Hyperparathyroidism
Hyperparathyroidism occurs when one or more of the four small parathyroid glands in the neck become overactive, producing too much parathyroid hormone (PTH), which raises blood calcium levels and can affect bones, kidneys, and overall wellbeing.
Common symptoms
- often no symptoms at all, found incidentally on a routine blood test
- fatigue and bone or joint pain
- kidney stones
- excessive thirst and urination
- low mood or difficulty concentrating
What we offer
- same-day blood tests to confirm raised calcium and parathyroid hormone levels
- coordinated referral for imaging to locate the overactive gland
- guidance on surgical assessment or monitoring depending on severity
Confirming the diagnosis
Diagnosis uses repeated calcium results interpreted with parathyroid hormone, kidney function, vitamin D, phosphate, medicines and symptoms. Urine calcium and bone-density assessment may help distinguish causes and assess complications.
Monitoring and treatment
Management depends on calcium level, symptoms, age, kidney stones, kidney function and bone health. Some patients are monitored, while others benefit from parathyroid surgery after appropriate specialist localisation and surgical review. Imaging does not establish the diagnosis by itself.
UK-wide video consultations
History and results can usually be reviewed securely by video, while blood and urine tests, DEXA and imaging are arranged locally. Marked confusion, vomiting, dehydration or severe weakness with high calcium requires urgent assessment.
