What causes leg pain in late pregnancy?

We all know that women need to provide sufficient nutrition to the fetus after pregnancy to ensure the healthy growth of the fetus. The fetus's demand for nutrition is particularly high in the late pregnancy. Many pregnant women will often experience some different symptoms in the late pregnancy as the fetus grows. Among them, leg pain in the late pregnancy is the most common and common phenomenon. Such symptoms often bring a lot of inconvenience and pain to pregnant women. In order to get effective relief, let's understand what leg pain in the late pregnancy is.

What causes leg pain in late pregnancy?

The reason why pregnant mothers feel pain in the groin is because of excessive separation of the pubic symphysis. The pubic bones are two bones located in the front of the pelvis. There is a gap in the middle instead of being close together. The two bones are connected by ligaments and fibrous cartilage tissue. This area is called the pubic symphysis.

For a non-pregnant woman, the normal distance between the two pubic bones is 4-5mm. During pregnancy, the two hormones, relaxin and progesterone, can help relax the ligaments, and the distance between the two will increase by at least 2-3mm, making the pelvis more elastic, giving the fetus more room to grow, and facilitating the fetus's passage through the pelvis during delivery. Therefore, pubic symphysis separation occurs in almost all pregnant women.

However, some pregnant women may be too sensitive to the above-mentioned hormones, which makes the pubic symphysis area very loose and the distance between the two exceeds 10mm; or because of the size and arrangement of the pelvis, this joint is under more pressure, resulting in excessive separation of the pubic symphysis, and then they feel pain in the groin.

This is an introduction to what causes leg pain in the late pregnancy. After understanding it, we know that this phenomenon is normal. We hope that expectant mothers will not be too anxious and worried. They must maintain a good attitude to welcome the arrival of the baby. In addition, they should eat more light and nutritious foods. At the same time, they should also pay attention to keeping the body warm and supplement calcium in time.
