An AFI <5 cm is considered oligohydramnios and an AFI >25 cm is considered polyhydramnios. Randomized control trials have shown that use of AFI can cause an increased number of false positive diagnosis of oligohydramnios and recommend using the measurement of a single deepest pocket (SDP) of amniotic fluid to diagnose oligohydramnios instead.

Diabetes is a condition that causes blood sugar levels to become higher than normal. This is due to problems with how the body makes or uses insulin, the hormone that manages blood sugar (glucose ...
Post-maturity is more likely to happen when a mother has had a post-term pregnancy before. After one post-term pregnancy, the risk of a second post-term birth increases by 2 to 3 times. [8] Other, minor risk factors include an older or obese mother, a white mother, male baby, or a family history of post-maturity. [9]
Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to type 1 diabetes and gestational diabetes. [1] In type 1 diabetes, there is a lower total level of insulin to control blood glucose, due to an autoimmune -induced loss of insulin-producing beta cells in the pancreas .
Oligohydramnios is the cause of Potter sequence, but there are many things that can lead to oligohydramnios. It can be caused by renal diseases such as bilateral renal agenesis (BRA), atresia of the ureter or urethra causing obstruction of the urinary tract, polycystic or multicystic kidney diseases, renal hypoplasia , amniotic rupture ...
A deformed pelvis is a risk factor for obstructed labour: Specialty: Obstetrics: Complications: Perinatal asphyxia, uterine rupture, post-partum bleeding, postpartum infection [1] Causes: Large or abnormally positioned baby, small pelvis, problems with the birth canal [2] Risk factors: Shoulder dystocia, malnutrition, vitamin D deficiency [3 ...
A large fetus can be one cause of CPD. A large fetus can be caused by gestational diabetes, postterm pregnancy, genetic factors, and multiparity. [citation needed] The shape of the pelvis can also be a cause of CPD. The pelvis may be too small, or the shape of the pelvis may be malformed. [2]
Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. [5] [6] Many birth defects are believed to involve multiple factors. [6] Birth defects may be visible at birth or diagnosed by screening tests. [10]
