Facts about Obesity

The facts Obesity is the leading cause of preventable disease and death in North America. In recent years, the number of overweight people in industrialized countries has increased so dramatically that the World Health Organization has described obesity as an epidemic. In the United States, 69% of the adult population is overweight or obesity.


In Canada, self-reported data show that 40% of men, 27% of women are overweight, 20% of men and 17% of women are obese. People with obesity are at higher risk for serious medical conditions such as high blood pressure, heart attacks, stroke, diabetes, gallbladder disease, and cancers that are different from those with a healthy weight. the reasons Obesity occurs when your body consumes more calories than it burns. In the past, many people thought that obesity was simply caused by over-eating and lack of exercise, due to lack of will and self-control. Although these factors contribute significantly, doctors are aware that obesity is a complex medical problem involving genetic, environmental, behavioral and social factors. All these factors play a role in determining a person's weight. Recent research shows that in some cases, certain genetic factors may cause changes in the appetite and metabolism of fats that lead to obesity. 

For a person at risk of gaining weight (for example, has less metabolism) and leading an inactive and unhealthy lifestyle, the risk of obesity is high. Although a person's genetic makeup may contribute to obesity, it is not the main cause. Environmental and behavioral factors have a greater impact - consuming excess calories from high-fat foods and doing little or no daily physical activity over the long term will lead to weight gain. Psychological factors may also promote obesity. Low self-esteem, guilt, stress or trauma can lead to over-eating as a way to deal with the problem. Some medical conditions such as binge eating disorder (BED), Cushing's disease and polycystic ovary syndrome can lead to overweight and obesity. BED is an eating disorder where a person suffers from frequent bouts of over-eating. During these episodes, the individual eats a large amount of food quickly and feels no control over the food. Symptoms and complications Health risks associated with obesity include: Respiratory disorders (eg, sleep apnea, chronic obstructive pulmonary disease) Certain types of cancers (such as prostate cancer, intestines in men, breast cancer and uterine cancer in women) Coronary artery disease (heart) depression diabetic Gallbladder disease or liver disease Gastroesophageal reflux disease (GERD) high blood pressure High fat Arthritis (for example, osteoporosis) brain attack People with obesity may suffer from symptoms of medical conditions mentioned above. High blood pressure, high cholesterol levels, breathing problems, and joint pain (in the knees or lower back) are common. 

The more people who are obese, the more likely they are to have medical problems related to obesity. Apart from medical complications, obesity is also associated with psychosocial problems such as low self-esteem, discrimination, difficulty in finding employment and low quality of life. Make the diagnosis Obesity diagnosis is usually based on physical examination and patient history (ie eating habits and exercise). A measurement called body mass index (BMI) does not directly measure body fat, but is a useful tool for assessing health risks associated with weight gain or obesity. BMI is 18.5 to 24.9 within the health range. BMI is calculated using kilograms (kg) and meters (m) instead of pounds (pounds) and inches / feet. Keep in mind that 1 lb is 0.45 kg and 1 inch equals 0.0254 m. BMI is calculated as follows: Body mass index = body weight (kg) he height² (m) Example: If you weigh 150 pounds (68 kg) and 5'8 "(1.73 m), section 68 b (1.73 × 1.73), or 2.99. 

The result is 22.74, which lies in the middle of a healthy range. The Canadian Health Department classifies body mass index according to the risks associated with the development of health problems: Body Mass Index Classification * Health Risks Less than 18.5 overweight 18.5 to 24.9 natural weight less 25.0 to 29.9 overweight 30.0 to 34.9 of the high fat I 35.0 to 39.9 of the class II obesity is very high 40 or higher of the fat layer 3 is extremely high * The above classification does not apply to persons under the age of 18, pregnant women, or breastfeeding women. For people 65 years of age and older, the "natural" range is higher and starts slightly above 18.5 and extends to the "overweight" range. Doctors may also use other measurements, such as waist size, to assess the health risks associated with excess abdominal fat. When BMI and waist size indicate a high risk of health problems, additional tests can also be performed. Canadian Body Weight Rating guidelines are available online.
