Hypoparathyroidism
Hypoparathyroidism occurs when the parathyroid glands produce insufficient parathyroid hormone (PTH), leading to abnormally low calcium levels in the blood. It is an uncommon but chronic condition that requires long-term management to keep calcium within a safe range.
Key takeaways
- Neck surgery is a common cause, but autoimmune, genetic and magnesium-related causes also occur.
- Management aims to control symptoms while avoiding high urine calcium, kidney stones and over-treatment.
- Calcium, phosphate, magnesium and kidney function need ongoing monitoring alongside symptoms.
An active-vitamin-D listing cannot define treatment; confirmed cause, calcium pattern, urine calcium and kidney health guide care.
What symptoms can occur?
Low calcium can cause tingling around the mouth or fingertips, cramps, twitching and painful spasms. Chronic disease may also involve fatigue or cognitive symptoms, but these are not specific enough to judge control without blood tests.
How is long-term treatment balanced?
Calcium and active vitamin D such as alfacalcidol may maintain calcium, but excessive treatment can increase urine calcium and harm the kidneys. Specialist care may consider PTH replacement in selected cases. See bone health for related context.
When to seek urgent care
Seek emergency care for a seizure, breathing difficulty, sustained muscle spasm, fainting, confusion or an abnormal heartbeat. New tingling or cramping after neck surgery needs prompt assessment.
