In the past, when medical conditions were not developed, infectious diseases caused the majority of deaths. However, with scientific progress, their mortality rate has decreased a lot. Instead, non-contagious diseases such as cardiovascular diseases, respiratory diseases, and physiological diseases have become the main factors of death. Nowadays, many studies have found that the so-called “non-communicable diseases” are related to “contagious”. The most incredible thing is that obesity and diabetes are also contagious. Gut flora may be an important factor in the social transmission of non-communicable diseases In a recent article published in the leading academic journal Science, scientists have proposed the idea that many diseases that are usually “non-communicable”, such as obesity, diabetes and cardiovascular disease, may also be transmitted from person to person through microorganisms. These scientists provide evidence that the various bacteria, fungi and viruses that live with us in the human gut may be an important factor in the social transmission of non-communicable diseases. Obesity is a major risk factor for many NCDs The article highlights that “obesity is a major risk factor for many NCDs” and there is growing evidence that “microbes are an important factor in obesity.” The study authors cite a number of examples to illustrate the relationship. For example, one study that lasted 30 years and tracked more than 12,000 people found that if you had an obese friend, you were 57 percent more likely to become fat yourself. Another study of U.S. military families showed that being stationed in areas with higher rates of obesity increased their body mass index; conversely, being stationed in areas with lower rates of obesity decreased BMI. For type 2 diabetes, which is particularly affected by obesity, data show that within a year after one person in a couple is diagnosed with type 2 diabetes, the spouse is also likely to show a trend toward type 2 diabetes, and this trend can be maintained for more than three years. What should I do if I have a sugar-fat person around me? Even if you are around someone who is obese, you do not have to worry too much, you can avoid obesity by making appropriate lifestyle changes. Dr. Dai Xiaojiang, a bariatric and diabetic surgery specialist at Youdao Group, reminds that it is important to monitor weight changes regularly to detect any abnormalities in your metabolic system and eating habits as early as possible. Second, keep your mouth shut and control your intake. Eat less or no foods high in sugar, fat and calories to reduce intake. Finally, open your legs and increase your consumption. Perform aerobic exercise for more than 30 minutes a day to burn calories and prevent obesity. With the development of science, the source of infectious diseases is no longer the common virus, fungus, in the past some seemingly only with personal habits related to the disease also has a “contagious” nature. But in fact, we do not have to panic too much, with the in-depth study of microorganisms, coupled with their own habits of health, some similar to obesity, diabetes and other traditional non-communicable diseases will still be away from you. And for those who already belong to the obese or suffer from diabetes people, sugar fat patients should be treated as soon as possible, such as weight loss surgery that has begun to be known to many people in recent years. At present, weight reduction metabolic surgery has become a more classic surgical method for treating obesity and type 2 diabetes, and has been included in the treatment guidelines of countries at home and abroad. What’s more, bariatric metabolic surgery is suitable for the treatment of obese patients and the complications related to obesity (hypertension, sleep apnea syndrome, polycystic ovary syndrome, etc.)! Simply put, weight loss metabolic surgery is effective in treating the complications caused by obesity in addition to effectively losing up to 70% of the body’s excess weight.
