Metabolic syndrome is a clustering of at least three of the following five medical conditions: abdominal obesity, high blood pressure, high blood sugar, high serum triglycerides, and low serum high-density lipoprotein (HDL).
Abdominal obesity, also known as central obesity and truncal obesity, is the human condition of an excessive concentration of visceral fat around the stomach and abdomen to such an extent that it is likely to harm its bearer's health. Abdominal obesity has been strongly linked to cardiovascular disease, Alzheimer's disease, and other metabolic and vascular diseases.
Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
Fatty liver disease (FLD), also known as hepatic steatosis and steatotic liver disease (SLD), is a condition where excess fat builds up in the liver. Often there are no or few symptoms. Occasionally there may be tiredness or pain in the upper right side of the abdomen. Complications may include cirrhosis, liver cancer, and esophageal varices.
Diseases of affluence, previously called diseases of rich people, is a term sometimes given to selected diseases and other health conditions which are commonly thought to be a result of increasing wealth in a society. Also referred to as the "Western disease" paradigm, these diseases are in contrast to so-called "diseases of poverty", which largely result from and contribute to human impoverishment. These diseases of affluence have vastly increased in prevalence since the end of World War II.
Bariatrics is the branch of medicine that deals with the causes, prevention, and treatment of obesity.
Metabolic dysfunction–associated steatotic liver disease (MASLD) is the name adopted in 2023 for the condition previously known as non-alcoholic fatty liver disease (NAFLD). This condition is diagnosed when there is excessive fat build-up in the liver, and at least one metabolic risk factor. When there is also moderate alcohol use, the term MetALD is used, and these are differentiated from alcoholic liver disease (ALD) when this is the sole cause of steatotic liver disease. The terms non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis have been used to describe different severities, the latter indicating the presence of further liver inflammation. NAFL is less dangerous than NASH and usually does not progress to it, but this progression may eventually lead to complications, such as cirrhosis, liver cancer, liver failure, and cardiovascular disease.
Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.
Being overweight is having more body fat than is optimally healthy. Being overweight is especially common where food supplies are plentiful and lifestyles are sedentary.
Obesity has been observed throughout human history. Many early depictions of the human form in art and sculpture appear obese. However, it was not until the 20th century that obesity became common — so much so that, in 1997, the World Health Organization (WHO) formally recognized obesity as a global epidemic and estimated that the worldwide prevalence of obesity has nearly tripled since 1975. Obesity is defined as having a body mass index (BMI) greater than or equal to 30 kg/m2, and in June 2013 the American Medical Association classified it as a disease.
Maternal obesity refers to obesity of a woman during pregnancy. Parental obesity refers to obesity of either parent during pregnancy.
Diet plays an important role in the genesis of obesity. Personal choices, food advertising, social customs and cultural influences, as well as food availability and pricing all play a role in determining what and how much an individual eats.
Pacific island nations and associated states make up the top seven on a 2007 list of heaviest countries, and eight of the top ten. In all these cases, more than 70% of citizens aged 15 and over are obese. A mitigating argument is that the BMI measures used to appraise obesity in Caucasian bodies may need to be adjusted for appraising obesity in Polynesian bodies, which typically have larger bone and muscle mass than Caucasian bodies; however, this would not account for the drastically higher rates of cardiovascular disease and type 2 diabetes among these same islanders.
Weight management refers to behaviors, techniques, and physiological processes that contribute to a person's ability to attain and maintain a healthy weight. Most weight management techniques encompass long-term lifestyle strategies that promote healthy eating and daily physical activity. Moreover, weight management involves developing meaningful ways to track weight over time and to identify the ideal body weights for different individuals.
Obesity in the Middle East and North Africa is a notable health issue. Out of the fifteen fattest nations in the world as of 2014, 5 were located in the Middle East and North Africa region.
Management of obesity can include lifestyle changes, medications, or surgery. Although many studies have sought effective interventions, there is currently no evidence-based, well-defined, and efficient intervention to prevent obesity.
A number of lifestyle factors are known to be important to the development of type 2 diabetes including: obesity, physical activity, diet, stress, and urbanization. Excess body fat underlies 64% of cases of diabetes in men and 77% of cases in women. A number of dietary factors such as sugar sweetened drinks and the type of fat in the diet appear to play a role.
This article provides a global overview of the current trends and distribution of metabolic syndrome. Metabolic syndrome refers to a cluster of related risk factors for cardiovascular disease that includes abdominal obesity, diabetes, hypertension, and elevated cholesterol.
Obesity is defined as an abnormal accumulation of body fat, usually 20% or more over an individual's ideal body weight. This is often described as a body mass index (BMI) over 30. However, BMI does not account for whether the excess weight is fat or muscle, and is not a measure of body composition. For most people, however, BMI is an indication used worldwide to estimate nutritional status. Obesity is usually the result of consuming more calories than the body needs and not expending that energy by doing exercise. There are genetic causes and hormonal disorders that cause people to gain significant amounts of weight but this is rare. People in the obese category are much more likely to suffer from fertility problems than people of normal healthy weight.
Obesity in Thailand has been flagged as a major source of health concern, with 32% of the population identifying as overweight and 9% obese. With reference to 2016 data from the World Health Organization (WHO), Thailand has one of the highest incidence of overweight citizens in the South East Asian region, second to only Malaysia. The Thai National Health Examination Surveys (NHES) found that obesity in Thailand more than doubled during the period 1991-2014. This spike in obesity levels has been largely attributed to increased access to junk food, and unhealthy switches from active to sedentary lifestyles. These factors are closely linked to economic growth in the country.
