Pseudohypoparathyroidism is a rare genetic disorder where the body is unable to respond properly to parathyroid hormone (PTH). This hormone is essential for regulating calcium and phosphorus levels in the blood. Although the parathyroid glands produce enough PTH, the body’s tissues do not respond to it, leading to various health issues.
Pathophysiology
- Structure:
- Parathyroid Glands: There are usually four small glands located in the neck that produce PTH.
- Bone and Kidneys: PTH normally stimulates the bones to release calcium and the kidneys to retain calcium and excrete phosphorus.
- Blood Supply:
- The parathyroid glands are supplied by the inferior thyroid artery, which delivers blood and nutrients necessary for hormone production.
- Nerve Supply:
- The nerve supply to the parathyroid glands comes from the cervical sympathetic nerves, which help regulate the function of these glands.
Types of Pseudohypoparathyroidism
- Type 1A: Characterized by resistance to PTH, associated with specific physical features.
- Type 1B: Similar resistance to PTH but without the associated physical features.
- Type 2: Marked by resistance to PTH and other hormones, with different genetic causes and physical features.
Causes of Pseudohypoparathyroidism
- Genetic mutations (GNAS gene)
- Abnormalities in hormone receptors
- Family history of the disorder
- Developmental issues during pregnancy
- Maternal diabetes
- Environmental factors during fetal development
- Low calcium intake during childhood
- Certain syndromes (e.g., Albright’s hereditary osteodystrophy)
- Epigenetic modifications

Diagnostic Tests for Pseudohypoparathyroidism
- Blood tests to measure calcium and phosphorus levels

- Phosphate retention tests
- Parathyroid hormone receptor tests
- 24-hour urine calcium collection
- Bone biopsy (rarely performed)
- Family history assessment
- Physical examination for characteristic features
- Imaging studies to identify other underlying conditions
Non-Pharmacological Treatments for Pseudohypoparathyroidism

- Statins (if cholesterol levels are high)
- Immune-modulating drugs (for autoimmune issues)
- Hormone replacement therapy (if needed)
- Medications for anxiety
- Medications for sleep disturbances
- Topical treatments for skin issues
- Antihypertensives (if blood pressure is high)
Surgical Treatments for Pseudohypoparathyroidism
- Parathyroidectomy (removal of parathyroid glands)
- Thyroidectomy (if the thyroid is affected)
- Bone surgery (to correct deformities)
- Surgery for tumors in the neck area
- Ear surgery (if hearing loss is significant)
- Dental surgeries for severe dental problems
- Repair of fractures or bone abnormalities
- Surgery for other underlying conditions
- Cyst removal (if present)
- Joint surgeries for severe joint issues
Prevention of Pseudohypoparathyroidism

- Managing chronic conditions (like diabetes)
- Promoting a balanced diet from childhood
- Encouraging physical activity from an early age
- Educating families on recognizing symptoms
- Screening for hormone levels in at-risk individuals
When to See a Doctor
- If experiencing unexplained muscle cramps or weakness
- For persistent fatigue or dizziness

- When noticing dental problems or delayed tooth eruption
- If there are symptoms of mood disturbances
- For any unexplained weight gain or loss
- If experiencing abnormal heart rhythms or chest pain
- When having issues with calcium or phosphorus levels
