Hypoparathyroidism
Treatment — Houston, TX
Hypoparathyroidism is a rare endocrine disorder where the parathyroid glands produce too little PTH, leading to dangerously low calcium levels. Our endocrinologists in Houston specialize in diagnosing and managing this complex condition with precision and long-term care.
Quick Facts
What Is Hypoparathyroidism?
Hypoparathyroidism occurs when the parathyroid glands — four small glands behind the thyroid — fail to produce adequate parathyroid hormone (PTH). Without enough PTH, calcium levels in the blood fall too low (hypocalcemia) and phosphate levels rise.
The most common cause is accidental damage to or removal of the parathyroid glands during thyroid or neck surgery. Other causes include autoimmune destruction, genetic conditions, magnesium deficiency, and radiation to the neck.
This is a condition that requires an endocrinologist's expertise for accurate diagnosis, careful calcium management, and long-term follow-up to prevent serious complications such as seizures, cardiac arrhythmias, and cataracts.

How We Manage Hypoparathyroidism
Comprehensive Calcium & PTH Evaluation
We measure serum calcium (total and ionized), phosphate, magnesium, PTH, Vitamin D (25-OH and 1,25-OH), and 24-hour urine calcium to fully characterize your calcium metabolism and establish a treatment baseline.
Calcium & Active Vitamin D Replacement
The cornerstone of treatment is oral calcium supplementation combined with active Vitamin D (calcitriol or alfacalcidol), which bypasses the PTH-dependent step in Vitamin D activation. Dosing is carefully titrated to maintain calcium in the low-normal range while minimizing urinary calcium excretion and kidney stone risk.
PTH Replacement Therapy (When Indicated)
For patients with difficult-to-control hypoparathyroidism or significant complications, we evaluate eligibility for PTH replacement therapy (recombinant PTH), which more closely mimics normal physiology than conventional treatment alone.
Long-Term Monitoring & Complication Prevention
We monitor kidney function, urine calcium, and kidney imaging periodically to detect early nephrocalcinosis. We also screen for cataracts and brain calcium deposits (basal ganglia calcifications) that can develop with long-standing disease.

Hypoparathyroidism FAQ
Is hypoparathyroidism permanent?
Post-surgical hypoparathyroidism can sometimes be transient — especially if the parathyroid glands were temporarily damaged rather than removed. Recovery may occur over weeks to months. Permanent hypoparathyroidism requires lifelong treatment. Your endocrinologist will monitor PTH and calcium levels to determine whether recovery is occurring.
Why is careful dosing important?
Too little calcium supplementation causes hypocalcemia symptoms (cramping, tetany, cardiac risk). Too much causes hypercalciuria (excess calcium in urine), which raises kidney stone and kidney damage risk. Finding the right dose is a careful balancing act that requires regular lab monitoring and endocrinology expertise.
Can I take regular Vitamin D instead of calcitriol?
No. Standard Vitamin D (cholecalciferol or ergocalciferol) requires PTH for its final activation step in the kidney. Since patients with hypoparathyroidism lack PTH, they need active Vitamin D (calcitriol or alfacalcidol), which is already in its active form and does not require PTH for activation.
Do I need to see an endocrinologist if my primary care is managing my calcium?
Hypoparathyroidism is a complex endocrine condition with significant long-term complication risk. Endocrinology co-management ensures optimal calcium titration, appropriate monitoring for kidney and eye complications, and access to newer therapies such as PTH replacement when conventional treatment is inadequate.
