Abstract
In pregnant women with unexplained oligohydramnios, this randomized controlled trial aimed to evaluate the effects of n-3 polyunsaturated fatty acid (ω-3 PUFA) supplementation on uterine artery blood flow and amniotic fluid index (AFI). A total of 140 women, aged 20–35 years, with singleton pregnancies and AFI <5 cm at 28-36 weeks of gestation were randomly assigned to receive either ω-3 PUFA (1000 mg daily) or placebo for four weeks. The study was conducted at Sir Ganga Ram Hospital, Lahore. Results demonstrated that the ω-3 PUFA group showed significant improvements in AFI (P = 0.001) and uterine artery Doppler indices, including systolic/diastolic ratio (P = 0.01), resistance index (P = 0.041), and pulsatility index (P = 0.002). These findings suggest that ω-3 supplementation may enhance AFI by improving uteroplacental blood flow. However, further studies are warranted to assess neonatal outcomes and to optimize treatment strategies for unexplained oligohydramnios.
