WHAT IS OBESITY?
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health, leading to reduced life expectancy and/or increased health problems. In Western countries, people are considered obese when their body mass index (BMI), a measurement obtained by dividing a person’s weight by the square of the person’s height, is over 30 kg/m2, with the range 25–30 kg/m2 defined as overweight.
Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications, or psychiatric illness. 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.
Dieting and exercising are the main treatments for obesity. Diet quality can be improved by reducing the consumption of energy-dense foods, such as those high in fat and sugars, and by increasing the intake of dietary fiber. With a suitable diet, anti-obesity drugs may be taken to reduce appetite or decrease fat absorption. If diet, exercise, and medication are not effective, surgery may be performed to reduce stomach volume and/or bowel length, leading to feeling full earlier and a reduced ability to absorb nutrients from food.
Obesity is a leading preventable cause of death worldwide, with increasing rates in adults and children. Authorities view it as one of the most serious public health problems of the 21st century. Obesity is stigmatized in much of the modern world, though it was widely seen as a symbol of wealth and fertility at other times in history and still is in some parts of the world. In 2013, the American Medical Association classified obesity as a disease.
Whether you decide to have weight loss surgery or not, understanding your condition is vital for losing weight and keeping the weight off. Here are the most common causes of obesity:
• Genetics – Obesity can often be traced to genes, and the brain can induce appetite tendencies.
• Illness – Hypothyroidism, Cushing Syndrome and depression.
• Psychology – Mental illness and emotional problems.
• Lifestyle habits – Poor diet and low levels of daily activity.
You may be able to lose weight and improve your health by addressing the causes of your obesity.
But sometimes these attempts do not work without surgery. If you have been losing the battle with obesity, it may be time to consider bariatric surgery. To help you make a decision, talk to a qualified bariatric physician and surgeon.
