The progress of society and the improvement of living standards make people’s requirements for quality of life reach a new height, obesity is no longer an unfamiliar topic. Weight control has been from the young people love beauty requirements into the pursuit of health signs, and has reached the degree of fat talk, parents worry about children overweight, wife complained about the husband is too fat, the elderly are not proud of the general belly. Some years ago, Dr. Eckel of the American Dietetic Association said, “obesity has not only affected the appearance and should be blamed for the problem, obesity is about to become a dangerous plague, such as hypertension and high blood cholesterol, is a chronic disease.” Not surprisingly, we now refer to the combination of obesity-centered hypertension, hyperlipidemia, hyperglycemia and accompanying other metabolic disorders collectively as the metabolic syndrome, a good illustration of where the dangers of obesity lie. Although weight control and health protection have been accepted by people, but because people’s demand for health and body shape is increasing and driven by economic interests, obesity drugs and treatment methods are also emerging, five or eight people, so that people fall into a kind of dazzling, at a loss. Often hear people lose weight, but the physical strength decline, body discomfort, and even go to the hospital for medical treatment. In this need to emphasize that obesity is a multi-factor chronic disease, weight loss is a scientific behavior, not arbitrary, everyone can be, since obesity is a disease, we must treat it with a scientific attitude, according to the cause, disease and different groups of people to take different treatment measures, so as to both reduce weight, but also to protect health, the following from several aspects of the different groups of people to talk about weight loss strategies: a, adolescent obesity Adolescent obesity has become a problem that can not be ignored today, and in children also found in the past rarely seen type 2 diabetes, hyperlipidemia, fatty liver and other adult diseases, these diseases are closely related to the occurrence of obesity. The occurrence of obesity in adolescents is partly due to genetic factors, but mostly due to poor lifestyle. The change of diet structure, the popularization of computers and video games, and the reduction of activities are largely responsible for the current consequences of obesity. Children’s obesity treatment should focus on controlling the weight continue to increase abnormally, such as educating parents and children to develop reasonable eating habits, do not be partial, eat more high-quality protein (such as dairy, seafood) and vitamin-rich, multi-fiber food, to ensure that the nutritional composition is reasonable, moderate calories, avoid eating too much high-calorie, high-fat, high-carbohydrate food, especially fast food, fried snacks Avoid excessive consumption of high-calorie, high-fat and high-carbohydrate foods, especially fast food, fried snacks and carbonated drinks. However, children are in the growth period, weight should match the height increase, can not simply restrict the diet and nutrition intake, especially the method of reducing the number of meals is not desirable for children. It is worth noting that you can not talk about fat in front of the child, so not only physiologically, but also psychologically will bring obstacles to the child. Parents take their children to do more outdoor activities, encourage children to come and play with each other, appropriately reduce the burden of study, more communication with people and society, rather than facing books and screens every day. For obese children, they are relatively more inactive, so they should consciously arrange more physical activities for them, such as acting as liaison at school, doing more housework at home, walking to school as much as possible, going upstairs without taking the elevator, doing some fitness activities after meals and studying for a period of time, and at the beginning, adults should supervise them or let them write diaries, and they can stick to them after they have formed the habit. Unless serious obesity and other causes of morbid obesity, children’s obesity does not advocate drug treatment. Some diseases such as hypothalamus, pituitary disease, thyroid disease, gonadal disease, liver disease can lead to obesity, such as adolescents with dysplasia, gynecomastia, acanthosis nigricans, purple lines on the abdomen, etc. Girls with abnormal menstruation should draw the attention of parents and go to the hospital in time to relieve the causes of the disease. In particularly obese and appear lipid metabolism, glucose metabolism disorder obese adolescents, should be under the guidance of the doctor appropriate application of some appetite suppressants or biguanides, in some children with low thyroid function, can apply the appropriate amount of thyroid hormone. Second, adult obese young people because of their higher requirements, grasp knowledge faster, more activities, and social activities also make them pay more attention to the quality of life, so the obesity of this crowd is not the main problem, instead, we should pay attention to the problem of overkill, women’s aesthetic requirements and physiological fat content more, so they become the most concerned about obesity crowd, the most urgent requirements, girls to bone Beauty is proud, but this can often be another pathology. In the female population of weight loss treatment there are many misconceptions, lack of science. For example, weight loss by fasting, the thinner the more beautiful, excessive exercise, and so on, has led to anorexia, menstrual disorders, malnutrition and other weight loss complications specific to women. From a physiological point of view, women have more fat than men, and the distribution of parts is different from men, and adipose tissue is an important endocrine organ, which can secrete many essential hormones, such as leptin, lipocalin, etc., which have an important role in human development, fertility and normal metabolism, so the requirement for women is an even distribution of fat, BMI between 19-23 is the ideal body weight. Encourage normal eating and reasonable exercise, and it is more beneficial for women to eat more dairy and soy products because soy products contain phytoestrogens, which can supplement the lack of estrogen and its symptoms caused by ageing. Adult obesity is worthy of attention in the crowd is middle-aged people, in the career success at the same time, often burdened with career, family double pressure, often in forgetful social activities, do not care about their own body, with the growth of age, often have to pay a heavy price, male obesity is more harmful than female obesity, treatment is far from enough attention. Big belly, general belly is considered a sign of successful men, the expression of wealth. Do not know it is this kind of obesity to the health of the greatest harm, we call abdominal obesity, visceral obesity, also called apple type obesity. The essence is the increase of visceral fat, mostly caused by insulin resistance, in these people hyperlipidemia, hyperglycemia, hypertension, heart disease, fatty liver incidence increased significantly, so the treatment is more complex, to be integrated treatment, depending on the person. Simple obesity to adjust the lifestyle, exercise into the life, step with car, face to face instead of electric talk, will play a significant effect. In terms of treatment, the first thing to emphasize is adjusting the lifestyle, eating regularly and quantitatively, and exercising appropriately. The moderate obesity with hyperphagia and lack of exercise can be considered to apply appetite suppressing drugs and drugs to increase metabolism, and weight reduction of about 5%-10% is appropriate, but weight loss drugs are not easy to apply for a long time. For patients with mainly centripetal obesity, accompanied by hypertension, hyperlipidemia and hyperglycemia, it is likely to be metabolic syndrome, necessary examination should be carried out, and a series of metabolic abnormalities caused by hyperinsulinemia and fatty liver should be controlled by drugs, and reasonable application of lipid-lowering drugs and insulin sensitizers will have good effect. Patients with metabolic disorders are often accompanied by hypothyroidism, which can also cause weight gain and obesity, and can be appropriately supplemented with thyroxine to relieve symptoms and control weight. Some middle-aged women due to estrogen deficiency and menopause can also cause obesity and water and sodium retention, can add a small amount of diuretic drugs to reduce edema, and the use of hormone replacement therapy, can also reduce weight. Body mass index is the standard for judging the degree of obesity, expressed by the ratio of height (m) and weight (kg) squared, more than 35 we call super obesity or morbid obesity, for this kind of super obesity at home and abroad are currently carried out surgical treatment, the effect is remarkable, and can alleviate other complications, to achieve a multi-benefit effect, can be selected according to the situation of gastric balloon placement, gastric bundling and gastric bypass surgery. It has been reported abroad that after gastric bypass in obese diabetic patients, blood glucose can be normalized and no medication can be used for a considerable period of time. Shanghai has several hospitals also carried out the obesity surgery treatment, have achieved a good effect. Third, old age obesity has a saying called “money is difficult to buy old to be thin”, from a side also shows that old age obesity is not good for health, a number of studies also proved this point. Research shows that the obese people over 60 years of age has reached 1/4, the incidence of diabetes, hypertension, cardiovascular disease, gout, arthritis and other diseases in the elderly obese people is significantly higher than the non-obese group, and heart attacks, strokes and other morbidity and mortality also increased. However, the elderly often pay less attention to the problem of obesity, rarely go to the hospital because of obesity problems, and mostly seek medical consultation only when other diseases appear. There are many causes of obesity in old age, such as postmenopausal obesity in old women, obesity caused by depression in widows and orphans or obesity caused by excessive diet and inactivity, so it is also necessary to emphasize reasonable diet with appropriate exercise (such as walking and climbing stairs) in old people, and at the same time be cautious when applying diet drugs, avoid applying diet drugs that inhibit central nervous system and affect cardiovascular, and encourage old people to develop more tea and water Encourage the elderly to develop the habit of drinking more tea, and drink a small amount of alcohol. In terms of drugs, lipase inhibitors or biguanides can be used, which have a certain effect on the control of obesity and other metabolic abnormalities. However, it is not easy for the elderly to reduce weight slowly, not easily, not easily, as long as they do not maintain a continuous increase in weight will receive good results. Can not deliberately go to lose weight and affect health, it is reported that the mortality rate after heart attack in wasted patients is significantly higher than obese patients, so the understanding of obesity can not be generalized.
