What is a thyroid gland? How much do people understand about it? The organ is located at the base of the neck, surrounding the trachea. This seemingly insignificant body part plays a vital role in maintaining optimal development and ensuring the balance of an organism’s central nervous system. In cases where it malfunctions, endocrine diseases may arise. This is reflected in Erica* who is a sufferer of Grave’s disease. This essay will first examine the effects of Erica’s medical condition on her physical and psychological health, and on her lifestyle. Secondly, Erica’s personal perception of the disease and reaction to the diagnosis will be discussed. Next, environmental triggers and any other predictors that may have an impact on aspects of the disease will be addressed. Finally, emphasis will be given to Erica’s expectations for the future. The author’s own predictions will also be included strategically throughout the essay.
