Bariatric Surgery in Tijuana, Mexico

Living with obesity can affect many aspects of physical health, mobility, daily activities, and quality of life.

For some individuals, maintaining significant weight loss through lifestyle changes and nonsurgical treatments alone can be challenging.

At Osuri Surgery in Tijuana, Mexico, we offer personalized evaluations for bariatric surgery, including Gastric Sleeve (Sleeve Gastrectomy) and Gastric Bypass (Roux-en-Y Gastric Bypass).

These procedures are designed to support substantial weight loss and may improve certain obesity-related medical conditions when combined with appropriate nutrition, lifestyle changes, and long-term medical follow-up.

Our approach emphasizes careful patient selection, medical evaluation, informed decision-making, and coordinated postoperative care.

Bariatric surgery, also known as metabolic or weight-loss surgery, includes procedures that modify the digestive system to help patients lose weight and improve metabolic health.

Depending on the operation, bariatric surgery may reduce the amount of food the stomach can hold, alter the movement of food through the digestive tract, and influence hormones involved in appetite, blood sugar regulation, and metabolism.

Bariatric surgery is not a cosmetic procedure or a substitute for healthy habits.

It is a medical treatment that requires:

• Comprehensive preoperative assessment.
• Evaluation of obesity-related health conditions.
• Nutritional counseling.
• Long-term dietary changes.
• Vitamin and mineral supplementation when indicated.
• Regular medical follow-up.
• Ongoing commitment to physical activity and healthy lifestyle habits.

The most appropriate procedure depends on your medical history, body mass index (BMI), eating patterns, metabolic conditions, and individual treatment goals.

Gastric sleeve surgery, medically known as sleeve gastrectomy, is a bariatric procedure in which approximately 75–80% of the stomach is removed, leaving a smaller, tube-shaped stomach.

The remaining stomach resembles a sleeve or narrow banana.

By reducing stomach capacity, the procedure helps patients feel satisfied with smaller portions of food.

Sleeve gastrectomy also affects gastrointestinal hormones involved in appetite and metabolism.

The procedure is generally performed laparoscopically or with another minimally invasive approach when appropriate.

Gastric sleeve surgery supports weight loss through several mechanisms.

Reduced Stomach Capacity

The smaller stomach limits the amount of food that can be comfortably consumed at one time.

Changes in Appetite Regulation

Removing a large portion of the stomach can affect hormones associated with hunger and satiety.

Smaller Meal Portions

Patients typically become satisfied with smaller meals, supporting reduced calorie intake when combined with appropriate nutritional habits.

Metabolic Effects

The procedure may improve blood sugar regulation and other obesity-related metabolic conditions.

Although gastric sleeve does not intentionally bypass the intestines, nutritional deficiencies can still develop, and long-term supplementation and monitoring remain important.

Potential benefits may include:

• Significant weight loss.
• Reduced stomach capacity.
• Improved portion control.
• Changes in appetite and satiety.
• Improvement in certain obesity-related health conditions.
• Better mobility and physical functioning.
• Improved quality of life for selected patients.
• No intentional intestinal bypass.
• A generally less complex intestinal reconstruction than gastric bypass.

Results vary according to starting weight, medical conditions, adherence to nutritional recommendations, physical activity, and long-term follow-up.

In appropriately selected patients, weight loss and metabolic changes may improve:

• Type 2 diabetes.
• High blood pressure.
• Obstructive sleep apnea.
• Abnormal cholesterol and triglyceride levels.
• Fatty liver disease.
• Joint discomfort associated with excess weight.
• Other obesity-related health concerns.

Improvement or remission of these conditions is not guaranteed.

Patients must continue appropriate medical care and should not discontinue prescribed medications without guidance.

Gastric sleeve surgery is generally performed under general anesthesia.

Your bariatric surgeon reviews your medical history, BMI, weight-related conditions, and overall surgical risk.

Small incisions are made in the abdomen, and specialized instruments are introduced.

A large portion of the stomach is removed, leaving a smaller sleeve-shaped stomach.

The surgeon evaluates the staple line and completes appropriate checks according to the surgical technique.

After surgery, patients are monitored for pain control, hydration, bleeding, and other early complications.

Dietary progression and discharge depend on the patient's clinical condition and the bariatric team's protocol.

Gastric sleeve is permanent and is not considered reversible, because a substantial portion of the stomach is removed.

Gastric bypass is a bariatric procedure that changes both stomach capacity and the route food takes through the digestive system.

The most commonly performed form is Roux-en-Y Gastric Bypass (RYGB).

During surgery, the surgeon creates a small stomach pouch and connects it to a section of the small intestine.

This allows food to bypass most of the stomach and the first portion of the small intestine.

The procedure affects food intake, nutrient absorption, and metabolic signaling.

Gastric bypass may be especially useful for selected patients with obesity-related metabolic conditions or significant gastroesophageal reflux disease (GERD).

Gastric bypass supports weight loss through several mechanisms.

Smaller Stomach Pouch

The newly created pouch holds a smaller amount of food, helping patients feel satisfied with smaller portions.

Changes in the Digestive Pathway

Food passes from the stomach pouch directly into a lower section of the small intestine.

Changes in Nutrient Absorption

The altered digestive pathway can reduce absorption of certain nutrients and contributes to the need for lifelong supplementation.

Hormonal and Metabolic Changes

Gastric bypass influences gastrointestinal hormones and metabolic pathways involved in appetite, blood sugar regulation, and insulin sensitivity.

These changes can contribute to meaningful improvements in weight and certain obesity-related medical conditions.

Potential benefits may include:

• Significant and sustained weight loss.
• Improved blood sugar regulation.
• Improvement or remission of type 2 diabetes in selected patients.
• Improvement in obesity-related high blood pressure.
• Improvement in sleep apnea.
• Reduced obesity-related health risks.
• Improvement in gastroesophageal reflux symptoms for many patients.
• Improved mobility and quality of life.

Results vary, and lifelong medical and nutritional follow-up is essential.

Roux-en-Y Gastric Bypass is generally performed using minimally invasive surgical techniques under general anesthesia.

Your bariatric surgeon reviews your medical history, weight-related conditions, nutritional status, and individual surgical risk.

The surgeon divides the stomach to create a small pouch that will receive food.

The remaining stomach stays in the body but is excluded from the direct passage of food.

A section of the small intestine is connected to the new stomach pouch.

Another intestinal connection is created to allow digestive fluids to mix with food farther along the digestive tract.

The surgeon evaluates the surgical connections and checks for potential problems according to the operative protocol.

Patients are monitored for hydration, pain control, bleeding, and early postoperative complications.

Diet progression and discharge are determined by the bariatric team.

Gastric bypass involves permanent anatomical changes. Although reversal may be technically possible in selected circumstances, it is complex and not routinely performed.

Neither procedure is automatically the best choice for every patient.

The appropriate operation depends on your medical history, metabolic conditions, reflux symptoms, nutritional risk, and individual goals.

Bariatric surgery may be considered for adults with obesity who meet accepted clinical criteria and have undergone appropriate medical evaluation.

Current professional guidelines recommend considering metabolic and bariatric surgery for:

• Adults with a BMI of 35 or higher, regardless of the presence or severity of obesity-related conditions.
• Adults with type 2 diabetes and a BMI of 30 or higher.
• Selected adults with a BMI between 30 and 34.9 who have not achieved durable weight loss or improvement in obesity-related conditions with nonsurgical treatment.

BMI thresholds may differ for certain populations.

Individual eligibility also depends on overall health, surgical risk, psychological readiness, and the ability to participate in long-term follow-up.

Not everyone who meets a BMI threshold is automatically a suitable candidate.

Your bariatric surgeon will carefully review medical conditions that may affect surgical planning, including:

• Type 2 diabetes.
• High blood pressure.
• Heart or lung disease.
• Obstructive sleep apnea.
• Gastroesophageal reflux disease.
• Previous abdominal surgery.
• Liver disease.
• Kidney disease.
• Nutritional deficiencies.
• History of blood clots.
• Mental health conditions or eating disorders.

These conditions do not necessarily prevent surgery, but they may require additional evaluation or treatment before proceeding.

At Osuri Surgery, bariatric surgery planning begins with a comprehensive medical evaluation.

Your preoperative assessment may include:

• Complete medical history.
• Blood and urine testing.
• Blood glucose and HbA1c testing.
• Kidney and liver function testing.
• Nutritional laboratory assessment.
• Electrocardiogram (EKG), when indicated.
• Internal medicine or cardiology evaluation when needed.
• Sleep apnea assessment.
• Anesthesia evaluation.
• Nutritional counseling.
• Psychological or behavioral health assessment when indicated.
• Upper gastrointestinal evaluation when appropriate.

Follow Your Bariatric Nutrition Plan

Your surgical team may recommend a special diet before surgery to support safer operative conditions.

Stop Smoking and Nicotine Use

Smoking increases the risk of complications, including wound healing problems and, particularly after gastric bypass, marginal ulcers.

Follow your bariatric team's nicotine cessation requirements.

Review All Medications

Certain medications, including diabetes treatments, blood thinners, and medications affecting gastric emptying, may require individualized instructions.

Do not stop prescribed medications without medical guidance.

Avoid Alcohol and Other Substances as Directed

Alcohol use and other substance-related risks should be discussed openly with your medical team.

Prepare for Long-Term Lifestyle Changes

Bariatric surgery requires lasting changes in eating habits, supplementation, physical activity, and medical follow-up.

Following bariatric surgery, the stomach and digestive system need time to heal.

Your bariatric team will provide a structured dietary progression.

The exact schedule varies by procedure and medical protocol.

During the earliest postoperative period, patients begin with small amounts of approved clear liquids when medically appropriate.

The goal is to maintain hydration while monitoring tolerance.

Patients gradually advance to approved liquid nutrition, often including protein-rich beverages.

Protein and hydration are important for healing and nutritional recovery.

Soft, smooth foods may be introduced according to the bariatric team's instructions.

Portions remain small.

Patients gradually begin consuming soft, easy-to-tolerate foods.

Eating slowly and chewing thoroughly are important.

Patients transition toward a balanced, protein-focused eating plan with appropriately sized portions.

Long-term recommendations generally include:

• Prioritizing protein intake.
• Drinking sufficient fluids between meals.
• Eating slowly and stopping when satisfied.
• Avoiding frequent high-calorie beverages.
• Limiting foods that cause discomfort or dumping symptoms.
• Taking prescribed vitamin and mineral supplements.
• Attending regular nutritional follow-up appointments.

The timing of each dietary stage must follow your bariatric team's instructions.

Nutritional monitoring is essential after both gastric sleeve and gastric bypass.

Because food intake is reduced and nutrient absorption may change, patients can develop vitamin and mineral deficiencies.

Common nutrients requiring monitoring include:

• Iron.
• Vitamin B12.
• Folate.
• Calcium.
• Vitamin D.
• Thiamine (vitamin B1).
• Other vitamins and minerals according to the procedure and laboratory results.

Patients typically require lifelong bariatric vitamin and mineral supplementation.

Gastric bypass generally carries a higher risk of certain nutritional deficiencies because part of the small intestine is bypassed.

Your medical team will recommend appropriate supplements and laboratory monitoring.

Recovery varies according to the procedure, medical history, and individual healing.

Most gastric sleeve and Roux-en-Y gastric bypass procedures are performed using minimally invasive techniques when appropriate.

Patients are monitored for:

• Pain and nausea.
• Hydration.
• Bleeding.
• Breathing and oxygen levels.
• Early signs of surgical complications.
• Tolerance of approved liquids.

Gentle walking is encouraged as soon as medically appropriate to support circulation.

Hospital discharge depends on clinical stability and the bariatric team's assessment.

Patients continue their prescribed liquid diet and gradually increase light daily activity.

Fatigue, reduced appetite, and mild abdominal discomfort may occur.

Adequate hydration is especially important.

Many patients gradually resume light activities and nonphysical work, depending on their recovery.

Diet progression continues according to the prescribed bariatric plan.

Patients may gradually increase physical activity with medical approval.

Dietary tolerance continues to improve, although meal portions remain significantly smaller than before surgery.

Weight loss generally continues as patients adapt to their new eating habits.

Regular follow-up is important for monitoring weight, hydration, nutritional status, and obesity-related medical conditions.

Weight loss varies depending on the procedure, starting weight, metabolic health, lifestyle habits, and long-term follow-up.

Many patients experience substantial weight loss during the first 12–18 months after surgery.

In clinical studies, average total body weight loss at approximately one year is often in the range of:

• Gastric Sleeve: Approximately 20–30%.
• Roux-en-Y Gastric Bypass: Approximately 25–35%.

These ranges are general estimates, not guarantees. Results vary, and weight regain can occur over time.

Long-term success depends on ongoing nutritional care, physical activity, behavioral support, and medical monitoring.

Like all major surgical procedures, bariatric surgery involves potential risks.

Possible complications include:

• Bleeding or infection.
• Blood clots, including deep vein thrombosis and pulmonary embolism.
• Adverse reactions to anesthesia.
• Injury to nearby organs.
• Leakage from staple lines or surgical connections.
• Abdominal infection.
• Dehydration.
• Bowel obstruction.
• The possible need for additional surgery.
• Death, although uncommon.

Additional risks may include:

• Staple line leakage.
• Narrowing or twisting of the gastric sleeve.
• Development or worsening of acid reflux.
• Persistent nausea or vomiting.
• Nutritional deficiencies.
• Inadequate weight loss or weight regain.

Additional risks may include:

• Leakage at intestinal connections.
• Internal hernia.
• Bowel obstruction.
• Marginal ulcers.
• Dumping syndrome.
• Reactive hypoglycemia.
• Nutritional deficiencies.
• Strictures at surgical connections.
• Weight regain or inadequate weight loss.

Bariatric surgery requires careful patient selection and long-term follow-up to identify and manage complications.

Seek urgent medical evaluation if you experience:

• Severe or worsening abdominal pain.
• Persistent rapid heartbeat.
• Fever or chills.
• Repeated vomiting or inability to tolerate fluids.
• Chest pain or difficulty breathing.
• Fainting or severe weakness.
• Significant bleeding.
• Signs of severe dehydration.
• Painful swelling in one leg.

These symptoms may indicate serious complications and should not be ignored.

Bariatric surgery can produce substantial and durable weight loss, but long-term results depend on continued care.

Patients are encouraged to maintain:

• Regular bariatric medical appointments.
• Lifelong vitamin and mineral supplementation.
• Routine laboratory testing.
• Adequate protein intake.
• Healthy hydration habits.
• Regular physical activity.
• Appropriate management of obesity-related conditions.
• Behavioral and nutritional support when needed.

Weight regain can occur after either procedure.

Early follow-up and treatment adjustments can help address weight regain or nutritional problems.

Significant weight loss can improve health and mobility, but it may also leave excess skin around the abdomen, arms, thighs, breasts, and lower body.

Some patients later consider plastic surgery to remove excess skin and improve body contours.

At Osuri Surgery, post-weight-loss body contouring options may include:

• Tummy Tuck (Abdominoplasty).
• Extended or Circumferential Tummy Tuck.
• Arm Lift (Brachioplasty).
• Thigh Lift (Cruroplasty).
• Breast Lift.
• Lower Body Lift and other selected procedures.

Body contouring is generally considered after weight has stabilized and nutritional status has been optimized.

The appropriate timing depends on the patient's weight-loss progress, medical condition, and surgical evaluation.

At Osuri Surgery Tijuana, our team can assist patients traveling from the United States and other locations with planning their surgical visit.

Appropriate recovery arrangements depend on the type of bariatric procedure, the patient's medical needs, and the bariatric surgeon's recommendations.

Patients must have access to timely medical evaluation if postoperative complications develop.

Any recovery accommodation must be suitable for the patient's clinical condition and should not replace hospital care when hospital-level monitoring is required.

We offer transportation coordination between San Diego International Airport, Tijuana, the hospital, and approved recovery accommodations.

Our team can assist with planning arrival and return travel.

Patients should not travel long distances until medically cleared by their bariatric surgeon.

At Osuri Surgery, we believe bariatric surgery should be approached as a comprehensive medical treatment rather than simply a weight-loss procedure.

Our approach emphasizes:

• Evaluation by a qualified bariatric surgical team.
• Individualized treatment planning.
• Comprehensive preoperative assessments.
• Appropriate hospital facilities.
• Qualified anesthesia professionals.
• Nutritional preparation and education.
• Postoperative medical monitoring.
• Long-term follow-up planning.
• Assistance for international patients.

Our goal is to help patients understand their surgical options, risks, and responsibilities before making a treatment decision.

Gastric sleeve removes a large portion of the stomach, leaving a smaller stomach without intentionally bypassing the intestines.

Gastric bypass creates a small stomach pouch and reroutes part of the small intestine.

Both support weight loss, but they differ in digestive effects, nutritional risks, and potential benefits.

Neither procedure is best for everyone.

Gastric bypass may be preferred in selected patients with significant acid reflux or certain metabolic conditions.

Gastric sleeve may be appropriate for patients who would benefit from a procedure without intestinal rerouting.

Your bariatric surgeon will recommend an approach based on your individual medical needs.

No. Gastric sleeve permanently removes a large portion of the stomach.

Gastric bypass reversal may be technically possible in selected situations, but it is complex and not routinely performed.

It should be considered a procedure that creates permanent anatomical changes.

Weight loss varies.

Many patients lose a substantial percentage of their total body weight during the first 12–18 months.

Individual results depend on the procedure, starting weight, medical conditions, and long-term lifestyle changes.

Yes. Both gastric sleeve and gastric bypass may improve blood sugar control, and some patients experience diabetes remission.

However, remission is not guaranteed, and ongoing medical monitoring remains important.

Yes. Gastric sleeve may cause new reflux symptoms or worsen existing gastroesophageal reflux disease in some patients.

This is an important consideration when choosing between procedures.

Yes. Lifelong vitamin and mineral supplementation and regular laboratory monitoring are generally required after bariatric surgery.

The specific regimen depends on the procedure and individual nutritional needs.

Hospital stays vary according to the procedure, the patient's health, and recovery progress.

Many patients undergoing uncomplicated minimally invasive bariatric surgery are discharged within approximately one to three days, but longer hospitalization may be necessary.

Many patients gradually resume light activities within one to two weeks.

Returning to strenuous work or exercise generally requires additional recovery time and medical clearance.

Yes. Weight regain is possible after either procedure.

Long-term nutritional care, physical activity, and medical follow-up are important for maintaining results.

Many patients consider body contouring surgery after significant weight loss.

Your weight should be stable, and nutritional deficiencies must be addressed before elective plastic surgery.

The cost depends on the selected procedure, medical evaluation, hospital requirements, and individual treatment needs.
