What You Need to Know
Losing weight can be a lifelong struggle, especially when diet and exercise don’t yield lasting results. That’s where weight loss surgery, also known as bariatric surgery, comes in. In 2025, more people are turning to surgical options to not only shed pounds but also improve health conditions like diabetes, sleep apnea, and high blood pressure.
But with several surgery types available—and costs ranging from a few thousand to tens of thousands of dollars—it’s essential to know your options before making a decision.
Let’s dive into the most common weight loss surgeries, their costs, insurance coverage, risks, and what recovery looks like.
What Is Weight Loss Surgery?
Weight loss surgery refers to medical procedures that alter your digestive system to help you lose weight. These surgeries are often recommended for individuals with a BMI over 40, or a BMI over 35 with obesity-related health conditions.
They work by either:
- Restricting the amount of food your stomach can hold, or
- Changing how your body absorbs nutrients.
