What are we?

Every weight loss journey is different. We are here to help you find the right path for you. Grinnell Bariatrics is a team of professionals dedicated to help you with different options to reach your weight loss destination. This journey will change your life. 

At Grinnell Regional Medical Center, our bariatrics teams has provided advanced bariatric weight loss and surgical care in Central Iowa for more than 30 years, performing over 2,000 bariatric weight-loss surgeries. Grinnell Bariatrics was one of the first centers of excellence in Iowa. We have sustained our center of excellence certification. 

Weight-loss surgery, called bariatric surgery, reduces the size of the stomach by either reshaping it or placing a band around a portion of it. Because the stomach is smaller, patients feel fuller faster and thus eat smaller meals. These changes in eating habits lead to successful weight loss and maintenance. Patients must also remain physically active to improve their overall health and wellness.

Bariatric surgery is the only option today that effectively treats obesity in people for whom more conservative measures such as diet, exercise and medication have not been effective. 

What surgery options are available at Grinnell Bariatrics

ROUX-EN-Y GATRIC BYPASS

This weight loss surgery makes your stomach smaller and causes food to bypass part of the small intestine. Our surgeons will divide the stomach into two parts: an upper “pouch” and a lower, unused portion. The "pouch" is a small pocket that can only hold about one ounce of food, or about 1/8 of a cup. After creating the pouch, part of the intestine is connected to the pouch –this leads to the “bypassing” of the lower part of the stomach and a few feet of small intestine. Gastric Bypass is generally performed laparoscopically.

GASTRIC SLEEVE

If you choose this path for weight loss, this surgery makes your stomach smaller. A portion of the stomach is removed, converting the stomach into a long narrow tube. This surgery does not interrupt the usual intestinal continuity. This operation is done laparoscopically or robotically.

GASTRIC BYPASS REVISION

Gastric bypass surgery has changed immensely since it first began. Perhaps you’ve already begun your weight loss journey, but may need corrective revision due to complications or reduced effectiveness.  

Grinnell Bariatrics welcomes patients who have had previous operations for obesity. Your Grinnell Bariatrics support team is known for their expertise and experience with these complicated cases and Grinnell Regional Medical Center is the only hospital in Iowa where such procedures are routinely performed.

MEDICAL WEIGHT LOSS

Surgery may not be the best treatment for your weight loss journey. Sometimes there are medical options you have not even considered, yet. Grinnell Bariatrics and Grinnell Regional Medical Center offer a comprehensive medical weight-loss program under such circumstances that includes disease management, behavioral therapy, nutritional education, and fitness recommendations to help our patients make a speedy recovery

The Grinnell Bariatrics team is dedicated to helping you succeed. Nothing is more important than answering your questions or taking the time to understand your goals. They work with you extensively to determine which type of surgery is best for you. As an American College of Surgeons Center of Excellence, Grinnell Bariatrics has everything you need to be successful on your weight loss journey. 

What are the risks of surgery? 

All major surgery comes with risks, and the risks are different for each patient. At the Grinnell Regional Medical Center, our surgeons have better outcomes than most. During your first appointment, your surgeon will explain your individual risk level. 

How do I determine if this is right for me? 

Grinnell Bariatrics follows guidelines supported by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program in order to determine a patient's eligibility for weight-loss surgery. Rather than using weight, we use body mass index (BMI) as a criteria for surgery. Individuals are candidates for surgery if:

  •  Their BMI is greater than 40 or between 35 and 40 with major obesity-related medical problems, e.g. diabetes, hypertension, hyperchloremic, sleep apnea. Click here to calculate your BMI.
  • They have failed previous attempts at weight loss in a medically supervised program

Before becoming eligible for surgery, you will meet with our surgeons, dietitians, psychologists, and members of our nursing staff for a full evaluation.

What is required of me before I'm scheduled for surgery? 

Your team of nurses, surgeons, therapists, dietitian, and wellness specialists will work with you for several months prior to your surgery. Some insurance companies require a patient to be in a physician-supervised weight-loss program for at least six-months before surgery. 

You will complete a surgical consultation, mental health consultation, diagnostic testing, pre-surgery education class, pre-operative interview, and pre-operative physical exam. 

Will my insurance cover bariatric surgery?

Most insurance companies cover weight-loss surgery providing you meet certain medical criteria. For example, you may be required to provide documentation from your physician of six to 12 months of medically supervised weight loss. Before you come for your first appointment, please call your insurance company to find out if weight-loss surgery is covered. Our patient coordinators, who are experienced in working with insurance companies, will assist you in determining your individual coverage. 

If I am interested in weight-loss surgery, what is my first step?

Though it took Henry nearly eight years to be “ready” for this surgery, she can’t say enough positive. 

“The transformation is amazing. I went from barely being able to walk from the handicapped parking space into my children’s school. Now, I volunteer in the school. I travel, and I do my own yard work. I have a life.”
