In the past, many people did not think that obesity was a bad thing, or a disease, and even some people regarded obesity as an expression of "health", a sign of improved living standards, and a symbol of wealth. However, now as the health problems caused by obesity become more and more serious, people are gradually realizing that obesity is no longer a symbol of wealth, but a "petri dish" of disease, and at the same time, from the death spectrum, the obesity death rate is comparable to cancer, so it is also likened to "rich cancer"! [1]
So let's take a look at the harm that obesity brings to us today:
First, obesity can cause immeasurable harm to various systems of the human body. The cardiovascular system bears the brunt of this, and studies have confirmed that obesity is a high-risk factor for cardiovascular diseases such as coronary atherosclerosis, heart failure, sudden cardiac death, and atrial fibrillation. Obesity and "three highs (hypertension, hyperglycemia, hyperlipidemia)" are also "good friends" who walk hand in hand, and patients with digestive and metabolic diseases such as obesity and diabetes, fatty liver, hyperlipidemia, and hyperuricemia are becoming more and more common.
For the respiratory system, adipose tissue accumulates in the abdomen or diaphragm, causing the diaphragm to lift up, the tidal volume to decrease, the lung volume to decrease, and in severe cases, the volume of oxygen to decrease, and even hypoxemia.
For the immune system, excessive obesity is associated with damage to the immune system. In clinical and epidemiological investigations, obesity has been found to be associated with some infectious diseases, because obese patients can change some inflammatory factors so that the phagocytic function of macrophages decreases, so they are more susceptible to erysipelas, enteritis, and perianal abscess. Infectious diseases such as skin boils.
At the same time, obesity has become a dangerous source of "cancer" for the deadly killer of human beings. Data show that for every 5 kg/m2 increase in BMI in men, the risk of esophageal adenocarcinoma increases by 52%, the risk of thyroid cancer increases by 34%, colon cancer increases by 24%, and the risk of kidney cancer increases by 24%; For every 5 kg/m2 increase in bMI in women, the risk of endometrial cancer increased by 59%, the risk of gallbladder cancer increased by 59%, the risk of esophageal adenocarcinoma increased by 51%, and the risk of kidney cancer increased by 34%. Obesity not only increases cancer risk, but also its mortality rate, and obesity has a linearly increasing relationship with the risk of cancer death. Obesity can also increase the burden on bones and joints, resulting in bone and joint lesions. [1]
Secondly, from the psychological level: the anxiety and depression psychological problems of obese people are more prominent, and they often have inferiority and depression because of their large body size or eye-catching weight figures. Obese people are usually very concerned about what others think of their appearance due to their overweight or obesity, have a high level of self-esteem, and sometimes a casual little joke may be unbearable for them. Most obese people are usually introverted, timid, and do not like to communicate with people, they just want to hide themselves in their usual study or work, and strive to reduce their sense of existence. And with the change of social aesthetics, obese people are more likely to suffer ridicule or discrimination. Therefore, they are more likely to have interpersonal problems such as hostility and loneliness. [2] Especially for children, psychological problems such as inferiority complex depression caused by obesity have a serious impact on their future values and can have a huge impact on themselves, their families and society.
Finally, from a social perspective: the survey shows that the number of obese people aged 18 to 69 in China in 2018 was about 85 million, of which about 48 million were men and about 37 million were women. By 2030, there will be 800 million people on the mainland who are overweight or obese. This huge number not only brings us a visual impact, but also brings a great burden to our society. Due to the increase in obese people, a series of diseases caused by obesity will also increase year by year, which undoubtedly brings huge pressure to our medical industry, the input of medical costs will be greatly increased, then the government's cost of science and technology, education will also decline; the increase in obese people will cause a large number of losses of social labor, some industries with higher physical requirements may have a shortage of talents, such as heavy physical labor work may be unattended, people's economic strength and purchasing power will be greatly reduced. At the same time, a series of psychosocial problems caused by obesity will also become the "murderers" who affect the happiness of our people. [3]
Today, in the 21st century, obesity has become a major "enemy" that threatens our physical health, and attaching importance to obesity, learning from obesity, and staying away from obesity can make us live a happy life.
