Preparation for bariatric surgery
Atmosphere in the medical center

Preoperative evaluation (free in-person consultation)

Conducted before hospitalization. At the consultation we assess: indications and contraindications for surgery, medical history, comorbidities, current medications; if necessary, we order additional tests or consultations with other specialists. Surgery is not suitable for everyone - we inform the patient of our decision at the consultation; if there are contraindications, we discuss alternative treatment options.

Day 1 - Admission to hospital

Complete preoperative examination by the surgeon and anesthesiologist; collection of necessary tests (blood, urine, coagulation profile), ECG, and other tests if indicated; instructions on preoperative preparation and signing of informed consent.

Day 2 - Surgery day

Surgery under general anesthesia.

Days 3–5 - Inpatient monitoring (3 more days)

Monitoring of vital functions, pain control, early mobilization, gradual restoration of nutrition step by step; prevention of thromboembolism and infections. Discharge if stable and criteria for readiness are met (pain managed with oral medications, tolerance of prescribed diet/fluids, adequate mobility).

Follow-up and control tests

  • First visit: 2–3 weeks after discharge - evaluation of condition, adjustment of treatment if needed.
  • 3 months: patient completes recommended lab tests at their local laboratory and sends results to the clinic. If abnormalities are found - additional in-person consultation.
  • 6 months: repeat set of control lab tests and in-person clinic visit for progress evaluation and planning further follow-up.
  • Afterwards, monitoring schedule is tailored individually.

What to do in advance (do not delay)

  • Start a preoperative diet to reduce liver size - usually 1–2 weeks before admission.
  • Quit smoking - the earlier, the better; at least 4–6 weeks before if possible.
  • Stabilize comorbidities (diabetes, hypertension, etc.) - follow your cardiologist’s/endocrinologist’s prescriptions.
  • Coordinate stopping/adjusting medications (anticoagulants, antiplatelets, some antidiabetics, NSAIDs) - per doctor’s instructions.
  • Prepare documents/items: ID/insurance, list of medications, CPAP (if you use it), comfortable loose clothing for discharge.

On admission day (Day 1) - what to expect

  • Clinical examination by surgeon and anesthesiologist.
  • Collection of all required tests and studies.
  • Instructions on preoperative diet, hygiene (antiseptic shower), fasting times as directed by anesthesiologist.
  • Signing informed consent (if not yet signed).

On surgery day (Day 2) - what to expect

  • Meeting anesthesiologist before anesthesia.
  • Laparoscopic surgery (usually through 4–6 small incisions). Duration depends on the procedure, typically 1–3 hours.
  • Intraoperative antibiotic prophylaxis if needed and thrombosis prevention measures.
  • After surgery - transfer to ward/ICU for monitoring.

Inpatient monitoring (3 more days)

  • Early mobilization: start standing/walking as early as possible (same day or next).
  • Breathing exercises (incentive spirometer, deep breathing) - pneumonia prevention.
  • Pain management: multimodal approach (minimizing opioids).
  • Thromboembolism prevention: compression stockings/devices, low molecular weight heparin if indicated.
  • Diet progression: clear liquids → protein shakes → semi-liquid/pureed food. Goal - adequate protein and hydration.
  • Monitoring: temperature, heart rate, blood pressure; additional tests if condition worsens.
  • Discharge criteria: pain controlled with oral meds, tolerance of prescribed fluids/food, adequate mobility, stable vitals.

Post-discharge nutrition rules - see brochure:https://bariatr.com.ua/rek.pdf

Weekly diet progression (approximate)

  • Week 1 - clear liquids and protein shakes.
  • Weeks 2–3 - thick liquids/pureed food.
  • Weeks 4–5 - soft food (fish/meat mashed with fork) in pureed/soft consistency.
  • From weeks 5–6 - gradual introduction of solid foods (as tolerated).

Portion size: max ~150 ml food per meal. Drinks - small sips (~30 ml at a time).Frequency: small meals every 3–4 hours, no skipping.Protein: priority nutrient. Goal ~80–90 g/day (use protein shakes if needed).Fluids: sip frequently - total daily target 1.5–2 L.Food & drinks separation: wait at least 30 min between eating and drinking (do not “wash down” food).Forbidden: alcohol, carbonated/sweet drinks, sugary high-calorie liquids; no straws.Introducing foods: one new item per day, monitoring tolerance.

Medications & supplements

  • Multivitamins - lifelong.
  • B12, calcium (citrate) + vitamin D, iron - as indicated and guided by lab results; many patients require lifelong support.
  • If anticoagulants are prescribed after discharge - follow physician’s instructions.

Physical activity & work - what and when allowed

  • Walking: start immediately, aim to increase daily.
  • Return to office (sedentary) work: usually after 6–7 days if feeling well, with doctor’s approval.
  • Heavy physical work/lifting: avoid lifting >5–10 kg for 6–8 weeks (longer if advised).
  • Driving: not allowed while taking opioids or until reaction/reflexes are normal - usually minimum 1–2 weeks.

(Timelines are individual - final decision is made by your treating physician depending on condition.)

So glad I chose this clinic. After sleeve gastrectomy, I was constantly guided by doctors who patiently answered every question. Eight months have passed, and I am extremely happy with the results. Thank you for your care and help.
