Hypocalcemia:

Resolve Symptoms. Protect Bone & Nerves.

Hypocalcemia is low blood calcium, often presenting with muscle cramps, tingling in lips/fingers (paresthesias), spasms, or, in severe cases, seizures or cardiac rhythm changes. Because calcium is crucial for nerve conduction, muscle contraction, and bone mineralization, prompt diagnosis matters.

Common Causes

Hypoparathyroidism (post-thyroid/parathyroid surgery, autoimmune)

Severe vitamin D deficiency or malabsorption (celiac, IBD, GI surgery)

Chronic kidney disease (reduced vitamin D activation, phosphate retention)

Acute pancreatitis, tumor lysis, hungry bone after parathyroidectomy

Hypomagnesemia (impairs PTH release/action)

Certain medications (loop diuretics, bisphosphonates shortly after infusion, chemotherapy)

Evaluation

Total & ionized calcium, albumin (to correct total Ca), phosphorus, magnesium

PTH level to distinguish PTH deficiency vs. resistance

25-OH vitamin D (and 1,25-OH₂ in select cases), renal panel

ECG if symptomatic; consider 24-hour urine calcium once stable if recurrent

Management (Personalized to Cause & Severity)

Urgent care (symptomatic/severe): IV calcium gluconate, magnesium correction, cardiac monitoring

Vitamin D deficiency: Repletion to target; address malabsorption and diet

Hypoparathyroidism: Oral calcium + active vitamin D (calcitriol) ± thiazide for hypercalciuria; consider PTH replacement in selected cases

CKD-related: Phosphate control, activated vitamin D analogs under nephrology-endocrine co-management

Medication review: Adjust culprits where possible

Bone Context

Persistent hypocalcemia and low PTH impair mineralization, increasing fracture risk and symptoms such as muscle spasm. We pair biochemical correction with bone-safe strength training, fall prevention, and monitoring.
