When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the key measure used to assess how severe obesity is. You get it by dividing body weight (kg) by height squared (m²). Surgery is generally justified at a BMI above 40, or above 35 when serious related conditions are present. Sometimes it is also considered at lower values — when non-surgical methods have not worked.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Unsuccessful past attempts at weight loss by traditional means
Why don't diets and exercise work for everyone?
People often spend years on diets and physical activity, but the body counters: metabolism slows, appetite increases, lost weight creeps back. When it is plain that changing the diet and taking medication cannot fundamentally improve things alone, bariatric surgery is the only effective exit.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
The surgeon takes out most of the stomach and shapes the rest into a narrow tube. Portion size shrinks sharply and ghrelin, the hunger hormone, drops, so fullness comes much faster and the patient eats less.
Effectiveness: the method is used for a BMI of 35 to 45; average loss is 60–70% of excess weight.
Specifics: the result holds up less well than after bypass operations. If the diet is broken, particularly with high-calorie drinks and liquid food, weight may come back.
Roux-en-Y gastric bypass
At the top of the stomach the surgeon makes a small 50–70 ml pouch, linking it directly to the small intestine. Intake of food is restricted and calorie absorption falls, since food passes through less of the gut.
Effectiveness: known as the “gold standard” for a BMI over 45–50 combined with type 2 diabetes. Excess weight loss hits 75–85%.
Specifics: the result lasts better than with other bariatric methods. Related conditions such as diabetes and hypertension often go into remission. Because the digestive anatomy changes, lifelong vitamin and mineral supplements are needed.
Mini gastric bypass (MGB)
A modified version of the classic bypass. Unlike the standard operation, just one connection (anastomosis) joins the small stomach and the small intestine. The technique is simpler, so it is easier on the patient and recovery takes less time.
Effectiveness: in line with the classic Roux-en-Y bypass — loss of 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)
SADI-S is a modern combined method that brings together the advantages of sleeve gastrectomy and intestinal bypass. It is performed in two stages: first the stomach becomes a narrow tube, then the small intestine is rerouted so most of it no longer takes part in active digestion.
Effectiveness: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
Specifics: removing the ghrelin-producing zone makes the stomach smaller and lowers appetite, while rerouting food around part of the intestine restricts calorie absorption. Indicated for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

Support that stays in touch
After surgery, the team at City Medical Centre stays with you. For the entire first year, specialists keep track of your weight loss, oversee your tests and answer all questions about diet and recovery.
Fast recovery

Full diagnostics on site
You won't need to visit several clinics. Our centre covers the whole work-up, from our in-house lab to ultrasound and gastroscopy. Quick preparation with no queues, all in one building.
Recovery after bariatric surgery
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.
Duration
The patient is kept under clinic observation for 1 to 5 days, depending on the scale 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
7–14 days after surgery you can return to work, depending on how physical the job is.
Restrictions
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
A staged diet is set for 1–2 months — from liquid to solid food — so the stomach can adapt.
Pace
Patients who follow what specialists advise lose 10% of excess weight per month on average.
Stabilization
The final outcome arrives within 1.5–2 years. By this time the patient has lasting eating habits that stop the weight returning.
Important! Recovery is overseen by City Medical Centre specialists, with psychological and medical support at every step of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often confused, yet their goals differ fundamentally. Bariatric surgery is a medical treatment for obesity and its related diseases. It alters how the digestive tract works, tackling the causes of excess weight and metabolism. Plastic surgery changes the body's outer contours; it neither treats obesity nor affects metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.
What diet do I need to follow?
Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing high-calorie, fatty food.
What types of bariatric surgery are there?
Four main types of bariatric surgery are performed at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each is selected individually based on BMI, related conditions and patient goals.
Can I plan a pregnancy after surgery?
Pregnancy is possible after bariatric surgery; doctors advise waiting no less than 12–18 months. This gives the body time to stabilize, for weight to reach target values and nutritional status to normalize.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins are a must. The altered digestive anatomy reduces absorption of some nutrients, which makes regular vitamin and mineral supplements a permanent part of the patient's life.
Can the weight come back?
Weight regain after bariatric surgery is possible, but very unlikely if you follow the doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

Bariatric surgery in Mexico City: what you should know

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 Mexico City.
Starting is simple. Leave your name and phone number or write in any messenger, and a coordinator will arrange a free consultation.
