Levothyroxine Sodium (T4) is a synthetic form of the thyroid hormone thyroxine. It is commonly prescribed as a medication to treat an underactive thyroid gland (hypothyroidism).
Levothyroxine works by replacing or supplementing the natural thyroid hormone in the body. Thyroxine is responsible for regulating various metabolic processes in the body, including growth, development, and energy production. In hypothyroidism, the thyroid gland does not produce enough thyroxine, leading to symptoms such as fatigue, weight gain, and depression.
By taking levothyroxine, the body receives an adequate supply of thyroxine, which helps restore normal thyroid hormone levels. This helps alleviate the symptoms of hypothyroidism and improves overall metabolism and energy levels.
It is important to note that levothyroxine should be taken exactly as prescribed by a healthcare professional, as the dosage needs to be carefully adjusted based on individual needs and regular monitoring of thyroid hormone levels.
