Reflux in Babies

Babies have a short food pipe, a small stomach, spend a lot of time lying down, and drink a lot of liquid for their size. Overfeeding, swallowing air, and an immature valve all contribute. Sometimes reflux-like symptoms are actually caused by another problem, such as cow's milk protein allergy, so persistent or severe symptoms should be checked.

Spitting up is one of the most common reasons parents worry in the first months of life. Many healthy babies do it, often after feeds. In most babies it becomes less frequent over the first year as they sit up, eat more solid food and the valve matures.

In a happy, thriving baby the diagnosis is made from the history and examination, and no tests are needed. The doctor will ask about the feeding pattern, the vomit, growth and stools, and will plot your baby's weight on a growth chart. Tests (such as an ultrasound, a swallow study, or pH monitoring) are kept for babies with red-flag signs or poor growth, and are chosen by the doctor.

Simple steps are the first treatment and are usually enough.

• Burp your baby gently during and after feeds.

• Hold your baby upright for a short time after feeding, if they are awake and you are watching them.

• Avoid tight clothing or nappies around the belly.

• Always put your baby to sleep on their back on a firm, flat surface. Do not raise the head of the cot, use pillows, wedges or sleep positioners, and do not put a baby to sleep on their side or tummy to treat reflux, as these increase the risk of sudden infant death.

• Keep your baby away from tobacco smoke, which can make reflux worse.

Small changes to feeding can reduce spitting up.

• Continue breastfeeding if you are breastfeeding. Breast milk is still the best choice.

• Offer smaller, more frequent feeds rather than large ones, and do not overfeed. Follow your baby's hunger signs.

• If bottle feeding, check that the teat size lets milk flow at a comfortable pace and keep the teat full of milk to reduce swallowed air.

• Never thicken feeds or change formula on your own. Thickened or anti-reflux formulas are used only when your doctor advises.

• If you suspect a milk allergy, talk to your doctor before removing any food from your own diet or changing formula.

Most babies do not need any medicine for reflux.

• Acid-reducing medicines are not recommended for happy babies who simply spit up.

• Your doctor may try a short course of treatment only if there is confirmed reflux disease with feeding problems, poor growth or complications.

• Do not give your baby any medicine, herbal drink, or home remedy unless a doctor has advised it.

• The doctor decides the medicine, dose, and how long to use it, and will review whether it is still needed.

Procedures are rarely needed.

• Tests such as an upper GI contrast study, ultrasound, or endoscopy are only used when red flags or poor growth suggest another cause or a complication.

• Surgery is considered only in very rare cases of severe reflux that does not respond to other treatment.

For most babies the outlook is excellent. Symptoms usually fade over the first year of life without any medicine. Babies with true reflux disease or an underlying cause (such as milk allergy) generally improve once the cause is identified and treated by the doctor.

• Is my baby's spitting up normal for their age?

• Is my baby gaining weight as expected?

• Could a milk allergy be causing these symptoms?

• Does my baby need any tests or medicine, and for how long?

• Which signs mean I should come straight to the emergency department?
