Obesity has a different meaning for everyone. In most women and men, obesity means being overweight far exceeds the desired weight.
Sometimes we are often confused with the understanding of obesity and overweight, even though these two words have different senses. Obesity is a condition where there is an excess accumulation of body fat, so that a person's weight well above normal and can be harmful to health. While overweight is a state where a person's weight exceeds the normal weight.
Many people have different opinions on obesity, but here are some definitions of obesity based on medical science:
- A condition in which body fat is in an excessive amount
- A chronic disease that can be treated
- An epidemic disease
- A condition associated with other diseases and can reduce the quality of life
Treatment of obesity requires a very high maintenance costs, so many people prefer a natural treatment to treat obesity.
Obesity occurs because of imbalance between energy intake with energy out. Body Mass Index (BMI) has been recognized as the most practical method of determining the level of overweight and obesity in adults under the age of 70.
Many researchers claim that obesity is a "time bomb" that must be wary of. Unsightly addition, obesity also save a lot of the negative side. Body so tired, troubled breathing, and even stop breathing during sleep. And more frightening, too fat makes the body prone to infestation of diseases such as diabetes, high blood pressure, high cholesterol, heart disease, and arthritis. Obesity is not only associated with physical illness, but also with psychiatric problems, particularly anxiety.
Causes of obesity
Genetic
Obesity can be decreased in the family but the mechanism is still remains unclear, although family members are genetically predisposed to having excess weight. This is possible because many genes are involved in the process of energy expenditure and income. Research conducted in 1994 against the obese gene in mice has opened up insights into this field. Obese gene is a protein known as leptin and produced by fat cells (adiposity) that are secreted into the blood. Leptin serves as an ambassador (massanger) from adipose tissue that provides information to the brain about the size of fat mass. One of the main effects as inhibitors of the synthesis and release of neuropeptide Y, by increasing food intake, lowering thermogenesis and increase insulin levels. Leptin tells the brain about the amount of fat available, but in obese people this process may not function properly.
Factors Physiology
Overweight and Obesity increases with increasing age and then declines before finally stopping in the elderly. BMI also increased in women who are pregnant.
Socio-Economic Factors
In everyday life there is a contradiction in the relationship between social economic status and prevalence of overweight. Low social level, where food is difficult to obtain, overweight appears as a visual indicator of the level of prosperity and status. But on the contrary, at a higher social level, emaciation is considered as a desire that must be achieved while overweight is seen as an indicator of lower status.
Behavior and Psychology
For individuals who are inactive, including those who rarely exercise, consume alcohol and smoking - tends to increase BB. Although alcohol may have the effect of 'cardioprotective', but excessive consumption can lead to excess energy intake, resulting in liver and gastrointestinal diseases, such as gallblader disease.
Smokers tend to have a lighter weight than the former smokers, and those who never smoked is between the two groups. Psychological factors also influence eating habits. Eating, for some people it can also provide a negative response from the emotions, such as boredom and sadness.
