New Patient Health Questionnaire
Our surgeon usually recommends Roux-en-Y Gastric Bypass or Mini Gastric Bypass Surgery for those patients who eat continuously throughout the day or who are addicted to sweets. Because it restricts appetite and limits absorption of nutrients and calories, Roux-en Y Gastric Bypass allows patients to achieve rapid and lasting weight loss. To be a candidate for Roux-en-Y Gastric Bypass, you must have a body mass index (BMI) of at least 35. If you also suffer from certain co-morbid physical conditions, you may qualify with a BMI of less than 35.

Dr. Huacuz performs Roux-en- Y gastric bypass surgery laparoscopically, through  a series of very small incisions through which he passes the laparoscope, or optical telescope, separating a small stomach pouch directly below the esophagus. In the next step in the Roux-en- Y gastric bypass procedure, the surgeon cuts the small intestine 20 inches after its origin, then attaches the end still connected to the lower intestinal tract directly to the new stomach pouch. The end still attached to the now-detached stomach is connected to the small intestine about 40 to 60 inches down the intestinal tract. Afterward, ingested food passes only through the limb of intestine attached to the small stomach pouch, also known as the Roux limb. Food does not pass through the bypassed limb of intestine.

Nutrients and calories are not absorbed in the Roux limb due to the absence of digestive juices there. However, those digestive juices continue to pass through the bypassed limb, meeting up with food much farther down the small intestine where the bypassed limb reconnects with the Roux limb. The longer the Roux limb, the less absorption of calories and nutrients to the body, the greater the weight loss.
