THYROID

The thyroid is one of the important endocrine glands in the body. It is a butterfly shaped gland in the neck. It mainly regulates metabolism in the body. It contains follicular and parafollicular cells, which produce hormones such as T3, T4 and calcitonin. The production of the hormones T3 and T4 is regulated by another hormone, TSH (Thyroid Stimulating Hormone) from the master gland, the pituitary. Iodide is required for the production of T3 and T4.

Actions: Free form of thyroid hormones (constitutes 1%) is responsible for all actions, while 99% is found in bound form. Among T3 and T4, free T3 is responsible for physiological actions.

  • Increases Basal metabolic rate: Oxygen consumption
  • Carbohydrate, lipid portion, cholesterol mechanism, growth of brain, bone
  • Increase responsiveness of the heart to circulating catecholamine like norepinephrine (that controls heart rate, stroke volume, and contractility of the heart)
  • Increases body heat

Hyperthyroidism       heat intolerance

The two major thyroid conditions are

  • Hyperthyroidism: excessive production of T3 and T4.
  • Hypothyroidism: decreased production of T3 and T4.

Signs and Symptoms

It depends on the underlying condition.

TFT TEST

Thyroid-stimulating hormone (TSH) is one of the most common thyroid tests. It is a blood test to evaluate the level of thyroid hormone in the body. The thyroid gland is supervised by the pituitary gland, which is present in the brain. If the thyroid gland produces less hormone, the pituitary gland will generate more TSH to ensure normal functioning, and vice versa. If TSH levels are high in the blood, that means that the thyroid gland is secreting less hormone, and if TSH levels are low in the blood, it simply implies that the thyroid gland is secreting hormones in large quantities. This is how thyroid is diagnosed at the basic level. Based on the complexities and condition of the patient, doctors may suggest a few more combinations of tests for a clear understanding.
