A, affect the psychological development of children Children’s psychological development is still immature, most children want to look beautiful and fit, pay great attention to their external image, and obesity precisely affects this love of beauty psychology. Students often give obese children nicknames, such as: “little fat pig”, “big dog bear”, “fat dun”, etc. This will bring serious impact on the self-esteem of obese children, easy to become Isolated, few words, strange personality, and the surrounding classmates do not get along well. Second, the impact on children’s intelligence intelligence is a person’s memory, thinking, observation, imagination, behavior, expression and other social and practical skills of the synthesis. The brain is the material basis of intelligence, therefore, the human intelligence how, and the functional state of the brain is closely related. Seriously obese children, the brain cortical sulcus becomes shallow, the gap becomes narrow, thus affecting their IQ. Third, obese children are prone to disease obese children, there are a lot of although eat a lot, but often get sick, injections and medication is a common occurrence. This is because the obese children’s body B lymphocyte function to reduce the number of reduced antibody secretion, the ability to remove antigens is weakened; also, high sugar diet will also reduce the biological function of protein, naturally also affect the function of the immune system; obese children reduce activities, especially outdoor activities, so encounter cold stimulation, it is easy to get a cold. These factors can cause the immune function of obese children to decline, easy to induce infectious diseases. Fourth, affect the life expectancy of people Some information shows that obese children on average to shorten the life expectancy of 10 years, mainly refers to childhood obesity, for middle and old age disease laid the foundation. Why obese life expectancy will be shortened, the mortality rate is higher than normal people? It is mainly because of the complication of the main diseases that threaten human health. These diseases in general can be summarized as coronary heart disease, hypertension and hyperlipidemia, diabetes. In the case of stroke, the number of obese people suffering from the disease is several times higher than that of normal weight people, which will undoubtedly affect lives. In the obesity number increase at the same time, cardiovascular disease has become a hidden danger to the health of all people. Fifth, the impact on the reproductive system of children Obesity on the reproductive system of children’s impact is mainly manifested in precocious puberty, poorly developed sexual organs, sexual dysfunction, etc.. Severe obesity children’s testes and ovaries of the normal development may be obstructed, incomplete, low levels of sex hormones in the body, resulting in adult secondary sexual characteristics of poor development, or even sterility. Sixth, children’s obesity and coronary heart disease obesity itself is due to increased synthesis of fat caused by. Obese children’s plasma triglycerides, cholesterol, low-density lipoprotein, very low-density lipoprotein are increased, and high-density lipoprotein reduced, easy to lead to atherosclerosis and coronary heart disease. High-density lipoprotein can prevent atherosclerosis and coronary heart disease, its decline will make the incidence of coronary heart disease greatly increased. Seven, children’s obesity and hypertension obese children due to excessive expansion of adipose tissue, resulting in the expansion of the vascular bed, systemic blood volume increases, blood vessels are prone to sclerosis. In addition, obese children due to excessive lipids, deposited in the blood vessel wall, resulting in damage to the blood vessel wall, hardening, elasticity reduction, hypertension naturally followed. Eight, children’s obesity and diabetes diabetes and obesity are closely related. Obese children generally like to eat sweets, the higher the blood sugar, the more insulin secretion, the faster the processing of sugar, stored in the form of fat. Long-term overload state will make the pancreas fatigue, insulin secretion is insufficient, resulting in increased blood sugar, and even the occurrence of diabetes. Nine, children’s obesity and fatty liver The incidence of fatty liver in obese children is significantly higher than that of children with normal weight, and the impact on health is much more serious than that of fatty liver in adults. Ten, children’s obesity and ventilation deficiency Obese children’s whole body fat increased significantly, the heart is full of fat around, the movement of respiratory muscles is restricted, the increase of fat in the abdominal cavity to increase the abdominal pressure, all this affects the normal pulmonary ventilation function, manifested as dizziness, weakness, fatigue, drowsiness, etc.. The reduced respiratory efficiency results in sustained pulmonary hypertension, which can eventually lead to pulmonary heart disease.
