Epigenetics refers to the study of how one’s own behavior and environment can affect the way in which the genes work. Unlike changes that occur directly in the genes, epigenetic changes can be reversed and do not affect the DNA sequence; however, they can change the way in which the body reads the DNA sequence. For example, when one encounters two identical twins, their appearance shows some differences, even though they start out looking the same. As the two twins age, the impact of environmental and behavioral factors becomes more prominent, contributing to the changes and differences between the two twins. Therefore, epigenetics could be used as a critical framework for understanding one’s propensity to develop a particular health condition. When it comes to the considerations of epigenetics in terms of a disease for which an individual is at high risk, it is necessary to consider family history as well as environmental factors that add to the development of the adverse health condition. Considering all factors, the most highly likely disease to develop in the future is type 2 diabetes. Type 2 diabetes refers to an impairment in the way in which the body regulates and uses sugar as fuel (Rosen et al., 2018). It is a chronic condition that can be managed with medication and lifestyle changes but cannot be cured completely with no traces of the condition left behind. This conclusion was made based on several factors concerning family history and environmental and behavioral factors. Specifically, both the parent and the sibling had type 2 diabetes, diagnosed as adults. In adulthood, type 2 diabetes is likely to develop as a result of behavioral and environmental factors, such as increased blood pressure, elevated levels of fat in the blood, a sedentary lifestyle, high alcohol intake, obesity and overweight, and others (Rosen et al., 2018). Therefore, since there are direct DNA connections between a parent and a sibling, both of whom developed diabetes as adults, it is essential to consider such information as highly relevant. Other potential diseases included breast cancer, glaucoma, and thyroid disorder, which were identified in other relatives, for which the risk factors are lower. Epigenetics suggests that even in the case of genetic risk factors, there is a possibility to either increase or reduce the chances of developing a disease with the help of environmental and behavioral improvements. Besides, researchers have been focusing on a new research agenda, emphasizing the interactions between health and environmental and social factors. Therefore, social determinants of health represent a considerable part of epigenetics as it seeks to explain any non-medical factors that directly influence health, such as values, attitudes, knowledge, and behaviors (Notterman & Mitchell, 2016). Besides, across an individual’s lifespan, health can be significantly affected by social disadvantages. The study of epigenetics has considered the control of both disease and homeostasis. Considering that the risk of diabetes and its complications is associated with environmental and inherited factors, it is not surprising that research in this area is extensive (Rosen et al., 2018). In addition, Rosen et al. (2018) stated that there are several areas of epigenetic regulation, such as direct methylation of adenine or cytosine residues, covalent
