Laparoscopic Roux-n-Y Gastric Bypass or simply "Gastric Bypass" has been around for over 60 years. It began as an "open" surgery (big incision) and now is performed via small incisions, much like all other surgeries on this site.

The idea behind our NJ gastric bypass is to increase satisfaction with small portions and decrease feelings of hunger, thereby resulting in a reduction in the number of calories a person is consuming.

This new configuration allows for much slower absorption of food, thus keeping a person satisfied with a very small meal. In other words, a saucer size plate of food will make you feel like a Thanksgiving dinner. You are full after just several bites! As an added benefit, the gastric bypass redirects certain hormones in the body, making it easier to control diabetes.

This is accomplished in two ways:

  • First, a small pouch is made by separating it from the rest of the stomach. The small pouch allows a person to feel full after just several bites of food.
  • Second, the intestines are re-routed and connected directly to the pouch, "short circuiting" or "bypassing" parts of the stomach and intestine.

Is the Gastric Bypass Right for You?

While many people find themselves struggling with their weight, a gastric bypass surgery is not for everyone. Most candidates for our gastric bypass surgery in NJ are at least 75 pounds overweight with a body mass index (BMI) of 40 or higher. Some people who fall slightly below these thresholds may also be good candidates for a gastric bypass if they are suffering from obesity-related health conditions such as diabetes or high blood pressure. Your surgeon will also recommend blood tests, diabetes glucose testing, urinalysis and heart check-ups before scheduling your gastric bypass surgery.

What are the risks?

The bypass is very powerful, and as with any powerful treatment it should be treated as such. Anyone who chooses to undergo a gastric bypass should be prepared to take vitamins and certain supplements for the rest of their lives. It sounds pretty basic, but failure to do so can lead to severe consequences. To monitor a patient's health after bypass we order blood work once or twice a year. Also, the gastric bypass will make it difficult for a person to digest sugar because of "dumping.”

What is "dumping?"

"Dumping" is a combination of side effects that occur in gastric bypass patients who ingest sugar. I prefer calling this process a "sugar allergy.” The reason behind dumping is that sugar is digested in the stomach. The smaller the stomach, the less sugar can be digested. In gastric bypass patients the stomach is made very small--the size of a shot glass. Because of the small stomach, gastric bypass surgery patients are not able to digest sugar. The undigested sugar can then be "dumped" into the intestine, which is ill-equipped to process it. As a result, there is a massive shift of fluid in the intestine, resulting in nausea, lightheadedness and diarrhea. These symptoms can last for 1-2 hours after eating sugary meals. In some cases, a dumping episode can last longer. While dumping is not harmful, it can be unpleasant. NJ Patients are encouraged to follow a strict gastric bypass diet to avoid dumping.

Is it possible to lose too much weight after gastric bypass?

Absolutely. Because the gastric bypass is very powerful it can cause malnutrition and a vitamin deficiency if patients are not following their prescribed diet carefully. Because the absorption of calories is significantly reduced, the foods consumed after gastric bypass have to have good nutritional value. If patients eat junk food, they will not get adequate nutrition and their body will eventually starve. In addition, after a New Jersey gastric bypass, patients must take vitamins and iron supplements daily and weekly to keep up with their body requirements. This is very easy to do, but diligence is required.

We recommend one multivitamin tablet daily, plus one tablet of B complex. Iron should be taken at least 2-3 times a week, especially in women, and vitamin D should be taken weekly.


Life after Gastric Bypass

Patients after gastric bypass surgery in NJ should have blood work at least once a year, which should include levels of vitamin B1, B3, B6, B12, A, E, D and Folate as well as CBC, iron profile, Ferritin levels, albumin levels and PTH. Electrolytes should be checked via CMP as well as levels of Zinc and Copper. Your vitamin intake can be adjusted based upon your blood work results.

Bypass patients have to follow a certain recommended diet, a sample of which can be found here. The procedure of the gastric bypass is carefully tested upon completion to ensure that there is no leak.


What Will the Gastric Bypass Cost?

Gastric bypass surgery is typically covered by insurance, if you qualify. For patients without insurance coverage, the fee is approximately $19,000. Gastric bypass surgery has to be done at a hospital and therefore is more costly than the gastric sleeve.

The CPT code for gastric bypass is 43644.
