Oligo is short for Oligohydramnios which is the technical jargon for low amniotic fluid. Few of us can spell it so we shorten it to Oligo [:)]. The range for normal fluid is 8-25 cm and the drs like to see you around 15 or so. As far as whether or not you will have it again, Catherine, it depends. One of the reasons for oligo is placental complications-it stops or limits production of nutrients so the baby recycles what is there. The baby is not peeing as much to preserve him or herself. Some of the problems for baby is that it can affect the development of vital organs and also the baby can lay on the cord and compress it. PIH and PE are linked to placental problems. The rise in your bp reduces blood flow to baby and that can result in oligo. But, not everyone with PIH or PE have low fluid. Each pregnancy is different, so hopefully you won't have any PIH/PE or oligo this time around. I did not have oligo with my 3rd preg but, I had PE. I had PIH, low blood flow and problems with the placenta with my 4th resulting is oligo. I hovered around 5.8-6.1cm for weeks. The magic number that my dr would have taken the baby was 5 cm or below. Our little Laura was down to 3 cm when they took Camile. Catherine, do you have hypertension when you are not preg? Hope this helps and hope this is an easy preg for you!
