12/31/2023 0 Comments Symptoms of low amniotic fluidWhile sometimes there is a big gush of fluid when your waters break, you may find that all you have is a slow leak. You are most likely to be monitored regularly if you suffer from any of these conditions to ensure your baby's development is on track and that amniotic fluid levels are sufficient. If your placenta does not function efficiently, it can affect your baby's growth. Conditions include high blood pressure, lupus, diabetes and pre-eclampsia. ![]() There are many conditions that may cause your placenta to stop supplying enough nutrients and blood to your baby. There are numerous clinical reasons as to why you may have developed low amniotic fluid levels, but the most common causes are: Less than two centimetres deep is considered low. Measuring the deepest vertical pocket of fluid gives another measurement which can be compared to the norm. These are then compared to normal levels which have been determined for each gestational week. By combining the four measurements they can score you on the amniotic fluid index (AFI). During an ultrasound the sonographer can check your fluid volume by measuring the depth of the pockets of amniotic fluid in four divided sections of the womb. If you have already had a particularly small baby or one with a low birth weight, or you have blood pressure problems, lupus or a specific medical condition, your amniotic levels will be routinely checked. Your midwife should pick this up when she either measures your bump or during an ultrasound. Low amniotic levels may be suspected if your baby seems to be smaller than expected for its gestational age. If there is too much amniotic fluid it is called polyhydramnios. If there is not enough amniotic fluid surrounding the baby, it is known as oligohydramnios. Fluid secreted by the baby's respiratory tract is also a contributing factor. During the second half of pregnancy, the excretion of the baby's urine becomes a major source of the amniotic fluid production. The volume decreases towards term, with an average of about 800ml at 40 weeks. It peaks at 34-36 weeks of gestation with about 1 litre of fluid. At 10 weeks gestation the volume is about 30ml. The volume of fluid increases as your pregnancy progresses. The levels rise and fall as the baby routinely swallows amniotic fluid and then passes it out of their body as urine. The amount of fluid contained in the amniotic sac changes throughout the day. It also works to protect your baby against any infections and it helps with the maturation of your baby's digestive system and lungs. The purpose of the amniotic fluid is to protect your baby against bumps and squashes. This is also known as your waters breaking. When the baby is ready to be born, these membranes break open and out flows the fluid. These membranes ensure your baby is contained within the amniotic fluid throughout your pregnancy. This is the amniotic sac and it consists of two membranes, the amnion and the chorion. Amniotic fluidĭuring pregnancy, the uterus holds a fluid filled sac in which the baby develops. The amount of amniotic fluid alters week by week and can be compared to the norms at any stage of pregnancy. Measured by the amniotic fluid index (AFI), oligohydramnios is diagnosed as having less than the fifth percentile of fluid for your gestational age. This is where there is too much amniotic fluid present in the womb. ![]() The opposite condition is called polyhydramnios. If you are diagnosed with low amniotic fluid, the doctor may conclude that early delivery is the safest treatment.Oligohydramnios is better known as having low amniotic fluid. However, this is generally done to relieve pressure on the umbilical cord during labour or to enhance an ultrasound image. It is possible to increase the amount of amniotic fluid by injecting saline into the amniotic sac in a process called amnioinfusion. The umbilical cord may become squeezed during labour.While it is important to keep in mind that every women is different, oligohydraminos can cause the following complications: The baby is not growing at the correct rate.What are the symptoms of low amniotic fluid? Birth defects such as a kidney or urinary tract problemģ.Placental abruption – when the placenta comes away from the wall.There are a number of reasons why you might be experiencing low amniotic fluid, including: Maximum vertical pocket of less than 2 cm.Amniotic fluid volume of less than 500 ml.Low amniotic fluid, or oligohydramnios as it is medically known as, is defined by the following: What does having low amniotic fluid mean?
