Hypothyroidism is a common endocrine disorder where in the thyroid does not make enough thyroid hormone.
Subclinical/mild hypothyroidism refers to the state of slightly increased serum TSH with normal serum FT4 in patients who are usually asymptomatic.
Most common cause of primary hypothyroidism is autoimmune thyroiditis or Hashimoto's disease.
Levothyroxine is the first-line agent for treatment of hypothyroidism.
