In shorts

  • Maternal calcitonin levels have been reported to be increased in early pregnancy. A rise in calcitonin may protect the maternal skeleton against PTH-induced resorption.
  • Physiological hypercalciuria occurs during pregnancy as a result of increased maternal calcium absorption.
  • The blood urea level falls to 15–20 mg% in pregnancy, Blood uric acid and creatinine level, however, either remain unchanged or fall slightly.
  • Plasma insulin level is increased due to a number of contra insulin factors. These are: estrogen, progesterone, human placental lactogen (hPL), cortisol, prolactin, free fatty acids, leptin, and TNFa.
