Symptoms

Patients with
hypoparathyroidism can exhibit a variety symptoms

Hypoparathyroidism (HPT) can lead to a broad spectrum of
clinical manifestations—ranging from mild to life-threatening—
such as laryngospasm, seizures, or heart failure. Clinical
presentation is largely determined by the severity and rate of
development of mineral imbalance, as well as disease duration.1

Signs and symptoms

Most patients present with mild, nonspecific signs and symptoms associated with changes in mineral homeostasis.2

Image of muscles as hypoparathyroidism can affect the neuromuscular system.

Neuromuscular3

  • Fatigue
  • Generalized muscle weakness
  • Muscle cramping (sometimes painful),
    manifested as carpal and/or pedal spasm
  • Neuromuscular irritability resulting in tetany
  • Bronchospasm and wheezing
Image of brain as hypoparathyroidism can manifest with neurologic symptoms.

Neurologic3

  • Paresthesia and numbness, especially
    around the mouth and in the fingers and toes
  • Seizures, spells
  • Basal ganglia and brain calcifications
Image of brain as hypoparathyroidism can manifest with neuropsychiatric symptoms.

Neuropsychiatric3

  • Poor memory and concentration
  • Depression
  • Anxiety
  • Personality disturbances
Image of heart as hypoparathyroidism can affect the cardiovascular system.

Cardiovascular3

  • Congestive heart failure, including cardiomegaly,
    pulmonary congestion, and volume overload
  • Chest pain
  • Arrhythmias
  • Heart block
  • Prolonged QTc interval

Symptoms may occur independently of mineral levels. Patients may be:

Asymptomatic
despite having hypocalcemia and/or hyperphosphatemia3

Symptomatic
despite being in the target serum calcium range4,5

  • Asymptomatic
    despite having hypocalcemia and/or hyperphosphatemia3
  • Symptomatic
    despite being in the target serum calcium range4,5

Due to variability in symptom presentation, frequent monitoring is critical when evaluating patients with hypoparathyroidism.2,3,6

Chronic HPT is associated with comorbidities that can affect several organ systems—including renal, neuropsychiatric, skeletal, cardiovascular, and ophthalmologic systems.3

RECOGNIZING COMPLICATIONS

Patients with inadequately controlled hypoparathyroidism can suffer a high burden of illness.7
