What is silent reflux? Treatment & Symptoms

Section: Baby Health

When you have a newborn, seeing them distressed or upset is one of the hardest things you have to go through as a parent.

You've probably heard of reflux where a baby spits back up milk after feeding. Although seeing your baby be sick can be alarming, it is very common. In young babies, there’s a weakness in the band of muscles connecting the windpipe with the stomach. These muscles act as a valve and if this valve doesn’t shut properly, milk travels back up, causing vomiting.

Reflux can make babies very uncomfortable and irritable, perhaps resulting in frequent crying. The excessive and uncontrollable crying, often caused by general stress and abdominal discomfort, is referred to as colic and many believe there is a link between the two. But what about silent reflux?

What is silent reflux?

Silent reflux is effectively the same as reflux but the baby does not vomit or spit the milk back up so the symptoms are much less obvious. This means that stomach acid is causing discomfort, often behind the breastbone. It can make your babies throat sore or burn, so if they are coughing then this is one of the main symptoms that they do tend to display.

As symptoms of silent reflux do not appear, it is a relatively unknown phenomenon which means it might go unnoticed, misdiagnosed or mismanaged. However, as a parent, you're likely to know your baby and know when something is wrong.

Traditional acid reflux is known as gastroesophageal reflux disease (GERD), whereas silent reflux is often referred to as laryngopharyngeal reflux (LPR). According to Web MD "Silent reflux is common in infants because their sphincters are undeveloped, they have a shorter oesophagus, and they lie down much of the time."

If silent reflux persists it can cause long-term irritation or damage. Examples of complications in babies are:

Silent reflux complications:

  • Narrowing of the area below the vocal cords
  • Contact ulcers
  • Recurrent ear infections from problems with eustachian tube function
  • Lasting buildup of middle ear fluid

If your baby has persistent symptoms then it is best to visit your GP to seek advice and treatment for silent reflux.

What are the symptoms of silent reflux?

The NCT says silent reflux refers to the "condition where no outward symptoms of reflux appear, which can make diagnosis difficult. Babies show signs of being in pain, especially when not upright, and may have a persistent cough". However, your child may exhibit some of the symptoms of silent reflux which will make it easier for you to understand what is wrong.

The symptoms of reflux:

  • Vomiting
  • Feeding difficulties
  • Failure to thrive
  • Irritability and crying
  • Coughing or a sore throat
  • Breathing problems

What are the treatments or remedies for silent reflux?

There are certain treatments that can be prescribed by your doctor for reflux, colic or silent reflux. However, the condition and symptoms do often tend to deteriorate over time as your baby grows. Once your baby is older, their muscles develop further and they will spend more time sitting up which should help to prevent acid rising up in their throat.

If formula feeding, sometimes doctors or health visitors can put your baby on a thicker formula which might be easier for your baby to keep down. GP's may also prescribe an infant antacid to neutralise the acid in your baby's stomach.

9 simple remedies for silent reflux:

1) Gentle movement

Putting your baby in the sling or pushchair and gently moving them can help with reflux and encourage them to settle. Babies often prefer moving to sitting or lying still. Crying tends to make reflux worse and carried babies often cry less because they are close to you and upright.

2) Frequent, small feeds

Feeding your baby less but more frequently could stop them getting too full which will mean they are less likely to struggle to digest the milk.

3) Avoid tight clothing

Tight clothing can also put extra pressure on babies sensitive tummies so it is best to put them in loose clothing if they frequently suffer from reflux.

4) Relax and have quiet time

After a feed try and have half an hour of quiet and still relaxing time with your baby. This is especially important for formula fed babies as it is digested at a slower rate than breastmilk so they might need longer to settle.

5) Try and keep your baby upright

Try and keep your baby upright for half an hour after a feed. This can reduce reflux as gravity is more likely to keep the milk down.

6) Baby massage

Baby massage has been known to improve symptoms of reflux and colic. According to the NCT baby massage has several other benefits to parents: 
  • Becoming more confident in handling their child and better at recognising their needs.
  • Improved positive interaction with their baby.
  • A great way for partners, family members and carers to bond with baby.
  • Improved sleep for their baby.

7) Think about travel

Car seats and travel systems can often make reflux worse as babies tend to slump when in them, especially when asleep. Slumping puts more pressure on their precious tummies and they are more likely to feel the pain of rising acid. Try and avoid travel directly after feeding and buy a car seat that prevents slumping as much as possible.

8) Sleeping on their side

If your baby is old enough to roll over, it is safe for them to sleep on their side which might help with the symptoms of reflux. However, do not put your child on their side unless you are sure they do have the ability to roll.

9) Burping

If you are bottle feeding you can try burping your baby gently every few minutes during a feed. If you are breastfeeding, try gentle burping after a feed or if you are swapping sides.
