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 …show more content…
Indeed, research on fat metabolism has made large strides forward over the last decade and has challenged some established views. ‘One of the most important advances in obesity research is the realisation that fat is an endocrine tissue,’ said Barbara Kahn, Professor of Endocrinology at Harvard University’s School of Medicine. Another step forward was the discovery of a number of peptides that function as central regulators of food intake and energy homeostasis. These findings point to a complex involvement of the neuroendocrine system, where the central nervous system and fat interact through hormones and neurotransmitters, and affect other organs, most notably the liver and the pancreas.
Given the complexity of this system, it is no surprise that most treatments have been relatively ineffective or fraught with serious health risks, such as addiction to amphetamine diet pills, heart valve damage and hypertension. Furthermore, only a few drugs have reached the market recently. Xenical (Orlistat), a pancreatic lipase inhibitor developed by Hoffmann-LaRoche (Geneva, Switzerland), works by blocking the absorption of fat in the intestine, but can cause uncomfortable side-effects and has been linked to an increased incidence of cancer. Meridia (known as Reductil in the UK), originally developed by Knoll AG (Ludwidgshafen, Germany), is a serotonin and norepinephrine reuptake inhibitor that is thought to act on the appetite centre of the hypothalamus.
An estimated 97 million adults in the United States are overweight or obese (Klein 2000). “"Affecting one in five Americans – or more than 22 percent of the U.S. population – obesity is one of the most pervasive health problems in our nation right now," said George L. Blackburn, M.D., Ph.D., associate professor of surgery and associate director of the Division of Nutrition at Harvard Medical School/Beth Israel Deaconess Hospital, Boston, Massachusetts. "We need to implement steps to slow the progression of this national epidemic” (NAASO 1999). But the problem of obesity does not only affect the United States. "We now know that the growing prevalence of obesity is creating major health problems worldwide," said Dr. James O. Hill, president of the North American Association for the Study of Obesity (NAASO) and Professor of Pediatrics and Medicine at the University of Colorado Health Sciences Center. Obesity was once regarded as unique to Americans, but it is now seen as a global health risk affecting developing and underdeveloped countries (AOA 2000). Obesity is increasing at an epidemic rate in the United States - 1.3% a year for women over 20. Rates of obesity among minority populations, including African-Americans and Hispanic Americans are especially high (AOA 2000). There is also a marked increase in obesity among children.
Obesity is an increasing issue in modern society. It has been deemed an ‘epidemic in the developed world’ and statistics (from Public Health England) show obesity in the United Kingdom has been on the rise for many years, with currently 61.9% of men and women being obese or overweight. In England alone, 1 in 4 adults (age 16 years or over) are currently obese – (25.6%) - placing more than half the adult population overweight or obese (HSE, 2014). This growing problem in developed countries is responsible for thousands of deaths each year due to a number of contributory factors.
“Obesity is a disease that affects more than one-third of the U.S adult population (approximately 78.6 million Americans). The number of Americans with obesity had steadily increase since 1960, a trend that has slowed down in recent years but show no sign of reversing”.
One in three Americans are at risk for more than 30 chronic illnesses due to obesity. It is the biggest driver of healthcare, costing the country millions of dollars each year. Poor eating habits are the main cause of this disease and could all be changed beginning with the youth of the nation. 20 million children under the age of five are now considered overweight or obese in America (Dyer). What was once a rare disease, has now become an epidemic. Few health topics have initiated as much debate and controversy as obesity has within the past 15 years. The hope of new treatments progresses as obesity becomes the norm of our society and continues to change America every day.
Obesity is a big problem in our world today. From the beginnings of 1970’s, America is known for the country on the fast track for being overweight. Obesity can cause health related issues among the people. From the early childhood onwards kids got attacked by the type II diabetes, cancer, high blood pressure and some other lifelong diseases.
Obesity has been measured or defined in various ways. Many researchers have differing opinions on the origins and effects of obesity. The rapidly increasing rates of obesity are often linked to a high calorie diet and little to no physical activity. Although obesity is seen as a disease that affects a person’s weight, it actually affects a lot more than that. Obesity can affect individuals in both adolescence and adulthood, their families, and the healthcare system. From an outside viewpoint, obesity looks like a disease that careless, inactive people develop. Not always is this the case. Obesity is not a disease that affects solely the weight of a person. To be considered obese, your BMI (body mass index) would have to be 30 or higher. Almost 70 percent of Americans are either overweight or obese. Not only does obesity affect the weight of a person, it can also lead to increased risk for diabetes, high blood pressure, heart disease, sleep apnea, and many other things. Questions posed on this dreadful disease by many people are on the origin of the disease, the effects and exponential growth of the disease, and the actions that are being taken to help provide a healthier environment for Americans and to establish programs and preventative methods across the country to help fight the ever increasing obesity rate.
The last decade has welcomed, with open arms, a new epidemic: obesity. Currently in the United States, more than one-third of adults, 35.7%, and approximately 17% of children and adolescents are obese. Obesity is not only a problem in the US but also worldwide with its prevalence doubling in high income and economically advanced countries and is also growing in under-developed areas. Its incidence rate is continually increasing with each successive generation and in each age group, including the elderly (Byles, 2009; Dorner and Rieder, 2011).
Obesity in the United States has been a serious problem affecting Americans and has been continually growing higher in numbers each year. American obesity has nearly doubled within the last 40 years and is now considered to be an epidemic that is affecting millions of people around the nation. According to the National institute of Diabetes and digestive and kidney Diseases, 31% of men and 35% of women are considered seriously overweight, along with 15% of children between the ages of six and nineteen are also overweight. The lack of physical inactivity and extreme poor dieting are catching up to almost the same threat as cigarettes and tobacco smoking. We as a nation are considered to be the fattest country in the world.
It is no surprise that obesity is becoming an increasingly prominent health concern. In fact, since 1980 global obesity has almost doubled. (1) “The percentage of children aged 6-11 years in the United States who were obese increased from 7% in 1980 to nearly 18% in 2012. Similarly, the percentage of adolescents aged 12-19 years who were obese increased from 5% to nearly 21% over the same period.” (2) “35% of adults aged 20 and over were overweight in 2008, and 11% were obese.” (1) To put these percentages into perspective, in 2008 the world population was at almost 7 billion, more than 1.4 billion adults, 20 and older, were overweight, roughly 500 million were obese. (1) Obesity can no longer simply be a concern; it is a
The childhood obesity plague in America is a nationwide health emergency. One in every three children (31.7%) ages 2-19 is overweight or obese. The life-threatening price of this epidemic makes a persuasive and serious call for action that cannot go unnoticed. Obesity is anticipated to cause 112,000 deaths per year in the United States, and one third of all kids born in the year 2000 are likely to develop diabetes at some stage in their lifetime. The present age group may even be on a pathway to have a shorter lifespan than their parents. There needs to be change so we don’t lose our children. Most people may not know that America is leading with the most childhood obesity issues. People that are obese are more likely to have risk factors such
America is facing a rigorous obesity plague that is endangering the health of millions. Moreover, we are passing our bad practices down to our children. Obesity is a stipulation in which anomalous or excessive fat buildup in adipose tissue that damages health. Obesity is defined in adults as a body mass index (BMI) exceeding 30 (kg/m). Obesity is one of the most discernible, but until recently, most deserted public health problems. The present high pervasiveness of obesity and the brisk increase in pervasiveness in the last twenty years has been referred to as an endemic (Johnson SJ, Birch LL. 1994). Children all through the U.S. are getting fatter and less fit, through potentially treacherous enduring consequences. The figure of
Obesity has become the silent killer in American society. It is a risk factor for numerous chronic diseases including the four leading causes of death. Obesity can be linked to stroke, heart disease, cancer and diabetes, all serious health problems that can be fatal. Obesity is linked to 300,000 deaths annually in the industrial world (Flamholz, 2001). Often in society and in the medical community there exists a lack of understanding that obesity is in fact a disease and needs attention, otherwise the rates of many diseases will continue to climb.
It was merely a decade ago that the obesity epidemic was thought to only be a minor problem and had only alarmed a small number of endocrinologists interested by the size of the situation (James, 2008). However today, the problem of obesity is vast with more awareness of its presence by doctors and individuals alike. In fact, the Center for Disease Control and Prevention states, “More than one-third (34.9% or 78.6 million) of U.S. adults are obese (CDC, 2014)”. These numbers are outrageous and eye opening, leaving millions looking for a solution to this troubling epidemic. Obesity is not simply a cosmetic flaw as some might think, but is actually a very dangerous state of being for any individual to sustain long-term. Mentioned further in
Two thirds of American adults are obese or overweight. Obesity is a silent killer that is taking over the United States slowly but surely. People do not typically realize how serious obesity is and it gets joked about, humiliating those who are affected. Obesity is not a joke, it is a disease that is killing everyone’s family, friends and neighbors. Obesity alone is detrimental to the health of an individual, it causes many adverse effects to the body that are often difficult to repair or cure.
Obesity is a condition in which the over accumulation of adipose fat tissue causes the weight of a person to increase abnormally. Their weight exceeds by 20%, as a factor of their ideal body weight. According to recent analysis, statistics show that more than one third of the world’s population is targeted by obesity. Research shows that overweight and obesity kills more people than underweight. Obesity occurs greatly amongst adults who are 18 years or older. An estimated 600 million adults were obese out of the 1.9 billion that were overweight, around the world in 2014. One in three adults in Mexico, New Zealand and United States are obese, and one in four adults in Australia, Canada, Chile and Hungary are obese. In contrast, rates of obesity are much lower in Asian countries, where approximately 2-4% of adults have obesity. In countries such as Mexico and the United States, Latino and Africans have the highest rates of obesity amongst all the individuals. However, along with adults, statistics show that the rates for obesity are also high among children within and below the age of 5. As calculated in 2013, the number of children across the world that were either overweight or obese was 42 million. Since then, the rates have increased by 30% more in in low- and middle-income countries than in developed countries. Due to the fact that this condition continues at higher rates across the world, several organizations, such as the World Health Organization, are working with and
