Bariatric Surgery Vs. Gastric Balloon: How To Choose The Right Option?
Bariatric surgery and gastric balloon are two effective procedures to treat obesity. They help you lose significant weight, improve your metabolic health, and enhance your quality of life. In this blog post, we discuss how these procedures work, the weight loss results you can expect, the limitations of each and how you can decide which option is best for you.
What is Bariatric Surgery?
Bariatric surgery refers to a group of medical procedures that involve making changes to your digestive system. The changes support weight loss in multiple ways:
- Your key hunger hormone (Gherlin) levels drop by 60-80%. This leads to reduced appetite and fewer cravings.
- The new stomach has little space for food. So, the amount of food you can comfortably eat at one meal is singificantly reduced.
- You consume fewer calories, which reduces the conversion of glucose into fat, limits fat storage, and improves insulin sensitivity.
Most patients lose 70-80% of excess weight within 1-2 years. In addition to weight loss, patients experience many metabolic health benefits such as improved blood sugar control, reduced joint pain, and better sleep quality.
While surgery gives a good start, long-term weight management relies on adherence to nutritional plan and healthy lifestyle habits. That is why, we have Healthy Eating and Lifestyle Program (HELP) integrated into all our bariatric procedures. Through HELP, we provides resources and tools to adjust to new eating patterns, manage cravings, heal your relationship with food, and stay accountable throughout the journey.
At Nords Weight Loss Clinic, we offer the following bariatric procedures:
Each procedure works differently, but all are grounded in strong clinical evidence and long-term safety data. A qualified bariatric specialist evaluates your health conditions and recommends the procedure if it suits your needs. Generally, surgery is recommended if you have a:
- BMI of 35 kg/m2 or higher
- BMI of 30 to 34.9 kg/m2, and you have been unsuccessful in losing weight through diet and exercise alone.
- Obesity-related conditions, such as Type 2 diabetes, hypertension (high blood pressure), or sleep apnea.
What is a Gastric Balloon?
A gastric balloon is a non-surgical, temporary weight loss procedure. During the procedure, a soft, deflated balloon is placed inside your stomach and then filled with saline or gas. The balloon occupies one-third of your stomach’s volume, reducing space available for food.
The gastric balloon is recommended if:
- You have not been able to lose weight through diet and exercise alone.
- You are overweight and have a body mass index (BMI) between 30 and 40, and excess weight is affecting your daily life and overall health.
- You prefer a non-surgical procedure to support your weight loss goals.
The balloon stays in the stomach for six to twelve months, after which it is removed in an outpatient setting. Most people lose an average 40% of ther excess body weight within 6-12 months duration that the balloon remains in the stomach. Everyone gets different results based on their eating and daily habits.

Which Option is Right for You?
There is no single best procedure for everyone. The right choice depends on your health, your goals, and your readyness for long-term change.
Meanwhile, a quick self-check can help you understand your options before you sit down with a bariatric specialist:
- What is your current BMI, and do you manage any weight-related health conditions like type 2 diabetes?
- Have previous attempts at weight loss through diet and exercise fallen short of your goals?
- What is driving your decision to explore a procedure (e.g., preparing for joint surgery, improving overall health, or boosting daily mobility)?
- Are you prepared to make long-term lifestyle and dietary changes to maintain your results after the procedure?
Once you have gone through these questions, the next step is to discuss your options with a specialist. At Nords Weight Loss Clinic, our bariatric specialists condut a thorough medical review, nutritional assessment, and psychological screening before recommending any procedure. We also emphasize that the procedures themselves are only one part of the transformation. The real success comes from the support system that surrounds you. So, we continue to provide structured, multidisciplinary care to promote weight loss, keep it off for longer, and experience fewer complications compared with those who navigate the journey alone.
Summary
Bariatric surgery and gastric balloons offer proven ways to achieve significant weight loss and improve long-term health. Determining which option best fits your goals depends entirely on your unique health profile. We encourage you to bring your questions to your consultation so we can discuss the right approach for you.
