Obesity plus relapse of pneumonia? The bigger the belly, the smaller the brain?
"Fafu" not only hinders beauty, but also affects brain capacity

"No weight loss in May, sadness in June" may not just be a statement for the pursuit of a good figure. Recently, some studies have shown that obesity is more likely to increase the condition of patients with coronary pneumonia; moreover, there are studies showing that obesity is related to brain volume. People with obesity and a high waist-hip ratio have less gray matter.
Cause excessive immune response
"In the study of New Coronary Pneumonia, some researchers found that obese patients are more severe." Ma Xianghua, director of the Department of Nutrition and Deputy Director of the Endocrine and Metabolism Center of Jiangsu Provincial People's Hospital (First Affiliated Hospital of Nanjing Medical University) said.
According to reports, professors from the University of Edinburgh, the University of Liverpool and the Imperial College of Technology led the study of nearly 17,000 patients with new coronary pneumonia admitted to 166 hospitals in the UK from February 6 to April 18 and found that obese people died more than others The rate is high because their lung function is weakened, and the fat tissue around the subcutaneous and internal organs may have more inflammation, which may cause the "cytokine storm" to intensify. In addition, according to a study initiated by scientists of the British National Medical Service System, almost 75% of critically ill patients with new coronary pneumonia are overweight, and obesity increases the risk of death by nearly 40%. The first problem faced by obese people is excessive immune response, also known as cytokine storm. The severe complications caused by this have led to it becoming an important cause of death.
Obese people have smaller brain volumes
In addition to helping the new coronary pneumonia, the dangers of obesity are "innumerable." Ma Xianghua said that obesity is the basis of many chronic diseases, which can induce high uric acid, hypertension, coronary heart disease, stroke, fatty liver, tumors and so on.
According to "Healthy China Action (2019-2030)", compared with 2002, China's adult obesity rate increased by 67.6% in 2012.
The physical changes caused by obesity are sometimes even "unexpected" by the brain. A study by Loughborough University in the United Kingdom showed that people with obesity and a high waist-to-hip ratio had slightly lower average brain capacity.
In this study, the researchers analyzed information from more than 9,600 people in the UK. Participants measured their body mass index and waist-to-hip ratio and determined their brain volume. It was found that people with high body mass index and high waist-to-hip ratio had the lowest brain capacity.
Specifically, those with a high body mass index and high waist-hip ratio have an average brain gray matter volume of 786 cubic centimeters; and those with a high body mass index but low waist-hip ratio are 793 cubic centimeters; those with a healthy weight, The average brain gray matter volume is 798 cubic centimeters.
"The human brain is mainly composed of gray matter, white matter, and cerebrospinal fluid. Gray matter and white matter are important components of the central nervous system, and gray matter in different brain regions determines different cognitive functions." Brain function of Nanjing Brain Hospital Chen Jiu, director of the research department, said that the atrophy of gray matter in the brain is related to a series of diseases. For example, atrophy of the hippocampus composed of gray matter will cause a decrease in memory; atrophy of the amygdala in the brain area will cause depression; It will cause motor dysfunction and unstable walking.
"However, the study only found that there is a correlation between obesity and lower brain volume, and it cannot yet prove the causal relationship between the two." Chen Jiu said.
What kind of "grievance" is there between obesity and brain atrophy, a research team from Leiden University Medical Center in the Netherlands may reveal the mystery. They published an article in the Journal of Radiology, saying that the higher the body fat ratio, the greater the difference in brain morphology and structure, which in turn leads to smaller brain gray matter volume.
After bariatric surgery, you can't eat Hess
Many obese people want to lose weight and stay healthy. But what if you can't keep your mouth shut and your legs open?
"Sleeve gastrectomy and gastric bypass surgery are currently the most commonly used weight loss and metabolic surgery." Liang Hui, director of the Department of Weight Loss and Metabolism Surgery of Jiangsu Provincial People's Hospital, said sleeve gastrectomy removed about 80% of the stomach, especially secretion The part of hunger hormone, so that satiety will come faster. Gastric bypass surgery is a surgery that changes the structure of the intestine and closes most of the stomach's function. It reduces the area of the stomach and allows food to pass through the duodenum, controlling part of the intestine not to absorb nutrients, so as to achieve weight loss.
Whether a person is obese or needs weight loss and metabolic surgery can be judged by body mass index, which is the weight (kg) divided by the square of height. Liang Hui said that if the body mass index is greater than or equal to 28, it is obesity. If the index is 27.5, surgery can be considered. Especially for patients with metabolic diseases whose index is above 32.5, surgery is recommended.
Ma Xianghua said that performing an operation does not mean once and for all. Even if some people have an operation, if they still cannot change their unhealthy lifestyle, their body will still rebound.
For those who want to lose weight, how to discipline themselves? Ma Xianghua suggested that in terms of diet control, the calories of the staple food supplemented every day should be controlled between 1500 and 1800 calories, which is equivalent to the amount of two or two rice and two or two meat dishes. The maximum daily intake of fruits is about 200 grams, and the daily intake of vegetables is 500 Grams, drinking water 1500-2500 ml. In terms of exercise volume, you can go for an hour a day, while strengthening muscle exercise and improving metabolic rate.
