Who is Bariatric SurgeryFor

Bariatric surgery is a weight loss procedure recommended for individuals with severe obesity who have not achieved long-term weight loss through diet, exercise, or medication. It is commonly recommended for those who:

• Have a body mass index (BMI) of 40 or higher
• Have a BMI of 35 or higher with obesity-related health conditions like type 2 diabetes, hypertension, or sleep apnea.
• Are unable to maintain a healthy weight loss through conventional methods
• Need to reduce obesity-related health risks and improve quality of life

Key Takeaways of the Bariatric Surgery Procedure

• Type of Procedure: Surgical weight loss procedure that includes different techniques like gastric bypass, sleeve gastrectomy, and adjustable gastric banding to alter the digestive system and limit food intake or nutrient absorption.
• Duration: Typically takes 1 to 3 hours, depending on the specific type of bariatric surgery being performed.
• Anesthesia Used: General anesthesia is used, keeping the patient unconscious and pain-free during the surgery.
• Recovery Time: Hospital stay lasts around 2 to 5 days. Initial recovery takes 2 to 4 weeks, with complete recovery and lifestyle adjustments continuing over several months. Patients typically follow a strict diet and physical activity plan for long-term success.

Types of Bariatric Surgery Procedures

• Gastric Bypass (Roux-en-Y Gastric Bypass): A small pouch is created at the top of the stomach and directly connected to the small intestine, bypassing part of the stomach and upper intestine. This reduces the amount of food you can eat and lowers calorie absorption.
• Sleeve Gastrectomy: A large portion of the stomach is removed, leaving a smaller, banana-shaped "sleeve." This reduces stomach capacity and triggers hormonal changes that help control appetite and blood sugar levels.
• Adjustable Gastric Band (Lap-Band): A band is placed near the top of the stomach to create a small pouch. The size of the opening between the pouch and the rest of the stomach can be adjusted, helping to control food intake.
• Biliopancreatic Diversion with Duodenal Switch (BPD/DS): This complex surgery removes part of the stomach and reroutes a significant portion of the small intestine. It combines restrictive and malabsorptive techniques to promote weight loss.
• Bariatric Revision Surgery: For individuals who have had prior bariatric procedures, revision surgery may be needed to address complications, insufficient weight loss, or other issues.

Indications of Bariatric Surgery

Bariatric surgery aims to promote weight loss, improve or resolve obesity-related health problems, and enhance overall quality of life.

Here are the main indications and purposes of bariatric surgery:

Severe Obesity

Bariatric surgery is typically recommended for those with a BMI of 40 or higher. It can also be considered for individuals with a BMI of 35 or higher if they have obesity-related severe health issues.

Obesity-Related Health Conditions

Bariatric surgery may benefit individuals with health conditions that improve with weight loss, including:

• Type 2 diabetes
• Hypertension (high blood pressure)
• Sleep apnea
• High cholesterol
• Non-alcoholic fatty liver disease

Failure of Non-Surgical Methods

Candidates for bariatric surgery usually have attempted weight loss through:

• Diet changes
• Exercise
• Behavioural modifications

If these methods haven't worked, surgery may be an option.

Motivation and Commitment

Post-surgery success requires a commitment to:

• Healthy eating
• Regular exercise
• Follow-up appointments

Make sure you are ready to make these lifestyle changes!

Purposes of Bariatric Surgery

Weight Loss Benefits of Bariatric Surgery

Effective Weight Loss: Bariatric surgery helps with lasting weight loss by reducing stomach size or changing the digestive process. This limits how much food you can eat or absorb, leading to gradual weight loss.

Improvement of Health Conditions

Health Boost: It can significantly improve or resolve obesity-related issues like hypertension, type 2 diabetes, and sleep apnea, lowering your risk of health complications.

Better Quality of Life

Quality of Life: Successful weight loss can improve mobility, reduce joint pain, boost self-esteem, and enhance overall well-being.

Long-Term Weight Management

Long-Term Success: Bariatric surgery helps maintain weight loss better than non-surgical methods. However, you still need to commit to a healthy lifestyle with dietary changes and regular exercise.

Lower Mortality Risk

• Lower Risk: Studies show bariatric surgery reduces mortality risk in severely obese individuals significantly when related health conditions are improved.

How to Prepare for Bariatric Surgery?

• Consultation and Evaluation: Meet with a bariatric surgeon to discuss surgery options. Undergo physical exams, imaging, and blood tests to assess health.
• Education and Counseling: Attend informational sessions about surgery and recovery. Meet with a dietitian and mental health professional for guidance.
• Pre-Operative Requirements: Follow dietary guidelines and complete necessary tests like blood work, EKG, and pulmonary tests.
• Lifestyle Changes: Adopt a healthy diet, exercise regularly, and quit smoking to reduce Bariatric surgery risks.
• Medical Management: Manage chronic conditions like diabetes and hypertension with your healthcare provider.
• Support System: Build a support system of family and friends to assist during recovery.
• Pre-Operative Diet: Follow a specific low-calorie or liquid diet as instructed by your healthcare team.
• Psychological Preparation: Address emotional factors through counseling or support groups.
• Medications: Consult your doctor about medication adjustments before surgery.
• Logistics: Plan your hospital stay, arrange transportation, and prepare for home recovery.
• Post-Operative Preparation: Stock up on protein supplements, vitamins, and medications. Clear your schedule for recovery time.
• Final Consultation: Have a final meeting with your surgeon to address any last-minute questions before surgery.

Steps Involved in Bariatric Surgery

During a bariatric surgery, several steps are taken to achieve the desired weight loss and metabolic changes. The exact details may vary depending on the type of surgery being performed, but a general overview of what happens during bariatric surgery:

Anesthesia

You will receive anesthesia to ensure you're comfortable and pain-free throughout the procedure.

Incisions

Small incisions are made in the abdomen to give the surgeon access to the surgical area. In many cases, minimally invasive techniques (laparoscopic surgery) are used, involving tiny instruments and a camera.

Access to the Stomach

The surgeon uses the incisions to reach the stomach and digestive tract.

Surgical Technique

Different types of bariatric surgery use different techniques:

• Gastric Bypass (Roux-en-Y): A small pouch is created at the top of the stomach and connected to a lower part of the small intestine, bypassing a section of both the stomach and small intestine.
• Sleeve Gastrectomy: A large portion of the stomach is removed, leaving a smaller, banana-shaped "sleeve."
• Gastric Banding (Lap-Band): A band is placed around the top of the stomach to create a small pouch.
• Biliopancreatic Diversion with Duodenal Switch (BPD/DS): A portion of the stomach is removed, and a larger part of the small intestine is bypassed.

Closure and Healing

The incisions are carefully closed with sutures or staples, and the healing process begins.

Recovery and Monitoring

After the surgery, you'll be moved to a recovery area where medical staff will monitor your vital signs and ensure you wake up safely from the anesthesia.

Hospital Stay

Depending on the type of surgery and your health, you may stay in the hospital for a few days to recover and receive post-operative care.

Diet Progression

You will start with clear liquids, gradually move to soft foods, and eventually return to regular foods based on the guidance from your healthcare team.

Follow-up Care

Regular follow-up appointments will be scheduled to monitor your progress, adjust medications, and provide advice on diet and lifestyle changes.

Your health is everything - prioritize your well-being today.
