Gastric sleeve in Cairo: how it works, risks, recovery and results

The surgeon removes about 80% of the stomach along its outer curve, leaving a banana-shaped tube (ASMBS). The smaller stomach fills quickly on small portions and produces less of the hormone that triggers hunger (Cleveland Clinic).

Unlike a bypass, the intestine is not rerouted, so food passes through the normal route. The ASMBS describes the sleeve as technically simpler, with a shorter operating time, and notes that it can be done in some high-risk patients (ASMBS). The price of that simplicity is permanence: the removed stomach cannot be put back, so the operation cannot be reversed (NIDDK).

The sleeve is generally considered for class III obesity, meaning a BMI of 40 or more, or at least 35 with a related disease, in people who have tried to lose weight without lasting success (Cleveland Clinic). International guidelines now recommend surgery from a BMI of 35 regardless of other conditions, and suggest considering it from 30 to 34.9 with metabolic disease (ASMBS/IFSO). You can check your number with our BMI calculator.

It may be the wrong choice if you already have troublesome acid reflux, because a sleeve can worsen it or cause new heartburn, while a bypass often improves it (ASMBS). It is also not a good idea if you cannot commit to lifelong supplements and follow-up, or have not yet tried non-surgical methods (NIDDK). Before any decision, the team assesses your physical health, mental wellbeing and eating patterns (NHS).

Sleeve gastrectomy is done under general anaesthetic, so you are asleep throughout (NHS). Most operations are laparoscopic, through small cuts rather than one large incision (Cleveland Clinic).

1. The surgeon makes a small cut of about 1.25 cm in the abdomen to insert a port, then one to three more small cuts for the instruments (Cleveland Clinic).
2. The abdomen is gently inflated and a camera shows the inside on a screen.
3. A sizing tube is placed in the stomach to guide the shape of the new sleeve.
4. A stapler divides the stomach along its length, and the larger outer part is removed through one of the small cuts.
5. The staple line is checked, the instruments are removed and the cuts are closed.

The operation usually takes 1 to 3 hours (NHS), and most people stay in hospital for one to two days afterwards (Cleveland Clinic).

Preparation starts with a full assessment: blood and urine tests, X-rays and scans to look for problems such as blood clots, ulcers and hernias (NHS). The team also talks with you about your eating habits, past attempts at weight loss and how you will cope with the changes after surgery (NHS).

Many programmes ask for a two-week liquid diet before the operation (Cleveland Clinic). Bring a list of all your medicines, including blood thinners and diabetes treatment, so the team can tell you what to stop or adjust.

Most people leave hospital one to three days after weight-loss surgery and begin returning to their normal activities after four to six weeks (NHS).

Food is reintroduced in diet stages, roughly as follows, although your own plan may differ (NHS):

Eat slowly, chew well and keep portions small. You will need vitamin and mineral supplements for life and regular check-ups, usually at the surgical clinic for at least the first two years and then once a year (NHS). Women are advised to avoid pregnancy for 12 to 18 months, until weight has stabilised (NHS).

Major complications after a sleeve occur in less than 1% of operations (Cleveland Clinic), and the risk of dying around the time of bariatric surgery is between 0.03% and 0.2% (ASMBS/IFSO).

• Staple-line leak: food or fluid can leak from the stomach and cause a serious infection that needs antibiotics (NHS).
• Bleeding, wound infection and reactions to the anaesthetic (Cleveland Clinic).
• Blood clots in the leg (deep vein thrombosis) that can travel to the lungs (NHS).
• Narrowing of the sleeve from scar tissue, causing nausea, vomiting and difficulty eating (Cleveland Clinic).
• New or worse reflux (ASMBS), which can often be treated with medication (Cleveland Clinic).
• Gallstones, especially with fast weight loss, and nutritional deficiencies (NHS, Cleveland Clinic).
• Loose folds of skin as the weight comes off (NHS).

Go to the nearest emergency department straight away, then call the surgical team, if you have any of the following (NHS):

• Difficulty breathing or chest pain, especially with pain and swelling in a leg
• Severe pain in the abdomen
• Vomiting blood, or vomit that looks like coffee grounds
• Heavy or non-stop bleeding from the back passage

Call the team the same day if you have a high temperature or shivering, a fast heartbeat or fast breathing, tummy pain or difficulty swallowing, repeated vomiting, or a red, swollen and painful leg (NHS).

The average weight loss after a sleeve is 25% to 30% of body weight in the first one to two years, and that average holds at five years (Cleveland Clinic). Across bariatric surgery, the durability of weight loss has been shown at 5, 10 and 20 years in several studies (ASMBS/IFSO).

Your own result depends heavily on what you eat and how active you are after the operation (NIDDK). The sleeve also has a smaller effect on metabolism than bypass operations (ASMBS), which matters if type 2 diabetes is a main reason for surgery.

The sleeve is one of several options, and the right comparison depends on your reflux, diabetes and BMI. A mini gastric bypass joins a narrow stomach to the small intestine with one connection (Cleveland Clinic). A classic Roux-en-Y bypass often improves reflux (ASMBS), and a balloon avoids surgery altogether.

The price depends on the hospital class, the surgical and anaesthetic team, the stapler cartridges used, the nights in hospital, the tests before surgery, and the dietitian and follow-up visits afterwards. Our page on gastric sleeve cost explains each item and what a written quote should include.
