A gastric sleeve — sleeve gastrectomy — is laparoscopic surgery that turns the stomach into a narrow tube, so you feel full on less food. Most of the fundus is removed; the rest stays in one line. It is not a gastric bypass with a new join to the bowel, not a balloon that is later taken out, not endoscopic stitching (ESG), and not a diet you buy as a weekend. How much of the stomach is stapled belongs on the written plan, not in a slogan. Weight loss still depends on what you drink, chew and attend after you fly; a target kilogram is not sold at a fixed fee.

The written plan should identify the laparoscopic sleeve, operating surgeon and hospital, anaesthetic arrangements, pre-operative assessment and tests. The hospital’s critical-care arrangements should also be confirmed by the treating provider.

Surgeons usually consider adults whose BMI and medical history meet a bariatric threshold after blood tests and a surgical review — often when diet and tablets have not been enough — who can commit to vitamins and follow-up for years, and who accept that the stomach cannot be put back. Severe reflux, a previous gastric operation, or a need for more malabsorption can point to bypass instead. If you only need a temporary balloon, that is a different sitting. If the plan is stitches from inside the stomach with no staple line, ESG is the conversation.

The date is often postponed if an untreated ulcer, a clotting risk or a heart or lung finding makes theatre less safe, or if you cannot pause smoking when asked. Send height, weight, medicines and any recent endoscopy if you have one. Suitability is confirmed in Istanbul before anyone staples. A bypass conversion on the table, a balloon “while we are there”, or a hair transplant in the same week is not assumed.

The written plan should identify the operation, pre-operative examination and named blood tests, general anaesthetic, hospital admission and the swallow or staple-line review used to assess discharge.

A gastric bypass, balloon or ESG is a different procedure and requires its own assessment and written plan. If the anatomy does not allow a safe tube, the surgeon may stop rather than staple further; that is a clinical limit.

Plan a stay covering the in-person assessment, the operation, three hospital nights and six separate hotel nights in a private room, with a swallow or staple-line check before discharge. Flying on day three is not a target; the treating team sets discharge and fit-to-fly clearance, and may advise further hospital observation.

Theatre is under general anaesthetic and usually lasts about one to two hours. It is a hospital admission, not a clinic chair. Discharge is signed after the team is happy with the staple line and you can keep fluids down — it is not an advertising clock.

The first weeks are liquids, then purée, then soft food as written — not a restaurant menu because the sleeve is new. Walk as soon as you are asked; that is for clots, not for sport. Desk work is often possible after about a week if the surgeon agrees. Gym, fizzy drinks and large meals wait for the timetable on your discharge note. Vitamins are not optional. Dumping after sweet drinks can happen; it is a lesson, not a second package. Weight change is fastest in the first months and still individual; loose skin later is a different quote.

Red flags after you return — spreading pain, a temperature that persists, vomiting you cannot stop, black stool, breathlessness, or a wound that opens — mean a local clinician or A&E first, then your coordinator. Take the discharge note with you.

These notes answer questions people raise before they accept a written treatment plan. They describe what that plan should make clear. They are not a promise that any partner hospital uses a particular technique, device or payment arrangement. With your consent, an enquiry may be shared with an authorised healthcare partner.

Why am I a candidate for this weight-loss procedure, and how do other illnesses change the choice?

Diabetes, sleep apnoea, blood pressure, medicines, earlier treatment and whether long-term follow-up is realistic have to be written for the person. A sleeve, a bypass, a balloon and endoscopic sleeve gastroplasty are not the same assessment. ASMBS describes ESG as an endoscopic option for selected adults who have not lost enough weight with lifestyle measures and medication, who are not ready for surgery, or whose surgical risk is higher. In most of that data the primary range is a BMI of 30–40, and a case outside it needs a separate written reason. ESG does not produce the same weight or metabolic effect as a sleeve or a bypass. A balloon does not take the place of that surgical assessment. Source: ASMBS ESG FAQ.

How do reflux or a hiatal hernia change the choice of sleeve, bypass, ESG or balloon?

Marked reflux or a hiatal hernia does not pass through the same door for a sleeve as it does for a volume-restricting balloon or ESG. A sleeve can increase reflux. In severe reflux, a bypass is discussed separately. Reflux symptoms, and endoscopy if it is needed, should be written before a balloon or ESG is chosen. This is not a promise that every case of reflux will settle with a bypass.

How is a leak after a gastric sleeve recognised and treated urgently?

The NHS says a leak from the stomach can appear days or weeks after a sleeve or a bypass, can cause a serious infection inside the abdomen, and can need antibiotics. Fever, a fast pulse, abdominal pain, fast breathing and vomiting that does not stop are assessed the same day. The NHS asks for 999 or emergency care for breathlessness with a swollen leg, chest pain, or bleeding that will not stop. Antibiotics do not mean the leak has closed by itself. The written plan should say who provides the scan and the route to an endoscopic stent or another operation. Source: NHS weight-loss surgery complications.

How is endoscopic sleeve gastroplasty different from a surgical sleeve, for me?

ASMBS describes ESG as a volume procedure that preserves the fundus and slows emptying of the stomach. The same weight loss or metabolic effect as a sleeve or a bypass should not be expected. In the MERIT study, mean total body-weight loss at 12 months was 13.6%. Series have reported 15–17.5%. Sutures and anchors can make a later sleeve, bypass or duodenal switch harder and can raise its risk. ESG is not recommended as a procedure on its own, without nutrition support and long follow-up. Source: ASMBS ESG FAQ.

If an urgent problem or a nutritional deficiency appears after I go home, who follows it and how are the costs split?

The NHS asks for lifelong blood tests to look for vitamin deficiency, and for 999 or 111 when emergency symptoms appear. Blood tests, a dietitian visit, another endoscopy and a hospital stay should not be assumed to sit inside the original package after treatment abroad. Travel insurance usually does not cover surgical complications. Sources: NHS recovery after weight-loss surgery, NHS advice on cosmetic surgery abroad.

Why does hair loss happen after gastric sleeve, and is it permanent?

Temporary hair shedding can happen after sleeve surgery, often during a period of rapid weight loss. The physical stress of surgery and changes in intake may contribute; inadequate protein or a nutritional deficiency can also be relevant, so the cause should not be assumed from appearance alone. Hair thinning often improves, but its course varies and persistent or severe loss deserves review and appropriate blood testing. Follow the bariatric team’s nutrition and supplement plan rather than adding high-dose products yourself. Ask the team which tests are appropriate and whether your protein and micronutrient intake need checking. University Hospitals of Derby and Burton NHS describes hair loss as common and usually temporary while noting nutritional factors; Chelsea and Westminster Hospital NHS Foundation Trust also lists temporary thinning during rapid weight loss.

What should I do if my weight loss slows or plateaus after gastric sleeve?

A slower rate of loss, or a period when the scale changes little, does not by itself show that the sleeve has failed. Weight trajectories vary. If the change persists or concerns you, contact the bariatric team for a review of your weight trend, food and fluid intake, medicines, activity, symptoms and follow-up blood tests. The team can decide whether nutrition support, medication or further investigation is relevant; another procedure is not an automatic next step. Do not change prescribed medicines or restrict food sharply without clinical advice. The NIDDK notes that outcomes differ and some people regain weight over time, while the ASMBS statement describes individualised options for inadequate response or recurrence.

How much weight can I realistically lose after gastric sleeve?

There is no single amount that can be predicted for an individual. Weight loss varies by procedure and personal factors, and surgery cannot guarantee a particular result. Published averages describe groups rather than what one person will lose. Ask the bariatric team how it measures outcomes and what is realistic for your circumstances. The NIDDK says outcomes vary by procedure and no method is sure to produce and maintain weight loss.

Can I regain weight after gastric sleeve?

Yes, some people regain part of the weight they lost after bariatric surgery, while others maintain their loss; the amount varies. Regain alone does not explain why it happened or mean another operation is needed. A review can consider the longer-term weight trend, nutrition, medicines, activity and health changes. Ask the bariatric team to assess a sustained change rather than trying an extreme diet or changing medicines yourself. The NIDDK notes that regain occurs for some people and may depend on several factors.

Will I need vitamins for life after gastric sleeve?

Many bariatric programmes recommend long-term, often lifelong, vitamin and mineral supplements after sleeve surgery, together with regular blood tests. The exact supplements depend on your operation, diet and blood results, so follow the plan from your bariatric team rather than choosing products or doses yourself. Ask who will arrange prescriptions and testing after you return home. The Chelsea and Westminster NHS Foundation Trust describes lifelong supplements after sleeve surgery, while the NHS advises ongoing blood tests and follow-up.

When can I become pregnant after gastric sleeve?

General NHS guidance advises avoiding pregnancy for 12–18 months after weight-loss surgery, until weight has stabilised. This is not individual clearance to conceive: nutritional status, medicines and personal circumstances need review, and closer pregnancy monitoring may be needed. If you are planning a pregnancy, speak with the bariatric team and maternity clinician before trying, and ask for a plan for supplements and blood tests. The NHS gives the 12–18 month guidance and notes that fertility may increase after surgery.

What happens to loose skin after major weight loss?

After substantial weight loss, some people have folds of excess skin around the abdomen, breasts, hips or limbs; others have less. The amount cannot be predicted from a planned weight-loss figure. Skin removal is a separate decision after health and weight are assessed, and is not part of sleeve surgery or this guide price unless expressly itemised. If excess skin concerns you, discuss options and timing with an appropriately qualified clinician. The NHS explains that excess skin may remain after weight loss and that surgery may be used to remove it.
