Obesity is a medical condition A disease or medical condition is an abnormal condition of an organism that impairs bodily functions, associated with specific symptoms and signs. It may be caused by external factors, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases in which excess body fat In histology, adipose tissue or body fat or just fat is loose connective tissue composed of adipocytes. It is technically composed of roughly only 80% fat; fat in its solitary state exists in the liver and muscles. Adipose tissue is derived from lipoblasts. Its main role is to store energy in the form of fat, although it also cushions and has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy Life expectancy is the expected number of years of life remaining at a given age. It is denoted by ex, which means the average number of subsequent years of life for someone now aged x, according to a particular mortality experience. (In technical literature, this symbol means the average number of complete years of life remaining, ie excluding and/or increased health problems.[1][2] Body mass index The body mass index , or Quetelet index, is a statistical measure which compares a person's weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight based on a person's height. Due to its ease of measurement and calculation, it is the most widely used diagnostic tool to (BMI), a measurement which compares weight Although some people prefer the less-ambiguous term body mass, the term body weight is overwhelmingly used in daily English speech as well as in the contexts of biological and medical sciences to describe the mass of an organism's body. Body weight is measured in kilograms throughout the world, although in some countries people more often measure and height, defines people as overweight (pre-obese) Overweight is generally defined as having more body fat than is optimally healthy. Being overweight is a common condition, especially where food supplies are plentiful and lifestyles are sedentary. As much as 64% of the United States adult population is considered either overweight or obese, and this percentage has increased over the last four when their BMI is between 25 kg/m2 and 30 kg/m2, and obese when it is greater than 30 kg/m2.[3]
Obesity increases the likelihood of various diseases Whether obesity should be considered a disease on its own, it is also an important risk factor for many chronic physical and mental illnesses, particularly heart disease Cardiovascular disease or cardiovascular diseases is the class of diseases that involve the heart or blood vessels . While the term technically refers to any disease that affects the cardiovascular system (as used in MeSH), it is usually used to refer to those related to atherosclerosis (arterial disease). These conditions have similar causes,, type 2 diabetes Diabetes mellitus type 2 or type 2 diabetes (formerly called non-insulin-dependent diabetes mellitus , or adult-onset diabetes) is a disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. While it is often initially managed by increasing exercise and dietary modification,, breathing difficulties during sleep Obstructive sleep apnea is a common sleep apnea caused by obstruction of the airway. It is characterized by pauses in breathing during sleep. These episodes, called apneas (literally, "without breath"), each last long enough that one or more breaths are missed, and occur repeatedly throughout sleep. In obstructive sleep apnea, breathing, certain types of cancer Cancer /ˈkænsə/ ( listen) (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant, and osteoarthritis Osteoarthritis , is a group of diseases and mechanical abnormalities involving degradation of joints, including articular cartilage and the subchondral bone next to it. Clinical manifestations of OA may include joint pain, tenderness, stiffness, creaking, locking of joints, and sometimes local inflammation. In OA, a variety of potential forces—.[2] Obesity is most commonly caused by a combination of excessive dietary calories Food energy is the amount of energy available from food that is available through respiration, lack of physical activity, and genetic susceptibility Inheritance of quantitative traits or polygenic inheritance refers to the inheritance of a phenotypic characteristic that varies in degree and can be attributed to the interactions between two or more genes and their environment. Though not necessarily genes themselves, quantitative trait loci are stretches of DNA that are closely linked to the, although a few cases are caused primarily by genes A gene is the basic unit of heredity in a living organism. All living things depend on genes. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring. A modern working definition of a gene is "a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated, endocrine The endocrine system is a system of glands, each of which secretes a type of hormone to regulate the body. The endocrine system is an information signal system much like the nervous system. Hormones regulate many functions of an organism, including mood, growth and development, tissue function, and metabolism. The field of study that deals with disorders, medications A pharmaceutical drug, also referred to as medicine, medication or medicament, can be loosely defined as any chemical substance intended for use in the medical diagnosis, cure, treatment, or prevention of disease or psychiatric illness A mental disorder or mental illness is a psychological or behavioural pattern that occurs in an individual and is thought to cause distress or disability that is not expected as part of normal development or culture. The recognition and understanding of mental health conditions has changed over time and across cultures, and there are still. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited; on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass.[4][5]
The primary treatment for obesity is dieting Dieting is the practice of ingesting food in a regulated fashion to achieve or maintain a controlled weight. In most cases dieting is used in combination with physical exercise to lose weight in those who are overweight or obese. Some athletes however aspire to gain weight . Diets can also be used to maintain a stable body weight and physical exercise Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health. It is performed for many different reasons. These include strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance and for enjoyment. Frequent and regular physical exercise boosts the immune system,. To supplement this, or in case of failure, anti-obesity drugs Anti-obesity medication or weight loss drugs refer to all pharmacological agents that reduce or control weight. These drugs alter one of the fundamental processes of the human body, weight regulation, by either altering appetite, metabolism, or absorption of calories. It is common for them to be tried and if there is little or no benefit from them may be taken to reduce appetite or inhibit fat absorption. In severe cases, surgery Bariatric surgery, or weight loss surgery, is a type of procedure performed on people who are dangerously obese, for the purpose of losing weight. This weight loss is usually achieved by reducing the size of the stomach with an implanted medical device or through removal of a portion of the stomach (sleeve gastrectomy or biliopancreatic diversion is performed or an intragastric balloon is placed to reduce stomach volume and/or bowel length, leading to earlier satiation and reduced ability to absorb nutrients from food.[6][7]
Obesity is a leading preventable cause of death The World Health Organization traditionally classified death by either disease or injury. It however may also be classified in terms of preventable risk factors which then lead to the traditional classification of disease states worldwide, with increasing prevalence In epidemiology, the prevalence of a disease in a statistical population is defined as the total number of cases of the disease in the population at a given time, or the total number of cases in the population, divided by the number of individuals in the population. It is used as an estimate of how common a condition is within a population over a in adults and children Childhood obesity is a condition where excess body fat negatively affects a child's health or wellbeing. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health, and authorities view it as one of the most serious public health Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to the overall health of a community based on population health analysis. The problems of the 21st century.[8] Obesity is stigmatized Social stigma is severe social disapproval of personal characteristics or beliefs that are perceived to be against cultural norms in the modern Western world The Western world, also known as the West and the Occident , is a term that can have multiple meanings depending on its context (e.g., the time period, the region or social situation). Accordingly, the basic definition of what constitutes "the West" varies, expanding and contracting over time, in relation to various historical, though it has been perceived as a symbol of wealth and fertility at other times in history, and still is in many parts of Africa.[2][9]
