Hypoparathyroidism

Hypoparathyreoidismus · Hypoparatyreóza

What it is

Too little parathyroid hormone — most often after neck surgery — so blood calcium falls and phosphate rises.

Symptoms & signs

  • Tingling around the mouth and in the fingers
  • muscle cramps and spasms (tetany)
  • seizures
  • fatigue, brain fog
  • cataracts and kidney stones in the long run

🚩 Get help if…

  • call 112 / 911 now Seizure, or cramps that lock the hands or throat
  • call 112 / 911 now Fainting or racing heart
  • see a doctor soon Tingling around the mouth or in the fingers
  • see a doctor soon Muscle twitches or cramps after a neck operation

Where it strikes

Medical treatment

  • Calcium, PTH, phosphate, magnesium, vitamin D
  • intravenous calcium for tetany
  • oral calcium and active vitamin D (calcitriol, alfacalcidol) — risk of kidney stones and kidney damage
  • correct low magnesium
  • palopegteriparatide — EMA 2023, FDA 2024; hormone replacement that freed most from calcium and vitamin D pills (PaTHway)
  • thiazide to lower urine calcium

Natural & lifestyle

  • Calcium-rich diet
  • fewer phosphate-rich foods (cola, processed food)
  • drink enough

Emerging & experimental

  • Encaleret for the inherited CASR form
  • eneboparatide
  • parathyroid transplantation

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Magnesium — helps only a true deficiency mixed evidence
  • Algae calcium — simply calcium; no advantage anecdotal / traditional
