Do I still need to take calcium supplements during the menstrual cycle? If calcium is supplemented, how exactly should it be supplemented? Obstetricians remind “new mothers” that they must take calcium supplements during the menstrual period. For one thing, the direct result of calcium deficiency in the mother is calcium deficiency in the milk, which further leads to congenital calcium deficiency in the newborn baby during the breastfeeding period. The mother’s calcium deficiency will lead to rickets in the baby, affecting tooth eruption, physical growth and neurological development. The second is the need for calcium supplementation after childbirth. According to relevant data, if a woman urinates 1000-1500 ml per day, she will lose about 500 mg of calcium, which shows the rate of calcium loss in women after childbirth. If not supplemented with adequate amounts of calcium will cause back pain, leg and foot cramps, loose teeth, osteoporosis and other such “moon disease”. Therefore, it is best to take a certain amount of calcium tablets orally every day, and it is recommended to drink at least 250 ml of milk every day to replenish the calcium needed in breast milk, and to drink yogurt in moderation to improve the new mother’s appetite. In addition, the mother should also eat more beans or soy products every day, and at the same time, she can also eat some cheese, sea rice, sesame or broccoli according to her taste to ensure that her calcium intake reaches at least 800 mg. In addition, new mothers can also get more sunshine, which will also promote bone density recovery and increase bone hardness.
