I came across an interesting weight loss invention this weekend that proposes to allow people to have their cake and eat it too. Scientists have constructed a kind of plastic intestinal condom to block digestion of food. Since gastric bypass surgery essentially reduces food absorption while decreasing stomach size, this removable plastic lining could act as a sort of non-invasive alternative to such a permanent procedure. Sounds intriguing?
Well, before we get our hopes up, it’s always best to check with the gastroenterologists. I dropped Dr. Brian Fennerty a note to ask him what he thought of this proposed weight loss solution. His response was enlightening – “The Endobarrier Gastrointestinal Liner is potentially very dangerous as it may block the pancreatic duct and cause pancreatitis, dislodge resulting in bowel obstruction, or ulcerate. There are no comparative trials and as such I would consider it investigational at best.”
Why is blocking the pancreatic duct scary? The pancreas is a little organ that should get a lot more respect, in my opinion. It produces enzymes that are secreted into the intestine to break down food – I like to think of the pancreas as a bag that contains acid as strong as Alien blood (those of you who’ve seen the movie will get that reference). Basically, the pancreas can liquify a steak – so plugging up the exit route for those enzymes is a really bad idea. You can imagine why pancreatitis is so painful.
And then there’s the risk of the liner getting loose and wadding up in a plastic ball and blocking your bowels, or the risk of the plastic irritating the intestinal lining and causing an ulcer which could bore a hole straight through your gut.
Well, I don’t mean to resort to scare tactics here… but honestly, this procedure has serious risks that one doesn’t really get from the media’s article on the subject, “New Procedure Could Help Millions.” So be careful out there folks – always check with your doctor before you try something new to lose weight. I’m afraid that diet and exercise are really the safest options out there.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

There is a new diet pill undergoing testing in Italy. The pill expands in your stomach, suppressing
appetite by giving you a false sense of fullness, sort of like those dehydrated
sponges that expand dramatically when you get them wet.
On the surface it sounds as if this pill might be a
reasonable approach – but there are 2 big problems:
- This
method (filling the stomach to give a sense of fullness and reduce eating)
has been tried before and has failed to produce the desired result. Back in the 1980’s scientists attempted
to use an inflated stomach balloon (Garren Bubble) to suppress hunger. Unfortunately it didn’t work, and put
people at high risk for gastric ulcers and other dangerous side
effects.
- There
is a serious risk of bowel obstruction with this pill. Once the tablet dissolves in stomach
acid, the cellulose condenses to produce a bezoar (rock like substance)…
the pill’s contents can then become wadded up like a rubber tennis ball
and not pass through the gut safely.
In fact, the pill could cause a fatal obstruction.
So, as we continue on our quest for the magic pill to cure
our obesity epidemic – we must reject yet another valiant effort. Sorry folks, it’s back to good old diet and
exercise for most of us.
*Many thanks to Dr. Brian Fennerty who discussed this pill’s
safety with me in a recent interview.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

Well, having grown up on a yogurt farm – nothing delights me more than scientific evidence that this fine dairy treat is good for your health. Hats off to my friends at the Imperial College, London who just published a study showing that elderly, hospitalized individuals may use yogurt to avert nasty bacterial infections that cause explosive diarrhea.
Yes, it’s the battle of the bugs at its best – the most common yogurt bacteria: Lactobacillus casei, L. bulgaricus, and Streptococcus thermophilus work together as pretty effective colonic bouncers for enemy bug C. difficile. In this study, elderly patients (n=57) at risk for hospital acquired diarrhea (due to antibiotic use) were given 2 small active culture yogurt drinks/day during the time they received antibiotics and for one week afterwards. Another group (n=56) was given similar drinks, but the yogurt cultures had been sterilized with heat (so there were no actual live bacteria in the yogurt).
And guess what? None of the patients who drank the live yogurt got C. difficile infections, while 9 in the other group did! That means that for every 5 elderly people in the hospital (and taking antibiotics) you could potentially save one from getting a painful gut infection.
So if grandma’s in the hospital on antibiotics, you might want to ask her doctor if she can eat yogurt. It may make the difference between a short stay and a long and unpleasant healthcare experience.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

I’ve been meaning to write about what happened at the
Gluten-Free Cooking Spree event that I attended last week… it was a pretty
funny story.
Gastro Girl and I were invited to a cook off for celiac
awareness – we were told that we would be helping a chef to create a gluten
free entrée on a stage in front of a large audience with CNN’s Heidi Collins
presiding. There were 7 teams consisting of a chef, a doctor and a reporter. It
sounded like Iron Chef (with a hint of “Scrubs” since I was cooking). On the debriefing phone call we were told
that our chef would be provided with all the necessary ingredients (thanks to
Wegman’s sponsorship) and that we only needed to show up 30 minutes prior and
take instructions from our chef. We had
1 hour to prepare the entrée and our meal would be judged against 6 other teams…
Sounds easy enough… but wait till you hear what really went
down. First of all, much to the surprise
and amazement of Gastro Girl and me, all the other teams brought sous chefs
from their respective restaurants to the cook off. Not only that, but they had cooked and
prepared most of their meal in advance, and were using the kitchen time to mix
and heat things. They were dressed
impeccably in white cooking smocks and hamming it up for the CNN camera crew. Our poor chef, Chef “Rock” (Rahman Harper)
from B. Smith’s Restaurant, got caught in some heavy DC traffic (this happens
when a motorcade of some ilk appears out of nowhere) and arrived about forty
minutes late.
Now, far from being an Iron Chef TV set, our facility was
actually a real hotel kitchen – steamy hot, grease covered tile floor, one
industrial gas stove, and stainless steel pots and pans hanging on wires
dangling above metal tables. Gastro Girl
and I had come straight from work, and were wearing business attire, with heals
and the whole bit. As I slid my way to
an unclaimed table, trying not to fall down in the grease in front of the CNN
cameras, I put my head together with Gastro Girl about how we could at least
find all our ingredients and have them ready for Chef Rock when he appeared.
We were the last team to arrive in the kitchen, and all the
ingredients had been handed out to the different teams… a box of groceries was
left for us in the walk-in cooler. As we
removed all the items we realized that many of our ingredients were missing (we
were planning to make cheese grits and a sort of spicy shrimp Jambalaya). In fact, there were only 2 cups of shrimp
(frozen and unpeeled!) in our box… and we were supposed to be cooking for 50
people… near our table was a group of sous chefs from a competing team, with a
large bucket of shrimp, grinning from ear-to-ear as they watched Gastro Girl
and me talking about our predicament.
Our situation was not lost on the organizers, however, and a
very kind lady asked us to give her a list of our missing ingredients so that
she could send someone to buy them for us.
Chef Rock appeared, and allayed our fears – “we can make this work, even
if we need to change the recipe a bit.”
Well, the other teams took up most of the burners on the
stove, and we had to wait until the last minute to cook our shrimp… and with 30
seconds to spare, Chef Rock came through with a gorgeous dish of soul food that
was whisked away to a large judge’s table in a crowd of hundreds. Gastro Girl and I wiped the nervous sweat
from our brow and followed him out to the booth we had in the ballroom.
There were several presentations made, with introductions of
the various teams (Gastro Girl and I shouted “wooo-hooo” when our team was
announced, and waved to the crowd – we had the best team spirit)… and finally
the winner was announced… it wasn’t our dish unfortunately (coriander crusted
skate won), but several members of the crowd told me that they liked ours best.
And so, the Gluten-Free Cooking Spree was a great success,
raising money and awareness for celiac disease.
The chaos behind the scenes went unnoticed by the participants, and I
felt proud of our little team – having pulled off a near miracle against all
odds.
Next year, we’ll be back with a vengeance… Watch out, sly
competitors – Dr. Val, Gastro Girl, and The Rock will be armed and dangerous!
