How Does Bariatric Surgery Work?
Bariatric surgery, such as gastric bypass, gastric sleeve, and laparoscopic adjustable gastric banding, work by changing the anatomy of your gastrointestinal tract (stomach and digestive system) or by causing different physiologic changes in your body that change your energy balance and fat metabolism. Regardless of which bariatric surgery procedure you and your surgeon decide is best for you, it is important to remember that bariatric surgery is a “tool.” Weight loss success also depends on many other important factors, such as nutrition, exercise, behavior modification, and more.
By changing your gastrointestinal anatomy, certain bariatric procedures affect the production of intestinal hormones in a way that …show more content…
This unbalanced change in energy can often lead to weight regain.
Significant weight loss is also associated with a number of other changes in your body that help to reduce defects in fat metabolism. With increased weight loss, you will find yourself engaging in more physical activity. Individuals who find themselves on a weight-loss trend often engage in physical activity, such as walking, biking, swimming, and more. Additionally, increased physical activity combined with weight loss may often improve your body’s ability to burn fat, lead to a positive personal attitude, and decrease stress levels. Massive weight loss, as a result of bariatric surgery, also reduces hormones such as insulin (used to regulate sugar levels) and cortisol (stress hormone) and improves the production of a number of other factors that reduce the uptake and storage of fat into fat storage depots. Physical activity is also a very important component of combating …show more content…
Long Term Weight Loss Success
Bariatric surgeries result in long-term weight-loss success. Most studies demonstrate that more than 90 percent of individuals previously affected by severe obesity are successful in maintaining 50 percent or more of their excess weight loss following bariatric surgery. Among those affected by super severe obesity, more than 80 percent are able to maintain more than 50 percent excess body weight loss.
Improved Longevity
Several large population studies find that individuals affected by severe obesity who have had bariatric surgery have a lower risk of death than individuals affected by obesity who do not have surgery. One of these studies found up to an 89 percent greater reduction in mortality throughout a 5-year observation period for individuals who had bariatric surgery when compared to those who did not. Another large population study comparing mortality rates of bariatric and non-bariatric patients found a greater than 90 percent reduction in death associated with diabetes and a greater than 50 percent reduction in death from heart

Synthesis of Bariatric Surgery and the Effects on Comorbidities

...Synthesis of Bariatric Surgery and the Effects on Comorbidities  Abstract This synthesis of literature provides a summary of the data that has been collected over the years through experimentation, literature reviews, qualitative research, and the results that have been construed from that data will be presented. It discusses the concept of the effects of bariatric surgery and answers the question - do people who have the surgery have better health outcomes, specifically with hypertension and type II diabetes mellitus, than those who do not? A summary of research reveals that there is a significant reduction and/or total remission of both of these co-morbidities that were often life long. Other benefits, such as quality of life, social standings, and healthcare cost reduction are examined and positively reported. Review of current data to include strengths and weaknesses, conceptual frameworks, and the current state of knowledge reveal that bariatric procedures have shown the efficacy and safety in the treatment of morbid obesity and have gained wider acceptance in the medical world. Synthesis of Bariatric Surgery and the Effects on Comorbidities For years people have turned to diets in an effort to lose weight and get healthier.

Nursing

...METHODOLOGY The objective of this chapter is to define nursing research, analyse methods of research and outline methodological process used to find articles on which to base this extended literature review. In this hypothesis, the reason for literature review is to ascertain whether or not gastric banding is an effective treatment for obesity in young adults as measured by physical functioning. The research process is the step-by-step procedure of developing research paper (Boje, 2001). It normally consists of following stages: detection of the research problem; preparation of search plan; searching and assessing the literature; data collection and evaluation; formulating a research design; and presenting the research findings (Cormack, 1996). The ability of nurses and other health care professionals to locate and identify existing literature on a relevant topic is an essential nursing skill (Burns & Grove, 2003). The sources where they can gain and expand research knowledge from may include personal or specialist experiences and clinical procedures and guidelines (Eccles & Mason, 2001). Before they can be made assessable to health care workers, guidelines and procedures are required to go through rigorous process of dissemination, before they can be made assessable to health care workers to be used in practice (Craig & Smith, 2007). Some of the organisations responsible for underwriting and implementation of clinical guidelines into clinical practice...

According to the Mayo Clinic “Almost two-thirds of Americans are classified as overweight, obese, or extremely (morbidly) obese and these numbers are expected to increase.”(Curry, 2003) Obesity is basically the buildup of body fat, which usually is around 20% or more over the ideal body weight. The division of medicine that treats and manages of obesity is known as bariatrics. Obesity has become a key health problem in the United States, therefore Gastric Bypass surgery has become a significant therapeutic option because of its documented efficiency in causing significant weight loss with a consequent improvement in comorbid conditions such as coronary artery disease, hypertension and diabetes. Bariatric surgery is a very invasive medical procedure that can causes dramatic weight loss which is accomplished by decreasing the size of the stomach with a gastric band or by removing a portion of the stomach itself. Weight loss surgery is the most effective and sustainable treatment option for the morbidly obesity as long as the individual is motivated to make the lifestyle changes required (Madura, 2012). Currently, bariatric surgery is the one obtainable treatment for morbidly obese individuals that consistently...

...Gastric Bypass and Diabetes Literature Research Shayne Howard Grand Canyon University: NRS-433V Introduction to Nursing Research 03/19/2016 Introduction Diabetes is one of the most deadly diseases known to man. That is a bold statement but when you consider that a big percentage of the other most deadly diseases like heart disease, kidney failure and strokes can be caused by diabetes then it puts it in to perspective. Diabetes causes many health problems besides these as well. The complications associated with diabetes are numerous but include neuropathy, blindness, amputation, impotency, depression and cognitive decline just to name a few. Some of these complications are inevitable but they can be avoided or at least prevented for an amount of time with proper diet and exercise or following a medication regimen. For some however the disease hits too hard too fast or because of physical restraints exercise is not a viable option. For these patients a surgical option such as weight loss surgery may be their only recourse. There are 4 major types of weight loss surgery that can be used to treat morbid obesity and in turn diabetes. There are the Roux-En-Y Gastric Bypass, the Gastric sleeve, Gastric banding, and the Duodenal switch. The most popular for mild weight loss is the gastric band in which an adjustable band is place around the stomach limiting the size and thereby limiting the amount of food intake. This is less invasive and reversible but also less effective overall...

...income populations are more at risk for obesity and its co-morbidities. Some contributors to obesity are physical and social environments that promote foods high in fat and calories. Coincidently, promote environments with little or no physical activities. Even with these environments that contribute to bad nutrition and sedentary lifestyles, society still view obesity is as a personal responsibility. Nurses addressing the obesity epidemic require a shift from the norm of blaming individuals for the lack of will power to control their eating and physical activity but toward a healthy environment as a primary determinant. This paper addresses the obesity crisis from individual, family, local community and public policy perspectives and the nurses’ role to promote change, advocate for policy initiatives, and help reverse the obesity epidemic. This paper also addresses the nurse’s role in anticipating obesity related issues, such as, skin, pulmonary, intravenous access, and mobility. Challenges are considered and interventions to address these issues are presented. Nurses Addressing the Obesity Epidemic Obesity is a major concern for the healthcare professional because it has become an epidemic in the United States of America.

Quality measures such as performance measurement and quality improvement processes play a critical role in helping organizations achieve quality outcomes. This paper will contrast performance measurement and quality improvement processes. In addition, this paper will discuss a healthcare organization, Gulf Coast Medical Center, its mission and QI goals, and the role of the consumer and stakeholders in the QI process. Performance Measurement vs. Quality Improvement Processes Performance measures are an important element of the overall quality management of an organization. “Performance measures quantitatively tell us something important about our products, services, and the processes that produce them” (Oak Ridge Institute for Science and Education, n.d.). In the healthcare industry, performance measures are a tool used to help understand, manage, and improve what healthcare organizations do. Performance measures are composed of units of measure; a number to tell how much, a unit to give the number a meaning of what, each tying in to the overall target number. In contrast, quality improvement (QI) focuses on bridging the gap between current levels of quality and expected levels of quality. “QI uses...

Obesity

...Health Promotion: Adult Obesity NURP 570: Health Promotion: A Global Perspective February 10, 2016 Health Promotion: Adult Obesity Obesity has become America’s most serious epidemic. After smoking, it is the leading cause of preventable, premature death in the United States (Daddario, 2007). An estimated 400,000 deaths are attributed to obesity in the United States each year (Christou, 2004). Higher death rates are also attributed to secondary conditions and diseases related to obesity. Nurse practitioners are involved in many aspects of the overweight or obese patient’s care. This care can be managed directly in a weight management program (teaching and counseling for conventional weight management or bariatric surgery) or through providing care to the patient affected by one or more of the many comorbidities of obesity (Daddario, 2007). Lifestyle changes are relevant when a patient’s body mass index (BMI) has increased to 25–29.9 or the point of being overweight. Behavior change models are important to prevent weight gain and to help the person meet the goal of living a healthier, longer life. The Health Belief Model (HBM) addresses the effects of beliefs on health and the decision process of making behavioral changes (Daddario, 2007). The HBM consists of five components (Edelman, 2013). * Perceived susceptibility is a person’s perceived risk for contracting an illness or health condition of concern to the researchers. * Perceived severity is a person’s perception...

Personal Framework

...I have a little more than two years working experience as a nurse on the medical surgical floor that focuses on orthopedic and bariatric patients. I also have another job as a medication assistant at Austin Community College (ACC). This job allows me to collaborate with a nursing instructor by educating level one nursing students in a hospital setting in medication administration safety, basic nursing skills, critical thinking skills, evidence-based practice, core measures, and providing effective and holistic nursing care. My goals as a nurse is to build a trusting relationship with my patients and promote the patient’s sense of control in order to attain quality, holistic health. These goals are very similar with my ACC students. As I assist in teaching them how to reach their potential as a future nurse, I want us to trust each other, and I want them to be autonomous in researching answers themselves to provide quality care. My nursing care before this class was more focused on evidence-based practice since I did not consciously incorporate theory into my bedside practice. This personal framework paper will review my personal values, beliefs, and nursing philosophy in relation to my bedside nursing practice and medication assistant position. I will describe Erickson, Tomlin, and Swain’s Modeling and Role Modeling Theory (MRMT) and how it applies to the nursing metaparadigm and my nursing practice. I will further compare and contrast the theory of Modeling and Role Modeling...
