When there is too little amniotic fluid, it can potentially cause preterm labor. Insufficient amniotic fluid can lead to fetal hypoxia and asphyxia within the uterine cavity, and frequent fetal movements may induce uterine contractions leading to preterm labor. If reduced amniotic fluid is detected during an examination, it is important to promptly identify the cause and actively pursue treatment. Initially, drinking more water can help improve the condition, and water can also be directly injected into the amniotic cavity to improve the situation. If an examination reveals frequent fetal movements or a reduced fetal heart rate, indicating hypoxia, prompt intervention is needed, and if necessary, pregnancy termination may be considered.
