Obesity is a disease that endangers physical and mental health. So do you know why obesity can cause death in daily life? Recently, the International Obesity Conference announced that the number of people who died of obesity worldwide has exceeded the number of people who died of starvation worldwide in the same period. And China’s obese population is about 90 million people, accounting for 8% of the total population, 17% of the urban population is obese; Beijing’s obese population accounts for more than 30% of the total population of the city. In this regard, the international and domestic medical community believes that obesity is the main risk factor for the development of non-communicable diseases, is a potential killer, it will quietly let obese people appear sugar and lipid metabolism disorders, cardiovascular disease and fatty liver disease, etc., until death. Obesity first endangers the human whistle. It is known that when a person’s weight increases, the lungs must deliver more oxygen to supply the body’s needs, however, the lungs will not be correspondingly larger because of the person’s weight increase. In addition, the fat in the lower abdomen can also limit the whistling activity of the lungs. The next is the risk of blood pressure. High blood pressure is easy to occur in obese people, if not given timely correction, may lead to stroke, kidney and heart and other organs of different degrees of damage. Again, it is endangering the heart. The heavier a person’s body, the greater the load on the heart, so obese people have a higher chance of heart disease than the average person. When fat deposits in the heart muscle or under the heart membrane, it will form fat heart and make heart function disorder. There is a threat to the blood vessels. Excessive fat accumulation in the arterial walls, will make the blood vessels become smaller, and even cause blood vessel rupture, and then lead to stroke or heart attack. In addition, obesity will also endanger liver function. The liver is one of the most important organs of the human body, long-term alcohol abuse and diabetes, obese people can cause fatty liver, and then cause liver cell necrosis, leading to cirrhosis. Other will also endanger the pancreatic islets. Diabetes is almost always the patent of obese people, research points out that 70%-85% of people will improve the disease once they lose weight. Dangerous bones: obese people’s bones can not bear the weight, often cause joint swelling and inflammation. Dangerous offspring: obese pregnant women, easy to cause labor difficulties or prolong the birth time, affecting the health of the fetus. Severe overweight people, in addition to the difficulty of pregnancy, pregnant women and fetal mortality is also higher. What causes people to be obese?
