This condition occurs when the thyroid gland does not release enough T3 and T4 hormones, which are responsible for bringing enough energy to the majority of the body’s cells in order for them to function.
When there are not enough of these hormones, a person will start to notice how their metabolism slows: they begin to encounter symptoms such as greater sensitivity to the cold, exhaustion, fatigue, low energy, muscle pain, brittle hair and nails, weight gain and even feeling sad or depressed.
Hypothyroidism can be triggered by iodine deficiency; yet this is uncommon, as great progress has been made in iodizing foods throughout the world. Its most frequent causes, as MedlinePlus states, are viral infections, an autoimmune response from the body and the use of certain medications.
In order to detect any irregularities and begin proper treatment, the recommendation is to get regular diagnostic testing both for the thyroid-stimulating hormone (TSH) and the T3 and T4 hormone.
Hypothyroidism affects between 2% and 4% of the worlds’ population.
