For instance, hypoparathyroidism is a condition in which the body doesn’t create enough parathyroid hormone. This can
lead to dramatically lowered calcium levels
, which can trigger tetany. Sometimes kidney failure or problems with the pancreas can interfere with calcium levels in the body.
Why does hypocalcemia cause tetany?
Hypocalcemia causes increased neuromuscular excitability by decreasing the threshold needed for the activation of neurons. As a result, neurons
become unstable and fire spontaneous action potentials
that trigger the involuntary contraction of the muscles, which eventually leads to tetany.
Why does hypoparathyroidism cause muscle twitching?
This makes
blood calcium levels fall (hypocalcaemia)
and blood phosphorus levels rise (hyperphosphataemia), which can cause a wide range of symptoms, including muscle cramps, pain and twitching.
How does hypoparathyroidism cause hypocalcemia?
Hypoparathyroidism is the state of decreased secretion or decreased activity of parathyroid hormone (PTH). This lack of PTH leads
to decreased blood levels of calcium (hypocalcemia)
and increased levels of blood phosphorus (hyperphosphatemia).
Why does low calcium cause hyperexcitability?
Low Ca2+ levels facilitate sodium transport,
as the normal inhibition of sodium movement by Ca2+ is lost
. Thus, low Ca2+ levels result in hyper-excitability of excitable tissues, including cardiac myocytes.
Does tetany leave lasting damage to the body?
Because tetany can be due to a serious condition, failure to seek treatment can result in
serious complications and permanent damage
.
How can we stop tetany?

What are the 4 clinical manifestations of hypoparathyroidism?
Signs and symptoms of hypoparathyroidism can include:
Tingling or burning in your fingertips, toes and lips
.
Muscle aches or cramps in your legs, feet, stomach or face
.
Twitching or spasms of your muscles
, particularly around your mouth, but also in your hands, arms and throat.
When should I worry about muscle twitching?
You should see your doctor if the twitches are
continuous, cause weakness or muscle loss
, affects multiple body parts, begin after a new medication or new medical condition. A muscle twitch (also called a fasciculation) is a fine movement of a small area of your muscle.
Can hypoparathyroidism cause vitamin D deficiency?
Hypoparathyroidism is a state of chronic hypovitaminosis D. Several factors lead to impaired conversion of
25-hydroxyvitamin D (25[OH]D) into its active form
, 1,25-dihydroxyvitamin D (1,25[OH] 2D), in the kidney.
What is the cure for hypoparathyroidism?
Unlike most other hormonal deficits, hypoparathyroidism is not treated with replacement of the missing hormone, parathyroid hormone (PTH). Currently, the standard treatment for hypoparathyroidism consists of
activated vitamin D (calcitriol) and calcium supplements
. Some people may also need magnesium supplementation.
Does hypoparathyroidism go away?
Congenital hypoparathyroidism that occurs during the first few months of life may be temporary (transient) or permanent. In some patients, the cause of hypoparathyroidism is unknown (idiopathic). In some of these cases, hypoparathyroidism may resolve (spontaneously), but
most do not resolve and usually need treatment
.
Can hypoparathyroidism cause weight gain?
Parathyroid disease and hyperparathyroidism are
associated with weight gain
. The worries about gaining weight after parathyroid surgery are understandable but unfounded. It is a myth that parathyroid surgery and removing a parathyroid tumor causes you to gain weight.
What are signs of lack of calcium?
- confusion or memory loss.
- muscle spasms.
- numbness and tingling in the hands, feet, and face.
- depression.
- hallucinations.
- muscle cramps.
- weak and brittle nails.
- easy fracturing of the bones.
What are the causes of low calcium?
- Vitamin D deficiency.
- Chronic renal failure.
- Magnesium deficiency.
- Alcoholism.
- Biphosphonate therapy – drugs used to treat high blood calcium levels or pills used to treat osteoporosis.
- Certain types of leukemia or blood disorders.
What is the effect of low calcium in the body?
An extremely low calcium level may cause
tingling
(often in the lips, tongue, fingers, and feet), muscle aches, spasms of the muscles in the throat (leading to difficulty breathing), stiffening and spasms of muscles (tetany), seizures , and abnormal heart rhythms .
