Subclinical hypothyroidism may present itself with mild versions of these hypothyroid symptoms, or often just fatigue or depression. Hypothyroidism often occurs along with insulin resistance, and these two conditions share some similar symptoms.
In some cases, hypothyroidism leads to a goiter, an enlargement of the thyroid sufficient to be externally visible. The gland enlarges to try to compensate for its sluggish production. Goiters can also result from an overactive thyroid, called hyperthyroidism. In this case, the gland enlarges in response to attacks by antibodies, which are triggered by the thyroid’s overproduction.
It’s important to note that without treatment or relief of the underlying causes of hypothyroidism, the symptoms will generally worsen over time, eventually resulting in permanent damage.
In the most extreme cases, such as Hashimoto’s disease, the body forms antibodies to its own thyroid gland, creating permanently low thyroid function.
