What Does Excessive Amniotic Fluid Mean
Diabetes?: Most of the time we don't know what causes polyhydramnios. It is associated with maternal diabetes and can result from trouble with the fetal kidneys or swallowing ability. In and of itself, it isn't harmful, though it can result in cord prolapse if the water breaks through an open cervix. Ask your doctor. ...Read moreSee 1 more doctor answer
Polyhydramnios: Excess fluid is associated with preterm labor, preterm delivery, and increased incidence of breech presentation. However, most cases still end well. The more important question is, what is causing the increased fluid? The cause of the polyhydramnios is the most important issue. Your doctor will know what testing needs to be performed. The findings will determine how your pregnancy is managed. ...Read more
Yes: Excess amniotic fluid can be associated with diabetes, infection, and birth defects that prevent the fetus from swallowing. It can also be associated with an increased risk of stillbirth. Once the causes above have been eliminated, testing of the fetus' wellbeing should be done until delivery. ...Read moreSee 2 more doctor answers
Polyhydramnios: Your amniotic fluid level is a bit high. I would expect that your doctor would be rechecking this at least weekly and if not already done you should be seen by a perinatologist. ...Read more
What does it mean to have normal range of amniotic fluid index, but at the upper limit of 22cm (33 weeks). What causes this?
Worth following: The upper limit of normal is still normal, however it is worth following up to make sure in a few weeks the fluid volume has not increased. In at least 1/3 of cases we cannot figure out what causes the fluid volume to be high. It can also be caused by gestational diabetes. Rarely a fetal abnormality that reduces the fetal ability to swallow can cause increased amniotic fluid. ...Read more
Ultrasound at 40weeks today showed AFI 28cm. Excess amniotic fluid? All scans until now had normal amount. Should I worry? Glucose test was normal.
High: The AFI is a little above high normal. There can be several causes, including human error on how they measured. You say ALL scans, why were they doing more than one scan during you pregnancy. There must have been other concerns going on. But, since all were normal until now, I would suggest this is still a low risk finding. Speak with your OB for final interpretation. ...Read more
I had an amniotic fluid test which showed a high concentration of alpha-fetoprotein. What does this mean?
Could having excess amniotic fluid at 33-35 weeks cause pre- term labour? (levels were 22cm and considered "normal, but at higher range").
Yes: Excess fluid causes distension or additional "stretching " of uterine muscle and may make it more irritable and contract more. 22 cm is not terribly high but still could cause an increase in contractions. You need to be checked to see if this is causing true preterm labor with cervical change or just preterm contractions. ...Read more
No big deal.: Detecting renal problems by fetal ultrasound is very accurate and efficient because it can prevent serious complications postnatally. Fetal renal pyelectasis or even hydronephrosis is nothing to worry about, provided the amniotic fluid is monitored and remains normal. The neonatology team should be notified at birth to institute appropriate follow-up for the newborn; monthly ultrasounds are needed. ...Read moreSee 1 more doctor answer
