When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
The degree of obesity is mainly assessed with BMI: body weight (kg) divided by height squared (m²). As a rule, surgery is justified when BMI exceeds 40, or exceeds 35 alongside serious related conditions. In some cases lower values may also qualify for surgery if non-surgical approaches have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Weight-loss attempts using conventional methods have not succeeded
Why don't diets and exercise work for everyone?
Plenty of people diet and exercise for years, only for the body to resist: a slower metabolism, a bigger appetite and the weight coming back. When diet changes and medication clearly cannot fundamentally improve matters on their own, the only effective option left is bariatric surgery.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During the procedure the surgeon removes the greater part of the stomach, forming a narrow tube. Portions get far smaller and ghrelin, the hunger hormone, decreases, so the patient is satisfied faster and eats less.
Effectiveness: recommended for a BMI of 35 to 45. Typically patients shed 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
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: the operation is considered the “gold standard” for a BMI over 45–50 with type 2 diabetes. Excess weight loss reaches 75–85%.
Specifics: outcomes are more durable than with other bariatric procedures. Diabetes, hypertension and other related conditions often go into remission. With the digestive anatomy changed, lifelong vitamin and mineral supplements are a must.
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: comparable with the classic Roux-en-Y bypass: patients drop up to 75–80% of excess weight.
Specifics: shorter surgery, quicker recovery. It is technically reversible, yet bile reflux is a risk because of 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: counted among the most powerful bariatric operations — 80–90% excess weight loss with a durable result.
Specifics: the smaller stomach, minus its ghrelin-producing zone, dampens appetite, and bypassing a portion of the intestine limits calorie absorption. It is an option in super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre sees obesity comprehensively. From the first examination, each patient has a personal diagnostic program (lab and instrumental) built to identify every disorder present 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
City Medical Centre's team remains with you after surgery. Over the first year specialists watch your weight loss, monitor test results and respond to all questions regarding diet and recovery.
Fast recovery
City Medical Centre performs bariatric operations laparoscopically, which shortens recovery considerably. Most patients are on their feet on day one and back to normal life within a week.
Full diagnostics on site
You don't have to go clinic to clinic. Our centre has everything needed for your work-up — own lab, ultrasound, gastroscopy. Fast preparation, no queues, one building.
Recovery after bariatric surgery
Much of recovery depends on the individual, but minimally invasive laparoscopic techniques keep the rehab stage as short as possible.
Duration
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is and related conditions.
Activity
Sitting up, standing and drinking are allowed in the first hours after surgery.
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
During the first weeks, stay away from bathhouses, saunas and intense exercise.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
By following the specialists' advice, patients lose 10% of excess weight per month on average.
Stabilization
The final result is seen after 1.5–2 years. In that time the patient builds stable eating habits that keep the weight from returning.
Important! Your recovery is supervised by City Medical Centre specialists, who give psychological and medical support through each stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Though often confused, the two have fundamentally different goals. Bariatric surgery is a medical treatment of obesity and related illnesses; it changes the functioning of the digestive tract to address the causes of excess weight and metabolism. Plastic surgery reshapes the outer contours of the body and neither treats obesity nor affects metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Using modern laparoscopic technique, we perform the operation via 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, leaving marks that are nearly invisible after healing.
What diet do I need to follow?
The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on high-calorie, fatty food.
What types of bariatric surgery are there?
Four main bariatric surgery types are available at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is picked individually, considering 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, bariatric surgery makes vitamins a must. Since digestive anatomy is changed, absorption of some nutrients drops, and regular vitamin and mineral supplements become permanent in the patient's life.
Can the weight come back?
It is possible to regain weight after bariatric surgery, but very unlikely if you follow your doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are essential.

Bariatric surgery in San Antonio: from consultation to result
Sleeve gastrectomy turns most of the stomach into a narrow tube, reducing portion size and levels of ghrelin, the hunger hormone. It suits a BMI of 35 to 45, with patients losing on average 60–70% of excess weight. For anyone from San Antonio with a higher BMI or type 2 diabetes, a bypass may fit better; the surgeon compares options at the consultation.
A personal coordinator is assigned from day one, so no one goes through the process alone. After the first examination, each patient gets an individual diagnostic programme to identify every disorder in the body. Then the surgeon selects the method and performs the laparoscopic operation, and a doctor stays nearby 24/7. That is the sequence for everyone from San Antonio.
One package covers the full journey, from consultation to final result. There are no separate charges added later: ward, meals, nursing care and coordinator support are included. To find out whether surgery suits you, patients in San Antonio can book a free surgeon consultation; the doctor reviews BMI, health and weight history and recommends a method.
