Obesity means different things to different people. To most men and women, it means to be greatly overweight or to be larger than they wish to be. The term “obesity” is often used interchangeably with “overweight”, but the two are not identical. Obesity may be defined as the excess accumulation of body fat sufficient to endanger health. Overweight means only that a person carries more weight than normal for their height. Researchers and physicians define obesity as:
An excess of body fat.
A multifactorial chronic disease that requires medical treatment
A consequence of excess intake of dietary fat
An epidemic disease
A condition associated with other diseases and decreased quality of life
A major contributor to the costs of Health Care Obesity results when there is an imbalance between energy intake and energy expenditure. In simple terms, you consume more calories than you expend in normal daily activities. The Body Mass Index, ( most commonly referred to as BMI ) is accepted as the most useful measure of body fat (obesity ), in adults below the age of 70 years.
A BMI measures peoples weight in relation to their height, and can be used to determine how much risk a person has of developing certain health problems because of his or her weight. An individual is defined medically obese, if they have a BMI of above 30, which results in 20% excess body weight. why do people get fat?
There is no one reason why people suffer from obesity. Obesity is caused by a mixture of factors including diet, lifestyle, genetics, gender and behavioral patterns. Fatty fast foods, labor-saving devices and our sedentary working habits could be making us FAT. Experts agree that our affluent society and the stress and tension associated with modern living, all have an impact on our excessive accumulation of body fat.
Obesity is a major risk factor for many chronic diseases, including types of diabetes,, coronary heart disease, gallstones and certain cancers. In addition, it exacerbates other conditions such as hypertension,dyslipidaemia and arthritis. The medical benefits of weight reduction and the long-term prevention of regain are self evident. It is now clear that even a modest weight loss of 5-10% can produce significant health benefits. Until now, the options available for the clinician for the treatment of obesity, have been limited. Behavioral approaches, encouraging patients to reduce calories and increase exercise are usually met with poor compliance. Where weight is lost, it is, in most cases, regained.a new era.
XENICAL is the first in a new class of drugs for the treatment of obesity. XENICAL is a potent, specific and long-acting inhibitor of gastric and pancreatic lipases, preventing the hydrolysis and subsequent absorption of 30% of ingested dietary fat. It exerts its therapeutic activity in the lumen of the stomach and small intestine. Systemic absorption of the drug is, therefore, not required for activity. In clinical studies, compared to those on diet alone, patients taking XENICAL:
Lost significantly more weight – nearly twice as much
Maintained their weight loss better than those on diet alone
Reduced total cholesterol
Reduced LDL cholesterol
Improved LDL/HDL ratio
Improved elevated blood pressure
Improved insulin levels and glycemic control in patients with non-insulin-dependent diabetes mellitus (NIDDM)
Reduced risk factors for developing NIDDM
