Questions to Ask Before Bariatric Surgery
Twenty questions for consultations with a bariatric surgeon and programme team, covering the choice between procedures, centre and surgeon volume, what recovery and eating look like, lifelong supplements, medication changes, costs, and long-term follow-up. Written for patients and the family members who will be at home with them.
The questions
Open any question for the note
Which procedure are you recommending for me, and what in my history led you to it?
Why ask it
The recommendation should rest on specifics: your BMI, diabetes, reflux, previous abdominal surgery, medications you cannot stop. If the answer is mainly about what the centre does most often, that is worth knowing, and it is a reason to seek a second opinion rather than an objection to the surgeon.
How would a sleeve gastrectomy and a gastric bypass differ for someone with my medical history, including reflux?
Why ask it
The two operations have different trade-offs, and reflux is one of the clearest: sleeve gastrectomy can worsen it, while bypass is often chosen when reflux is already a problem. Asking for the comparison rather than the recommendation lets you hear the reasoning instead of the conclusion.
How many of these operations do you do each year, and what are your leak and readmission rates?
Why ask it
Surgeon and centre volume are associated with outcomes in bariatric surgery, and these figures are routinely tracked. You are listening for actual numbers and for how the surgeon responds to being asked, which is itself informative.
Is this hospital accredited for bariatric surgery, and who would I reach at two in the morning if something went wrong?
Why ask it
Accreditation means the hospital has staff, equipment and pathways set up for these patients. Ask specifically what happens out of hours, whether you go to this hospital or your local emergency department, and what you should tell staff there who may not know the anatomy of your operation.
What weight loss is typical at one, two and five years after this operation, and how much do people regain?
Why ask it
Most weight is lost in the first year to eighteen months, and some regain afterward is normal rather than a failure. Ask for the range the centre sees rather than the best case, and ask what proportion of their patients they are still able to follow at five years, because that number shapes how much any figure is worth.
How likely is a second operation later, and what would it be for?
Why ask it
Revisions happen for reflux, inadequate weight loss, regain, strictures and hernias, and the reasons differ by procedure. Knowing the common route from your operation to the next one is part of choosing between them, particularly if you are young.
What are the risks in the first thirty days, and which symptoms should make me call you straight away?
Why ask it
You need a plain list to take home: leak, bleeding, blood clot, obstruction, infection. More importantly you need the warning signs, since a rapid heart rate, worsening pain, breathlessness or an inability to keep fluids down can be the first indication of a problem that needs same-day assessment.
What will I be able to eat at one week, one month and six months?
Why ask it
The staged progression from liquids to pureed food to solids is more restrictive than most people picture, and portions stay small permanently. Ask for the written plan in advance so you can see whether the first weeks are workable alongside your job and household.
Which vitamins and minerals will I need for life, at what doses, and how will my levels be monitored?
Why ask it
Deficiencies in B12, iron, calcium, vitamin D and thiamine are well recognised after these operations, and some cause permanent harm if missed. Ask which blood tests are checked and how often, who orders them once you are discharged from the programme, and what the supplements will cost each month.
How will my current medications change, particularly for diabetes and blood pressure?
Why ask it
Doses often need reducing quickly after surgery, sometimes within days for insulin and blood pressure medicines. Extended-release tablets may need switching to other forms because absorption changes. Ask who adjusts these: the surgical team, your own doctor, or an endocrinologist.
Can I take ibuprofen or similar anti-inflammatory medicines afterwards?
Why ask it
After gastric bypass, these are usually avoided long term because of the risk of ulcers at the join. If you rely on them for arthritis, back pain or migraine, raise it now, since it can genuinely influence which operation is appropriate for you.
What changes about alcohol after this operation?
Why ask it
Alcohol is absorbed faster and felt more strongly after some procedures, and there is a recognised increase in alcohol-related problems in the years following bariatric surgery. This is a question to ask plainly and answer honestly to yourself, not only to the surgeon.
What is dumping syndrome, and how likely is it with the procedure you're recommending?
Why ask it
Rapid emptying of food into the intestine can cause cramping, nausea, sweating, palpitations and diarrhoea, and it is more common after bypass. It is manageable through what and how you eat, so ask which foods trigger it and what to do when it happens.
If I might want to become pregnant, how long should I wait, and what changes about the pregnancy?
Why ask it
Programmes generally advise waiting through the period of rapid weight loss, commonly twelve to eighteen months, and note that fertility can increase soon after surgery. Ask about contraception during that window and about the extra monitoring of nutrition in a later pregnancy.
How does your programme handle gallstones, hair loss and loose skin?
Why ask it
All three are common consequences of rapid weight loss. Gallstones sometimes require a further operation, hair thinning usually settles within a year, and skin removal is typically treated as cosmetic and not covered, which surprises people badly. Ask what your programme does about each.
What do I need to complete before this is approved and scheduled?
Why ask it
Requirements often include a supervised diet over several months, psychological assessment, stopping smoking, an endoscopy, sleep study, or a target amount of pre-operative weight loss. Get the list in writing with dates, since one missing item can delay a date by months.
What will this cost me in total, including the pre-op programme, supplements and follow-up?
Why ask it
The operation is one line among several. Ask about the pre-operative appointments, the dietitian, monthly supplements, repeat blood tests, and what happens financially if you need a revision or treatment for a complication. Ask what is not covered as well as what is.
What does follow-up look like at year two and year five, and who is responsible for it?
Why ask it
Long-term results depend heavily on staying in contact with a team, and many patients drift out of follow-up within a couple of years. Ask how appointments are scheduled that far out, whether your own doctor takes over, and who monitors the blood tests when the programme ends.
What support is there for eating behaviour and mental health, before and after?
Why ask it
Surgery changes the stomach and not the reasons people eat. Ask whether the programme includes a psychologist or dietitian with experience in this area, whether there is a support group, and what happens if binge eating or low mood appears six months after the operation.
What would make you advise me not to have this operation?
Why ask it
A considered answer will exist: an untreated eating disorder, current alcohol or drug dependence, unmanaged depression, an inability to attend follow-up, or another medical problem that should be addressed first. A surgeon who cannot name anything is not describing a careful assessment process.
Preparing for the consultation and the year after
Practical guidance for the conversation itself
Take someone with you, and take notes
These appointments cover a great deal quickly, and most people retain very little afterward. Bring the person who will be cooking, driving and noticing if you are unwell in the first weeks. Ask whether you can record the conversation, or write down the answers as they are given and read them back. Ask for the written diet plan, the supplement list and the follow-up schedule before you leave, since those three documents answer most of the questions that come up later at home.
Numbers and details worth writing down
- The exact name of the procedure planned, and whether anything else is being repaired at the same time, such as a hernia.
- The surgeon's annual volume for this operation, and the centre's leak and readmission figures.
- Expected nights in hospital, and how long before returning to work in your particular job.
- The supplement regimen with doses, and the blood tests due at three, six and twelve months.
- Which of your current medications change, and who is making that change.
- The out-of-hours contact number, and which hospital to attend if you become unwell.
- Total expected cost to you, including supplements and follow-up over the first two years.
Use the waiting period rather than enduring it
- The supervised programme before surgery is also a rehearsal. Practise the protein targets, small portions, and not drinking with meals now.
- Stopping smoking is usually required and reduces complications; ask for help with it rather than managing alone.
- Ask the dietitian what to buy before the operation, since shopping in the first fortnight is difficult.
- Sort out time off work, help at home, and childcare in advance, using the recovery timeline you were given rather than an optimistic guess.
- Attend a support group before surgery if one is available. Talking to people two years out is the most reliable way to hear what long-term life is actually like.
Where things tend to go wrong later
- Supplements stopped once someone feels well. This is the most common avoidable harm after these operations and can cause lasting damage.
- Follow-up appointments quietly lapsing, so that regain or a deficiency is found late.
- Grazing through the day, which is easier than eating meals and is the usual route to gradual regain.
- Alcohol increasing after surgery, often without the person noticing the change in how it affects them.
- Pregnancy during the period of rapid weight loss, before nutrition has stabilised.
- Assuming any abdominal pain months or years later is ordinary. Obstructions and internal hernias can present late and need assessment by a team that knows your anatomy.
On second opinions
Unless there is a pressing medical reason to proceed quickly, there is usually time to see another surgeon, ideally at a high volume accredited centre. A second opinion is most useful when you have a specific question: whether a different procedure suits your reflux or your medications, or whether a revision is a reasonable option. Bring your imaging, your endoscopy report and your list of medications so the second team can comment on your case rather than on generalities.
