Introduction Instances of hyper- and hypothyroidism, as well as other health issues associated with the functioning of the thyroid gland, are common health concerns. Since thyroid hormones themselves play vital role in the regulation of growth processes and energy metabolism, they have a drastic effect on a patient’s well-being when over- or underproduced (Azizi, Mehran, Hosseinpanah, Delshad, & Amouzegar, 2017). Therefore, thyroid disease (TD) has drastic effects on an individual unless managed appropriately. Although TD is traditionally associated with weight gain, the specified factors not the only one and by far not the most important one in enhancing the development of TD. Nevertheless, patients with TD often have to deal with the stigma associated with weight and particularly, the label of laziness that people with superficial knowledge of TD often give them. What Causes Thyroid Disease: Autoimmune Issues Contrary to a popular belief, weight has a comparatively small effect on the development of TD. What launches the process of TD emergence and progression is Hashimoto’s thyroiditis, a condition that leads to the thyroid gland inflammation. The resistance to the thyroid hormone, which is another hereditary disorder, can become the factor for acquiring the identified condition. The resistance to the hormone implies that a patient cannot receive the required amount of thyroid and thus, cannot acquire the necessary hormones for encouraging crucial processes such as growth (Yu & Tan, 2017). The presence of weight issues, in turn, has no tangible effect on the progression of TD (Feldt-Rasmussen et al., 2017). Since weight does not affect the production of the thyroid hormone, obesity and any other weight concerns do not affect the progression of TD in the slightest (Azizi et al., 2017). Thus, the assumptions associated with the cause-and-effect relationships between TD and obesity are false. Particularly, claiming that being overweight leads to the acquisition of TD is erroneous. In addition, problems in the functioning of the pituitary gland and hypothalamus can be seen as the essential factors behind the development of TD. The observed phenomenon can be explained by the control that the pituitary gland and hypothalamus have over the thyroid gland (Yu & Tan, 2017).The disruption in the metabolic process that causes patients to gain weight, in turn, is the direct effect of TD and not the cause thereof. Although the two are of them conflated, assuming that weight gain contributes to the development of TD would be a mistake. Therefore, genetic predisposition toward the development of TD can be seen as the primary factor leading to Td issues, whereas obesity and other weight concerns have no tangible effect on the subject matter, contrary to the popular opinion. Thus, the active promotion of change in the contemporary perception of TD among general audiences is required. Weight and Thyroid Disease Although the presence of weight issues does not cause TD, the latter can lead to a significant rise in a patient’s weight. The rapid weight gain occurs due to the malfunctioning of the thyroid gland and the underproduction of the thyroid hormone (Feldt-Rasmussen et al., 2017). The specified factor contributes to a rise in the anabolic action within one’s body, which causes uncontrollable appetite and the following in
