Obesity is an epidemic in the United States. This condition puts people at a higher risk for serious diseases, such as type 2 diabetes, heart disease, and cancer.
According to the Centers for Disease Control and Prevention (CDC), it’s estimated that in 2015–2016, 93.3 million (39.8 percent) American adults and 13.7 million (18.5 percent) American children and teens are clinically obese.
Obesity is defined as having a body mass index (BMI) of 30 or more. BMI is a calculation that takes a person’s weight and height into account. However, BMI does have some limitations.
According to the CDC, “Factors such as age, sex, ethnicity, and muscle mass can influence the relationship between BMI and body fat. Also, BMI doesn’t distinguish between excess fat, muscle, or bone mass, nor does it provide any indication of the distribution of fat among individuals.”
Despite these limitations, BMI continues to be widely used as an indicator of excess weight.
What causes obesity?
Eating more calories than you burn in daily activity and exercise (on a long-term basis) causes obesity. Over time, these extra calories add up and cause you to gain weight.
Common specific causes of obesity include:
eating a poor diet of foods high in fats and calories
having a sedentary (inactive) lifestyle
not sleeping enough, which can lead to hormonal changes that make you feel hungrier and crave certain high-calorie foods
genetics, which can affect how your body processes food into energy and how fat is stored
growing older, which can lead to less muscle mass and a slower metabolic rate, making it easier to gain weight
pregnancy (weight gained during pregnancy can be difficult to lose and may eventually lead to obesity)
Certain medical conditions may also lead to weight gain. These include:
polycystic ovary syndrome (PCOS): a condition that causes an imbalance of female reproductive hormones
Prader-Willi syndrome: a rare condition that an individual is born with which causes excessive hunger
Cushing syndrome: a condition caused by having an excessive amount of the hormone cortisol in your system
hypothyroidism (underactive thyroid): a condition in which the thyroid gland doesn’t produce enough of certain important hormones
osteoarthritis (and other conditions that cause pain that may lead to inactivity)
Who is at risk for obesity?
A complex mix of genetic, environmental, and psychological factors can increase a person’s risk for obesity.
Some people possess genetic factors that make it difficult for them to lose weight.
Environment and community
Your environment at home, at school, and in your community, can all influence how and what you eat and how active you are. Maybe you haven’t learned to cook healthy meals or don’t think you can afford healthier foods. If your neighborhood is unsafe, maybe you haven’t found a good place to play, walk, or run.
Psychological and other factors
Depression can sometimes lead to weight gain, as people turn to food for emotional comfort. Certain antidepressants can also increase risk of weight gain.
It’s a good thing to quit smoking, but quitting can also lead to weight gain. For that reason, it’s important to focus on diet and exercise while you’re quitting.
Medications such as steroids or birth control pills can also put you at greater risk for weight gain.
How is obesity diagnosed?
Obesity is defined as having a BMI of 30 or more. Body mass index is a rough calculation of a person’s weight in relation to their height.
Other more accurate measures of body fat and body fat distribution include skinfold thickness, waist-to-hip comparisons, and screening tests such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) scans.
Your doctor may also order certain tests to help diagnose obesity as well as obesity-related health risks. These may include blood tests to examine cholesterol and glucose levels, liver function tests, diabetes screen, thyroid tests, and heart tests,
