Guest Post: Fighting Fat with Drugs – Is it Worth It?

Wednesday, July 14th, 2010

It’s no longer a trivial issue over which kids get bullied in the school playground or which adults get teased about at the office; today, obesity is an epidemic of oversized proportions. It’s a chronic disease, one that 12 million Americans are suffering from, and because of this, illness is on the rise. Diabetes, heart disease, strokes, cancer, and various other diseases are on the prowl and sending healthcare costs shooting through the roof. And while anyone with plain common sense knows that the best and safest way to fight obesity is to eat a healthy diet and get regular exercise over the course of your life, most people tend to resort to shortcuts and seek remedy in anti-obesity drugs.

To be fair, some people do need extra help since diet and exercise alone cannot do much to help them reduce because they are abnormally obese. And so weight loss pills help them control and/or suppress their appetite or prevent their bodies from digesting the fat in the food they eat. But a recent study conducted by Brazilian and Canadian researchers and published in the British Medical Journal states that even the long term use of weight loss pills contributes only to a minor reduction in weight, an average of less than 11 pounds.

And when we take into consideration the number of side effects that these pills cause – the anti-obesity drug orlistat which is supposed to boost weight loss by preventing your body from digesting fats causes digestive side effects even as it promotes only an average weight loss of 7 pounds; sibutramine and rimonabant which suppress or interrupt neural signals to disguise hunger pangs and food cravings reduce weight by an average of 9 pounds, but at the cost of insomnia, high blood pressure, an elevated pulse rate, and nausea. Rimonabant has also been known to cause anxiety and depression and other mood disorders and is as of now not approved for sale by the FDA.

On the bright side however, the drugs did serve to improve cardiovascular health and prevent and/or control diabetes, hypertension, and cholesterol, the killer diseases that attack overweight people. But then again, with most weight loss drugs being available OTC, we must ask ourselves the question – is it ok to tempt and even court the disease just because we perceive that the cure is just a pill away? And are we fooling ourselves into believing that it is ok to be overweight because anti-obesity medicines are now available even without a prescription?

The truth cannot be written more clearly on the wall – we are a nation plagued by obesity; we invite disease with open arms because of our irresponsible lifestyles, a callous attitude towards exercise, and an overindulgence of food. And because of this, our healthcare costs are spiraling out of control. It’s time we stopped depending on pills and medicines as the panacea to cure all our ills and start looking at their source instead; it’s time we bring up our children to respect and safeguard their health instead of encouraging their sedentary lifestyles and feeding them with junk food; and it’s time we started giving good health the deference it deserves – we don’t have to place it on a pedestal, it’s enough that we acknowledge its importance in our lives.

Next generation cure for killer infections

Friday, July 31st, 2009

Another great talk at TED:

“Drug-resistant bacteria kills, even in top hospitals. But now tough infections like staph and anthrax may be in for a surprise. Nobel-winning chemist Kary Mullis, who watched a friend die when powerful antibiotics failed, unveils a radical new cure that shows extraordinary promise.”


The Definition of Pandemic

Monday, June 15th, 2009

Guest Post:

The word pandemic has been thrown around in recent years because of the prevalence of many major illnesses that have occurred throughout the third world nations as well as even many Western nations. However, the recent Swine Flu outbreak has caused much deliberation as to the proper terminology of the word itself.

There have been generations of widespread epidemics in the past that have included influenza, cholera, and a multitude of other diseases. However, the World Health Organization has come up with a six-tiered level in which to determine when to implement specific disease control efforts around the world, which has successfully led to many countries quarantining illnesses which could be easily spread abroad. However, the true definition of a pandemic is not delivered by the WHO nor can medical journals accurately define it as well. Rather, the general public is on its own to determine what a pandemic ensues, as it implies the “rapid spread of an infectious disease to many countries”. However, the severity of pandemics vary with each disease, and not every country is affected when an outbreak occurs.

Additionally, the variety of different illnesses affects the overall terminology of the word; scientists and doctors alike are still unsure as to how pandemics arise, how they spread, and why they vary in their lethality. The background of the originating country has a lot to do with the severity and contamination of the impending illness and helps contribute to the overall definition of a pandemic. The recent Swine Flu outbreak has increased concerns over the spread of a disease within these “Western nations” which otherwise were remarkably protected from threat of outside illnesses that could infiltrate these nations. The fact that the United States was one of the first countries to report signs of such a disease caused the WHO to scramble to upgrade their alert system in order to properly take care of this problem. It is unfortunate that it takes a Western nation to cause this much concern over an illness, while many African nations have been experiencing similar epidemics. The new limelight on these Western nations is solely due to the international trade that occurs within many of these nations, which therefore caused the disease to be spread throughout Europe, Asia, and Australia.

This new illness caused the WHO much stress as to a proper cure for the illness as well as a way in which to quarantine travelers from disease-ridden countries. While the illness can be treated with regular flu remedies, the fact that so many outside the tradition flu age group were coming down with the illness and succumbing to its side effects caused the WHO to take drastic measures and qualify it (perhaps prematurely) as a pandemic. This recent flu outbreak is vastly different from any earlier outbreaks which may be labeled as “true” pandemics, but this type of definition is forever changing and it may take another widespread illness before we can determine what is the proper scenario in which to classify as a pandemic.

Preventing the next pandemic

Tuesday, March 31st, 2009

“Using genetic sequencing, needle-haystack research, and dogged persistence, Nathan Wolfe has proven what was science-fiction conjecture only a few decades ago — not only do viruses jump from animals to humans, but they do so all the time. Along the way Wolfe has discovered several new viruses, and is poised to discover many more. His research may open the door before the next pandemic may happen.”

Watch this awesome presentation at TED 2009.

A related presentation was given by Joe DiRisi at TED 2006 in which he described a DNA Microarray test (Virochip) that can not only detect all viruses in one test but also has the capability (and technology) to detect relatively unknown viruses.
