The Effect Of Obesity On The Cardiovascular System

Candidate genes allow researchers to come up with rational hypothesis of role of these genes and their contribution to different conditions, in this case obesity. Therefore, they are potential predisposition factors. Candidate genes are chosen on a basis of knowledge of their function, biochemistry and their expression pattern (what protein they encode for and where is this protein mainly expressed) in obesity. At present, there are about 300 genes that have been hypothesized to contribute (to some extent) to obesity development.

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

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

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

Cardiovascular disease is any disease that relates to structural compromises or an obstruction of the blood vessels. Two of the most common types of cardiovascular disease involve obstructions of the arteries or the thinning of the arteries causing an increase in blood pressure. According to the American Heart Association’s article, a 14 year study found that a body mass index of twenty three to twenty five showed an increase in coronary heart disease of fifty percent. Also men from the ages of forty to sixty five with a body mass index of twenty five to twenty nine showed an increase of seventy five percent in risk for coronary heart disease. With increased weight comes

We all know someone who has suffered from heart disease. Whether it was from a heart attack, congestive heart failure, or stroke, some type of cardiovascular disease has taken the life of someone we loved way too soon. This epidemic of heart disease must be stopped through the collaboration of physicians, nurses, law makers, and concerned citizens. The purpose of this paper is to examine cardiovascular disease, the risks associated with heart disease and obesity per Milo’s framework, comparison of obesity and Healthy People 2020 national goals, and finally the long-term and short-term goals and interventions selected for this paper.

Obesity increases the risk of several debilitating, and deadly diseases, including diabetes, heart disease, and some cancers. The condition most strongly influenced by body weight is type 2 diabetes Fat cells, especially those stored around the waist, secrete hormones and other substances that fire inflammation. Although inflammation is an essential component of the immune system and part of the healing process, inappropriate inflammation causes a variety of health problems. Inflammation can make the body less responsive to insulin and change the way the body metabolizes fats and carbohydrates, leading to higher blood sugar levels and, eventually, to diabetes and its many complications. Another Obesity and Coronary Artery Disease. Numerous studies have demonstrated a direct association between excess body weight and coronary artery disease (CAD). The BMI-CAD Collaboration Investigators conducted a meta-analysis of 21 long-term studies that followed more than 300,000 participants for an average of 16 years. Study participants who were overweight had a 32 percent higher risk of developing CAD, compared with participants who were at a normal weight; those who were obese had an 81 percent higher risk. (9) Although adjustment for blood pressure and cholesterol levels slightly lowered the risk estimates, they remained highly significant for obesity. The investigators

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 is defined as the excessive build-up of body fat that has major detrimental effects on an individual’s health (Caballero, 2007). The major cause of this excess accumulation of body fat is due to a positive energy balance i.e. when the input of energy into the body system exceeds the output of energy which in turn facilitates in weight gain (Caballero, 2007). Obesity is a major health issue in modern day society, firstly because it affects approximately 300 million people worldwide (Weight Management Centre and secondly, drastic alteration in the body’s fat intake also leads to the increasing prevalence of other major health conditions such as cardiovascular disease, stroke, non-insulin dependent diabetes and hypertension (WMC, 2010).

Over two-thirds of adults in the United States are considered overweight or obese [1]. Obesity is a significant risk factor for a number of chronic conditions, including cardiovascular disease (CVD), type 2 diabetes, and metabolic syndrome [2], [3], [4]. Metabolic syndrome is a chronic disease characterized by the presence of individual risk factors including: insulin resistance, dyslipidemia (high plasma triglycerides, low high-density lipoprotein (HDL)), hyperglycemia, and hypertension [3, 5, 6]. When evaluating the individual components of metabolic syndrome, dyslipidemia, hypertension, and insulin resistance are also considered risk factors for CVD [3]. High fat mass (FM), especially in the form of visceral fat (VF), is commonly

Obesity is increasing throughout the world and is a combination of poor food choices and physical inactivity. It is the second leading cause of preventable deaths in the United States and is responsible for nearly 300,000 deaths per year. An obese human body consists of it carrying an excess amount of adipose tissue. Adipose tissue is an endocrine organ that secretes many products such as metabolites, cytokines, lipids, and coagulation factors. The human body needs some body fat for insulation, storing energy, and shock absorption, however obesity causes increased levels of circulating fatty acids and inflammation. Being obese can cause numerous problematic disease such as diabetes, heart disease, and high blood pressure. According to a research article by Eric Ravussin, PhD., “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 has steadily increased since 1960, a trend that has slowed in recent years but shows no sign of reversing. Today, 69 percent of U.S. adults are categorized as being affected by obesity or having excess weight.” (Obesity Society) Obesity continues to significantly impact our health-care costs in the United States. The cost of health-care for obese adults is close to two-hundred billion dollars a year.

Prevention of Obesity, which is among the high risk factors for cardiovascular disease women, will save lives of women. Obesity involves the consumption of high saturated fatty food and cholesterol, these fats are then deposited in the blood stream as majority cannot be emulsified by the liver and it deposits in the blood and some are deposited in the abdominal and other parts of the body. Cholesterol helps build new cells, insulate nerves and produce hormones. When there is too much cholesterol in the blood it builds up in the wall of the

Obesity is a serious medical condition that requires treatment to lower the risk of metabolic and cardiovascular disorders. However, one in three people in the United States is clinically obese (Overweight and Obesity Statistics) and 10-25% of obese individuals are labeled metabolically healthy (Bluher). Obesity is clinically diagnosed with a body mass index (BMI) of a score of 30 or greater in reference to the total weight in people’s body compared to their height (Overweight and Obesity Statistics). Although obesity is shown to increase mortality rate with associated metabolic and cardiovascular disorders, a recently classified observable trait of an individual, or phenotype, developed to separate the metabolically healthy from the unhealthy: Metabolically Healthy Obesity or MHO (Bluher). Whereas metabolism is the biological functions that maintain the living state of cells, metabolic health in reference to MHO is classified as being clinically obese while maintaining a waist size of a maximum 40 or 35 inches for a man and woman respectively, normal blood pressure, cholesterol and blood sugar compared to healthy individuals of their age groups, normal sensitivity to insulin and moderate physical fitness (Skerrett).

Cardiovascular diseases are the number one factor that can erupt from obesity due to the main causes that it brings, like high blood pressure, and LDL cholesterol to a high count while lowering HDL. LDL is the “bad cholesterol”, and HDL is the “good cholesterol”. We need fats in our body for energy or ATP, in our body. If we get more LDL, it can really be a dangerous case, and

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.
