Decreased mortality with gastric bypass surgery

+1

Gastric bypass surgery will increase not decrease your life-span.  Morbid obese patients die 12 - 15 years earlier than normal weight persons.  Patient that undergo bariatric surgery decrease their 5 year mortality by up to 89%.  Weight loss surgery is the recommended treatment for patients that suffer from morbid obesity.  it decreases most of the medical problems related to obesity like diabetes and heart disease which results in decreased mortality.

Death rate significantly reduced AFTER Bariatric Surgery

+1

The answer is absolutely no. The largest study showing death rate after bariatric surgery was done in Sweden and was published a few years ago in the New England Journal of Medicine. They followed approximately 5,000 patients for 10.9 years and they had a 99.9% follow-up rate. Half of the patients had bariatric surgery and the other half were treated with conventional medical therapies for obesity (diet, exercise and behavior modification). The study showed that the patients who had bariatric surgery had a 29% decrease in their death rate over that ten year period. Bariatric surgery is not a detriment to your health whereas obesity is.

Nutritional deficiencies and vitamin deficiencies are usually very easily treated. Most bariatric surgeons will usually check vitamin levels every three months for the first year and yearly after that. If a vitamin deficiency is found, we treat it.

Risk of Gastric Bypass operations

I agree with Dr. Hess. In answering this question you need to be aware of a sample bias. The people who undergo weight reduction operations and especially the various subset of gastric bypass operations are ALREADY at a high risk of death from Diabetes, Blood pressure and heart disease as well several others. The operations are done to reduce their weight to reduce and remove as many of these factors as possible.

I KNOW from my bariatric surgery colleagues that they employ psychological screenings to make sure they operate on intelligent and motivated patients because strict compliance with doctor's orders, diet and supplements are very important. If patients choose NOT to follow these guidelines they will get into serious trouble BUT the operations are inherently safe and have saved millions of lives.

Gastric bypass death

 I am neither a bariatric surgeon nor a proponent of surgical weight loss, but a ten year mortality following this surgery is not the standard.  Unfortunately, some will never lose weight without the assistance of surgery.  There are nutritional deficiencies associated with this surgery, but they can be amended with supplements.  Sometimes the health benefits such as resolution of diabetes and improvement of osteoarthritis outweigh the risks.
