Bariatric Center

Bariatric & Weight Loss Services in Lake Charles

Obesity is recognized as a persistent, progressive disease that needs medical treatment; it increases the risk of developing more than 40 other diseases and health conditions, including type 2 diabetes, cardiovascular disease, and certain cancers, and can impact quality of life.

Weight loss (bariatric) surgery is the most effective and long-lasting treatment for severe obesity. It could be a solution for anyone who has struggled with obesity when traditional weight loss methods haven’t worked. Bariatric surgery promotes significant weight loss, which can improve weight-related health conditions and emotional well-being, increase energy and self-confidence, and overall better health, making it easier to perform specific tasks and participate in certain activities. 

The CHRISTUS Ochsner Bariatric Center of SWLA offers a premiere choice for weight loss surgery, featuring a team-based treatment program designed to help patients navigate pre-operative preparation and support post-operative recovery. We provide comprehensive education, follow-up care, and monthly support group sessions to assist in maintaining healthier habits.
