What to Expect
  1. Consultation - Once you contact us, we will schedule you for the first visit with a nurse practitioner. A complete evaluation by the nurse practitioner at your first visit is the foundation of your personalized weight loss program. The nurse practitioner will build a team of experts around your needs.
  2. Setting Weight Loss Goals - We will help you create personal goals and monitor your own food choices and exercise with journals, websites, and phone applications to increase mindfulness - your ability to recognize and make choices and actions that lead to good health. Our weight loss program is different from other diet, drug or exercise-based plans. We do not rely on single short-term solutions or other "quick fixes." Our patient-centered approach puts you in the driver's seat, empowering you to reach weight loss goals that lead to long-term, lifetime health.
  3. Weight Loss Tests - We offer baseline tests such as resting metabolic rate and exercise tolerance testing to evaluate your progress and some can be done right in our clinic. Your Healthy Lifestyles Program team will coordinate your care and any tests you need with your primary care doctor and other health providers.
  4. Measuring Success - With the Healthy Lifestyles Program, patients meet regularly with the nurse practitioner, registered dietitian and exercise physiologist to monitor progress. Objective and behavioral markers will be recorded at each visit to measure patient progress toward overall goals. Our health specialists will work with you to set weight loss goals and make changes to achieve them.

Surgical Weight Loss

Weight loss surgery (bariatric surgery) can be a very beneficial procedure, and is the beginning of a lifelong commitment to health. Because there are different types of bariatric surgery, it is important to consider a number of factors before selecting the procedure that is best for you.

  • Gastric Bypass
  • Lap-Band®
  • Gastric Sleeve

Bariatric surgery can be a life changing procedure with the potential goal of decreasing your excess body weight by at least 50% and resolving any diseases that are being caused or worsened by excess weight. It is important to note that bariatric surgery is not a way to lose weight fast and requires dedication to proper diet and exercise. There are a variety of bariatric surgeries that can be effective and are divided into groups by how they affect your digestive system. The three types of bariatric surgery performed at our Des Moines, Iowa office include Gastric Bypass, Lap-Band® and Gastric Sleeve.
