Patient's question:
Symptoms of Fetal Hypoxia The baby moves more frequently during the day, but becomes less active at night—is this a sign of hypoxia?Doctor's answer:
During the later stages of pregnancy, the frequency of uterine contractions may increase. Sometimes, a tight feeling in the abdomen may be experienced, which could be a sign of contractions. During contractions, the contracting and hardening of the uterus can be distinctly felt. It is also normal to feel fetal movements. However, more frequent fetal movements do not necessarily indicate a lack of oxygen. It is best to conduct a fetal heart monitoring test, as a lack of oxygen can cause the fetal heart rate to exceed 160 beats per minute or fall below 120 beats per minute. The frequency of fetal movements is not fixed. During the 5th to 6th month of pregnancy, fetal movements are most frequent (you are currently in this stage). During active periods, the number of movements can reach hundreds per day. After the 9th month of pregnancy, fetal movements may decrease, and they become even fewer during postterm pregnancy. Throughout the day, fetal movements also vary, generally being more frequent at night and fewer in the morning.
