Thyroid hormones are a result of the function of the thyroid gland—which is an endocrine gland in the form of a butterfly found in the lower front of the neck. The two thyroid hormones—triiodothyronine and thyroxine—are also known as T3 and T4. T4 is turned into the active T3 in cells, and it reaches the body organs through the bloodstream.
Its main function is to regulate metabolism and provide energy, but it also has a significant influence on the entire body, as it helps the organs to function optimally.
The most common issue linked to the thyroid is hypothyroidism—which is the state of underactive thyroid, that is the gland does not produce sufficient hormones to regulate the necessary body functions.
It can be a result of numerous internal and external factors, such as Hashimoto’s disease, which is an autoimmune condition in which the thyroid is attacked by the immune system itself.
Hypothyroidism can be manifested by numerous different symptoms, including dry skin, brittle nails, fatigue, hair loss, weight gain, body temperature irregularities, feeling cold, poor reflexes, depression, brain fog, mood swings etc.
However, as these symptoms can also indicate other diseases or ailments as well, doctors mat often prescribe some medications that are not adequate, and do not even consider the thyroid imbalance as a potential cause.
Mary Shomon, a thyroid expert and author of numerous books on the theme, states: “People are going in with high cholesterol or depression and are getting handed cholesterol meds and antidepressants. And no one’s ever checking to see if the thyroid is at the root of the problem.”
