Obesity has become a global public health problem. According to the International Obesity Task Force (TOTF), obesity will become the biggest threat to human health and life satisfaction in the new century. There is no denying that obesity has been called some diseases and has been a serious threat to our health. So what exactly is obesity? Obesity is a chronic social disease. The intake of calories in the body is higher than the consumption, resulting in excessive fat accumulation in the body, resulting in overweight and bloated posture. The actual measured weight exceeds the standard weight by more than 100%, and the fat percentage (F%) exceeds 30% is called obesity. Popularly speaking, obesity is excessive accumulation of fat in the body.
Obesity refers to a certain degree of significant overweight and fat layer is too thick, is a state caused by excessive accumulation of body fat, especially triglyceride. Excessive food intake or metabolic changes lead to excessive accumulation of fat in the body resulting in excessive weight gain and cause human pathology, physiological changes or latent.
Primary is related to family, personal living habits, socioeconomic development, cultural background, light environment, poor eating habits, physical inactivity.
Obesity degree = (actual weight – standard weight) ÷ standard weight ×±100%
Obesity within ±10% is considered normal moderate. Obesity levels above 10 percent are considered overweight. Obesity levels above 20 to 30 percent are called mild obesity. Obesity levels above 30% to 50% are considered moderate. Obesity levels above 50% are considered severely obese. Obesity of less than -10% is called underweight. Obesity is less than -20% or more, called wasting.
(1) Genetic and environmental factors
(2) Changes in substance metabolism and endocrine function
(3) Too much energy intake, reduced consumption
(4) increased number and hypertrophy of adipocytes
(5) Neuropsychiatric factors
(6) Living and eating habits
The harm of obesity to human body: increase the risk of cardiovascular disease; Obesity affects the function of the digestive system; Obesity affects the function of endocrine system; Obesity increases the risk of cancer; In addition, there are joint soft tissue injury, decreased reproductive ability and psychological disorders.
There are two types of simple obesity:
Physical obesity: cause: congenital. Metabolism of material inside body is slower, the speed of material synthesis is greater than the speed of decomposition. What you see: Fat cells are large and numerous, all over the body.
Acquired obesity: Cause: Caused by overeating. Food in sweet, rich food. More fat is spread around the torso.
Diencephalic obesity: this is the consequence of diencephalic organic disease. In addition to obesity, there are also endocrine dysfunction manifestations, such as appetite fluctuation, abnormal sleep rhythm, easy changes in body temperature, blood pressure, pulse, decreased sexual function, diabetes insipidus, etc. Obesity is only one component of diencephalon syndrome.
Obesogenic impotence: this disease is thought to be the hypothalamus pituitary adjacent due to infection, tumor or trauma caused by abnormal appetite, fat metabolism, gonadal function. The main manifestations are obesity and lack of genital development.
Pituitary obesity: True pituitary obesity is seen in Cushing’s syndrome with active basophils and acromegaly with eosinophils.
Thyroid obesity: Patients with myxedema usually have a bloated appearance rather than obesity. The fat is calm and obvious in the neck, and the face is full moon face.
Hypercortisolism: also known as Cushing’s syndrome, it can be caused by a number of causes. The clinical manifestations were complex. There may be early symptoms similar to hyperthyroidism, there may be cases dominated by psychiatric symptoms, or may resemble simple obesity.
Pancreatic obesity: disease of the pancreas can lead to diabetes and beta cell tumor of the pancreas in obese individuals
In addition, there are other diseases can lead to pathological obesity, such as cranial plate hyperplasia, bilateral polycystic ovary syndrome.
