Obesity represents a great effort on the human body, and leads to short life. And obesity may
have been taken to many complications, such as: fatigue, heart problems ,
shortness of breath and exposure to atherosclerosis, high blood pressure,
diabetes and back pain, joints and ligaments, in addition to the large number
of infectious diseases and the inability to play sports or even walk which is
one of the simplest kinds of sports.
The causes of obesity
Of the main causes of obesity, eating too much, where
the weight is increased or decreased as a result of an increase or lack of
eating what the body needs calories, and can be defined as caloric as the
amount of energy generated by a certain amount of food, the more the person
obtained a larger amount of calories than needed these excess calories turn
into fat, and stored in the form of lipids in the body. But if the person
eating the amount of food contains fewer calories than your body needs, the
body converts part of the fat into energy.
pregnant women and children require an excessive
amount of calories for the growth process. But the increase in eating alone for
more than required without doubt increase fat in the body. The amount of food play
a major role in weight gain compared to the quality of the food. normal people
or obese people may have equal amounts of food, but the resulting difference in
weight is due to differences in the relationship between food intake and the
amount of energy used in each case.
There are centers in the brain responsible for
appetite and hunger and satiety. These centers make you stop food when you find
you are enough of it. And these centers make a person eats a sufficient
quantity to supply the body with enough of his need. While feeding centers that
make a person wants to eat , the satiety centers working to curb or stop
feeding centers , which makes a person willing to stop eating . The mechanism
of action of feeding and satiety centers is very complex.
There are several reasons help to stagger the work of
these centers, such as stress and genetic characteristics. Examples when person
become very disappointed this may lead to stop all physical activity. In such
case, the amount a person eats is bigger than he used to, which contributes to
weight gain, whereas other people are getting the movement to have in case of
disappointment, which helps in weight loss.
Some scientists say that giving infants a large amount
of eating up what they need increases the number of fat cells they have, and
these cells have the ability to store fat easily, making these children
susceptible to obesity throughout their lives.
The second reason
The second reason of the causes of obesity is the body
idle, when the human body is idle, it contributes to weight gain in all ages,
and it shows, especially in children and adolescents. Deals with obese
adolescents amount not to exceed what people eat natural, it has to eat less
than others, but in fact idle and thus eating Food when they devour outweigh
the amount of physical movement and turns it into fat which increases in weight.
The third reason
Genetics, scientists were able to identify a lot of
the relationship between genetics and obesity in animals, especially rats. This
relationship is based on genes; genes represent a unit cell that determines
genetic characteristics. Scientists have discovered that some of the mice have
genes causing the mechanism to stop the of satiety centers in the brain, while
these genes lead to make the bodies of these mice secrete a large amount of
chemicals called hormones.
But in humans, the role of genes is not known just as
is the case in animals, but researchers have found that there are signs that
some people are willing to obesity not others because of genetics. In a study
conducted on students in secondary schools found that only 8% of students
belonging to the parents of obese people have the thinnest.
And between families where one parent is obese, found
that 70% of children are obese. And between families, which includes father and
mother are obese, the percentage of 80% of children are obese. This study also
showed that the child within the family fledgling adoption does not appear
these cases genetic.
The fourth reason: Disease
The other reasons were initially occur as a result of the presence of
certain diseases, hitting some thyroid glands may make this gland secretes a
large amount of hormones into the blood circulation and these hormones in turn
affect the of satiety and feeding centers in the brain. In addition to the
above, the obesity may occur as a result of the brain injury centers on
nutrition and satiety, and it is by injury in accidents or infected by diseases
or cancerous tumor.
The effect of chemical drugs and herbal on obesity
The chemical and herbal medicine Affect to lose
weight, but there are negative effects for Pharmaceuticals has used chemical
property "Dinitrophenol" to lose weight, but there are side effects

(Amphetamines) but it turns out that this type of drug has psychological side
effects, one of these influences the appearance of the symptoms of addiction

seventies and use this property with another property is Phenteramine known as
(Ionamin, Fastin, Adipex - P) and is popularly known as Fen - Phen It is

The increased use of drug "Redux" and drug "Fen
– Phen" in 1997 where the use of more than two million dollars property
first, while used second drug about six million people in the late 1997
withdrew these drugs from the shelves of pharmacies after the Organization Food
Drug Administration the U.S. tested the hearts of 291 using the who turned out
to ruin their hearts valves have earned this ruin after the use of these
medications.
While herbal medicine used for weight loss has proven
its effectiveness and lack of side effects and herbal medicine used for weight
loss include:
