When you decide to pursue bariatric surgery and weight loss, you are taking one of the most important and meaningful steps toward improving your health and overall well-being. While surgery is not a quick fix, it is a powerful solution that helps you reset your relationship with food and build lasting habits.
At MyLife Bariatrics, our team of bariatric surgeons support patients through every stage of this transformation, including preparation and surgery to long-term weight-loss maintenance and success.
In this brief guide, we’ll walk you through what to expect before and after surgery, what the average weight loss after bariatric surgery looks like, and how to stay on track for years to come.
Understanding Bariatric Surgery and Weight Loss
Bariatric surgery refers to types of procedures that help people with obesity lose weight by changing the digestive system.
These surgeries either limit how much you can eat or how your body absorbs nutrients, or both. At MyLife Bariatrics, two of the most popular and effective options are:
- Gastric Sleeve Surgery (Sleeve Gastrectomy): In this procedure, about 60 to 80 percent of the stomach is removed, leaving a smaller, sleeve-shaped stomach. This limits the amount you can eat and reduces hunger hormones.
- Endoscopic Sleeve Gastroplasty (ESG): This is a less invasive, incisionless procedure that uses an endoscope to reshape the stomach with sutures. ESG reduces stomach volume without removing tissue, leading to weight loss and a shorter recovery time.
Both procedures can help patients achieve substantial, long-term results when combined with healthy eating, physical activity, and regular medical follow-up.
Preparing for Surgery: Setting the Foundation for Success
The preparation phase is an essential part of the bariatric journey. Before surgery, your medical team will help ensure you are physically and mentally ready. Preparation often includes:
- Nutritional counselling: Learning how to make balanced food choices and adjust portion sizes.
- Lifestyle adjustments: Reducing sugar, refined carbs, and processed foods while increasing protein intake.
- Psychological readiness: Understanding emotional triggers for eating and preparing for the lifestyle changes ahead.
- Pre-surgery diet: A short-term, shake-based diet may be recommended to reduce liver size and improve surgical safety.
This stage sets the tone for success. Patients who approach surgery with realistic expectations and a willingness to embrace change tend to see the most positive outcomes.
The Surgery and Immediate Recovery
Both gastric sleeve surgery and ESG are performed by highly trained bariatric surgeons using minimally invasive techniques. This approach reduces discomfort and allows for a faster recovery.
After surgery, patients typically:
- Go home 5-6 hours post-surgery or ESG
- Start on a liquid diet before gradually progressing to soft and then solid foods.
- Are guided closely by their MyLife Bariatrics care team, including our dieticians, Sarah and Ellie & Drs. Dennis, Ari and Karim.
Pain and fatigue are normal at first, but most patients notice improvements in energy levels and mobility within a week.
The Average Weight Loss After Bariatric Surgery
Weight loss varies depending on the procedure, adherence to aftercare plans, and individual factors. On average:
- Gastric Sleeve Surgery: Patients 25 to 35 percent total body weight within 12 to 18 months.
- Endoscopic Sleeve Gastroplasty: Patients may lose around 10 to 20 percent of their total body weight within 12 to 18 months.
These numbers are averages, and real results depend on consistency with nutrition, exercise, and follow-up care. Many patients also experience improvements in related health conditions such as type 2 diabetes, high blood pressure, and sleep apnea.
What About Nutrition After Bariatric Surgery?
An important topic for many patients is what to eat after surgery. Diet plays a central role in both recovery and long-term success.
After surgery, your eating plan will gradually change:
- Liquid phase: The first stage focuses on clear liquids, protein shakes, and hydration.
- Pureed foods: Soft, blended meals that are gentle on the stomach.
- Soft foods: Slowly reintroducing foods with more texture.
- Regular meals: Transitioning to a balanced diet of small, nutrient-dense portions.
It’s important to remember these nutrition recommendations:
- Prioritize protein at every meal to maintain muscle mass.
- Avoid sugary drinks, fried foods, and empty calories.
- Eat slowly and stop when you feel comfortably full.
- Take prescribed vitamin and mineral supplements to prevent deficiencies.
Registered dietitians at MyLife Bariatrics provide personalized guidance to help you meet your nutritional needs safely and sustainably.
Staying Active and Building Healthy Habits
Exercise is another cornerstone of long-term weight loss success. Starting small with a simple fitness plan is important. Even gentle walking can make a difference early on. As you heal and gain strength, gradually increase your activity.
Many patients find success by incorporating:
- Low-impact activities: Swimming, cycling, or yoga to build endurance.
- Strength training: Helps preserve lean muscle and boosts metabolism.
- Active hobbies: Gardening, hiking, or dancing to make movement enjoyable.
Consistency matters more than intensity. The goal is to create habits that fit naturally into your lifestyle.
Long-Term Success: Maintaining Your Weight Loss
While bariatric surgery gives you a strong head start, maintaining weight loss needs your ongoing commitment. MyLife Bariatrics supports patients through follow-up appointments, education, and access to community resources.
Some strategies that help long-term include:
- Regular check-ins: With your surgical team and dietitian to monitor progress.
- Mindful eating: Paying attention to hunger and fullness cues.
- Support networks: Connecting with others who understand the journey.
- Setting new goals: Whether related to fitness, nutrition, or mental health, ongoing motivation helps maintain momentum.
It is also helpful to plan ahead for life changes that may affect your habits, such as travel, holidays, or stressful periods.
