Your baby rests inside a fluid-filled sac in the uterus. This is the amniotic sac, and its fluid is known as amniotic fluid. The fluid is important for the safety and health of the foetus growing inside you. At times, however, the quantity of amniotic fluid may not be as expected, which could lead to health issues for the little life growing inside you. In this article, we shall talk about the functions of amniotic fluid, the possible causes of changes in its volume and tips you could use to increase it. Read on to learn more about how to increase and decrease amniotic fluid naturally during pregnancy.

What Does the Amniotic Fluid Do?

The amniotic fluid helps to:

  • Lessen the impact when your baby bumps against the uterine walls
  • Develop the digestive system and lungs of your baby
  • Protect your baby from any infections

If your body has too much or too less of amniotic fluid, it can cause complications during pregnancy ranging from a cracked placenta to preterm labour. Typically, the amniotic fluid index should be 8 – 18 in a normal pregnancy.

How Much Amniotic Fluid Is Needed for Normal Delivery?

If your body has too much or too little amniotic fluid, it can cause complications during pregnancy ranging from a cracked placenta to preterm labour. The amniotic fluid index should typically be 8-18 in a normal pregnancy. During pregnancy, the amniotic sac, which is a fluid-filled sac that surrounds and protects the fetus, gradually fills with amniotic fluid. 

During delivery, it is important to have adequate amniotic fluid to help cushion the baby and facilitate the birth process. However, the amount of amniotic fluid needed for a normal delivery can vary depending on a variety of factors, including the size and position of the baby, the mother’s pelvic shape, and the strength of her contractions.

Generally speaking, a normal range of amniotic fluid during delivery is between 500 and 1000 ml. However, a range of 800-1200 ml of amniotic fluid is also considered normal. If the significantly less amniotic fluid is present during delivery, it could indicate a condition called oligohydramnios, which can increase the risk of complications during delivery, such as umbilical cord compression and fetal distress.

What Are the Causes of Low Amniotic Fluid?

When your amniotic fluid index is less than 5 six, then it’s a low level of amniotic fluid or oligohydramnios. A deficiency of amniotic fluid can affect your child’s hands, feet, lungs, limbs and, rarely, also his face. Low amniotic fluid can happen if:

  • Your water breaks.
  • You have chronic high blood pressure or diabetes.
  • Your placenta moves away from the inner wall of the uterus before delivery, depriving your baby of nutrients and oxygen.
  • You take medications like angiotensin-converting enzyme (ACE) inhibitors.
  • Your baby has problems with the kidneys or urinary tract.
  • Fetal growth is poor.

Risks of Having Low Amniotic Fluid

Low amniotic fluid, or oligohydramnios, is a condition with insufficient amniotic fluid in the amniotic sac. This can occur for various reasons and can increase the risk of several complications during pregnancy and delivery. Here are five risks associated with having low amniotic fluid:

1. Preterm labour – Low amniotic fluid levels may cause premature contractions, leading to preterm labour and delivery.

2. Fetal growth restriction – Amniotic fluid helps to cushion the baby and allows it to move around freely. Too little amniotic fluid may give the baby less space to move and grow, restricting growth.

3. Umbilical cord compression – When there is not enough amniotic fluid, the baby may be at risk of compression of the umbilical cord, leading to decreased oxygen and nutrient supply.

4. Fetal distress – Low amniotic fluid levels can cause the baby to become distressed, leading to fetal distress during labour and delivery.

5. Meconium aspiration – In some cases, when there is low amniotic fluid, the baby may pass meconium (faecal matter) into the amniotic fluid, which can increase the risk of meconium aspiration syndrome, a condition in which the baby inhales the meconium and experiences respiratory distress.

Tips To Increase Amniotic Fluid

Here are some tips to increase the amniotic fluid levels during pregnancy:

1. Drink lots of water throughout the day. It’s one of the easiest ways to increase the amniotic fluid. If you increase the level of water your body has, the level of the amniotic fluid also increases.

2. Foods that have high water content should be on your plate. Some foods that increase amniotic fluid during pregnancy are:

3. Avoid alcohol during pregnancy since it isn’t good for your baby’s health. Alcohol also leads to dehydration and lowers the amniotic fluid level in your body.

4. Avoid herbal supplements that function as diuretics (medicines that make you urinate more frequently). Excessive urination makes you dehydrated. So, it’s essential to always keep yourself hydrated to maintain and increase the amniotic fluid level.

5. Perform light exercises regularly. You should work out every day; even walking helps. Working out regularly during pregnancy helps increase the blood flow to the placenta and the uterus, thus increasing the amniotic fluid level in your body.

Note: You should workout only if your gynaecologist hasn’t prescribed complete bed rest.

Amniotic Fluid During Pregnancy

What Are the Causes of High Amniotic Fluid?

When your amniotic fluid index is in the range of 20 – 24, then it’s termed as a high level of amniotic fluid or polyhydramnios. High levels of amniotic fluid can cause placental abruptionspremature labour, postpartum haemorrhage and caesarean delivery. The causes of polyhydramnios are:

  • Maternal diabetes
  • Birth defect in the baby’s gastrointestinal tract or central nervous system
  • Identical twin pregnancy complication in which one baby receives too much blood and the other too little.
  • Deficiency of red blood cells in the baby
  • Infections to the mother during pregnancy
  • Blood incompatibilities between the mother and baby

What Complications Can High Amniotic Fluid Lead To?

Polyhydramnios can lead to the following pregnancy complications:

  • Placental abruption
  • C-section delivery
  • Premature childbirth
  • Premature rupture of membranes
  • Umbilical cord prolapse
  • Stillbirth

Tips To Decrease Amniotic Fluid

Here are some tips to reduce amniotic fluid during pregnancy:

  1. Sometimes, the amniotic fluid can increase due to a disease. Treatment of the disease will help to lower the level of amniotic fluid.
  2. Amniocentesis is a process used to drain the excess amniotic fluid from your body. This should be the last resort as it can cause preterm labour and delivery.
  3. The doctor may put you on indomethacin. It helps reduce the amniotic fluid level and is generally prescribed 31 weeks before delivery.

When to Consult a Doctor

It is important to consult a doctor if you have concerns about your amniotic fluid levels or experience any symptoms of low amniotic fluid. Some signs of low amniotic fluid include decreased fetal movement, a decrease in the size of your uterus, and abnormal ultrasound.

If you suspect you may have low amniotic fluid or experience any of the risks associated with low amniotic fluid, such as preterm labour, fetal distress, or meconium aspiration, you should contact your healthcare provider immediately. Additionally, if you have any pre-existing medical conditions affecting your amniotic fluid levels, such as gestational diabetes or preeclampsia, you should discuss this with your doctor and receive regular monitoring to ensure that your amniotic fluid levels remain within the normal range.

Overall, if you have any concerns or questions about how to increase and decrease amniotic fluid naturally during pregnancy or the health of your pregnancy, it is important to consult with your doctor or healthcare provider as soon as possible.


1. Does Caffeine Decrease Amniotic Fluid?

There is limited research on the effects of caffeine on amniotic fluid levels. However, some studies suggest that consuming high levels of caffeine during pregnancy may be associated with decreased amniotic fluid levels. It is recommended that pregnant women limit their caffeine intake to less than 200 mg per day to reduce the risk of adverse effects on the pregnancy. This is one food to decrease amniotic fluid during pregnancy.

2. How Can You Check/Determine Amniotic Fluid on Ultrasound?

Amniotic fluid levels can be determined by ultrasound. During the ultrasound, the technician will measure the largest vertical pocket of fluid, the amniotic fluid index (AFI). A normal AFI ranges between 5 and 25 centimetres, depending on the fetus’s gestational age. If the AFI is below the normal range, it may indicate low amniotic fluid levels.

3. Does Walking Help to Reduce Amniotic Fluid?

Walking has not been shown to reduce amniotic fluid levels directly. However, staying active and maintaining good hydration can be helpful during pregnancy and may contribute to overall better health and well-being for both the mother and baby. If you have concerns about your amniotic fluid levels, it is important to consult with your doctor or healthcare provider for personalised recommendations.
