What is Morbid Obesity?

Morbid Obesity is a chronic, potentially life threatening disease characterized by the storage of excess fat in the body. Morbid obesity is typically defined as being 100 lbs. or more over ideal body weight, or having a Body Mass Index (BMI) of 40 or higher. A person can also be considered Morbidly Obese with a BMI of 35-40 with certain associated co-morbidities.

The Body Mass Index (BMI) is an approximate measure of body fat based on your height and weight. Find out yours to the left.

SCORES: BMI <20 under weight, BMI 20-24.9 healthy weight, BMI 25-29.9 over weight, BMI 30-34.9 obesity, BMI 35-39.9 severe obesity, BMI 40-49.9 morbid obesity, BMI  >50 super morbid obesity

Fox Bariatrics Weight Loss Surgery Options

Our mission is to provide the highest quality program tailored for you. Dr. Fox has performed 100’s of bariatric surgeries, however you are not a number to Dr. Fox. You will notice an atmosphere of warmth and caring throughout our office. It is our goal to help you decide whether obesity surgery is right for you or if you are a candidate for LapBand or Gastric Sleeve surgery.

Laparoscopic Gastric Sleeve

Laparoscopic Gastric Sleeve, also known as Sleeve Gastrectomy Surgery, is growing very quickly in popularity in the United States and around the world for many reasons:

  1. It results in effective, rapid and long term weight loss;
  2. It is considered less invasive with a much lower complication rate than Gastric Bypass and
  3. Patients LOVE IT!

The Laparoscopic Gastric Sleeve offered by the Fox Bariatric Center in Dallas, Texas is now available as a weight loss surgery alternative to gastric banding (Lap-Band) and the gastric bypass.

The Gastric Sleeve is also a good revision procedure for Band patients who have had either failed weight loss or had to have their Band removed.

Lap Band Surgery to Gastric Sleeve Surgery

Many lap band revision patients initially experienced excellent weight loss and health improvement following their lap band surgery, but for patients with a Lap Band who have not had the success that was anticipated or have plateaued with their weight loss, we are recommending removal of your Lap Band and converting to a Laparoscopic Gastric Sleeve.

The Gastric Sleeve offers rapid weight loss, no band adjustments as with the gastric band, fewer food restrictions, low risk of complications, and much more.

Call us at 972-566-4560 or send a Request a Consult to find out if your insurance benefits cover the conversion of the Lap Band to a Sleeve Gastrectomy.


The Lap Band Solution

The lap band surgical procedure is performed in an outpatient day surgery setting. Placement of the LAP-BAND® system will take about 1 hour under general anesthesia.

Approved by the FDA in June 2001, the BioEnterics® LAP-BAND® Adjustable Gastric Banding System is the most widely used adjustable surgical treatment for morbid obesity in the United States. It induces weight loss by reducing the capacity of the stomach, which restricts the amount of food that can be consumed. Since its clinical introduction in 1993, more than 450,000 lap band procedures have been performed around the world.


Roux-en-Y Gastric Bypass

Roux-en-Y Gastric Bypass is a combination procedure that combines both the restrictive and malabsorptive components. First, the stomach is stapled, cut, and divided to create a small pouch. The remainder of the stomach is not removed, but bypassed along with the first part of the intestines. Next, stapling and dividing of the intestines is performed to create a ‘Roux limb’ (named after Philibert Joseph Roux, a French surgeon in the 1800’s) that is now re-routed and connected to the small stomach pouch. The other end is attached into the side of the Roux limb of the intestine creating the ‘Y’ shape that gives the technique its name. This Roux limb of intestine that is attached to the small stomach pouch may be a ‘short limb’ or ‘long limb.’ As the ‘Y’ connection is moved farther down the intestinal tract, the amount of bowel capable of fully absorbing food (calories) and nutrients is reduced.


Vertical Banded Gastroplasty (VBG)

VBG is a restrictive procedure in which the upper part of the stomach (along the lesser curvature) near the esophagus is stapled vertically for about 2.5 inches to create a small stomach pouch. The outlet channel is restricted by wrapping a prosthetic mesh or silastic ring to prevent stretching as well as slowing the emptying of food. Unfortunately, there has been an over 20% failure rate with this operation as well as a high incidence of weight regain.

Biliopancreatic Diversion (BPD)

This operation involves stapling and cutting the upper stomach, usually horizontally, and removing about 70-80% of the lower stomach. This produces restriction of food intake and reduction of acid output. The remaining upper portion of the stomach is far larger than the ‘small pouch’ created for the gastric bypass. The principle of the anatomy is such that the small intestine is divided with one end attached to the stomach pouch. All the food passes through this shorter ‘alimentary limb’, but not much is absorbed (promotes malabsorption). The bile and pancreatic juices move through the longer ‘biliopancreatic limb’ which is connected toward the end of the intestine, a short distance before it enters into the colon. This short ‘common channel limb’ is where the food and digestive juices mix so food and nutrients may be absorbed.

Biliopancreatic Diversion with a “Duodenal Switch” (DS)

This procedure is a modification of the BPD. The vertical narrow tube ‘gastric sleeve’ of stomach is created, preserving the pylorus. The remaining portion of the stomach is removed. Transection of the duodenum (first part of the small intestine), just beyond the pylorus, is performed so that the bile and pancreatic drainage is bypassed. The alimentary limb of the intestine is connected to the duodenum. The ‘common channel limb’ is created as described above. Anatomically, the main difference between the DS and BPD is the shape and size of the stomach. Also, the BPD involves attaching the intestine to the stomach pouch, whereas in the DS, the intestine is attached to the duodenum. The malabsorptive component is essentially the same as the BPD. Surgeons use various formulas to determine the appropriate length of the alimentary channel and the common limb channel to regulate the amount of absorption of calories, proteins, and other nutrients.

Dr. Fox's Guidelines for Success


Following these important dietary guidelines along with following regular post-bariatric surgery maintenance will lead you down your road to success.

Weight Loss Surgery Dietary Guidelines


What to eat PRE-OP, POST-OP, and LONG TERM. As a lifestyle you must choose healthy and nutritional foods high in protein and low in carbohydrates, fats, and sugars.

Post-OP Exercise & Activity


Weight loss surgery is effective in reducing the number of calories eaten each day. Exercise adds to this by increasing the number of calories burned.

Post-OP Patient Visits


It is important to always have follow-up consultations with your surgeon periodically. Routine follow up with your surgeon and his health care team, as well as with your primary care physician (PCP), is MANDATORY.
