Effects on health
Obesity is a huge scourge since the second part of the nineteenth century. For a long time, we didn't really associated obesity to health problems. It took some times before researchers realized these two things were closely united. They found that obesity was a main factor in various diseases. The most common disease caused by obesity is by far the type 2 diabetes. It has been proved that it is directly a cause of this major disease. Obesity is also a cause in a lot of cancer types as colorectal, pancreatic and kidney cancers. Cardiovascular diseases like congestive heart failure and high blood pressure can be caused by obesity. It is also a cause for numerous respiratory disorders like obstructive sleep apnea and asthma. Other physical problems like low back pain, erectile dysfunction, urinary incontinence and menstrual disorders can be caused by obesity. But there is more than physical disorders. There also are mental disorders as depression, dementia and social stigmatization.
The worst thing in these diseases is that they could be prevented if the sufferer would not have been obese. Studies show that the risk to contract these diseases is enormously increased if the person is obese. Obviously, if you are affected by some of these diseases, your chances to die are multiplied by a lot. If you are an obese female resident of the United States, your chances to die are approximately 2 times higher than a woman respecting the healthy weight. It is even worse if you are a man living in the United States! Your chances to die are 3 times higher than a man respecting the healthy weight. In brief, the life expectancy of an obese is hugely reduced.
This is why our society has to do a lot of efforts to stop the huge scourge that obesity is!
