetes may face additional complications because their treatment often relies on a combination of medications, devices, and specialised consumables.
“Many type 1 diabetes patients use insulin pumps or continuous glucose monitors. There might be regional setting restrictions with these devices when using consumables from another region, so it is best to seek help from a specialist diabetes clinic,” he advises.
Ultimately, restoring routine becomes the primary goal.
“The key is restoring routine as quickly as possible, keeping medications consistent, monitoring the condition closely, and seeking medical guidance early rather than waiting for symptoms to escalate,” Dr Ihsan says.
Supply challenges for complex treatments
While many medications are widely available, endocrine and metabolic therapies can be more difficult to source quickly, particularly when patients are outside their home country.
Dr Ihsan explains that treatments such as insulin, GLP-1 medications, thyroid therapies, and hormonal treatments often require careful clinical oversight.
“Many endocrine and metabolic treatments are more complex than standard medications, which makes continuity planning especially important,” he says.
Devices that support these treatments, including continuous glucose monitors and insulin pumps, also add another layer of complexity.
“These devices can require specific prescriptions, configurations, or clinical oversight, which can make them harder to access quickly when travel disruptions occur,” he notes.
Medication supply chains can vary significantly between countries, meaning patients may not find the exact formulations or doses they usually take.
“Local pharmacies may not carry the exact medication formulation, dose, or device compatibility a patient normally uses, and some medications may fall under controlled categories, making them harder to obtain quickly in another country,” Dr Ihsan explains.
To address this challenge, healthcare providers can play a proactive role by maintaining adequate supplies and offering rapid consultation services.
“Specialised clinics should maintain adequate stock of critical medications and devices, and establish rapid-access consultation pathways so physicians can quickly stabilise patients until normal care resumes,” he says.
The expanding role of telemedicine
Digital healthcare solutions have become an essential tool for maintaining treatment continuity, particularly during unexpected travel disruptions.
Telemedicine allows patients to connect with physicians remotely, enabling quick assessments and guidance even when patients are far from their regular healthcare providers.
“Telemedicine plays a critical role in maintaining continuity of care when patients suddenly lose access to the healthcare providers who understand their medical history, medications, and treatment plan,” says Dr Ihsan.
However, he believes telemedicine is most effective when combined with a broader hybrid care approach.
“Often, a standard telemedicine consultation provides only a single snapshot of the patient’s condition. Telemedicine works best as part of a hybrid model where physicians can also access data from connected devices,” he explains.
Devices such as insulin pumps and continuous glucose monitors can transmit real-time health data to physicians, allowing more informed decision-making.
“Through these tools, key metabolic health markers including glucose, nutrition, sleep, stress, and physical activity can be analysed, enabling personalised guidance and temporary treatment adjustments,” he says.
Lessons for travelers with chronic illnesses
For patients managing long-term health conditions, careful planning before international travel can help prevent disruptions from turning into medical emergencies.
Dr Ihsan advises travelers to treat healthcare preparation as an essential part of trip planning.
“Travelers with chronic conditions should think about healthcare planning in the same way they think about travel insurance or passport validity, as a routine part of preparation,” he says.
One of the most important precautions is carrying additional medication.
“Ideally, patients should travel with extra medication beyond the planned duration of their trip, along with copies of prescriptions and a simple record of their medical history,” he advises.
This preparation becomes particularly important because medication availability varies widely between countries.
“Some medications that are commonly prescribed abroad may not be widely available in the region, may require special approval, or may be classified as restricted depending on local regulations,” he notes.
The same applies to medical devices, which may have region-specific configurations or software compatibility.

Building resilient healthcare systems
As global travel continues to grow, healthcare systems and policymakers may need to rethink how to support patients who face unexpected treatment interruptions abroad.
Dr Ihsan believes that cross-border continuity of care should become a priority.
“Patients often travel with highly individualised treatment plans, yet healthcare systems can be fragmented when someone suddenly requires care in another country,” he says.
Improving coordination between healthcare providers, digital health platforms, and policymakers could help address this issue.
“Streamlining processes around prescription continuity, telemedicine consultations, and access to medical records can make a significant difference when patients require care outside their home country,” he explains.
Hybrid healthcare models that combine in-person care, remote monitoring, and digital consultations may also help bridge these gaps.
“Clinics that combine in-person care with remote consultations, home visits, and digital monitoring are often better positioned to respond quickly when patients require urgent support outside their usual care pathway,” Dr Ihsan says.
Ultimately, he believes healthcare systems must be designed to remain flexible during disruptions.
“The goal is to provide a safe bridge of care when unexpected events occur. When healthcare providers, policymakers, and digital health platforms work together, patients can continue managing their conditions safely even during travel disruptions,” he concludes.
