Today, America faces what can be considered an “obesity epidemic”. An estimated 69 million americans are considered obese, and obesity is the #2 cause of preventable death in America. Obesity can lead to a number of dangerous conditions and even life threatening conditions. Consequences of obesity include coronary heart disease, type 2 diabetes, different types of cancers, stroke, live disease, sleep apnea, arthritis and more! In addition to health consequences, the epidemic of obesity in america also includes severe economic consequences. In 2002, the estimated health care expenditure for obesity-related issues was $147 billion.
The statistics concerning obesity, childhood obesity, money lost due to obesity etc. are shocking. America is deeply affected by a preventable issue affecting roughly 35% of adult americans and 20% of youth americans. Scientists and doctors have long explored ways to address this issue medically. Until recently, it was believed that the part of the brain controlling appetite is fully developed before birth, and therefore, cannot be altered. As genetics play a big role in weight and appetite control, the ability to alter the appetite control center (the hypothalamus) would be a huge step in “curing” obesity.
However, “research published in theJournal of Neuroscience has identified a population of stem cells capable of generating new appetite-regulating neurons in the brains of young and adult rodents”. This information suggests that altering the appetite regulation system in humans is a possibility.
