Key takeaways
- Bariatric booking starts weeks before travel with labs, clearances and often nutrition and psychology screening.
- The 2022 ASMBS/IFSO guidelines let surgery be considered from a BMI over 35, or over 30 with metabolic disease; surgeons still decide case by case.
- Wait for a written, confirmed surgery date before buying travel you can't change.
- Lodging with a kitchen, elevator and nearby pharmacy matters more than location during the liquid-diet stage.
- Arrange home follow-up before surgery: nutritional monitoring continues for years.
Booking bariatric surgery in Colombia takes longer than booking most procedures, because the work starts weeks before you fly. You'll usually go through a medical evaluation, labs, possibly an upper endoscopy, nutrition and psychology screening, and a pre-operative diet the team prescribes. Then comes the hospital stay, a stretch of early recovery in the city, and a follow-up plan at home that lasts for years.
This guide lays out that sequence so you can see what has to happen before you buy a flight, what to expect once you're in Colombia, and how to set up aftercare at home before you leave. It's about booking and logistics. Whether surgery is right for you is a decision to make with a licensed physician who knows your history.
First, the eligibility conversation
Bariatric programs decide eligibility based on body mass index, related health conditions, your history with other weight-loss approaches, and your overall surgical risk. In 2022, the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) published updated guidelines that replaced the 1991 criteria many people still quote.
Under those guidelines, surgery may be considered for people with a BMI over 35 regardless of related conditions, and for people with a BMI over 30 who have metabolic disease or haven't achieved lasting weight loss by other means. The guidelines also say BMI thresholds should be adjusted lower for people of Asian descent. These are criteria for being considered, not automatic approval, and individual surgeons and hospitals apply their own judgment.
If you're taking a GLP-1 medication such as semaglutide or tirzepatide, tell the bariatric team early. These drugs can matter for anesthesia planning. Our guide to GLP-1 medications before surgery in Colombia covers the questions to raise. Don't stop or change a prescription on your own.
The pre-op timeline, before you fly
Every program sets its own sequence, and your health history may add steps. The outline below is a common shape, not a rule. Ask the program for its written pre-op list and timeline as soon as you start talking with them.
- Remote intake. You send your medical history, current medications, weight history, prior surgeries, and any recent labs or reports. The team reviews them and tells you what else they need.
- Initial consultation. Often by video. The surgeon discusses which procedure they'd consider for you, typically sleeve gastrectomy or gastric bypass, and why.
- Labs and testing. Bloodwork, and for many patients additional tests based on age and history, such as a cardiac evaluation or sleep apnea screening. Some can be done at home; some programs prefer to repeat them in Colombia.
- Specialist clearances. Depending on your history, the team may want letters from your cardiologist, pulmonologist, endocrinologist or primary care doctor.
- Nutrition and psychology evaluation. Many programs include these as standard, either remotely or on arrival.
- Pre-operative diet. Many programs prescribe a specific diet for a period before surgery. Follow the version your team gives you, and ask your home doctor to review it if you have diabetes or take medications affected by diet.
- Final scheduling. Once clearances are in, the program confirms your surgery date and you book flights.
Our article on pre-op labs and clearance for surgery in Colombia explains how to get home-country results into a format a Colombian team can use.
Upper endoscopy
Some bariatric programs request an upper endoscopy before surgery to look at the esophagus and stomach; others decide case by case. Ask whether your program requires one, whether they'll accept one done at home and how recent it needs to be, or whether they'll do it in Colombia. If it's done on arrival, it can add days to your trip, and results can occasionally change the surgical plan.
A clearance letter that comes back with a concern, or a test that needs repeating, can move your date. Wait until the program has confirmed your surgery date in writing, based on completed clearances, before locking in travel you can't change.
How long to plan to stay
Total trip length depends on the procedure, your health, the program's protocol, and your flight. Ask the program three separate questions: how many nights in the hospital they expect, how many days after discharge they want you nearby, and when they'd typically be comfortable with you flying home.
| Phase | What happens | What to confirm |
|---|---|---|
| Pre-op days in Colombia | In-person consult, any repeated labs, anesthesia review, possibly endoscopy | Which tests are done here, and how many days they need |
| Hospital stay | Surgery, monitoring, first liquids, walking | Expected nights, and what extends a stay |
| Early recovery in the city | Liquid diet progression, walking, follow-up visit | How many days nearby, and when the follow-up is |
| Fit to fly | Surgeon clears you for the trip home | Written clearance and clot-prevention advice for the flight |
The ASMBS notes in its patient guidance on medical tourism that long trips after surgery can raise the risk of blood clots. Ask your surgeon what they recommend for the flight home, and read our guide to the fit-to-fly letter so you know what to request before discharge.
Lodging, food and a companion
After bariatric surgery, your diet changes in stages, and the early stages are mostly liquids. That makes your lodging choice practical rather than scenic. You want a kitchen or kitchenette, a refrigerator, a blender if your plan includes blended foods, and a short, simple ride to the hospital.
- Elevator access or a ground-floor unit, since you'll be walking but not climbing much.
- A kitchen where you can measure and prepare what your dietitian prescribes.
- A nearby pharmacy for anything prescribed at discharge.
- Space to walk, such as a corridor, a building gym or a flat nearby park. Teams commonly encourage early walking.
- A companion, at least for the hospital stay and the first days out, if you can arrange one.
A companion can handle groceries, pharmacy runs and taxis while you focus on fluids and walking. Our guide to coordinating a caregiver or companion in Colombia covers how to split those roles.
Grocery delivery apps are widely used in Medellín and Bogotá, which helps when you need specific broths, protein products or electrolyte drinks during the liquid stage. Ask your dietitian for the exact products or types they want, and photograph the labels so you can match them locally.
Set up your follow-up at home before you leave
This is the part people most often skip, and it's the one that matters longest. Bariatric surgery changes how your body absorbs nutrients, so follow-up continues for years, typically including lab checks for nutritional deficiencies, vitamin and mineral supplementation as prescribed, diet guidance, and support for the psychological side of rapid change.
The ASMBS recommends that people traveling abroad for bariatric surgery arrange a post-operative plan with a qualified local bariatric program before surgery, and confirm whether insurance will cover follow-up and treatment of complications. It also notes that legal recourse for problems abroad can be difficult or impossible.
Questions for your home side
- Will my primary care doctor manage routine labs and supplementation, or should I be seen by a bariatric program at home?
- If a bariatric program at home is willing to follow me, what records do they want from Colombia?
- Does my insurance cover follow-up visits and the treatment of complications after surgery done abroad?
- Who do I call at home if I have an urgent problem in the first weeks back?
Questions for the Colombian team
- What does your follow-up include after I go home, and for how long?
- Can I share my home labs with you, and will you comment on them?
- Will you give me a full operative report and discharge summary in English?
- Who is my contact if something goes wrong after I've flown home?
Our article on coordinating a US doctor with a Colombia medical team explains how to get both sides talking before your surgery date, not after a problem appears.
Real risks to discuss with your surgeon
Bariatric surgery is major abdominal surgery. Risks your surgeon should discuss with you include bleeding, infection, leaks at staple lines or connections, blood clots, reactions to anesthesia, nutritional deficiencies over the long term, and procedure-specific issues such as reflux after a sleeve or dumping syndrome and ulcers after a bypass. Weight regain is also possible, and long-term outcomes depend heavily on follow-up and lifestyle.
A good program will walk you through these honestly and explain how they apply to you. If you feel rushed past the risk conversation, treat that as a reason to slow down.
What the booking package should spell out
Before you pay a deposit, ask for a written summary of what's included and what isn't. You don't need to compare line by line against other quotes to get value from this; you just need to know what you're agreeing to.
- Which pre-op tests are included and which you arrange separately.
- Hospital nights included, and how extra nights are handled.
- Whether nutrition and psychology sessions are part of the plan.
- The follow-up schedule in Colombia and remotely after you leave.
- What happens, clinically and financially, if a complication requires readmission.
- Which records you'll receive and in which language.

Frequently asked questions
Do I need an endoscopy before bariatric surgery in Colombia?
It depends on the program and your history. Some require an upper endoscopy for everyone, others decide case by case. Ask whether they accept one done at home and how recent it must be, or whether they'll do it on arrival, which can add days to your trip.
How long will I be in the hospital?
That varies by procedure, your health and the hospital's protocol. Ask the program for its expected number of nights and what would extend a stay, and plan extra days in the city after discharge before you fly.
Who handles my follow-up after I go home?
Ideally you set that up before surgery. The ASMBS recommends arranging a post-operative plan with a qualified local bariatric program, plus confirming insurance coverage for follow-up and complications. Your Colombian team may also offer remote follow-up.
Can I fly home soon after bariatric surgery?
Only once your surgeon clears you. Long flights after surgery can raise the risk of blood clots, so ask what they recommend for the trip and request a written fit-to-fly letter before discharge.
