hypothyroidism
Biology
(noun)
the disease state caused by insufficient production of thyroid hormone by the thyroid gland
Chemistry
(noun)
The disease state caused by insufficient production of thyroid hormones by the thyroid gland.
Examples of hypothyroidism in the following topics:
-
Thyroid Gland Disorders
- Hypothyroidism is the underproduction of the thyroid hormones T3 and T4.
- Hypothyroidism is treated with hormone replacement therapy, such as levothyroxine, which is typically required for the rest of the patient's life.
- But when the hypothyroidism is caused by iodine insufficiency, the thyroid is unable to produce T3 and T4.
- At the beginning, the gland may be overactive, and then become underactive as the gland is damaged, which results in too little thyroid hormone production or hypothyroidism.
- Differentiate among the types of thyroid gland disorders: hyperthyroidism, hypothyroidism, and thyroid nodules
-
Halogen Uses
- Without iodine, thyroid hormones cannot be produced, which leads to a condition called hypothyroidism.
- Children with hypothyroidism may develop mental retardation.
- In women, hypothyroidism can lead to infertility, miscarriages, and breast and ovarian cancer.
-
Development of the Endocrine System
- If there is an insufficient amount of thyroxine, a condition referred to as hypothyroidism results.
- Symptoms of hypothyroidism stem from the fact that there is a reduction in the rate of oxidative energy-releasing reactions within the body cells.
- Hypothyroidism in children, a condition known as cretinism, can result in mental retardation, dwarfism, and permanent sexual immaturity.
-
Pituitary Gland Disorders
- Thyroid-stimulating hormone (TSH) deficiency leads to hypothyroidism (lack of production of thyroxine (T4) and triiodothyronine (T3) in the thyroid).
- In children, hypothyroidism leads to delayed growth and in extreme inborn forms to a syndrome called cretinism.
-
Hormonal Regulation of Metabolism
- Hypothyroidism, underproduction of the thyroid hormones, can cause a low metabolic rate leading to weight gain, sensitivity to cold, and reduced mental activity, among other symptoms.
- In children, hypothyroidism can cause cretinism, which can lead to mental retardation and growth defects.
-
Action of Thyroid Hormones
- One suffering from hyperthyroidism (an overactive thyroid) will experience a fever; conversely, one suffering from hypothyroidism (a less active thyroid) will suffer from a decrease in body temperature.
-
Hypertension
- Hypertension can also be caused by endocrine conditions, such as Cushing's syndrome, hyperthyroidism, hypothyroidism and acromegaly.
-
Carpal Tunnel Syndrome
- Some common conditions that can lead to CTS include obesity, oral contraceptives, hypothyroidism, arthritis, diabetes, and trauma.
-
Breathing Patterns
- Often a symptom of hypertension, heart arryhmias, or slow metabolic rate from hypothyroidism.
-
Formation, Storage, and Release of Thyroid Hormones
- Fetal self-sufficiency of thyroid hormones protects it against, for example, brain developmental abnormalities caused by maternal hypothyroidism.
