The thyroid gland secretes hormones that govern several vital bodily functions, including growth and metabolic activity. When the thyroid malfunctions and produces either excess or deficient amounts of hormones, numerous symptoms of ill-health manifest over time. A thyroid problem may relate to hypothyroidism, an underactive thyroid gland, or hyperthyroidism, an overactive thyroid gland.
People with a family history of thyroid or other gland-related medical conditions are at higher risk of developing thyroid problems. Genetics may increase susceptibility to thyroid problems, but this doesn't mean that a genetically predisposed person will develop thyroid conditions; they simply have an increased risk compared to those who do not have those genetic variations related to thyroid. Nonetheless, it is good to know that there is a link between genetics and thyroid disease, and those with a family member who has thyroid issues should be aware of this connection.
