You have flown to Medellín, unpacked, had your pre-operative tests and met your surgeon in person. Then you hear the words nobody plans for: "We need to wait." It is disappointing, expensive and sometimes upsetting. It can also be the moment a surgical team shows it takes your safety seriously. This article explains why postponements happen, what you can do before you fly to make them less likely, and how to structure your trip so a delay is a setback rather than a disaster.
First, a change in mindset
When you book surgery abroad, it is natural to think of the surgery date as fixed and everything else as arranged around it. In reality, the date is provisional until the surgeon and anesthesiologist have examined you and reviewed your results in Medellín. A surgical team that would never postpone, whatever your labs showed, is not the team you want.
The NHS describes a good consultation as one in which the surgeon explains the procedure, its limits, the alternatives and the risks, and suggests a cooling-off period before going ahead (NHS, accessed 2026). Built into that idea is the possibility that the answer, on the day, could be "not yet."
The usual reasons surgery is put on hold
Postponements tend to fall into a few categories. Most are about safety, and most are foreseeable to some degree.
| Category | Examples | Can you reduce the odds? |
|---|---|---|
| Lab results | Low hemoglobin, abnormal blood sugar, clotting values outside the expected range | Often, by testing at home first |
| Undisclosed or changed medications | Blood thinners, supplements affecting bleeding, medications that affect anesthesia | Yes, through full disclosure early |
| Nicotine | A positive nicotine test, or admitted recent use | Yes, by stopping when told and being honest |
| Acute illness | A cold, chest infection, stomach bug or fever around surgery day | Partly, by protecting your health before travel |
| Findings at examination | Anatomy or skin quality different from what the photos suggested | Partly, through better photos and an honest history |
| Clinic-side issues | Surgeon or anesthesiologist unavailable, facility problem | Not directly, but terms can protect you |
Lab results
Pre-operative blood tests exist to catch problems before they become emergencies in the operating room. A result that looks fine to you may make an anesthesiologist uneasy for a long operation. Low hemoglobin is one of the most common examples, and our article on pre-op anemia covers it in depth.
Medications and supplements
Surgeons commonly ask patients to stop certain medications and supplements before surgery, especially those that affect bleeding. Mayo Clinic's patient guidance for several plastic surgery procedures, for example, mentions stopping aspirin, anti-inflammatory drugs and some herbal supplements as directed by the surgical team (Mayo Clinic, accessed 2026). If you forget to mention a supplement, or keep taking something you were told to stop, the team may decide it is not safe to proceed. Newer medications, such as weight-loss injections, also matter to the anesthesia team.
Nicotine
Many Medellín surgeons ask patients to stop all nicotine well before surgery, and some test for it. A positive result can mean the operation is postponed, because nicotine impairs blood flow and healing. Be truthful about vapes, pouches and gum as well as cigarettes. See our nicotine testing article for more.
Getting sick
Travel exposes you to airports, planes and new food, all in the days before surgery. A respiratory infection or stomach bug can make anesthesia riskier. The CDC Yellow Book recommends seeing a travel medicine clinician roughly a month to six weeks ahead of medical travel and recommends being up to date on routine vaccines (CDC Yellow Book, 2026). Tell your team promptly if you feel unwell after arriving. Hiding a fever to protect your surgery date puts you at risk.
Before you fly: lowering the odds
A large share of postponements can be anticipated with good preparation at home.
- Ask for the full pre-op test list early. Find out exactly which blood tests and other checks your surgeon requires, and the acceptable timing.
- Consider testing at home first. If your surgeon agrees, having key tests done with your own doctor a few weeks before travel gives you time to correct problems before you have spent money on flights.
- Send a complete medication and supplement list, and ask in writing what to stop and when.
- Tell the truth about nicotine, alcohol and other substances. Your team can only plan for what they know.
- Talk to your own doctor. The CDC recommends speaking with a primary care clinician well before medical travel and making sure you have enough of your regular medications for the whole trip.
- Disclose chronic conditions and past anesthesia problems at the virtual consultation, not on arrival.
- Protect your health in the final week. Rest, eat well and avoid situations where you are likely to catch something.
Building a trip that can absorb a delay
Even with perfect preparation, some postponements happen. The aim is to plan so a delay is manageable.
Arrive with a margin
Arriving the night before surgery leaves no room for a lab result to be repeated or a minor issue to be addressed. Ask your surgeon how many days before surgery they want you in Medellín, and consider adding a buffer.
Flexible flights and accommodation
A changeable return ticket costs more than the cheapest fare, but the price of rebooking a rigid ticket at short notice can be far higher. Look for flexible terms on accommodation too, especially if you have booked a recovery house for specific dates.
Time off with slack
If your employer allows it, request a little more leave than the minimum. The same goes for a companion travelling with you.
Money: read the deposit terms before you pay
The financial pain of a postponement depends almost entirely on the terms you agreed to in advance. Before paying any deposit, ask the clinic in writing:
Deposit and postponement questions
- If my surgery is postponed for medical reasons after I arrive, is my deposit held for a new date, refunded, or lost?
- If the surgeon or clinic postpones for their own reasons, what do you cover?
- Are pre-operative tests and consultations charged separately if surgery does not go ahead?
- How long can a new date be scheduled, and does the price change?
Get the answers in writing. NHS guidance warns against handing over money for a surgeon or hospital you have never met, and encourages pinning down aftercare costs ahead of time. The same logic applies to postponement: clear terms on paper prevent disputes later. Our guide to paying for surgery in Medellín covers deposits more broadly.
If it happens to you
Hearing that your surgery is postponed can bring disappointment, frustration and even suspicion. A few steps help you respond well.
- Ask for the specific reason. Which result, finding or concern led to the decision? Ask for copies of any test results involved.
- Ask what needs to change. Is this a matter of days (repeat a test), weeks (stop a medication, recover from an illness) or longer?
- Ask whether the issue needs attention at home. A finding on pre-op tests may be worth following up with your own doctor regardless of surgery.
- Get the new plan and financial terms in writing before you rebook anything.
- Resist shopping for a "yes." If one surgical team has a safety concern, walking across town to find a clinic that will operate the next day does not make the concern go away.
When a postponement is a red flag about the clinic
Most medical postponements reflect careful practice. A few patterns, though, deserve a closer look:
- Repeated rescheduling for vague "clinic reasons" with no clear explanation.
- A sudden change of surgeon, facility or anesthesiologist offered as a way to keep your date.
- Pressure to pay more to proceed despite a stated safety concern.
- Refusal to give you copies of the results that led to the decision.
If you see these, it may be time to reconsider the clinic altogether. Our surgeon verification guide can help you start again on firmer ground.
The quiet upside
No one wants their surgery delayed. But a team willing to say "not today" when the results call for it is the same team that will take your concerns seriously after the operation. That is worth more than a date on the calendar.

Frequently asked questions
Why would a Medellín surgeon postpone my surgery after I arrive?
Common reasons include lab results outside the expected range, undisclosed medications or supplements, a positive nicotine test, a new illness such as a respiratory infection, or findings at the in-person exam that change the plan. Most are about safety.
How can I reduce the chance my surgery is postponed?
Ask for the full pre-op test list early, consider testing at home first if your surgeon agrees, disclose all medications and nicotine use honestly, speak with your own doctor before travel and protect your health in the days before flying.
Will I lose my deposit if surgery is postponed for medical reasons?
It depends on the clinic's terms. Ask in writing before paying whether a deposit is held, refunded or forfeited if surgery is postponed for medical reasons, and what happens if the clinic postpones.
Should I find another clinic that will operate if mine postpones?
Shopping for a quicker yes does not remove the safety concern that led to the delay. Ask for the specific reason and results, and if you want a second opinion, look for a verified surgeon who will review the same information.
How many days before surgery should I arrive in Medellín?
Ask your surgeon how many days they need for the in-person consultation and pre-op tests, then consider adding a buffer so a repeated test or minor issue does not derail the whole trip.
