Surgery is prescribed only when clear criteria are met
Obesity is graded mainly by BMI, calculated as body weight (kg) over height squared (m²). A BMI above 40 usually justifies surgery, as does a BMI above 35 with serious related conditions. In certain cases surgery is considered at lower values too, if approaches without surgery have not succeeded.
Many people try various diets and exercise for years, but the body fights back: metabolism slows, appetite grows and the lost weight returns. When it becomes clear that diet changes and medication alone cannot fundamentally improve the situation, bariatric surgery becomes the only effective way out.

Sleeve gastrectomy
In surgery, most of the stomach is taken out and the rest is formed into a narrow tube. Portions become far smaller and ghrelin, the hormone behind hunger, drops, so the patient feels full quicker and eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: the result is less durable than with bypass operations. If the diet is not followed, especially with high-calorie drinks and liquid food, the weight can return.

Roux-en-Y gastric bypass
A small pouch of 50–70 ml is created from the upper stomach and connected directly to the small intestine. Food intake is limited, and fewer calories are absorbed because food travels a shorter path through the gut.
Effectiveness: considered the “gold standard” when BMI exceeds 45–50 with type 2 diabetes. Patients lose 75–85% of excess weight.
Specifics: the effect lasts longer than with other bariatric methods. Related diseases, including diabetes and hypertension, often reach remission. As digestive anatomy changes, supplements of vitamins and minerals are needed for life.

Mini gastric bypass (MGB)
This procedure improves on the classic bypass. Instead of the standard approach, the surgeon creates a single connection (anastomosis) between the small stomach and the small intestine. A simpler technique means an easier experience for the patient and a shorter recovery.
Effectiveness: comparable to the classic Roux-en-Y bypass — patients lose up to 75–80% of excess weight.
Specifics: shorter surgery and faster recovery. The procedure is technically reversible, but there is a risk of bile reflux due to the single anastomosis.

Single anastomosis duodeno-ileal bypass (SADI-S)
As a modern combined technique, SADI-S brings together the benefits of sleeve gastrectomy and intestinal bypass. Its two stages: making the stomach into a narrow tube, then rerouting the small intestine so the majority of it is excluded from active digestion.
Effectiveness: one of the most powerful options in bariatric surgery: excess weight loss of 80–90%, lasting a long time.
Specifics: the reduced stomach lowers appetite once the ghrelin-producing zone is removed, and routing food past a section of intestine limits how many calories are absorbed. Suitable for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

At City Medical Centre obesity is treated with a comprehensive approach. Once examined, each patient receives a personal lab and instrumental diagnostic program aimed at finding every disorder in the body.

A method matched to your goal
Choosing the surgical method is individual for each patient at our clinic. Doctors first review your health, history of weight and related conditions and then propose the most suitable surgical option.

Support that stays in touch
The City Medical Centre team is with you after surgery too. For the full first year, specialists track weight loss, keep an eye on your tests and answer every diet and recovery question.

Fast recovery
City Medical Centre's bariatric operations are laparoscopic, so recovery is much shorter. On day one most patients are already up and moving, and within a week they return to normal life.

Full diagnostics on site
There is no need to rush between clinics. Our centre offers your entire work-up — our own lab, ultrasound, gastroscopy. Preparation goes quickly, with no queues, all in one building.
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.

Duration
The patient stays under observation at the clinic for 1 to 5 days, depending on the extent of surgery and related conditions.
Activity
Within the first hours after surgery you may sit up, stand and drink fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
Work can be resumed 7–14 days after surgery, depending on how physically demanding it is.
Restrictions
In the first weeks, avoid the bathhouse, sauna and intense physical exercise.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.

Pace
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
Stabilization
The end result is achieved in 1.5–2 years, when the patient already has stable eating habits that prevent weight regain.
Important! City Medical Centre specialists supervise your recovery and support you psychologically and medically at every stage of weight loss.

Bariatric vs plastic surgery: what's the difference?
It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.
What diet do I need to follow?
Diet changes happen in stages, from liquids to soft food and then solids. It centers on protein and limits high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre offers four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is chosen individually according to BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature of the patient's life.
Can the weight come back?
Weight may return after bariatric surgery, though that is very unlikely when you follow the doctor's advice. Key factors: proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.

Roux-en-Y gastric bypass creates a small 50–70 ml pouch at the top of the stomach and connects it straight to the small intestine. It is considered the gold standard for a BMI over 45–50 with type 2 diabetes, bringing excess weight loss of 75–85%. Anyone researching bypass in Lima should know that it requires lifelong vitamin and mineral supplements.
Preparation is practical. Two to four weeks before surgery, cut fast carbohydrates and fats; a month before, quit smoking, reduce physical activity and avoid stress. The day before, switch to light meals, with the last light meal in the evening and last fluids 3–4 hours before the operation. The same plan applies to everyone preparing for bariatric surgery in Lima.
