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


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.


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 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.
