Helping You Reach Optimal Health 

The weight management experts at Catholic Health offer medical and surgical options to help you lose weight safely and effectively. Our weight loss programs provide the tools and support you need to reach and maintain a weight that’s healthy for you. The results can be life-changing.

Consequences of Obesity

If you are overweight, you are not alone. Obesity has reached epidemic proportions across the country. More than 40% of Americans are obese, according to the Centers for Disease Control. Anyone can become obese. Eating habits, activity level, medication use and genetics all play a role in your weight. Some cancers, such as endometrial, breast, kidney, gallbladder and liver, can also boost the likelihood of obesity.

Catholic Health is here to get you on track to lose those extra pounds that impact more than just the numbers on your scale. They affect your physical, mental, emotional and social health. Obesity increases your risk of depression and anxiety. It can erode your self-confidence and diminish your quality of life. Our dedicated team of specialists will help you be healthier and feel better.

Body Mass Index (BMI)

Obesity is defined by the Centers for Disease Control as a body mass index, or BMI, of 30 or more. BMI is a mathematical calculation that estimates your healthy weight based on your height. It provides a guideline to help your physician assess whether your weight is a health issue that should be addressed.

You are a candidate for weight loss surgery if you have a BMI of:

  • 40 or greater
  • 35 with medical problems related to obesity
  • 30 with Type 2 diabetes
