Hypothyroidism Signs and Symptoms

  • Hypothyroidism
    Approximately 11% of Indian adults suffer from hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones to meet the needs of the body. This makes your metabolism slow down. It is also called underactive thyroid. This condition is more prevalent in women than in men, especially among women of child-bearing age.

    Hypothyroidism Treatment
    The goal of treatment is to bring the person back to an euthyroid state (state of having normal thyroid gland function), hence necessitating lifelong thyroid hormone replacement therapy.  Levothyroxine which is a synthetic T4 hormone is the preferred choice of treatment. It is usually prescribed once a day.  L-triiodothyronine which is synthetic T3 is used less frequently due to a shorter half-life.  Combination of the two synthetic hormones is available but with no significant…

    Overview of Hypothyroidism
    What is Hypothyroidism The thyroid is an endocrine gland situated at the base of the neck. It is a vital gland that produces three major hormones : T3 (Triiodothyronine), T4 (Thyroxine) and Calcitonin. These hormones play a major role in the growth, metabolism and development of the human body. (Image captured from https://www.hormones-australia.org.au/the-endocrine-system/thyroid/ ) When there is an insufficient secretion of the T3 and T4 hormones, it leads to a condition termed…
