hypothyroidism

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.
