Pathophysiology Of Obesity Essay

Secondly, I began eating more nutritionally. I selected foods from the USDA Food Pyramid groups. I made sure that vegetables and fruits were a part of my daily diet. I limited sweets and salty crunchy snacks.

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.

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

Reducing the problem of obesity; there must be an organized educational, political and legislation movement that is supported at the community level. Information from evidence-based practices used by nurses, health care providers, and other collaborators like dieticians, physical therapists, and social workers help the client to achieve a more favorable outcome. These interventions focus on diet, exercise, and behavior modification should be encouraged by nurses. Giving the client the power to identify the factors that contribute to excess food intake, can help the client to eliminate or reduce causes. Establishing realistic weight loss goals and exercise / activity objectives like losing bodyweight 1-2 lb./week increase the likelihood of success, assessing the client’s knowledge and discuss well-balanced diet plans plays major role teaching about diet plans. Discussing behavior modification strategies, such as self-monitoring and environmental management can provide client is the reinforcement that is needed. (Pearson, 2015) Continuing assessment is necessary not only to evaluate the safety or weight loss strategies but also reinforce positive benefits of weight loss. Including families and other stakeholders, such as schools, parks, private partners and politicians at all levels, we can make the obesity issue a focus for change. (John, F., & Kirsten, P., 2014). For programs like this to be successful, outcomes should not

Obesity: one of the nation’s most critical health problems. “Overweight is defined as having excess body weight for a particular height from fat, muscle, bone, water, or a combination of these factors. Obesity is defined as having excess body fat” (“Centers for Disease Control and Prevention”). When energy input and output get out of balance, obesity arises. Many factors can cause someone to become obese such as genetics, metabolism, level of physical activity, and more. “Overweight and obesity are the result of “caloric imbalance”—too few calories expended for the amount of calories consumed—and are affected by various genetic, behavioral, and environmental factors” (“CDC Features - Obesity & Genetics”). “When a person eats and drinks more calories than he or she burns, the energy balance tips toward weight gain, overweight, and obesity” (“Understanding Adult Overweight and Obesity”). Obesity is increasing throughout the United States due to lack of healthy behaviors, big health risk, genetics and increasing in children and adults.

Weight management can be assisted through improvement in food and medical stuff, physical activity or behavioral change, with a combination of all three being most effective. Where possible, increased physical activity should be adopted, with 150-300 minutes of moderate activity, or 75-150 minutes of vigorous activity each week, which has been associated with improved health outcomes, irrespective of weight loss. The level of physical activity recommended will be dependent on an individual’s BMI, fitness levels, commodities and age.(Prof.hankey (2006))

APN can help patients engage in their care, thereby helping them understand their obesity and the practical measures to take for prevention and management. APN are one of the main resources for patients trying to understand and implement healthy behaviors. Because APN interact with the community along all levels of the healthcare continuum, we can significantly influence patients trying to lose weight and maintain weight loss (Miller, et al, 2008). One of the primary responsibilities is to provide both formal and informal patient education. . Moreover, as Nurse Practitioners, we need to be measuring the body mass index, achieving and maintaining a healthy weight, and encourage the parents to engage their children in regular physical activity. Also, educating and giving the parents the list of food groups those children at risk need to be consuming. Developing successful interventions for overweight and obesity, such as checking BMI, adivising parents to weigh their children, as well as motivating people to eat healthy meal such fat free diets. (Miller, et al, 2008). Therefore, APN who clearly articulates both a rationale for healthy behaviors and a practical approach to implementing them is more likely to have greater success as patient educators. Role modeling, healthy diet and lifestyle may positively impact the

Increasing physical activity and controlling total calorie intake to manage increased body weight are key factors in balancing calories to manage weight. Reducing the intake of calories from solid fats and added sugars, consume moderate levels of alcohol, and consume less than 300 mg per day of dietary cholestrol all play a major role in foods and food components to reduce. Choosing a variety of protein foods and increase vegetable and fruit intake are foods and nutrients to increase

A person becomes obese when the balance between calories in and calories out becomes unbalanced. When you take more calories in than your body is using, you gain weight and when you continue to gain weight you become overweight and it will ultimately lead to obesity. Obesity in adults is typically defined using body mass index (BMI), a measure of weight to height (Wolin, 2009). The Center for Disease Control (CDC) states that an adult BMI between 25 and 29.9 is considered overweight and an adult who has a BMI of 30 or higher is considered obese. Calculating the BMI is not the only way to calculate obesity.

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

At the outset of treatment, the patient and health care provider should discuss and agree upon goals. The goals must take into account the food habits, exercise behaviors, psychological outlook and support systems of the individual. Realistic expectations, short- and long-term, may be promoted by a discussion of a healthy weight versus an ideal body weight. Features of weight management
