1. IntroductionObesity is a label given to people whose body mass index (BMI) is greater than 30. Any individual, male or female, is considered morbidly obese if their BMI is greater than 40 (NHS, 2012 ). Being obese for a period of time can increase the risk of obesity-related diseases, including diabetes, heart disease, and certain types of cancers (colon, bowel, or breast cancer), and even a higher risk stroke (NHS, 2012). The World Health Organization (WHO) (2013) states that obesity can lead to a range of long-term problems on the body and its organs that can lead to preventable diseases and conditions. In particular, obesity can affect the respiratory system (breathing). Weight can put people at higher risk for asthma, sleep apnea and pneumonia. Additionally, obesity can lead to reproductive problems in both men and women, ranging from menstrual disruptions to hormonal imbalances and erectile dysfunction and, in some extreme cases, fertility problems that can lead to potential infertility. There have been suggestions in the past that obesity is a genetic problem, but it has since been established that the human genome, with evidence of single gene mutations in laboratory experiments, has identified a substantial link between genetic risks of obesity. Obesity is the result of a complex pathophysiological process involving numerous factors that may control adipose tissue metabolism (Knott, 2013). In (2007), the Ministry of Health released a report stating that there were fears that by 2050, almost 90% of adults would be categorized as obese.MHADegree.org, (2014).2. Purpose/Hypothesis. The purpose of the experiment was to support the hypothesis that the participant who had a high weight (overweight...... middle of paper ...... me. It is clear that the Obesity can have a negative impact on health and particularly on the respiratory system, this can cause a range of illnesses throughout life, including asthma or its worsening, as well as acute shortness of breath as well as risk. higher rate of pneumonia. Reproduction can also be affected in both men and women. It is suggested that hormonal and menstrual disruptions occur, which could potentially lead to infertility or at the very least. Fertility problems, this could include polycystic ovary syndrome Male reproductive problems could take the form of erectile dysfunction and could interfere with male sperm count morbidity and could further lead to potential fertility problems in the long run. term..
