Summary:
- Bariatric surgery procedures reduce stomach size and change how your body processes food, supporting long-term weight loss.
- Beyond weight loss, they also improve metabolic health, helping with diabetes, blood pressure, and cholesterol.
- Bariatric surgery is typically considered if your BMI is ≥35, or ≥30 with obesity-related conditions like type 2 diabetes or hypertension.
Carrying excess weight can affect more than your appearance, increasing your risk for conditions like type 2 diabetes, high blood pressure, and heart disease.
This is why some people turn to bariatric surgery, not just to help with weight reduction, but to improve their overall metabolic health and quality of life.
Keep reading to learn more about the different types of bariatric surgery and what you can expect after a procedure.
What Is Bariatric Surgery?
Bariatric surgery refers to a range of procedures designed to help you lose weight by altering the size or function of your stomach and digestive system.
Types of Bariatric Surgery
Common procedures include:
- Endoscopic Sleeve Gastroplasty (ESG): This is a minimally invasive procedure that reduces your stomach size from the inside without any external incisions.
Using a flexible camera and sutures, your specialist reshapes the stomach so you feel full sooner and eat less, supporting weight loss while avoiding traditional surgery. ESG can be an option if you’ve struggled with diet and exercise and prefer a less invasive approach. - Laparoscopic Roux‑en‑Y Gastric Bypass (RYGB): In this procedure, your specialist creates a small stomach pouch and connects it directly to the small intestine, bypassing part of the stomach and upper intestine. This limits how much you can eat and reduces calorie absorption.
- Sleeve Gastrectomy: During a sleeve gastrectomy, a large portion of your stomach is removed, leaving a smaller, tube‑shaped stomach. This reduces the amount of food you can eat and triggers hormonal changes that help support sustained weight loss and improve obesity‑related health issues.
Each approach has specific benefits and considerations, and your specialist will help determine which is best for you.
How Surgery Supports Weight Loss
Bariatric surgery changes the way your body processes food, helping you feel satisfied with smaller portions. These adjustments support consistent weight loss while reducing the risk of regaining weight.
Who Is Eligible For Surgery
Bariatric surgery is typically considered for adults with a body mass index (BMI) of 35 or higher, or a BMI of 30–34 with obesity-related conditions such as diabetes or hypertension.
Health Benefits Beyond Weight Loss
Bariatric surgery can do more than reduce weight. It actively improves several metabolic and cardiovascular conditions.
Improve Type 2 Diabetes
Many people see a significant reduction in blood sugar levels after bariatric surgery. In some cases, type 2 diabetes may go into remission, allowing you to manage your condition more effectively with fewer medications.
Reduce Hypertension
Weight loss and improved metabolic function often lead to lower blood pressure. This can reduce your reliance on antihypertensive medications and lower your long-term risk of heart disease and stroke.
Positive Effects on Heart and Cholesterol
Bariatric surgery can improve cholesterol profiles and reduce strain on your heart. These changes support better cardiovascular health and contribute to overall well-being.
Lifestyle Benefits
Beyond visible weight loss, bariatric surgery also supports lifestyle improvements by enhancing energy, mobility, and overall health.
Better Blood Sugar Control
Surgery helps regulate insulin and glucose levels, stabilising blood sugar and reducing fluctuations that can cause cravings and constant fatigue.
Reduced Medication Dependence
Many patients experience a decrease in the need for medications to manage diabetes, hypertension, and high cholesterol after surgery, helping simplify their daily routine.
Enhanced Energy and Mobility
As your weight drops and metabolism improves, you’ll feel more energetic and find everyday tasks, exercise, and hobbies less tiring.
