What is Gastric Bypass Surgery?
Gastric bypass surgery is a well-established procedure that has helped countless individuals achieve significant weight loss. But how exactly does gastric bypass surgery work? In this blog, we’ll explain the procedure, its benefits, and who might benefit from it.
What is Gastric Bypass Surgery?
Gastric bypass surgery, which incudes Roux en Y gastric bypass, is a procedure that reduces the size of your stomach and reroutes part of your digestive system. This restricts the amount of food you can eat and changes how your body absorbs nutrients, leading to weight loss.
How Does Gastric Bypass Surgery Work?
Gastric bypass surgery works through a combination of restriction and malabsorption:
- Restriction: By creating a smaller stomach pouch, the amount of food you can consume is significantly reduced, helping you feel full with less food and thereby lowering your calorie intake.
- Malabsorption: The surgery also bypasses a portion of the small intestine, which reduces the number of calories and nutrients absorbed by the body. This dual mechanism promotes substantial and sustained weight loss.
Benefits of Gastric Bypass Surgery
- Significant weight loss: Patients typically lose 60-80% of their excess weight within 12-18 months.
- Improved health: Many patients see improvement or resolution of obesity-related conditions like type 2 diabetes, high blood pressure, and heart disease.
- Long-Term Weight Management: Gastric bypass surgery offers lasting weight loss results when combined with a commitment to lifestyle changes.
- Improved Quality of Life: Patients often experience enhanced mobility, increased energy levels, and greater participation in activities they enjoy.
- Reduction in Hunger: Hormonal changes after surgery can lead to reduced appetite, making it easier to maintain a healthy diet.
Who is a Candidate for Gastric Bypass Surgery?
Gastric bypass surgery is typically recommended for individuals who:
- Have a Body Mass Index (BMI) of 40 or higher (severe obesity)
- Have a BMI of 30 or higher with obesity-related health issues such as type 2 diabetes, hypertension, or sleep apnea
- Have attempted and failed to achieve sustainable weight loss through diet and exercise alone
- Are committed to making long-term lifestyle changes, including a healthy diet and regular exercise, after surgery
- Have previously had other bariatric surgery however weight goals have not been achieved
Risks & Considerations of Gastric Bypass Surgery
While gastric bypass surgery is highly effective, it is important to be aware of the potential risks and considerations:
Surgical Complications: Possible complications include bleeding, infection, and leakage at the surgical connection sites, though these are relatively rare.
Nutrient Deficiencies: Because the surgery alters nutrient absorption, patients may need to take lifelong vitamin and mineral supplements to avoid deficiencies, particularly of iron, calcium, and vitamin B12.
Dumping Syndrome: Some patients may experience dumping syndrome, which occurs when food moves too quickly from the stomach to the small intestine, causing symptoms like nausea, diarrhoea, and dizziness.
Weight Regain: To maintain weight loss, it is crucial to follow dietary and lifestyle guidelines provided by your gastric bypass surgeon in Melbourne.
