An Exploration of the causes and effects of obesity
Obesity is excess body fat. It is usually defined by body mass index (BMI) which is individual’s weight (kg) divided by their squares of height (m) (Jebb, 2004; Eagle et al, 2004). At the same time, BMI was classified into four conditions. Firstly, when the BMI less than 18.5 kg/㎡is underweight. Secondly, 18.5 kg/㎡to less than 25.0 kg/㎡ belong to normal weight. Thirdly, overweight is 25.0 kg/㎡to less than 30.0 kg/㎡. Finally, exceeding 30.0 kg/㎡ is totally obese (Eagle et al, 2004). Other papers categorize more detailed in the part of obese, which sections three parts, such as, Grade I obesity (30.0 kg/㎡to less than 35.0 kg/㎡), Grade II obesity (35.0 kg/㎡to less than 40.0 kg/㎡) ,

Jebb (2004) states that ‘It effects include metabolic syndrome (type 2 diabetes, hypertension and hyperlipidemia), and mechanical disorders (e.g. osteoarthritis, respiratory problems, sleep apnoea) and psychosocial disorders’ (Jebb, 2004). Other scholar has a similar view that it is a significant problem that obesity is not only one of the endocrine-metabolic conditions but also is a beginning of a series of diseases including type 2 diabetes mellitus, cardiovascular diseases, metabolic syndrome and some types of cancer in public health (Jiménez, 2011). Let us detail that those relationships between obesity and the following diseases.
Firstly, there is an extremely close relationship of type 2 diabetes and obesity. Diabetes belongs to metabolic syndrome, which causes the factors of atherosclerotic disease (Jebb, 2004). Further, the development and severity of this kind of disease is depending on weight increase (ibid), thus obesity is an important element factor. For example, women whose BMI is 25 kg/㎡ lead to the probability of diabetes is just five-fold, if the BMI is over 35 kg/㎡, the probability will increased to more than 40-fold (Jebb, 2004). Furthermore, the probability of diabetes still depends on different body shapes, such as, apple-shaped, pear-shaped, if women have a similar BMI. Jebb found apple-shaped women who have a large waist are higher diabetes risk than pear-shaped women who have excess fat on the thighs and hips (Jebb, 2004).
Secondly,
According to the Endocrine Society webpage, obesity is an enormous concern in the United States and it is related with diseases such as heart disease, diabetes, and hypertension. People with obesity have a higher risk of suffering a heart attack, abrupt cardiac death, angina, and cardiac arrhythmia than those that have a healthy body. Fat accumulation promotes higher levels of triglycerides and bad-cholesterol, and reduces the level of good cholesterol. Other potential health problems for obese people could be a stroke incident or renal failure. In the same way, overweight is a characteristic of young women diagnosed with Polycystic Ovary Syndrome, hormonal dysfunction, and infertility. Furthermore, most of the people with diabetes (Type 2) are obese. The National Health and Nutrition
In order to identify a condition as a disease, it should fit certain criteria. One of the reasons that obesity is classified as a disease is because of its large comorbidity. Obesity is a risk factor for chronic diseases such as hypertension, dyslipidaemia, type 2 diabetes, cardiovascular disease, sleep apnoea, musculoskeletal disorders and some cancers (Rossner, 2002). According to Rossner (2002), the death rate from all causes, cardiovascular disease, cancer and other diseases increases among moderate and severe overweight men and women in all age groups. Therefore, obesity is
The pathophysiology of obesity is when there is a buildup of excess body fat. This excess body fat is determined by calculating a person body mass index (BMI). The BMI is calculated by an individual’s weight in kilograms divided by the square of a person’s height in metersthis allows us to come up with appropriate range of weight to an individual’s height. The body mass index is used to find out if an individual is overweight or obese. Individuals who’s BMI that have a range of 25 to 29.99 are thought to be pre- obese and overweight When an individual body mass index has surpassed 30kg this person is considered obese. As an individual’sBMI increases they become part of a different class of obesity there’s class I which is 30-34.9, class II
Within the last half century, the obesity rate in America has increased by twenty one percent from thirteen percent to thirty four percent of adults; while the percent of the population considered overweight has remained stagnate at thirty-four percent. Unfortunately, the increase in the obese population poses a large threat to the health and well-being of United States citizens. Obesity is not only an accumulation of fat mass, but has been linked to many diseases such as cancer, cardiovascular disease, and diabetes. The strain that each of these respective diseases contributes onto the United States healthcare system is great, but how exactly does obesity contribute to the occurrence of these three diseases? What health factors are affected by obesity and lead to the development of chronic illness?
indicate that inherited genetic variation is an important risk factor for obesity. It was also pointed
This book comprehensively addresses the subject of obesity. Apart from highlighting the main causes of the epidemic, the book also presents suggestions on what can be done to stem the rising rates of obesity.
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).
Obesity basically means having too much body fat. Not being overweight for your height, having too much muscle, or water in your body. What exactly is obesity? “Obesity is a condition that is associated with having an excess of body fat, defined by genetic and environmental factors that are difficult to control when dieting. Obesity is classified as having a Body Mass Index (BMI) of 30 or greater. BMI is a tool used to measure obesity. Obesity increases your risk of developing related conditions such as diabetes, hypertension and sleep apnea, to name a few. Many individuals are affected by obesity and are not aware of it” (O.A.C, 2016). Causes of obesity vary from person to person, but most are from the same reasons. Taking in more calories than your body can burn leads to obesity because your body stores the unused calories as fat. Typical causes are eating too much food than your body can use, drinking too much alcohol, and not getting enough exercise. Many obese people who lose large amounts of weight and gain it back think it is their fault. They blame themselves for not having the willpower to keep the weight off. Many people regain more weight than they lost. Today, we know that biology is a big reason why some people cannot keep the weight off. Some people who live in the same place and eat the same foods become obese, while others do not. Our bodies have a complex system to help keep our
Obesity is known to produce a number of stress and inflammation responses in the body that lead to the activation of the inflammatory signalling molecules, Jun NH2-terminal kinase (JNK) and inhibitory kB kinase (IKK). Activation of these pathways plays a key part in the development of insulin resistance followed by progression to diabetes as they greatly affect inflammatory responses, insulin signalling, and lipid and glucose homeostatis (Nakamura et al. 2014). For example, activating the JNK pathway leads to serine phosphorylation of insulin receptor substrate (IRS) proteins which results in inhibited insulin signalling and thus insulin resistance. Double-stranded RNA-dependent protein kinase (PKR) has recently been shown to control the JNK and other major inflammatory pathways, to directly inhibit insulin signalling, to be activated by fatty acids as well as endoplasmic reticulum (ER) stress, and to be necessary for the activity of inflammasomes (Nakamura et al. 2010; Komiya et al. 2010; Lu et al. 2012). Moreover, PKR has been found to be highly activated in obese people as well as mice with genetically and diet-induced obesity, especially in adipose and hepatic tissues (Boden et al. 2008; Nakamura et al. 2010; Carvalho-Filho et al. 2012). Finally, recent studies have found that PKR knockout obese mice were protected against both IR and obesity-triggered inflammation and that administration of PKR inhibitors reduced JNK activation, reduced inflammation in adipose
Obesity refers to the condition of having an extra amount of body fat. Obesity is caused by eating too much and moving too little. When an individual’s amount of body fat becomes too high, they are at a greater risk of being affected with life changing diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, and others. This shows that people should become more physically active and attempt to make healthier choices because their life depends on the decisions, they make.
The ease of slipping on a pair of jeans turns into a battle between a thigh and pant leg while exerting too much pressure on the diaphragm; a loss of breath incurs. How can obesity be defined? This can be described as a critical medical condition in which the body fat has been accumulated in an abnormal way especially in the abdominal area. To be considered obese, a person’s Body Mass Index (BMI) must be 30 or greater, and this measurement can be calculated by dividing the person’s height and weight. Without having the need to find data, just looking around, more people are becoming overweight or obese. Where one problem begins,
Obesity is the state of imbalance between the calories consumed versus the calories expended leading to an excessive fat accumulation in adipose tissue resulting in physical and psychological problems. The excess fat is distributed in the body either around the waist (abdominal fat), trunk (android store fat) or gynoid store fat in hips/thighs. The primary causes of obesity are inactivity, unhealthy diet and eating habits, genetics, unhealthy diet and lifestyle, certain medications like antidepressants, and diabetes medications, age, lack of sleep, and sometimes the result of quitting smoking. Even though obesity can sometimes be caused by medical conditions such as Prader-Willi syndrome, Crushing’s syndrome and other diseases or
Obesity in the United States has more than doubled over the past four decades. Prevalence of obesity cause many other disease such as diabetes and heart issues. Obesity can be described as a health condition of a person or people of a population that have excess body fat. Diabetes is a disease related to high level of blood sugar in the blood. Obesity and diabetes are among disease that have direct relationship with each other. As obesity increase in a population, diabetes increases too. Jennifer B.Marks, Professor of Medicine at the University of Miami Miller researches in “Obesity in America: it’s getting worse”, Roger Z. Joanne a public health provider in the Obesity Action Coalition group researches in “Obesity and type 2 Diabetes”, Eckel H. Robert, Professor of Medicine in Colorado University researches in “Obesity and Type 2 Diabetes: What can be Unified and What needs to Be Individualized”, and Obesity Society group researches in “Your weight and diabetes”, mention that while obesity and diabetes have different definition in medical process, the reason why people become obese and diabetic as well as how to prevent them is same. Eating larger portion size than what the body needs , lack of physical activity, and putting foods without good quality in diet are the major reasons that people become obese.
The epidemic of obesity is a medical circumstance defined as excess weight in the form of fat which may impair health. (World Obesity Federation, 2012). Obesity can be calculated by BMI which is body mass index. Obesity means BMI greater than 30. (ibid). This essay will outline the causes and effects of obesity. Diet, lifestyle, toxic environment and the causes of obesity are physical, psychological and economic are impacts.
