Obesity is the accumulation of fat in the body, resulting in the appearance of excess body weight. At the same time, fat deposits of the body (subcutaneous adipose tissue and around internal organs) accumulate more fat. The causes of obesity can be different.
Obesity is of two types: the upper (“male”) type, when fat accumulates mainly in the abdomen and above, and the lower (“female”) type when the hips and buttocks accumulate fat.
Slender beauty shines on the catwalks. Television shows obese people only in feature films and in advertising remedies for losing weight. And overweight people are discriminated against in everyday life.
Causes of obesity: primary and secondary.
The leading causes of obesity are overeating and a sedentary lifestyle. It is easy to gain extra pounds, but it is much more difficult to get rid of the fat deposits and habits of overeating. Some people eat more in stressful situations. Others overeat because of a bad mood, longing and loneliness. Someone imperceptibly eats up a mountain of food, sitting comfortably in front of the TV. Someone creeps up to the fridge at night. And gourmets like to eat delicious food.
If the person spends most of the day sitting and does not run marathons or sweats in the gym, then sooner or later his weight will exceed all reasonable limits.
Age plays an essential role in the development of obesity. Doctors believe that the older a person becomes, the more likely that he would gain excess weight, what is due to a slowing of metabolism and a violation of the activity of the appetite centre in the brain, that is, more food is needed to suppress hunger with ageing.
There is such a thing as secondary obesity. As a rule, extra calories have nothing to do with it. Endocrine(or hormonal) diseases are the causes of obesity as found. Obesity accompanies Isenko-Cushing’s disease, hypothyroidism, and the like. Also, a distinct increase in body weight occurs when taking certain medications: prednisolone, dexamethasone, etc. Besides, the tendency to obesity can be inherited.
With primary obesity, constant overeating leads to disruption of the appetite centre in the brain, and the usual amount of food eaten can no longer suppress the feeling of hunger, and a person has to eat more and more. Fat deposits store excess calories as if for stock, which leads to an increase in the amount of fat in the body, that is, to the development of obesity
