Understanding why your baby regurgitates clear liquid

You have probably noticed that your baby regularly regurgitates clear liquid. This phenomenon is perfectly normal in newborns and can be linked to several factors. In this article, we examine the possible causes of this situation and offer advice on how to deal with it.

What explains why my baby regurgitates clear liquid?

First of all, it is essential to understand exactly what this clear liquid is and where it comes from. This liquid is in fact acidic gastric fluid, which occurs naturally in the stomach. In very young babies, it is possible that the digestive system is not yet fully developed and mature, which can lead to prolonged reflux of acidic gastric fluid into the mouth or even into the airways.

The causes of prolonged reflux in babies

Prolonged reflux in newborns is generally caused by immaturity of the digestive and muscular systems. Several reasons can explain this phenomenon:

A weak lower oesophageal sphincter: the circular muscle located between the oesophagus and the stomach may be too relaxed, causing gastric fluid to reflux into the oesophagus in the usual way.

An inappropriate position during feeding: if the baby's stomach is not properly filled and too much air is trapped in it, this can lead to regurgitation. It is important to feed the baby in a position that is slightly tilted forward.

A feeding pace that is too fast: too high a flow rate from the bottle or during breastfeeding causes the stomach to fill too quickly, leaving it no time to empty properly before the next feed.

Unsuitable foods: certain foods may not be well tolerated by very young babies, and can cause regurgitation. It is therefore recommended to introduce different types of food gradually when the baby begins to diversify their diet.

What are the consequences of this prolonged reflux in my baby?

In some children, prolonged reflux poses no risk to their health; however, it is important to remain vigilant regarding the possible consequences:

Irritation of the oesophagus: gastric fluid contains acid, which can irritate the walls of the oesophagus and cause persistent discomfort.

Feeding difficulties: recurring episodes of regurgitation can disrupt mealtimes and make the baby harder to feed.

Poor weight gain: if the baby is unable to absorb sufficient nutrients, they may have difficulty putting on weight.

Respiratory infections: prolonged reflux of acidic gastric fluid into the airways can cause irritation and increase the risk of respiratory infections such as bronchiolitis or pneumonia.

How can I help my baby who is regurgitating clear liquid?

Even if prolonged reflux is generally not a cause for concern, it is important to find ways to relieve your little one's discomfort. Here are some tips to help you:

Adjust the position during feeding: make sure your baby is well tilted forward during breastfeeding or bottle feeding. This will help reduce the ingestion of air and aid digestion.

Slow down the pace of feeds: try to space feeds further apart and keep them smaller, so the stomach has time to empty properly.

Wind the baby after each feed: place them over your shoulder, supporting the head and neck well, then gently pat their back until they bring up wind. This will help release excess air and reduce reflux.

Consult a doctor if necessary: if, despite these preventive measures, your baby's reflux persists, do not hesitate to consult a healthcare professional who will be able to assess the situation and provide specific recommendations for your case.

In conclusion, it is perfectly normal for your baby to regurgitate clear liquid during their first few months. This situation is generally temporary and can be eased with simple adjustments to feeding habits and routines. Nevertheless, if you are concerned or the symptoms worsen, do not hesitate to consult a doctor for an appropriate diagnosis and personalised follow-up.
