In Britain, the National Health Service used to pay for gastric bypass for individuals with BMIs greater than 35, but a new rule has raised the qualifying BMI to 45 and above. So many people were having gastric bypass, that it was overburdening the system. In response, some people are trying to gain weight to qualify for the surgery!
Here’s what a couple of British folk have to say:
“It’s grossly unfair and incredibly short-sighted. There are hundreds of other people like me who can’t afford private surgery, and the message seems to be pay up or pig out.”
“Instead of surgery and rehabilitation my only option is McDonalds and ice cream”This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

Just when you thought being super thin was best for your health… the Mayo Clinic published a short news brief in their December newsletter, “Mayo Clinic Connection” that casts some doubt on the benefits of being thin:
“Whereas obesity is a strong risk factor for heart disease, the standard test for measuring obesity – Body Mass Index (BMI) – may be of little use in predicting the risk of death. Results from studies involving 250,000 heart patients showed that those with the lowest BMIs had the highest risk of death. People who were overweight – but not obese – had a lower risk.”
Having a low amount of body fat has its advantages (like for rock climbing or marathon running) but being ~10 pounds overweight may actually be advantageous for your heart health. This is not an invitation to gain weight – just a little encouragement that “pleasantly plump” is not always such a bad thing. At least, that’s what I tell myself!

I’d never really thought about this issue until I read a study from the American Family Physician where some hardy souls sifted through the world literature for the answer to this very question. Their conclusion was that one out of every 220 women experiencing post coital bleeding has invasive cervical cancer.
The general prevalence of cervical cancer (in the US) is about 10 in 100,000.
So, if you’re experiencing bleeding after sexual intercourse, you should follow up with your Ob/Gyn to determine the cause. Also, regular pap smears are important in sexually active women as most cases of cervical cancer have no symptoms at all.
(How common is post-coital bleeding? About 1% of women report this problem.)

Complementary and alternative medicine (CAM) is important and popular, but ignorance about its potential harms can be dangerous to consumers. Physician passivity about the subject may also be doing consumers a disservice. Two interesting articles underscore this:
From the NIH:
In spite of the high use of complementary and alternative medicine (CAM) among people age 50 or older, 69 percent of those who use CAM do not talk to their doctors about it…
A telephone survey, administered to a nationally representative group of 1,559 people age 50 or older, revealed some reasons why doctor-patient dialogue is lacking. Respondents most often did not discuss their CAM use with doctors because the physicians never asked (42 percent); they did not know that they should (30 percent); or there was not enough time during the office visit (19 percent).
From MSNBC:
If you’re banking on a daily vitamin to make up for any deficiencies in your diet, you may be getting a whole lot more — or less — than you bargained for.
Of 21 brands of multivitamins on the market in the United States and Canada selected by ConsumerLab.com and tested by independent laboratories, just 10 met the stated claims on their labels or satisfied other quality standards.
Most worrisome, according to ConsumerLab.com president Dr. Tod Cooperman, is that one product, The Vitamin Shoppe Multivitamins Especially for Women, was contaminated with lead.
The same product also contained just 54 percent of the 200 milligrams of calcium stated on the label.
The analysis also showed that Hero Nutritionals Yummi Bears, a multivitamin for children, had 216 percent of the labeled amount of vitamin A in the retinol form, delivering 5,400 International Units (IU) in a daily serving. That’s substantially more than the upper tolerable level set by the Institute of Medicine of 2,000 IU for kids ages 1 to 3 and 3,000 IU for those 4 to 8.
Because too much vitamin A can cause bone weakening and liver abnormalities, the Yummi Bears “could be potentially doing more harm than good,” Cooperman said. “Vitamin A is one of those vitamins where you really don’t want to get too much.”
It’s important for physicians to educate themselves about CAM therapies and make it a part of their practice to ask their patients about the supplements they take. The Natural Standard databases are a great resource for physicians and consumers, and will be available soon at Revolution Health. Natural Standard, initially created by a team of Harvard physicians, systematically reviews the evidence behind the efficacy claims of various herbal remedies and supplements.
What resources do you use to evaluate the safety and efficacy of the herbs and supplements you’re taking?

In 1918, a man died of a vicious strain of “Spanish Flu” and was buried in the Alaskan tundra. Almost a century later, scientists found his well preserved body poking through some permafrost and decided to take tissue samples to a Canadian laboratory to thaw out the virus that killed the man.
Sounds like the beginning of a made-for-TV, horror movie, doesn’t it? Well, I wish it were fiction. This is a true story.
So why did the scientists revive this infectious menace? To see what it would do to modern day macaque monkeys, of course.
The BBC news reports:
“Symptoms appeared within 24 hours of exposure to the virus, and the subsequent destruction of lung tissue was so widespread that, had the monkeys not been put to sleep a few days later, they would literally have drowned in their own blood.”
Um… gross?
The scientists say,
“This research provides an important piece in the puzzle of the 1918 virus, helping us to better understand influenza viruses and their potential to cause pandemics.”
The BBC continues:
“Analysis at the University of Wisconsin-Madison (UW-M) revealed that a key component of the immune system, a gene called RIG-1 appeared to be involved.
Levels of the protein produced by the gene were lower in tissue infected with the 1918 virus, suggesting it had a method of switching it off, causing immune defenses to run wild. This ability to alter the body’s immune response is shared with the most recent candidate for mutation into a pandemic strain, the H5N1 avian flu.”
There is a final word from Dr. Jim Robertson, a British virologist:
“Many influenza virologists remain nervous about creating and experimenting with a reconstructed 1918 Spanish flu virus.”
Yeah, I’m nervous too.
