The thyroid gland secretes hormones that regulate metabolism.
The thyroid gland produces two primary hormones: thyroxine (T4) and triiodothyronine (T3), which control how the body converts food into energy.
It is shaped like a butterfly.
The thyroid gland is made up of two lobes connected by a narrow tissue bridge, resembling the shape of a butterfly or a bowtie.
It affects almost every cell in the body.
The hormones produced by the thyroid gland have a widespread impact on various organs and tissues, influencing heart rate, body temperature, and even mood.
The pituitary gland regulates thyroid hormone production.
The pituitary gland, located at the base of the brain, senses the hormone levels in the bloodstream and releases thyroid-stimulating hormone (TSH) to stimulate or suppress thyroid hormone production.
Thyroid disorders are prevalent.
Approximately 20 million Americans have some form of thyroid disease, with women being five to eight times more likely to develop these issues compared to men.
Hypothyroidism is a common condition.
Hypothyroidism occurs when the thyroid gland fails to produce enough hormones, leading to symptoms like weight gain, fatigue, and depression.
Hyperthyroidism is another common disorder.
Hyperthyroidism happens when the thyroid gland produces an excess of hormones, resulting in symptoms such as rapid heartbeat, weight loss, and anxiety.
The thyroid requires iodine to function properly.
Iodine, obtained through diet or supplements, is essential for the production of thyroid hormones. Without adequate iodine, thyroid function may be compromised.
Autoimmune diseases can affect the thyroid gland.
Conditions such as Hashimoto’s disease and Graves’ disease are autoimmune disorders in which the body’s immune system mistakenly attacks the thyroid gland, causing it to become underactive or overactive, respectively.
Thyroid nodules are common but usually benign.
Nodules, or abnormal growths, can form on the thyroid gland. Although the majority are benign and cause no harm, some nodules may require further evaluation or treatment.
The thyroid gland plays a role in the development of babies during pregnancy.
Thyroid hormones are essential for fetal brain development, making it crucial for pregnant women to maintain adequate levels of thyroid hormones.
Thyroid issues can affect cholesterol levels.
When the thyroid gland is underactive, it can lead to elevated cholesterol levels, potentially increasing the risk of heart disease.
The thyroid gland can be affected by external factors.
Exposure to radiation, certain medications, and environmental toxins can impact the structure and function of the thyroid gland.
Thyroid hormone levels fluctuate during the day.
Thyroid hormone levels follow a diurnal rhythm, with their highest levels in the late afternoon and lowest levels in the early morning.
Thyroid diseases can run in families.
There is a genetic component to thyroid disorders, and individuals with a family history of thyroid issues may be at higher risk of developing similar conditions.
Thyroid testing involves measuring hormone levels in the blood.
Typically, a healthcare professional will order a blood test to assess thyroid function by measuring levels of TSH, T3, and T4.
Stress can impact thyroid function.
Chronic stress and high levels of cortisol can disrupt the balance of thyroid hormones in the body, leading to potential thyroid dysfunction.
Your diet can support thyroid health.
Eating a balanced diet that includes foods rich in iodine, selenium, and zinc can support optimal thyroid function and overall glandular health.
