Do you remember that in mid-February we started the autopsy work on the remains of patients with new crown pneumonia? Now the autopsy report has been released, the results show that: the new crown pneumonia mainly caused deep airway and alveolar damage characterized by inflammatory reaction, lung fibrosis and solid lesions are not as serious as those caused by SARS, but the exudative reaction is more pronounced compared to SARS. It is clear that the neocoronitis lesions throw focus on the lungs, and evidence of damage to other organs still needs further investigation. How important are the human lungs? If someone asks you: “What is the most important organ of the human body?” I believe the first thing that comes to mind is either the heart or the brain, and indeed, among the diseases that have been identified in humans, those involving the brain and the heart are generally more serious and easier to be taken seriously. The heart is responsible for pumping blood and the lungs are responsible for the ability to inhale oxygen, both of which can be directly related to the activity of organs and muscles throughout the body. Therefore, in addition to the heart, the lungs are also an important component of the whole. Therefore, the term “cardiorespiratory fitness” is one of the most common health-related terms we hear. Who are the people whose cardiopulmonary function is weaker than normal? The heart corresponds to blood and the lungs correspond to qi. The Chinese idiom “血气方刚刚” describes young people who are very energetic, and we can also understand that young people in general do not have poor cardiorespiratory fitness. In daily life, the body’s high-intensity exercise depends on strong cardiopulmonary function as support. And usually lack of exercise in the obese people as well as the heart of the elderly, chronic disease patients have become a weak cardiopulmonary function on behalf of the crowd. Especially patients with severe obesity, China has become the world’s largest number of obese people in the population base under the premise of a large number of obese people in the population of our country is also quite high If you have paid attention to the epidemic before the patient news, you will find that these categories of people are also exactly the main part of the new Coronavirus Pneumonia severe and high-risk patients. Therefore, cardiopulmonary function as an important part of the test of health should not be ignored. How can obese people improve their cardiopulmonary function? Compared to ordinary people, obese people are more likely to be out of breath during exercise, which is a direct indication of weak cardiopulmonary function. As weight rises, cardiorespiratory function will further decline, so obese people to improve cardiorespiratory function priority to do is to lower the weight, so that all aspects of the body’s function back to normal. For the less obese people, you can also achieve the effect of weight loss through appropriate exercise. However, for people with severe obesity (BMI ≥ 32), exercise to lose weight can achieve little effect, but importantly, it may also add more burden to the body leading to other health risks. Therefore, people with severe obesity are better suited for a “special” approach to weight loss, such as bariatric surgery. Unlike other weight loss surgeries that aim to improve body shape, this surgery is performed by realigning the body’s internal gastrointestinal tract, which naturally results in a more drastic change in the person’s diet after the surgery. For example, the amount of food eaten is decreased, as is the amount of nutrients the body draws from food. By allowing one’s body to re-adapt to the post-surgical environment, significant weight loss will typically occur within six months. Some people may feel that this method is too slow to lose weight, but one of the advantages of weight loss surgery is that it is stabilizing, with a very low chance of weight regain. Improving your cardiorespiratory fitness can save you from many minor ailments, and perhaps for many young obese people, a change in appearance is more important than physical health. While the weight loss surgeries mentioned above are aimed at health, they are also a way to improve the internal condition of the body through the surface of weight loss. In other words, what’s not to like about a method that does both aesthetics and health at the same time.
