What happens when thyroxine levels are low?

What happens when thyroxine levels are low?

Low levels of thyroid-producing hormones, such as triiodothyronine (T3) and thyroxine (T4), can change the way the body processes fat. This can cause high cholesterol and atherosclerosis (clogging of the arteries), which can potentially lead to serious heart-related problems, such as angina and a heart attack.

What does Hyposecretion of thyroxine cause?

The enlarged thyroid gland is visible as a swelling in the throat known as goitre. Hence, cretinism and goitre are caused by hyper or hyposecretion of thyroxine.

What are the effects of hypersecretion of thyroxine?

Note: Hyperthyroidism is the result of excess thyroid hormone production, it is caused by an overactive metabolism along with increased speed of all the body’s processes. Symptoms comprise surprising weight loss, rapid or irregular heartbeat, sweating as well as petulance, although the aged often undergo no symptoms.

What disease causes thyroxine deficiency?

If your body makes too little thyroid hormone, it’s called hypothyroidism.

What is Hyposecretion of the thyroid gland?

Expand Section. Hypersecretion is when an excess of one or more hormone is secreted from a gland. Hyposecretion is when the amount of hormones that are released is too low. There are many types of disorders that can result when too much or too little of a hormone is released.

What happens when thyroxine is too high?

Overview. 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. Several treatments are available for hyperthyroidism.

What is hypersecretion and Hyposecretion?

Hypersecretion is when an excess of one or more hormone is secreted from a gland. Hyposecretion is when the amount of hormones that are released is too low. There are many types of disorders that can result when too much or too little of a hormone is released.

What happens when thyroxine hormone is under secreted?

One major sign of under secretion of Thyroxine hormone is that it leads to hypothyroidism which is a condition of decrease in metabolism rate of the body. This state of low Thyroxine hormone production in the body is also known as myxoedema 2. An under secretion of Thyroxine can lead to mental and physical sluggishness 3.

What is thyroxine?

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.

How are thyroid hormones produced?

The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone .

What are the causes of thyroxine deficiency?

Not all thyroxine deficiencies are caused due to an improperly working thyroid gland. Thyroid function is directly linked to the secretion of another hormone made by the pituitary gland. If the pituitary gland is not doing its job, the thyroid may produce less thyroxine as a result.
