Healthy thyroid function is essential to feeling energetic and vital. The thyroid is one of the key regulators of global energy production in the body, and thyroid dysfunction can be a source of fatigue or loss of vitality, with many patients not knowing that problems with their thyroid are causing their symptoms.
Hypothyroidism (reduced production of thyroid hormones by the thyroid) slows down metabolism and energy production, resulting in a range of symptoms including fatigue, weight changes, and mood disturbances.
In the UK about 1 in 50 people are diagnosed with hypothyroidism, but undiagnosed hypothyroidism may affect as many as 1 in 10 people. Additionally, the likelihood of developing hypothyroidism is higher for women and increases with age.
This test measures FT3 and FT4, the active thyroid hormones, and TSH, the pituitary hormone that regulates their production. Deviations in these levels can signify an underactive or overactive thyroid, which can impact the body's energy production and metabolic rate.
