&# 8203;&# 8203;&# 8203;&# 8203;&# 8203; The human environment is prone to obesity. Although eating too much and not enough exercise are the reasons for the prevalence of obesity, the deep reason is likely to be the complex combination of globalization, industrialization and other social, economic, cultural and political factors. The harm of obesity to human beings is far more than what we see on the surface. Obesity can create various complications. Research in Taiwan shows that 22% of obese children suffer from hypertension and 16.8% have abnormal glucose tolerance.
According to a recent report on the website of Newsweek, human beings have become fatter and fatter in the past 50 years. Scientists believe that this is largely due to our environment. A new study published in the British Medical Journal warns that the so-called 'obesity' environment will increase our chances of unhealthy body mass index (BMI) from our womb to our death&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;
A large amount of evidence shows that there is a J-curve relationship between body mass index and mortality. When the body weight is too low, the death caused by respiratory diseases and low birth weight increases; When weight is too high, the death of obesity related diseases increases.
Ten hazards of human obesity
Many people should know that obesity will do harm to their health. Here are the top ten hazards brought by obesity to mankind.
1. Obese people are prone to cancer
According to epidemiological findings, obese women are more likely to suffer from endometrial cancer and postmenopausal breast cancer, while obese men are more likely to develop prostate cancer. And as long as they are obese, both men and women are more likely to suffer from colon and rectal cancer. The more severe the degree of obesity, the higher the prevalence of these cancers.
2. Lead to various vascular diseases
Obesity can easily lead to various vascular diseases. In addition to the excessive accumulation of subcutaneous fat, the viscera and blood vessels all over 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 seriously harmful to health and life. Research data show that the incidence rate of hypertension in obese people is 1.5 to 3 in normal people. Moreover, the higher the obesity, the higher the incidence rate of hypertension, the higher the blood pressure. The incidence rate of hypertension in severely obese people is above 50%. On the contrary, if various weight loss measures are taken to reduce weight, the blood pressure will drop accordingly.
3. It is easy to induce diabetes.
Although obesity is a direct cause of diabetes, its induced effect on diabetes is not negligible. Many data confirm that the more obese, the higher the incidence rate of diabetes. At present, in some economically developed countries, the most common diseases caused by obesity are diabetes. About 1/3 of adults with type 2 diabetes are obese. Almost all obese people have elevated fasting blood glucose in varying degrees.
4. It is easy to cause motor system diseases
The excessive weight gain of obese people is an additional burden on the motor systems such as bones and joints, especially on the spine and lower limbs. Bones, joints and other tissues support excessive weight for a long time, just like carrying excess things every day. Over time, they will inevitably become ill from accumulated fatigue, arthritis, muscle strain or spinal nerve root compression, causing pain in the waist, legs, shoulders and back, and even joint deformation, which will seriously affect limb activity.
5. Lead to dyslipidemia
Obese people, especially those with abdominal obesity, are more likely to show hypercholesterolemia, hypertriglyceridemia, abnormal increase of low-density lipoprotein and very low-density lipoprotein, but decrease of high-density lipoprotein. The reasons why obese people are prone to hyperlipidemia are not very clear. The possible reasons are as follows: first, eating more fat, second, more fat storage in the body, third, hyperinsulinemia can increase blood lipids, and fourth, there is a problem in the clearance of blood lipids.
6. Increased risk of hypertension
Obesity is closely related to hypertension. Among obese people aged 40-50, the incidence of hypertension is 50% higher than that of non obese people. A moderately obese person is more than five times as likely to have hypertension as a normal weight person and more than twice as likely as a slightly obese person.
7. Increased cardiac load
It was found that the incidence of angina pectoris and sudden death increased fourfold in obese people. This shows that obesity will certainly increase the burden on the heart and cause heart damage. The heart of a normal human body is like a water pump, constantly contracting and relaxing, maintaining the circulation of blood. Obese people store too much fat in their blood, so the total amount of blood increases a lot, and the heart will increase the strength of contraction accordingly. When the heart is overwhelmed, it can no longer pump blood effectively, resulting in the accumulation of blood in the cardiovascular system, and even obvious heart failure.
8. Cause fatty liver
About half of obese people have fatty liver. The liver is the place where triglycerides are synthesized, but there is not much room in the liver to store it. In obese people, the balance between triglyceride synthesis and transport is out of balance. Obese people have more fatty acid intake, so the liver also has more triglycerides. Large amounts of triglycerides accumulate in the liver. As a result, fatty liver was formed.
9. Cause bone and joint diseases
There are mainly three kinds of bone and joint diseases that may be caused by obesity: osteoarthritis, diabetic osteoarthropathy and gouty osteoarthropathy. One of the most common and harmful is osteoarthritis. Osteoarthritis caused by obesity mainly affects knee joint, followed by hip joint and finger joint.
10. Hinder nutrient absorption
Obesity is a nutritional disorder. For a long time, some people always think that as long as they grow fat with a round waist, they mean good nutrition. In fact, obesity does not mean good nutrition. Like weight loss, it is caused by nutritional disorders. The only difference between them is the amount of fat stored in the body. Obesity is not only the excess of body fat, but also the lack of some nutrients. For example, many obese children are often accompanied by the deficiency of trace elements such as iron and calcium, resulting in a variety of nutritional deficiency diseases such as iron deficiency anemia and chondropathy.
