ABSTRACT
Primary hyperparathyroidism (PHP), more common in women, is a disease associated with high calcium levels. Pregnancy within PHP is a condition of life in terms of both maternal and fetal facts. We’ve reported our patients who came to us with urinary symptoms with hypercalcemia, she was diagnosed as PHP. Surgery was recommended to her but she was not operated. Meantime, patient was pregnant. During her pregnancy, parathyroidectomy was applied at 2 trimester. After parathyroidectomy, preeclampsia was diagnosed. During the follow-up, fetus died of intrauterine death. Her preeclampsia declined, after fetus extraction. By this issue, we wanted to draw attention to complications of PHP throughout pregnancy problems.
