Obesity is known to have many negative repercussions on health. It affects the entire scope of the body, from head to toe. According to a July 14th, 2014 Medical Daily article, three internal organs most affected by obesity are the heart, colon, and lungs. Obesity and organ damage go hand in hand.
The heart is majorly impacted by obesity. This is because, since the excess fat tissue in the body can only stay alive with the presence of oxygen, the heart needs more blood vessels to bring oxygen-rich blood to the fat tissue. As well, fat can gather inside arteries, which makes them a narrower pathway for the blood that needs to pass through. These factors put extreme stress on the heart, as it has to pump much more forcefully to get blood through. Usually, the stress on the heart leads to poor circulation throughout the body and increased risks of high blood pressure and heart attacks.
The colon is another organ impacted by obesity. While many cancers may have some link to obesity as a cause, researchers have found that obesity does lead to more cases of colon cancer. Among both men and women who are considered overweight or obese, the likelihood of getting colon cancer skyrockets. This is believed to be because of a couple factors; firstly, it is believed that a diet consisting of large amounts of red and processed meats leads to colon polyps, a possible early stage of colon cancer. Secondly, elevated insulin levels in the blood, which occurs with obesity may influence the genesis of colon cancer. Regardless of which cause occurs, the relation between obesity and colon cancer is ever prominent.
Similarly to the way excess fat can damage the heart, the lungs face great risk from obesity. According to Medical Daily, a 2010 study “showed large amounts of adipose tissue diminishes the organs’ overall capacity for air. This in itself poses significant risk for poor ventilation, which can both exacerbate existing respiratory diseases or produce the same side effects even in the absence of those diseases.” Essentially, excess fat limits the amount of oxygen the lungs can absorb and thus the ability to breathe. The impact of obesity on the lungs gives people much more of a risk for developing sleep apnea. It also impacts people’s breathing capability on a daily capacity, which leads to health deterioration over time as oxygen levels in the body become inadequate for maintaining health.-Jamie Clarke
