The thyroid is a butterfly-shaped ENDOCRINE gland located in the neck. It is wrapped around the trachea, just below the thyroid cartilage -the Adam’s apple.
The two major hormones of the thyroid are triiodothyronine, T3 and thyroxine, T4. The numbers 3 and 4 indicate the number of iodine atoms present in a molecule of each hormone. T3 and T4 are collectively referred to as THYROID hormones.
Thyroid hormone secretion is under control of thyroid-stimulating hormone, TSH, from the anterior pituitary. TSH, in turn, is induced by thyrotropin-releasing hormone, TRH, produced by the hypothalamus. The amount of circulating thyroid hormones is regulated by a negative feedback loop: when their levels are too high, they SUPPRESS the production of TSH and TRH, consequently INHIBITING their own production.
Thyroid hormones act to INCREASE the body’s metabolic rate. They stimulate appetite, digestion, breakdown of nutrients and absorption. They also increase oxygen consumption, raise the breathing rate, heart rate and contraction strength. As a result, the body’s HEAT production is INCREASED. Thyroid hormone secretion usually rises in winter months to keep the body warm.
Thyroid hormones are also important for bone growth and fetal brain development.
There are 2 major groups of thyroid problems:
HYPOthyroidism: when the thyroid does NOT produce ENOUGH hormones, resulting in a LOW metabolic rate, combined with SLOW respiratory and cardiovascular activities. Common symptoms include fatigue, weight gain despite poor appetite, cold intolerance, slow heart rate, heavy menstrual bleeding and constipation. Iodine deficiency and Hashimoto's thyroiditis are the most common causes. Hashimoto's thyroiditis is an autoimmune disease in which the thyroid gland is gradually destroyed by the body’s own immune system.
Hypothyroidism, especially when caused by iodine deficiency, may lead to swelling of the thyroid gland, known as GOITER. In an attempt to fix the low levels of thyroid hormones, the pituitary produces MORE TSH to further stimulate the thyroid gland. The thyroid, while UNable to make hormones WITHOUT iodine, responds to TSH by GROWING in size.
Hypothyroidism is managed with thyroxine hormone replacement.
HYPERthyroidism: when the thyroid gland produces TOO MUCH hormones, resulting in a TOO ACTIVE metabolism, together with respiratory and cardiovascular rates that are HIGHER than necessary. Common symptoms include irritability, insomnia, weight loss despite good appetite, heat intolerance, heart racing and diarrhea.
Hyperthyroidism is most commonly caused by Graves' disease, another autoimmune disorder characterized by presence of an antibody, called thyroid stimulating immunoglobulin, TSI. TSI, similar to TSH, stimulates the thyroid gland to produce hormones. Unlike TSH, however, TSI is NOT regulated by negative feedback mechanisms, leading to UNcontrolled production of thyroid hormones. TSI also stimulates the thyroid gland to grow, which MAY lead to formation of a goiter.
Hyperthyroidism may be managed with drugs that suppress thyroid function, radioactive iodine that selectively destroys the thyroid gland, or surgery that removes part of the gland.

I was diagnosed with hyperthyroidism which leads to thyrotoxic heart disease i accumulated most of the symptoms like hair loss for over the years and before i suffer so much from palpitation at 155 hbm i got 4 to 5 times bowel movement it also leads to anxiety sweating
There is nothing God cannot do, take your medications with a dose of biblical declarations and watch God change things. Wishing you a quick recovery.
@@idealsyntheticmarchant8670 Amen
How long it has been to you before you knew it?
It comes from anxiety
Why doesn’t god cure all those devout Christians with terminal diseases? If they truly believe, why are they not cured?
The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream

The thyroid secretes several hormones, collectively called thyroid hormones. The main hormone is thyroxine, also called T4. Thyroid hormones act throughout the body, influencing metabolism, growth and development, and body temperature. During infancy and childhood, adequate thyroid hormone is crucial for brain development.
