An epidemic is sweeping through the developed world, threatening millions with disability and death. Is it the dreaded Ebola virus? No, it is obesity. ‘Epidemic’ may sound exaggerated, but the facts speak for themselves: 154 million people worldwide are obese—or more than 20% are over their ideal body weight—including more than 50% of all Americans. More disturbing is the prevalence of childhood obesity, which has jumped dramatically over the past 20 years and now accounts for a doubling in the incidence of diabetes, a 5-fold increase in sleep apnoea and a 3-fold increase in gall bladder disease. The World Health Organization and the US Surgeon General have already warned that obesity is a serious, life-threatening disease. Indeed, as a major risk factor for hypertension, stroke, heart disease, diabetes and possibly certain forms of cancer, obesity exacts a greater toll on health and healthcare costs than either smoking or drinking. In the USA alone, the direct medical costs of obesity-related diseases account for 6% of the nation’s entire health-care budget. Obesity is, in short, a great deal more than a ‘lifestyle’ or cosmetic problem.
This has not been lost on the pharmaceutical industry. Companies know that the worldwide market for an effective treatment for obesity is gargantuan: analysts estimate that an effective and safe drug could generate as much as US$26 billion per year in the USA alone. ‘It is probably the largest pharmaceutical market ever, and carries with it 27–30 dangerous co-morbidities,’ said Louis Tartaglia, Vice President of metabolic diseases at Millennium Pharmaceuticals (Cambridge, MA), who estimates the current annual worldwide market conservatively at US$10–15 billion. If one adds the patients who are obese and diabetic, the number soars even higher, as obesity and diabetes are linked diseases.
The sudden rise in obesity is mainly a result of lifestyle changes, particularly the ready availability of calorie-laden, refined food and a decrease in physical activity. ‘Genes have not changed in the past 50 years, but our eating and exercising habits have,’ said George Yancopoulos, Chief Scientific Officer and President of Regeneron Pharmaceuticals (Tarrytown, NY), one of many companies working on drugs to treat obesity. But it cannot be lifestyle alone. Certain ethnic groups have a higher prevalence of obesity, and the discove...

Finally, older substances may yield new drugs as well: a small region of the human growth hormone appears to have a specific effect on fat without any effect on either growth or insulin resistance, according to Frank Ng of Monash University (Melbourne, Australia). With the support from Metabolic Pharmaceuticals, Ng has developed it into an orally administered drug, which is now in phase IIa testing.
Basic research to uncover fat metabolism and applied research to find effective treatments against obesity have received a lot of attention over the last years both in terms of media coverage and funding. And even if the interest in developing effective treatments against being overweight has a strong lifestyle component, it is increasingly crucial to public health. New treatments are needed to help those millions of people suffering from obesity—especially the dramatically rising number of overweight children who are at risk of lifelong diabetes and the accompanying risk of heart disease and disability.
Obesity is a very complex condition as there are many physiological and psychological dimensions to it. The complications accompanying the disease are multiple and are associated with the increased risk of many other medical conditions. It is thought that we live in an obesogenic environment due to an interaction of environmental, developmental and cultural influences. With the main cause of the disorder thought to be due to a combination of a sedentary lifestyle accompanied by an increased consumption of poor quality food with a high calorie and sugar content. The lack of energy expenditure could be explained by many individuals working a large number of hours, most days of the week in jobs that require minimal physical activity and it is often difficult to accomplish the recommended ...
Obesity remains an extremely serious issue worldwide. Once considered a problem for wealthier counties, overweight and obesity are now dramatically increasing in low and middle income countries (WHO, 2011). In American, the rates of obesity continue to soar. CDC (2009) recognizes obesity as a risk factor for diabetes, heart disease, high blood pressure, and other health problems. According to NHANES over two-thirds of the US are overweight or obese, and over one-third are obese (CDC, 2009). Treatment for this illness varies; it may include the incorporation of diet, exercise, behavior modification, medication, and surgery. Since there is no single cause of all overweight and obesity, there is no single way to prevent or treat overweight and obesity that will help everyone (CDC, 2009).

Obesity has been accepted in the American society as a norm. According to the U.S. office of the Surgeon General, in 1999, 6 in 10 American adults were classified as obese or overweight (McMurray, par. 5). In order for one to be classified as obese they’re body mass index (BMI) must be 30 or greater. The number of obese in America has continued to increase. It has been estimated by The World Health Organization that 300 million people will be obese by 2025 (Bailey 3). Since obesity comes with many health risks, many feel it should be treated as a disease.
Obese people account for thirty seven percent of the United States population, but obesity- related diseases such as diabetes and hypertension account for sixty one percent of healthcare costs in the United States every year. The costs increase to billions of dollars which puts a huge strain on not only the economy but healthcare also. Obesity is a big problem in America and everyone either knows someone who is overweight or they’re overweight themselves. Treatment for obesity is having an active lifestyle, weight loss medication, or weight loss surgery.
There is no doubt that obesity has taken its seat as one of the top disease that strikes the world today. In America, obesity has now spread through the country leaving 2 out of 3 adults either overweight or obese, and worldwide 1.5 billion are overweight or obese (Overweight). The cause of this disease stems from multiple reasons such as the increase in modern food production, putting out ample amounts of food causing the prices for meat, groceries, and especially junk food to plummet. Subsequently, Americans especially were more inclined to purchase more food and showed an increase in the average American house hold food intake by 1,000 more calories a day (Dreifus).
Obesity has increasingly become a significant public health concern in the United States. In the past four decades, the numbers of overweight children, adolescents, and adults has shot to high margins, and the rise cut cross all ages, races, and ethnicities for both males and females. A recent analysis by the National Health and Nutrition Examination Survey found that 30% of the American adult aged over the ages of twenty, which is a representation of over 60 million adults, was obese. Still the same survey indicated 16% of those between the ages of 16years and 19 years, which is over 9 million children and teenagers, were obese. This has come with its share of repe...

Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
As a health care professional it is our position statement that obesity should be considered as a disease. Overweight and obese adults are considered at risk for developing diseases such as type II diabetes, hypertension, high blood cholesterol, coronary heart disease, and certain type of cancers. An average of 300,000 deaths is associated with obesity and the total economic cost of obesity in U.S. was about $ 117 billion in 2000. As health care professionals it is our responsibility to increase public awareness of health consequences of over weight and obesity. Obesity as a disease: Obesity fits all the definitions of ‘disease’, that is, interruption in bodily function.
Millions of Americans and people worldwide are overweight or obese. Obesity develops when “calories consumed exceeds calories expended” (“Obesity and Genetics”). “Obesity rates have more than doubled in adults and children since the 1970’s,” and in the present day it is estimated that “two – thirds of U.S. adults are overweight or obese” (Ogden). Being overweight or obese highly increases the risk of deadly health problems, therefore this statistic states that the majority of the United States population is at risk of obtaining life–threatening diseases. Around forty years ago obesity would not effect this abundant number of people; however today’s society consumes more fast food in addition to spending most of their hours doing sedentary activities (Green). There are now many causes of obesity such as environment, genetics, bad habits, culture and economic level. Obesity has many negative impacts on the human body. It can very likely cause diabetes, joint pain, sleeping problems, depression, and many hazardous diseases (“Explore Overweight”). In contrast to this, there are some possible solutions to obesity such as physical activity, dieting, and surgery. Obesity is a widespread epidemic that unfavorably affects the body, but with exercise fused with dieting the disease could be kept to a minimum.
According to reports from the Centers for Disease Control, during the past thirty years the average rate of obesity in the US adult population has risen from under 20% to 35.7%. Secondly, during the same period, childhood obesity has tripled to a rate of 17%. It has been currently found that in more than a third of all children and adolescents are now considered to be overweight or obese. These shocking statistics show that a high prevalence of obesity appears to have increased significantly in the United States. It also continues to be a major public health concern, the total medical costs of obesity within the United States were estimated at $147 billion in 2008, and it is believed to continue to increase with the rising cost of health care. Secondly, obesity is also now considered to have become a global phenomenon. The World Health Organization has stated that obesity is responsible for approximately 8% of health costs in Europe and approximately over 10% of total deaths.
(Jonas Minet, Stephen morris 2010). The prevalence of obesity has increased more than twofold in the last 25 years. In 2014, world health organisation (WHO) estimates that 1.9 billions of world’s adult populations are overweight, of which at least 600 million were obese, representing 13% of adult’s population (obesity WHO, 2014). Obesity is no longer a rich country’s problem, but also affects the poor and emerging countries which make it a major public health challenge. ( )

Obesity is a physiological condition characterised by an excessive accumulation of body fat, specifically the build-up of adipose tissue beneath the skin. In recent years, the number of people diagnosed with clinical obesity has increased dramatically, with governments desperately trying to tackle the obesity epidemic and its associated consequences (McLannahan and Clifton, 2008). Studies have found that the prevalence of obesity once stood at an estimated 9.8% (Kelly, Yang, Chen, Reynolds & He, 2008), a considerable figure representing almost 400 million individuals worldwide. Even though obesity has now been recognised as a major problem the number of people affected is increasing rapidly, with almost 300,000 deaths attributable to obesity in the USA each year (Allison, Fontaine, Manson, Stevens, & VanItallie, 1999). Excessive amounts of fat can prove dangerous as the condition has a very high comorbidity rate with other long term health issues such as diabetes, cardiovascular disease, hypertension and cancer (Pi-Sunyer, 1993). Numerous examples of media, medical journals and educational literature concerning obesity refer to the condition as a disease, with an increasing use of the word ‘Epidemic’ to describe the somewhat recent surge of obesity cases in western societies (Boero, 2007), however there is little material available that offers evidence for obesity meeting specification for disease. Instead it has been proposed that obesity is alternatively a risk factor for developing other potentially harmful diseases, influenced by a variety of other factors i.e. genetics, cultural ideals and biological impairments.
