Here are the top five things you should know before undergoing bariatric surgery.

1. Preparation is key

Preparing for bariatric surgery is crucial to ensure the best possible outcomes. Your healthcare team will guide you through a pre-surgery process that may include:

• Dietary Changes – Many patients need to follow a low-calorie, high-protein diet to shrink the liver and reduce surgical risks.
• Lifestyle Adjustments – Establishing healthy eating habits, increasing physical activity, and quitting smoking (if applicable) are essential before surgery.
• Psychological Readiness – A weight loss psychologist can help you address emotional eating habits and prepare mentally for the changes ahead.
• Medical Evaluations – You may need tests such as blood work, an ECG, or sleep studies to ensure you are fit for surgery.

2. Different types of bariatric surgery

Bariatric surgery is not a one-size-fits-all solution. The most common types include:

• Gastric Sleeve (Sleeve Gastrectomy) – Removes a portion of the stomach, reducing food intake and hunger hormones.
• Gastric Bypass (Roux-en-Y Gastric Bypass or Mini Bypass) – Creates a small stomach pouch and reroutes the intestines to limit food absorption.

Your surgeon will recommend the best option based on your health history and weight loss goals. Look for a surgeon with expertise in this area that is supported by a team of dietitians, exercise physiologists and psychologists for the best results. 

3. Weight loss is just the beginning

Bariatric surgery is a tool, not a cure. Long-term success depends on maintaining healthy habits, including:

• Eating a nutrient-dense diet with lean proteins, vegetables, and lowered carbohydrates.
• Avoiding high-calorie, sugary, and processed foods.
• Committing to regular physical activity.
• Taking prescribed vitamin and mineral supplements to prevent deficiencies.
• Attending follow-up appointments and support groups to stay on track.

4. Possible risks and complications

Like any surgery, bariatric procedures carry risks. These may include:

• Short-term Risks: Infection, blood clots, or reactions to anesthesia.
• Long-term Complications: Nutritional deficiencies, acid reflux, dumping syndrome (rapid food movement into the small intestine), or weight regain.

Choosing an experienced bariatric team and following medical advice can help reduce these risks.

5. Emotional and social adjustments

Weight loss surgery impacts not only your physical health but also your emotional well-being and relationships. Some key considerations include:

• Body Image Changes – Adjusting to a new body shape can take time.
• Emotional Eating Challenges – Some people struggle with finding new coping mechanisms.
• Social Situations – Eating out and attending gatherings may feel different post-surgery.
• Support Networks – Connecting with a weight loss psychologist or support groups can provide encouragement and guidance.

Bariatric surgery is a powerful tool for weight loss and health improvement, but it requires a supportive team approach and lifestyle changes for long-term success. Preparing properly, understanding the procedure, and embracing a healthy lifestyle are essential steps in your journey.
