What Are Fetal Hiccups?

Fetal hiccups are small, rhythmic movements that occur when a baby’s diaphragm contracts inside the womb. Just like hiccups in newborns and adults, they create a bouncing sensation and since the baby is still inside the womb, these hiccups are also felt by the mother.

Studies suggest that fetal hiccups play a role in preparing the baby’s lungs for breathing after birth. These small spasms help strengthen the diaphragm which is an important muscle for respiration. Furthermore, these hiccups also help in the neuromuscular development of the diaphragm.

What Does It Feel Like?

Unlike the unpredictable kicks or rolls a baby makes, hiccups occur in a steady pattern, almost like a heartbeat. The sensation can feel like tiny, rhythmic jumps inside the womb and may be noticeable in the same spot repeatedly.

Some women may find this experience amusing whereas others may find it distracting, especially if hiccups occur frequently or if they last for longer periods. Nonetheless, fetal hiccups are nothing to be worried about and are generally a sign of a healthy fetus.

Why Do Babies Get Hiccups in the Womb?

There are several possible reasons why babies get hiccups in the womb:

Lung Development: Hiccups help in the development of a baby’s diaphragm and respiratory muscles.

Swallowing and Digestive Practice: Babies begin swallowing amniotic fluid in the womb, which can sometimes lead to hiccups.

Nervous System Maturation: The baby’s brain and nervous system regulate movements, including the diaphragm’s contractions and hiccups might be a sign that these systems are developing properly.

Umbilical Cord Compression (Rare Cases): In some cases, frequent and prolonged hiccups can be a sign of umbilical cord compression. However, this is very rare and most fetal hiccups are completely normal.

Should You Be Worried?

In most cases, fetal hiccups are a normal and healthy part of pregnancy. They are especially common in the second and third trimesters and usually last only for a few minutes.

However, if you notice a sudden change in the frequency, intensity, or duration of your baby’s hiccups, especially after the 32nd week of pregnancy, it’s a good idea to check with your doctor.

How to Stop Them?

Fetal hiccups are harmless and typically resolve on their own, however, if you find them distracting, here’s how you can minimize them:

  • Change Positions: Shifting your posture or lying on your side may help your baby adjust and stop hiccups.
  • Drink Water or Eat a Snack: Some mothers find that drinking water or having a light snack can help calm their baby’s hiccups.

Conclusion

Fetal hiccups are a common and natural part of pregnancy. These hiccups are a sig that the digestive, repiratory and the nervous system of your baby is developing normally. They can sometimes feel repetitive or even distracting but they are completely harmless.

However, if you notice a significant change in their frequency or duration, you should always discuss it with your doctor. It's always better to be safe when it comes to the tiny developing human inside you.
