Understanding Obesity
Obesity is a chronic disease that increases your risk of serious health problems, including type 2 diabetes, joint pain, heart disease, stroke, high blood pressure and nonalcoholic fatty liver disease. Obesity affects a person through excess weight and weight-related health conditions. It is diagnosed by a measurement called the body mass index (BMI), a ratio of your height and weight. A BMI of 30 or higher would categorize you as obese, so you may benefit from treatment.
For some people, nutrition and lifestyle improvements alone may not be enough to achieve a healthy weight. Surgery may be a better and safer option to lose significant weight.

Am I a Candidate for Weight Loss Surgery?
To be a candidate for surgery, you need to meet the following criteria:
- Have a body mass index (BMI) of 40 or greater, or if you have weight-related health problems, such as diabetes or high blood pressure, a BMI of at least 35
- Understand the surgery and have realistic expectations about weight loss following surgery
- Demonstrate a willingness to make lifelong changes in lifestyle, dietary habits and exercise
Surgical Procedures We Offer
Laparoscopic Gastric Bypass Surgery
Laparoscopic gastric bypass surgery promotes weight loss in three ways:
- It makes the stomach much smaller, which helps you eat smaller meals and feel less hungry.
- It forces food to bypass the small intestine, where most food and nutrients are absorbed
- Hormone changes decrease hunger and increase how full you feel after a meal
.
- Any fluids for 30 minutes before and after your meals
- Foods that flow easily through your pouch
- High-calorie meals and liquids
