Roux-en-Y Gastric Bypass Surgery Ann Arbor

One of the weight loss surgeries offered by Dr. Taylor to patients in Ypsilanti Michigan (MI) is the Roux-en-Y gastric bypass surgery. Until quite recently, Gastric bypass was the most common weight loss surgery performed in the United States, and combines both restrictive and malabsorptive weight loss techniques. Gastric sleeve surgery took over as the most common surgery in 2015.

What Is Gastric Bypass?


Gastric bypass reduces the size of your stomach and reroutes the digestive system to decrease the amount of calories absorbed by the body. Roux-en-Y surgery is one type of gastric bypass surgery.

Roux-en-Y Gastric Bypass Step-by-Step:

  1. Surgeon staples the stomach across the top, creating a small pouch that holds about one ounce of food.
  2. The pouch is separated from the rest of the stomach.
  3. The small intestine is cut and one end is sewn directly onto the new stomach pouch. Food will now bypass the bottom portion of the stomach and the first section of the small intestine.

In many cases, gastric bypass can be performed laparoscopically using small incisions and special surgical instruments instead of one large abdominal opening. This reduces the risk of infection and shortens the recovery time.

What to Expect After Surgery

In order to experience the best results possible, there are certain changes you’ll need to make before and after gastric bypass surgery. Some of these changes may include:

  • Eating smaller meals – the smaller stomach size will help you practice portion control.
  • Making healthier food choices – eating certain foods, such as refined sugars, may cause “dumping” after gastric bypass.
  • Taking nutritional supplements – this will ensure your body gets essential vitamins and minerals that may not be easily absorbed after gastric bypass.
  • Increasing physical activity – adding exercise to your daily routine will help you maintain your weight loss and improve your overall health.

Working closely with your healthcare team and a strong support network can make it easier to commit to these changes.
