The thyroid is a small, butterfly-shaped gland located at the base of your neck just below the Adam?s apple. It?s part of an intricate network of glands called the endocrine system. The endocrine system is responsible for coordinating many of your body?s activities. The thyroid gland manufactures hormones that regulate your body?s metabolism.
Several different disorders can arise when your thyroid produces too much hormone (hyperthyroidism) or not enough (hypothyroidism).
Four common disorders of the thyroid are Hashimoto?s disease, Graves? disease, goiter, and thyroid nodules.
The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.
When the hypothalamus is not working properly, it can cause problems in the body that lead to a wide range of rare disorders. Maintaining hypothalamic health is vital because of this.
Hypothalamic dysfunction is a problem with part of the brain called the hypothalamus. The hypothalamus helps control the pituitary gland and regulates many body functions.
The thyroid gland produces two related hormones, thyroxine (T4) and triiodothyronine (T3), which play a critical role in thermogenic and metabolic homeostasis. T4 and T3 are normally synthesized and released in response to a combined hypothalamic pituitary signal mediated by thyroid stimulating hormone (TSH) from the anterior pituitary and thyrotropin releasing hormone (TRH) from the hypothalamus. There is a negative feedback from thyroid hormone concentration, primarily T3, to TSH production, causing total T4, total T3, free T4, and free T3 concentrations to move in opposition to TSH concentration.
Hypothyroidism is a condition in which the thyroid gland is functionally inadequate. Causes of hypothyroidism include autoimmune disorders, such as Hashimoto?s thyroiditis, atrophic thyroiditis, and postpartum thyroiditis; iodine deficiency, the most common cause of hypothyroidism in underdeveloped areas; congenital defects; medications or treatments that can result in hypothyroidism; central hypothyroidism in which the thyroid is not stimulated by the pituitary or hypothalamus; and infiltrative processes that may damage thyroid, pituitary, or hypothalamus. These different causes of hypothyroidism are often interrelated. Usually, the exact cause of the hypothyroidism cannot be definitively differentiated.
Hypothyroidism occurs when your body doesn?t produce enough thyroid hormones. The thyroid is a small, butterfly-shaped gland that sits at the front of your neck. It releases hormones to help your body regulate and use energy.
Your thyroid is responsible for providing energy to nearly every organ in your body. It controls functions like how your heart beats and how your digestive system works. Without the right amount of thyroid hormones, your body?s natural functions begin to slow down.
Also called underactive thyroid, hypothyroidism affects women more frequently than men. It commonly affects people over the age of 60, but can begin at any age. It may be discovered through a routine blood test or after symptoms begin.
If you?ve recently been diagnosed with the condition, it?s important to know that treatment is considered simple, safe, and effective. Most treatments rely on supplementing your low hormone levels with artificial varieties. These hormones will replace what your body isn?t producing on its own and help return your body?s functions to normal.
