With the improvement of living standards, people s nutritional status has been improved, and blessed people are increasing. The rapid rise of the Obesity Army has brought new disasters to people s health: the incidence of heart disease, hypertension and diabetes in obese people is three times that of those of normal weight: the incidence of arteriosclerosis is that of normal weight 2-3 times; the incidence of cancer is twice that of normal weight. Obesity can also cause a variety of diseases such as stroke, hyperlipidemia, respiratory diseases, skin diseases and so on. In addition, obesity also reduces human life … The harms of obesity can be described as quite a lot. Let s take a look with Xiaobian to see what are the harms of obesity!
Obesity refers to a certain degree of obvious overweight and fat layer is too thick, is a state caused by excessive accumulation of body fat, especially triglycerides. It does not refer to a simple weight gain, but a state of excess fat tissue accumulation in the body. Due to excessive food intake or changes in body metabolism, excessive fat accumulation in the body causes excessive weight gain and causes pathological, physiological changes or latency of the human body.
Obesity is a nutritional disorder. For a long time, some people always think that as long as they grow round and fat, it means good nutrition. In fact, obesity is not the same as good nutrition. It is caused by nutritional disorders, like weight loss. The only difference between the two is how much fat is stored in the body. Obesity is not only an excess of body fat, but also a lack of certain nutrients. For example, many obese children are often accompanied by deficiencies in trace elements such as iron and calcium, which cause a variety of nutritional deficiencies such as iron deficiency anemia and chondropathy.
Obesity can easily lead to various vascular diseases. In addition to the accumulation of subcutaneous fat in obese people, the internal organs and blood vessels throughout the body are also full of fat, so it is easy to cause a variety of vascular diseases, especially cardiovascular and cerebrovascular diseases that are serious to health and life. Relevant research data show that the incidence of hypertension in obese people is 1.5 to 3 in normal people. Furthermore, the higher the degree of obesity, the higher the incidence of hypertension, and the more obvious the increase in blood pressure. The incidence of hypertension in severely obese people is as high as 50%. On the contrary, if various weight loss measures are taken to reduce weight, blood pressure will be reduced accordingly.
Although obesity cannot be said to be the direct cause of diabetes, its evoking effect on diabetes is not to be ignored. Many data confirm that the more severe the obesity, the higher the incidence of diabetes. At present in some economically developed countries, the most common disease caused by obesity is diabetes. About one-third of adults with diabetes are obese. Almost all obese people have varying degrees of fasting blood glucose.
Excessive weight gain in obese people is an additional burden on the bones and joints, especially the spine and lower limbs. Bone, joints, and other tissues support excessive weight for a long time, as if carrying extra things every day. Over time, it will inevitably become overworked, arthritis, muscle strain or spinal nerve root compression will occur, causing pain in the waist, legs, shoulders, and back, and even joint deformation Seriously affect physical activity.
Obese people, especially those with abdominal obesity, are more likely to show hypercholesterolemia, hypertriglyceridemia, low-density lipoprotein, and very low-density lipoprotein than normal people, while high-density lipoprotein decreases. The reasons why obese people are susceptible to hyperlipidemia are not yet clear. The possible reasons are as follows: one is eating more fat, the other is storing more fat in the body, the third is hyperlipidemia which can increase blood lipids, and the fourth is blood lipids. There is a problem with the removal.
Obesity is closely related to hypertension. Among obese people aged 40-50 years, the risk of hypertension is 50% higher than that of non-obese people. A moderately obese person is more than five times more likely to develop hypertension than a normal- weight person, and more than twice as likely to be mildly obese.
Some people have found that the incidence of angina pectoris and sudden death in obese people has increased by 4 times. This shows that obesity will definitely increase the burden on the heart and cause heart damage. The normal human heart is like a water pump, which constantly contracts and relaxes, maintaining the circulation of blood. Because obese people store too much fat in the blood, the total blood volume increases accordingly, and the heart will increase the contraction force accordingly. When the heart is overwhelmed, it can no longer effectively pump blood, causing the blood to accumulate in the cardiovascular system, and even severe heart failure can occur in severe cases.
About half of obese people have fatty liver. The liver is a place where triglycerides are synthesized, but there is not much extra space in the liver to store it. In the obese people, the balance between triglyceride synthesis and transport is out of balance. Fatty people have more fatty acid intake, so the liver also has more triglyceride synthesis. Large amounts of triglycerides accumulate in the liver. As a result, fatty liver is formed.
There are three main types of osteoarthritis that obesity can cause: osteoarthritis, diabetic osteoarthropathy, and gout osteoarthropathy. Among them, osteoarthritis occurs most frequently and is most harmful. Osteoarthritis caused by obesity mainly affects the knee joint, and secondly it can affect hip joints and finger joints.
According to the results of epidemiological investigations, obese women are more likely to have endometrial cancer and postmenopausal breast cancer, and obese men are more likely to have prostate cancer; and as long as they are obese, both men and women are more likely to develop colon cancer and rectal cancer. The more severe the degree of obesity, the higher the prevalence of the above cancers.
