Hypoparathyroidism is an uncommon endocrine deficiency characterised by low serum calcium, absent or inappropriately low parathyroid hormone and normal or high serum phosphorus levels. Parathyroid hormone is essential for calcium homoeostasis. Pregnancy and lactation are known for increased calcium requirement. They cause calcium stress as well as alter its metabolism. Hence, many abnormalities are expected in hypoparathyroidism during pregnancy and lactation. We report a case of pregnancy in postsurgical hypoparathyroidism, which is rarely encountered in antenatal clinics. We describe our clinical, biochemical and therapeutic experience of pregnancy and lactation in this patient with hypoparathyroidism.
