Recovery After Sleeve Gastrectomy — Week-by-Week Timeline

Day of surgery (Day 0)

Most patients arrive in the morning, have surgery taking 60–90 minutes, and are recovering in their room by lunchtime. You will feel groggy from anaesthesia for the first 4-6 hours.

• Approximately 6 hours post-op: sips of clear water permitted, typically 30 mL every 15 minutes
• Mobilisation: the nursing team will help you sit up, then walk to the bathroom by evening. This is critical for preventing deep vein thrombosis.
• Pain control: intravenous analgesia in the immediate post-op period, transitioning to oral the next morning. Pain is typically much less than patients expect — most describe it as 4-5/10.
• Anti-thrombotic prophylaxis: low molecular weight heparin injection in the evening (this continues for 7-14 days post-discharge).

Day 1 — discharge for most patients

Discharge timing depends on the centre. At Dr Bansal Gastro & Liver Centre, most uncomplicated sleeve patients are discharged on Day 2 or 3. Day 1 typically includes:

• Drain removal (if one was placed)
• Transition to oral pain relief and oral PPI
• Continued mobilisation — at least 6-8 short walks per day
• Clear liquids: water, sugar-free electrolytes, thin clear soups, sugar-free jelly
• Discharge teaching: how to recognise warning signs, when to call, when your next review is scheduled

Week 1 — clear and full liquids

The most disciplined week. Your stomach has just had 75-80% removed and the staple line needs uninterrupted healing. Diet stays liquid.

• Allowed: water, sugar-free electrolyte drinks, clear broth, strained thin soups, sugar-free Jell-O, very dilute fresh juice (no pulp), milk and lassi (towards end of the week)
• Sip slowly — 30-60 mL at a time, every 15 minutes. Do not gulp. Do not drink while eating (later in recovery).
• Avoid: carbonated drinks (forever), straws (they introduce air), caffeine in excess
• Protein: aim for 40-60g protein/day from week 1 onwards — easier said than done at this stage. Use a high-quality protein supplement (whey isolate or pea-based) mixed with water or low-fat milk.
• Pain: rapidly improving by Day 5-7. Paracetamol is usually adequate.
• Activity: walk 15-20 minutes 3-4 times a day. No lifting more than 5kg. No driving until you're off opioid analgesia.

Week 2 — full liquids continued, dietitian review

Most patients have a scheduled review at 7-10 days post-op. The dietitian and surgical team will check your weight, hydration, protein intake, and how you're tolerating liquids.

• Diet remains liquid but can thicken — protein shakes, yogurt, custard, strained dal, blended vegetable soups
• Many patients return to desk-based work at this stage — fatigue is the main limiter, not pain
• Activity: longer walks, very light cardio. No abdominal exercises. No strength training.
• Supplements start: multivitamin (chewable or liquid), calcium, vitamin D

Weeks 3-4 — puréed foods

Transition to puréed (smooth, no chunks) foods. Think pre-blended baby-food-like texture. This is where many patients struggle psychologically — eating textureless food for two weeks tests resolve. It is non-negotiable for staple-line safety.

• Allowed: puréed dal, puréed chicken/fish with broth, puréed vegetables, mashed paneer, eggs scrambled very soft, thin oatmeal, ricotta cheese
• Portion size: 60-90 mL per meal, 4-5 meals per day. Stop the moment you feel full — your sleeve is small and gets uncomfortable quickly.
• Protein remains the priority: 60-80g/day
• Hydration: 2 litres per day, sipped between meals (not during)
• Activity: resume light gym (cardio, walking, light cycling). Still no abdominal exercise.

Weeks 5-6 — soft foods

Most patients begin to feel "normal" again here. Soft solid foods can be added — slowly chewed, slowly swallowed.

• Allowed: well-cooked dal, soft cooked rice, soft chapati (small pieces), boiled vegetables, soft chicken, soft fish, paneer, yogurt
• Chew thoroughly — every mouthful at least 20-30 times. Eating too fast is the most common cause of pain, nausea, and vomiting at this stage.
• Avoid: raw vegetables, fibrous meats, fried foods, bread (forms a sticky bolus), red meat, anything spicy in the first few weeks
• Activity: resume full cardio. Light strength training. No heavy lifting until 8 weeks.

Month 2-3 — return to regular textures

Gradual reintroduction of regular textures. Weight loss is typically rapid in these months — 6-10 kg per month is normal.

• Allowed: most regular foods at sleeve-sized portions (typically 150-200 mL per meal)
• Continue to chew thoroughly, eat slowly, separate liquids from solids
• Avoid: sugary foods (cause dumping in some patients), large meals, eating too fast
• Activity: full activity including strength training. No restriction.
• Scheduled review: 6 weeks and 3 months post-op with the surgical and bariatric team

Month 6-12 — stabilisation

The honeymoon period of weight loss continues but slows. Most patients lose 60-70% of their excess weight by month 12.

• Eating pattern: small meals 4-5 times daily becomes the new normal
• Hunger: begins to return at around 6-9 months as the ghrelin effect dampens — this is the time when discipline matters
• Annual blood work: iron, vitamin B12, vitamin D, calcium, folate, protein
• Lifelong supplements continue: multivitamin, calcium, vitamin D
• Long-term reviews: 6 months, 12 months, then annually

When to call your surgeon — red flags

• Persistent fever above 38°C / 100.4°F — may indicate a leak or infection
• Severe, increasing abdominal pain — particularly if associated with rapid heart rate or shortness of breath
• Tachycardia at rest (heart rate above 120 bpm) without fever — this can be the only sign of a staple-line leak in the first 1-2 weeks
• Persistent vomiting that you cannot keep liquids down for more than 12 hours
• Inability to drink fluids for more than 6 hours
• Calf pain, swelling, or shortness of breath — possible deep vein thrombosis or pulmonary embolism
• Blood in vomit or black tarry stools — possible staple-line bleed
• Wound redness, swelling, discharge, or increasing pain — port-site infection

The most serious complication of sleeve gastrectomy — a staple-line leak — typically presents in the first 5-14 days with tachycardia, fever, and abdominal pain. Early recognition saves lives. Patients of Dr Bansal Gastro & Liver Centre have a direct line to the surgical team for any concern. Do not wait. Do not "see how it goes overnight."

Lifelong supplementation

After sleeve gastrectomy, intake is too small to meet micronutrient requirements through diet alone. Lifelong supplementation is part of the bariatric agreement, not optional. Standard regimens include:

• Multivitamin with iron (often bariatric-specific formulations)
• Calcium citrate — 1200-1500 mg/day in divided doses
• Vitamin D3 — typically 2000-3000 IU/day, adjusted based on blood levels
• Vitamin B12 — sublingual or intramuscular based on annual levels
• Iron — separately if iron deficiency develops, especially in menstruating women

Annual blood work tracks deficiencies before they cause symptoms. Skipping supplementation is the most common reason for long-term complications after sleeve gastrectomy — and it's entirely preventable.
