Medical Clearance Before a Colombia Booking: What Can Delay or Cancel Treatment

What "clearance" actually means

For surgery, sedation or other higher-risk treatment, the treating team usually wants evidence that your health supports the plan. That evidence might include blood tests, an ECG, imaging, a letter from a specialist who manages one of your conditions, or an anaesthesia assessment. Different procedures and clinics ask for different things, so the first step is always to get the clinic's list in writing.

Clearance answers a clinical question, not an administrative one. A test that comes back abnormal is not something to get around by retesting somewhere else. It is information that may change whether, when or where the procedure should happen.

Questions to ask before you book

• Which tests and documents are required for my case? Get the list specific to you, not a generic form.
• How recent must each one be? Results that are too old may have to be repeated.
• Where can they be done? At home, in Colombia before the procedure, or either.
• Who reviews them, and when? Is it the surgeon, an anaesthesiologist or an internist, and is the review before you travel or after you arrive?
• What results would postpone treatment? Ask for the most common reasons this clinic delays a procedure like yours.
• What happens to the deposit if clearance fails? See cancellation and rescheduling policies to check.

Testing at home versus in Colombia

Many patients do both: the key tests at home to catch problems early, and the clinic's own pre-op checks after arrival. If you have a chronic condition, testing early at home is usually the safer order.

What commonly delays treatment

These are broad categories to raise with the clinic, not a diagnostic list. Whether any of them affects your case is a decision for your clinicians.

Medications you didn't mention

Blood thinners, diabetes medicines, steroids, supplements and weight-loss drugs can all affect surgery or anaesthesia. The CDC Yellow Book (2026) tells patients going abroad to give the overseas team their complete medical, surgical and travel history. Bring an exact list with doses, and don't stop or change anything without guidance from the prescriber and the treating team.

GLP-1 medications

If you take a GLP-1 receptor agonist (a class used for diabetes and weight management), tell the surgical team early. Multi-society guidance announced by the American Society of Anesthesiologists (2024) says most patients can keep taking these drugs before elective procedures. It singles out higher-risk groups: people in the dose-escalation phase, which typically lasts four to eight weeks; people with current nausea, vomiting, abdominal pain or constipation; and people on higher doses. For the highest-risk patients, it suggests a liquid-only diet for 24 hours before the procedure, and it says elective surgery may need to wait until escalation has passed and symptoms have settled. For a traveller, that can move your date by weeks, so raise it before choosing one.

Conditions that aren't well controlled

High blood pressure, blood sugar or other chronic problems that are out of range on the day can lead an anaesthesiologist to postpone. If your home doctor manages a condition, ask them for a short summary letter you can send ahead.

Recent illness, nicotine and pregnancy possibility

A recent respiratory infection, nicotine use the surgeon told you to stop, or a possible pregnancy can each change the plan. Be honest in the intake. A postponement in Colombia is disruptive, but a complication is worse.

Travel-related clot risk

The flight itself is part of the clinical picture. The CDC (2024) says travel of more than four hours can raise the risk of blood clots. The risk climbs with other factors: surgery or injury in the past three months, age over 40, obesity, estrogen-containing birth control or hormone therapy, pregnancy, previous clots and active cancer, among others. If you have any of these, ask the treating team how they will manage clot risk around the procedure and the flights.

Prepare your clearance packet

Put the clearance documents in one place before the remote consultation. Our guide to the medical tourism records packet covers the full case file. For clearance specifically, include:

• A medication and supplement list with doses, including how often you take any injectable drugs.
• Recent lab results and ECG, with dates.
• Letters from specialists for any condition the clinic asked about.
• Any previous anaesthesia problems, yours or a close relative's.
• Allergies, including to latex, antibiotics and adhesives.

The U.S. State Department's health abroad guidance also recommends carrying a letter from your doctor that names each prescription by its generic name, and keeping medicines in the packaging they came in. That letter helps at the border, and it helps the Colombian team read your medication list correctly.

Give clearance enough lead time

Clearance usually takes longer than people expect, mostly because it depends on other people's calendars. A specialist letter needs an appointment. Results have to be sent, sometimes translated, and then reviewed. Questions from the Colombian team may mean another test. Work backwards from the treatment date.

1. At the first remote consultation: get the clearance list and the recency rules for each item.
2. Straight afterwards: book the home appointments and tests you need, starting with anything that needs a specialist.
3. When results arrive: send them to the clinic and ask for written confirmation that they were reviewed, and by whom.
4. If something is borderline: ask the treating team before you buy flights whether it changes the plan.
5. Before you fly: confirm in writing which checks are still to come after arrival.

Be aware that some results expire. If your date slips, tests done too early may need repeating.

Book travel as if clearance might say "not yet"

Until clearance is complete, use flights and lodging you can change. If a key test can only be done after arrival, ask the clinic how quickly results come back and what the plan is if one is abnormal: a short delay while you stay, or a trip home. Our guide to what to do if the treatment plan changes after arrival covers that situation.

A postponement after a clearance review can be disappointing and expensive. It is also often the clinical team doing its job. Plan your budget so that hearing "not yet" is something you can afford.

Frequently asked questions

Can I get my pre-op tests done at home instead of in Colombia?

Often, yes, but ask the clinic first which tests it will accept, how recent they must be and whether it will repeat any on arrival. Testing key items at home helps catch problems before you spend money on travel.

Do I have to stop my GLP-1 medication before surgery abroad?

Not necessarily. Multi-society guidance announced by the American Society of Anesthesiologists in 2024 says most patients can continue, with extra steps for higher-risk patients. Tell the surgical team and your prescriber early, and follow their instructions rather than stopping on your own.

What happens if a test comes back abnormal after I arrive?

The treating team may delay the procedure, order more tests or decide not to proceed. Ask before booking what the clinic usually does in that situation and how it affects your deposit and dates.

Does the flight affect whether I'm cleared?

It can. The CDC says travel of more than four hours can raise blood clot risk, especially with factors such as recent surgery, age over 40, obesity or hormone therapy. Ask the treating team how they will manage clot risk around the procedure and the flights.

Who decides if I'm cleared for treatment?

The treating clinical team, usually the surgeon or proceduralist together with an anaesthesiologist where sedation is involved. Coordinators can collect documents, but they can't clear you.
