Gastric Bypass is a medical procedure where the stomach is made smaller to accommodate less food, causing extreme weight loss. This procedure is currently limited to the morbidly obese (equaling a BMI index of 40.0 or more) with a long history of obesity, usually equating 5 years or more. Other factors, such as dietary lifestyle, pre-existing conditions and issues with psychiatric disorders also play a part in determining the right Gastric Bypass patient. The effects of Gastric Bypass are heavily documented, and this procedure has its benefits and its risks which each patient should consider with their doctor. This procedure is only intended for the morbidly obese, and unless dieters need to lose the weight for their health (or if their weight is threatening their livelihood), this procedure is rarely recommended.

If diet and exercise have not helped you lose enough weight, bringing up Gastric Bypass with your physician may be one solution to consider although weighing the benefits against its risks is suggested before considering this risky operation. The cost (this procedure is not cheap either, and sometimes not covered by insurance) is also another factor, and the long recovery time may cause you to think twice before going under the knife.

Product Features

Gastric Bypass is completed by surgically placing a band around the stomach to make it smaller, then connecting it to the small intestine to further prevent more weight gain. This usually requires a week’s stay at the hospital, followed up by home bed rest and then slowly introducing food into the diet to avoid any complications. Complications include quick emptying of the bowels, vomiting, and faintness. If the procedure is successful, a weight loss of over 50% is usually predicted within the first year, although it will vary on an individual basis. It almost always causes a significant weight loss after successful Gastric Bypass surgery. Patients will need to follow a strict diet plan with a nutritionist to keep the procedure from failing, however, and to stay healthy. Nearly 30% of patients suffer from anemia and malnutrition due to the intestine’s decreased ability to absorb nutrients, and normally shots or vitamins are prescribed to tackle this issue.

Other issues following Gastric Bypass range from moderate to severe, the most severe being death. About 1.5% of patients die as a result of Gastric Bypass surgery, and about 15% will develop serious stomach-related issues such as ulcers or hernias. Other issues include an increased risk of gallstones, malnutrition, and bloating. Gastric Bypass is a lifelong, permanent procedure, and for those willing to take the risk, it may be one option to consider with your doctor. It is important to be aware of the dangers, however.

Gastric Bypass is the choice of many morbidly obese patients who need to lose the weight for their health, and it is heavily documented as a viable, working solution. There are serious risks when completing this procedure, however, and it cannot be reversed. Dedication is heavily required if one is to consider this procedure, and physicians will ultimately decide if this is the proper procedure for them.

    I had weight loss surgery in 08. Lost 150 lbs but still have about 120 to go. Have been stalled since 8 months out. what are the options or other procedures that can be helpful to start the loss again. frustrated doesn’t say it all.



    I pray your surgery went well mine was text book perfect. Now I fear for my life. 3 friend died within 2 years. No doctor will ever touch you if God forbids something goes wrong. Surgeons blame you for failure cold and illusive. Strongly advise against this.

    I was weighing 468 pounds before finally deciding to do something to help me. After losing right at 100 pounds throuise and training at a local gym, I had the gastric bypass in May 2007. I got down to 186 pounds about 2 years ago. Due to some other health issues I gained back up to my current weight of 225. I am 6 ft. so I carry the weight well. My biggest problem is the left behind flab on my stomach. I try hard to tone it up with no avail, and I would love some new diet suggestions. Thank you and YES>>>I would do it again! This was the best decision I’ve ever made.

    I had bypass surgery, and I only lost 100 lbs and began to be constipated, and am now gaining weight back. Is there any body else that had this happen? And is there anything i can do now?

    Regaining weight is common after gastric bypass. For example, a study in Utah found a 34% failure rate in patients with a BMI over 34 i.e. regained all or most of the weight. Other studies up to 12 years have found most patients to be an average BMI of 35 which is close to Regaining weight is common after gastric bypass. For example, a study in Utah found a 34% failure rate in patients with a BMI over 34 i.e. regained all or most of the weight. Other studies up to 12 years have found most patients to be an average BMI of 35 which is close to clinically obese. From all the research we have, it’s not an effective solution and the long term risks make it questionable as a viable solution.

    *** Yet fewer than 10 percent of patients achieve a normal BMI of 18.5 to 24.9 [with gastric bypass]
    Lee Kaplan, M.D., director of the Massachusetts General Hospital Weight Center in Boston ***

    *** “Because it’s risky, it’s only appropriate for a tiny fraction of people with obesity—the sickest 1 to 2 percent. The idea that all obese people should get [WLS] surgery is insane.”
    Lee Kaplan, M.D., director of the Massachusetts General Hospital Weight Center in Boston in “Self MAGAZINE: ‘The Miracle Weight Loss that isn’t’ AUG 2008 ***

    Dr Edward Mason (inventor of the gastric bypass after his 15 year followup): “For the vast majority of patients today, there is no operation that will control weight to a “normal” level without introducing risks and side effects that over a lifetime may raise questions about its use for surgical treatment of obesity.”

    I am going to have bypass surgery on Tuesday. I have been fasting since last Friday. I got REALLY, REALLY hungry today and I ate something. A lot of something really. Am I going to die on the table while having surgery?
