thalamus in regu-
lating hormones The hypothalamus is a small but vital region located just above the brainstem.
It plays a central role in regulating many physiological processes and is often
considered a key control center for homeostasis. Through its connection to the
pituitary gland (hypophysis) via the hypothalamo-hypophyseal portal system, the
hypothalamus produces releasing hormones that stimulate or inhibit the secretion
of hormones from the pituitary gland, which, in turn, regulate the activity of other
endocrine glands throughout the body.
The hypothalamus also plays a crucial role in regulating body autonomic functions
(heart rate, blood pressure, temperature, and respirations), hunger and thirst,
emotional responses, and circadian rhythms.
2. Pathophysiology Hypothyroidism is characterized by an underactive thyroid gland that synthesizes
of insufficient amounts of thyroid hormones.

3. Primary Hypothy- Dysfunction is in the thyroid gland, resulting in...
roidism - decreased production of thyroid hormones thyroxine (T4) and triiodothyronine
(T3).
- The pituitary and hypothalamus function correctly, causing increased thy-
roid-stimulating hormone (TSH) and/or thyroid-releasing hormone (TRH).
Causes: thyroidectomy, radiation therapy to the neck, certain medications, or

endemic iodine deficiency (rare).
Hashimoto's thyroiditis is the most common type of primary hypothyroidism. In
this condition, the body's immune system attacks and damages the thyroid gland,
reducing thyroid hormone production.
4. Secondary dysfunction of the pituitary gland or hypothalamus, responsible for producing
Hypothyroidism thyroid-stimulating hormone (TSH) and thyrotropin-releasing hormone (TRH).
(also called
central) This condition may arise due to tumors or dysfunction affecting the pituitary or
hypothalamus.
Dysfunction is in the pituitary gland or hypothalamus, leading to a decreased
stimulation of the thyroid gland and subsequent reduction in thyroid hormone
production.
5. Congenital Hy- Congenital hypothyroidism is present at birth and may result from a variety of
pothyroidism factors, including
genetic abnormalities, defects in thyroid development, or maternal iodine defi-
ciency during pregnancy.
Infants with congenital hypothyroidism may have low levels of thyroid hormones
needed for growth and brain development. Many countries require testing of
newborns to identify and treat congenital hypothyroidism early.
