First, the change of adipose tissue (I) easy to occur during the period of obesity in human life, there are three periods of the most prone to obesity in infants and young children before the age of.5 years of age; youth development period; after the age of 40.
Pregnancy, lactation and menopause most prominent. Infant obesity is the least noticeable. Because usually think the baby more fat said better, nutrition, feeding method.
(two) adipose tissue of normal adipose tissue was mainly composed of fat cells, a few fibroblasts and a small amount of collagen. Adipose tissue contains fat in the fat cells, under the influence of nervous and humoral factors, neutral fat synthesis and catabolism is very active. Adipose tissue contains an average of about 80% fat, water content of about 18%, containing protein of about 2%. Deep fat tissue than subcutaneous adipose tissue water content slightly more. Obese adipose tissue water content more than thin. Obese people lose weight, reduce adipose tissue, adipose tissue water content is also reduced.
(three) adipose tissue changes the size of fat cells in different parts of subcutaneous adipose tissue. Normal human subcutaneous fat cells average length of about 67 to 98 microns, a fat cell fat content about 0.60 micrograms, obesity, fat cell hypertrophy, subcutaneous fat cells up to 127 ~ 134 micron, increased 50% to 100%, each fat cell fat content of about 0.91 to 1.36 micrograms. When the occurrence and development of obesity quickly, generally only fat cell hypertrophy, when slow long-term obesity, fat cell hypertrophy, but also increased the number of. The number of fat cells in a normal human body can be increased from (2.68 +. 0.18) x to + (+ + 7.70 +) x 1010, and the number of fat cells increased by a factor of 3 (). It is generally believed that fat cell hypertrophy and hyperplasia are not consistent with the occurrence and development of obesity. Normal female fat cells more than men. In the past, there was no history of obesity. Adult patients with serious long-term obesity, fat in fat cells with large, the number of fat cell proliferation. Weight at birth, the baby was significantly obese, obese youth development, the majority of adults to obesity. This adult obese patients, fat cell hypertrophy and proliferation at the same time, the treatment of the most difficult to obtain curative effect and consolidate curative effect. It can be seen whether obesity is the critical period of fat cells in infancy. At this age, it is more suitable for fat cell proliferation than other age groups.
(four) the cause of fat deposition is eating too much sugar and fat without a suitable energy consumption. Eating normally, but the use of fat deficiency and excessive fat production. Therefore, regardless of protein, fat or sugar, such as excess heat, remove the heat consumption, the excess heat is stored in the body. Due to the limited storage energy of protein and sugar, most of the excess heat is stored in subcutaneous tissue in the form of fat. The obese and normal people have obvious difference in metabolism: the same diet, obesity and metabolism than normal hyperthyroidism; obesity at rest, or walk when the energy consumption is less than normal; obesity in the inactive state of weak cold reaction, as well as normal people can increase the metabolic rate. In daily life, activities of people vary very much, need to heat also is different, less daily only 6 million 278 thousand coke (1 million 500 thousand cards), more in the 3 million card above. However, the body weight can be kept constant. The main reason is that the neuroendocrine system is involved in the regulation of human activity, food intake and metabolism. Secondary obesity caused by pathological changes is mainly due to the disorder of the regulation of fat and carbohydrate metabolism.
