How to Increase Amniotic Fluid: Foods, Tips and Tricks for Expecting Mothers

A pregnant woman's body starts producing amniotic fluid as early as the 12th day of conception. During the first few months of the pregnancy, this fluid primarily consists of water. In the latter half of the pregnancy, the fluid is majorly made up of the baby’s urine. Amniotic fluid is necessary for your baby to breathe, digest food, regulate the temperature, prevent infection, and cushion from any external injury. Low levels of amniotic fluid, also known as oligohydramnios, can lead to complications like preterm labor, birth defects, and even stillbirth. In this article, we will explore how to increase amniotic fluid.

What is Amniotic Fluid?

During pregnancy, the baby grows inside an amnion or amniotic sac. This sac is filled with amniotic fluid in which the baby floats while growing inside the womb. Amniotic fluid cushions and nourishes the baby, and it is that fluid that leaks out when the “water breaks”.

The chemical composition of amniotic fluid changes as the pregnancy progresses. In the early months, it contains 98% water and minerals. The remaining 2% comprises antibodies, hormones, and nutrients like proteins, carbohydrates, vitamins, etc. However, after 20 weeks, amniotic fluid mainly consists of the baby’s urine.

Apart from protection and nutrition, amniotic fluid also regulates a steady temperature, prevents the umbilical cord from getting squeezed and helps baby's lungs, digestive system, muscles, and bones grow. The amount of amniotic fluid progressively increases until 36 weeks and then decreases, and abnormal amounts of amniotic fluid may cause the healthcare provider to watch the pregnancy more carefully.

What are the Normal Amniotic Fluid Levels?

Amniotic fluid levels can vary throughout pregnancy, but there are general ranges considered to be within the normal range. Around 10 to 20 weeks of gestation, the fluid volume is typically between 25 and 27 milliliters. By 32 to 34 weeks, the volume increases to around 800 to 1,000 milliliters. At full term, which is around 37 to 40 weeks, the volume can range between 800 and 1,200 milliliters.

These ranges are approximate and can vary depending on various factors such as gestational age, maternal health, and the individual pregnancy. It's important to consult with a healthcare provider for an accurate assessment of amniotic fluid levels.

What Contributes to a Low Amniotic Fluid Level?

During your routine prenatal tests and visits, your doctor will check the level of your amniotic fluid. Before 24 weeks of pregnancy, doctors use ultrasound to measure the level. This method is called “maximum vertical pocket”.

However, after 24 weeks, the customary method is the Amniotic Fluid Index (AFI). A normal AFI ranges from 5 to 25 cm. An AFI lesser than 5 cm suggests a low level of amniotic fluid. There could be many reasons for the low level of AFI, including:

• When the placenta isn’t functioning normally or has started to detach itself from the uterine wall, the AFI level falls.
• Congenital anomalies that affect the baby’s kidneys or urinary tract, preventing him/her from making enough urine.
• Maternal complications like high blood pressure, dehydration, diabetes, preeclampsia, and hypoxia.
• Some medications may also affect the level of amniotic fluid.
• Premature rupturing of the membrane, which makes the amniotic sac leak before labour.

How to Increase Amniotic Fluid?

Besides consuming certain food to increase amniotic fluid during pregnancy, there are several home remedies to increase amniotic fluid, such as:

1. Increase your fluid intake

Staying hydrated during pregnancy is crucial to maintain normal amniotic fluid levels and ensure a healthy pregnancy. Drinking lots of water increases the amniotic fluid naturally. It is one of the easiest ways to increase amniotic fluid without any ill effects.

2. Take ample rest

Fatigue and exhaustion can contribute to dehydration and can negatively impact amniotic fluid levels, so taking time to rest is important. Additionally, resting can increase blood flow to the placenta, helping increase amniotic fluid.

3. Consume a healthy diet

Eating a healthy diet is extremely important throughout pregnancy. Have food with high water content like cucumber. Incorporate vegetables like lettuce, spinach, radish, broccoli, and cauliflower, and fruits like strawberries, tomatoes, cantaloupe, and grapefruit.

4. Supplement with L-arginine

L-arginine is an amino acid found in certain foods and supplements that can help increase amniotic fluid levels. Some of the best sources of L-arginine include meat (red meat, chicken, turkey), fish (salmon, haddock), nuts (almonds, cashews, etc.), and dairy products (milk, cheese, and yogurt).

5. Drink coconut water

Drinking coconut water is among the many home remedies to increase the level of amniotic fluid, especially during the third trimester of pregnancy. Studies have shown that coconut water increase amniotic fluid substantially as compared to those taking intravenous fluids with oligohydramnios.

6. Avoid alcohol

In addition to being bad for the baby’s health, drinking alcohol while pregnant also leads to dehydration. Thus, it reduces the level of amniotic fluid. Also, avoid supplements that increase the urge to urinate.

7. Perform light exercises regularly

Try to work out every day. Unless the doctor has recommended complete bedrest, working out or taking a walk regularly is good for you. It increases the blood flow to the placenta and the uterus, keeping the level of amniotic fluid in check.

8. Amnioinfusion

This is a medical procedure where sterile fluid is injected into the womb to help increase amniotic fluid levels.

9. Early delivery

In severe cases of low amniotic fluid levels, early delivery may be necessary to prevent complications such as umbilical cord compression and fetal distress.

Food to Increase Amniotic Fluid During Pregnancy

While there is no specific list of foods that are known to directly increase amniotic fluid levels during pregnancy, maintaining a healthy and balanced diet can support overall fetal development and fluid production. Here are some nutrient-rich foods that are beneficial during pregnancy:

1. Water

Staying hydrated is crucial for maintaining amniotic fluid levels. Aim to drink at least 8-10 glasses of water daily. It is also said that coconut water increases amniotic fluid, so you can also consume it during pregnancy for this and many other benefits.

2. Fruits and vegetables

These provide essential vitamins, minerals, and antioxidants. Opt for hydrating options like watermelon, cucumber, oranges, and berries.

3. Healthy fats

Foods rich in omega-3 fatty acids, such as salmon, chia seeds, and walnuts, can support fetal development and fluid production.

4. Protein-rich foods

Lean meats, poultry, fish, eggs, legumes, and dairy products are excellent sources of protein, which aids in fetal growth and fluid balance.

5. Whole grains

Foods like brown rice, quinoa, oats, and whole wheat bread provide essential nutrients and fiber, promoting a healthy pregnancy.

Remember, it's essential to consult with your healthcare provider for personalized advice regarding your specific situation.

FAQs

1. Is normal delivery possible with low amniotic fluid?

Normal delivery is possible with low amniotic fluid, but it depends on the specific circumstances. In some cases, low amniotic fluid levels (oligohydramnios) can be managed and monitored, allowing for a safe vaginal delivery. However, if there are concerns about the baby's well-being or complications arise, a healthcare provider may recommend a cesarean delivery.

2. How to increase amniotic fluid naturally?

While there is no guaranteed way to increase amniotic fluid levels naturally, several practices may help maintain healthy levels. Staying hydrated, consuming a well-balanced diet rich in fruits, vegetables, and healthy fats, and avoiding excessive caffeine and staying active with regular exercise can contribute to overall health and potentially aid in maintaining adequate amniotic fluid levels.

Conclusion

Pregnancy is a period of great anxiety, especially for first-time mothers. There is so much to take care of—eating a balanced diet, exercising, drinking plenty of water, taking supplements on time, and much more. However, one should guard against a low amniotic fluid level, which can happen anytime during pregnancy. So visit your doctor regularly and inform the doctor if anything feels different. There are a lot of ways of how to increase amniotic fluid to prevent oligohydramnios in pregnant women.
