Hypoparathyroidism is characterized by weakness, muscle cramps; abnormal sensations such as tingling; burning and numbness (paresthesias) of the hands; excessive nervousness; loss of memory, impaired judgment and brain fog; headaches and uncontrollable cramping muscle movements of the wrists and feet. Other symptoms may be spasms of the facial muscles (Chvostek Sign); the contraction of muscles produced by mild compression of nerves (Trousseaus Sign); malformations of the teeth, including enamel and roots of the teeth; and malformed finger nails. In some hypoparathyroid conditions, there may also be pernicious anemia; dry and coarse skin; patchy hair loss (alopecia); thin, scant eyebrows; patches of skin that have lost pigment (vitiligo); and mental depression.
THYROID, PARATHYROID, OR OTHER NECK SURGERY
Hypoparathyroidism may occur after thyroid, parathyroid or other neck surgery where the parathyroid glands are either damaged or removed. When this happens there is either insufficient or no parathyroid hormone available for calcium regulation.
Idiopathic hypoparathyroidism may be inherited or acquired later in life. It can be characterized by the complete absence, fatty replacement or atrophy of, the parathyroid glands. The Familial form of this disorder may be inherited while the Sporadic form usually affects children and is often associated with Addison’s disease, pernicious anemia or premature ovarian failure.
To have an “idiopathic” disease of any kind simply means that the actual cause of the disease cannot be determined.
A rare genetic disorder where the parathyroid glands are actually able to produce parathyroid hormone but the body is unable to detect or respond to it. Pseudo-hypoparathyroidism can affect the parathyroid glands only or it can be part of a syndrome which involves multiple organs.
Rarer yet than pseudohypoparathyroidism, this version of the disorder is where patients express only the Albrights Hereditary Osteodystrophy (“AHO”) phenotype. In this condition there are normal serum calcium levels and no other evidence of hormonal resistance. Treatment is the same as other types of hypoparathyroidism but patients with the AHO may require treatment specific for skeletal disorders.
COMPLEX SYNDROMES IN WHICH HYPOPARATHYROIDISM OCCURS
Hypoparathyroidism can also occur as a component of complex genetic or congenital syndromes in which a variety of tissues or organs are affected. Including DiGeorge syndrome, Hypoparathyroidism–deafness-nephrosis syndrome, and autoimmune polyglandular syndrome type 1.
Symptoms of the following disorders can be similar to those of hypoparathyroidism. Comparisons may be useful for a differential diagnosis.
Hypocalcemia is characterized by abnormally low levels of calcium and high levels of phosphorous in the blood. It is characterized by spasms of the facial muscles, abdominal and muscle cramps, spasms of the foot and wrist (carpopedal), and strange sensations such as tingling and burning or numbness (paresthesias) of the lips, tongue, fingers and feet. In some severe cases, there may be spasms of the larynx and generalized convulsions.
Osteomalacia is a disease that causes softening of the bones due to insufficient levels of calcium. This results in the bones becoming brittle, and easily broken. It is characterized by pains in the limbs, spine and pelvis, and general weakness. It is seen mostly in adult women.
