FACP, Diplomate of the American Board of Obesity Medicine

Dr. Lauren Lemieux, MD is an internist and obesity medicine specialist who is passionate about helping her patients achieve their health goals.

More about Dr. Lemieux

What do you love most about your job?

What I love most about my job is the connections I make with my patients. To really understand how to help a patient reach their health goals, you have to get to know them and tailor your recommendations based on their unique lifestyle and needs. I also find it extremely rewarding to help my patients reverse many of their other medical problems, such as high blood pressure or diabetes, through weight loss and healthy lifestyle changes.

How do you go about making your treatment plans for FORM patients?

Coming up with treatment plans is one of my favorite parts of my work. In a way it’s like solving a puzzle, and it is different for every patient I see. I first start by trying to learn more about my patient and identify the factors that may be affecting his/her weight. For example, I want to learn about nutrition, physical activity, stress and sleep habits, and depending on what we discuss we may not cover everything in just one visit!  I also review their medical history to see how their weight is affecting other aspects of their health and the medications they are currently taking to see if any of those may be affecting weight. I believe in a collaborative approach to identify specific goals and strategies to achieve them. For all patients, nutrition and physical activity are important foundational components of their plan, but the specific details are unique to each person. Furthermore, they are not the only lifestyle factors we address. I will also consider whether a person is a candidate for pharmacotherapy for weight loss and what medication may be most effective. Treatment plans are also meant to evolve, and I reflect carefully on whether the plan is effective or needs to be modified at each visit.

Why do you love working with FORM patients?

I consider it a privilege to be part of my patient’s health care team. FORM patients are a highly motivated group of individuals who inspire me everyday as they pursue their health goals.  I love the experience of getting to know my patients, collaborating with them to overcome obstacles, and celebrating their successes!
