What are the side effects of increased secretion of thyroid hormones?
Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body’s metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.
What does over secretion of thyroxine cause?
If your body releases too much thyroxine, you will suffer a condition called thyrotoxicosis. This can cause a goiter, which is a swelling of the neck because of an enlarged thyroid gland.
What is the side effect of thyroxine?
Tell your doctor right away if any of these unlikely but serious effects of high thyroid hormone levels occur: increased sweating, sensitivity to heat, mental/mood changes (such as nervousness, mood swings), tiredness, diarrhea, shaking (tremor), headache, shortness of breath, bone pain, easily broken bones.
Can too much thyroxine cause hyperthyroidism?
The thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3). In most cases of hyperthyroidism, the thyroid gland itself produces too much of these hormones. Hyperthyroidism can also be caused by taking too much thyroid hormone medicine for hypothyroidism. This is called factitious hyperthyroidism.
What does it mean if free thyroxine is high?
High levels of any of these tests (total T4, free T4, or free T4 index) may indicate an overactive thyroid, also known as hyperthyroidism. Low levels of any of these tests (total T4, free T4, or free T4 index) may indicate an underactive thyroid, also known as hypothyroidism.
What are the side effects of too much thyroxine?
What happens if I overdose on Levothyroxine (Synthroid)? Overdose symptoms may include headache, leg cramps, tremors, feeling nervous or irritable, chest pain, shortness of breath, and fast or pounding heartbeats.
What does thyroxine do to the body?
Thyroxine controls how much energy your body uses (the metabolic rate). It’s also involved in digestion, how your heart and muscles work, brain development and bone health. When the thyroid gland does not make enough thyroxine (called hypothyroidism), many of the body’s functions slow down.
What are the effects of thyroxine on the body?
It increases the possibility of childbearing and promotes the secretion of milk by the breasts. Thyroxine also plays an important role in the skin as it increases hydration, secretions of exocrine glands, hair growth. The levels of the hormone thyroxine can be tested through the thyroxine test.
How is thyroxine released from the thyroid gland?
Therefore, when synthesis of thyroid hormone ceases, the physiological effects of deficiency are not observed for several months. About 93 percent of the thyroid hormone released from the thyroid gland is normally thyroxine and only 7 percent is triiodothyronine.
What causes high thyroxine levels in the blood?
For some people, high thyroxine levels are due to the development of a disorder called Graves’ disease, which creates excess T 4. Other causes include viruses, and treatment for hypothyroidism where the patient is taking too high a dose of thyroxine.
What’s the best way to increase thyroxine levels?
Exercise is the most practical and easy way to increase the thyroid levels. Doing exercise will stimulate the production of thyroxine by the thyroid glands. A healthy liver will have a great effect in the release of thyroxine by the thyroid gland.
