Pregnant women often experience foot cramps, dizziness, or limb weakness. Moreover, such situations often occur at night, and pregnant women cannot get sufficient sleep as a result. Compared to this situation, the second pregnancy is even more severe. The reason why pregnant women experience such situations is actually due to calcium deficiency. So, why does a second pregnancy result in calcium deficiency?
Pregnant women in their second child may experience even more calcium deficiency than their first child, leading to foot cramps, lower back pain, limb weakness, and even loose teeth. The reason for this situation is as follows. Pregnant women need a large amount of calcium during pregnancy to meet the normal development of the fetus. This not only needs to meet one's own metabolism, but also provides the necessary bone mass for fetal development.
At the same time, the concentration of calcium in the blood of pregnant women decreased. During pregnancy, the blood volume in the pregnant woman's body suddenly decreases, and the calcium concentration in the blood also decreases as a result. In order to maintain calcium balance in the blood, the body will automatically break it down from bone regulation, which is also one of the reasons for calcium deficiency in pregnant women.
Also, during pregnancy, the glomerular filtration of pregnant women is enhanced, which allows the body to eliminate more calcium than usual. Because the frequency of urination in pregnant women increases, it invisibly increases the excretion of calcium, which requires more calcium supplementation.
