Weight-Loss Surgery May Release Toxic Compounds From Fat Into the Bloodstream – Surgery

I’m not a doctor, just a guy who writes a blog on trying to live healthy by getting enough exercise and eating intelligently. So, I find the conclusion of this study to be almost karmic.

Toxic man-made chemicals—such as polychlorinated biphenyls and organochlorine pesticides—that are absorbed into the body and stored in fat may be released into the bloodstream during the rapid fat loss that follows bariatric surgery, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health. The finding points to the need for further research to understand the health effects of this potential toxicant exposure.

For the study, published online November 5 in Obesity, the researchers examined 26 people undergoing bariatric weight-loss surgery, and found evidence of post-surgery rises in the bloodstream levels of environmental toxicants that are known to be stored long term in fat, including PCBs, organochlorine pesticides, and PCB-like polybrominated diphenyl ethers. The study also revealed that participants born before 1976—when most of these chemical compounds were still widely used—tended to have much higher bloodstream levels of the chemicals, compared to younger participants.

“The fact that this increasingly popular type of surgery may be causing these compounds to be released into the bloodstream really challenges us to understand the potential health consequences,” says study senior author John Groopman, PhD, the Edyth H. Schoenrich Professor in Preventive Medicine at the Bloomberg School.

About 16 million people in the U.S. are morbidly obese, defined as having a body mass index (BMI) of 35 kg/m2. Their extreme overweight condition confers a relatively high risk of type 2 diabetes, cardiovascular disease, hypertension, and many cancers. For almost three decades, the U.S. National Institutes of Health has recommended weight-loss surgeries called bariatric surgeries—including stomach stapling and gastric bypass procedures—for people who are morbidly obese and have serious obesity-related conditions such as diabetes, as well as for anyone with a BMI over 40. More than 200,000 bariatric surgeries are now performed in the country every year. Continue reading

Some Facts About Weight Loss That Work

Since eating temptations abound around Valentine’s Day, I thought I would share these observations on weight.

“…. There are facts about obesity of which we may be reasonably certain — facts that are useful today,” says researcher Krista Casazza, PhD, RD, from the department of nutrition sciences at the University of Alabama at Birmingham, in a prepared statement, WebMD reported.

Here they are:

1. “Your genes are not your destiny. Moderate environmental changes can promote as much weight loss as even the best weight-loss drugs.”

I love this one. So often people use ‘bad genes’ as an excuse for their weight problems, ignoring completely their own bad eating habits.

2.”Even without weight loss, physical activity improves health.”

Another winner. I have reiterated this statement in at least 25 different posts on this blog. Eat less; move more; live longer.

UNCLE-SAM-EXERCISE
3. “Physical activity or exercise in the right amounts does help people lose weight.”

Amen. Listen to Uncle Sam.

4. “Continuation of conditions that promote weight loss helps people keep the weight off. Think of obesity as a chronic condition.”

Likewise, I think of good eating and exercise habits as chronic, too.

5. “For overweight children, involving the family and home environment in weight-loss efforts is ideal.”

6. “Providing actual meals or meal replacements works better for weight loss than does general advice about food choices.”

Both 5 and 6 sound like first rate advice.

7. “Weight-loss drugs can help some people lose weight.”

I am not going to argue with the experts here, but I sincerely doubt that the weight stays off if they don’t change their eating and exercise habits. I repeat my recommendation to pay attention to what you eat and exercise regularly. That will melt the pounds away. You won’t need drugs.

8. “Bariatric surgery can help achieve long-term weight loss in some people.”

The study was supported in part by the National Institutes of Health. Our tax dollars at work.

I would like to say for the record that I don’t believe losing weight works. It is only temporary at best. If, instead, you get your head on straight and aim to live a healthy life by eating intelligently and exercising regularly, I can promise that you will never have a weight problem.
