Amniotic Fluid Index of 19.32 during 31st week scan

Oh dear, I understand why you are worried, but try not to panic too much, an AFI of 19.32 at 31 weeks is on the higher side (polyhydramnios range typically starts around 25, but anything above 18 does get monitored more closely), so your doctor is right to flag it early and adjust your diet now. Cutting rice and sweets is really about managing blood sugar, because high glucose levels can cause the baby to produce more urine, which raises the fluid, so it is not that you can never have anything sweet ever again, but you genuinely need to keep it very controlled, maybe swap to a small piece of fruit instead of cake or sugary drinks. My neighbour went through something similar around 32 weeks and her doctor put her on a strict low-GI diet with repeat scans every two weeks to track whether the fluid level was coming down, which thankfully it did by week 36. The honest truth is that if diet changes do not help, some mums do get referred to a maternal-fetal specialist for closer monitoring, so do not brush off the follow-up appointments even if you are feeling fine. Please do loop back with your own doctor or OB for a personalised plan though, because everyone's situation is a little different and they will know your full picture best.

Hi mum, I also had slightly higher amniotic fluid towards third trimester before and I remember feeling quite worried after the scan too. From what I was told, an AFI of around 19 is usually on the higher side of normal or borderline depending on the clinic range, so it doesn’t automatically mean danger, but it does mean they will monitor you more closely. If your doctor already asked you to cut down sweets and rice, I think it’s mainly to help control blood sugar because that can sometimes affect fluid levels. I wouldn’t say you must avoid everything sweet completely, but just be more strict and moderate, and follow your gynae advice closely since they know your full case best.
