We may think that feeding the baby frequently will help him grow better. But did you know that overfeeding is one of the biggest reasons of acid reflux? We, as adults, wrench at an acid reflux, imagine how difficult it must be for a baby! But overfeeding isn’t the only reason for a GERD.
What Is Reflux In Babies?
Acid reflux is the abnormal backflow of acid from the stomach to the esophagus through the lower esophageal sphincter. The sphincter is a muscular valve that prevents stomach contents from flowing into the esophagus. As infants have a poorly-developed sphincter that opens abnormally, it leads to a reflux of stomach acid.
Acid is caustic, and it stings and irritates the inner lining of the esophagus. Since the condition is caused by the malfunction of the oesophageal valve, it is referred to as gastroesophageal reflux (GER) or acid reflux or just reflux (1). If the problem persists, then it is called gastroesophageal reflux disease (GERD) (2).
Premature babies also suffer from GER as they have a poorly developed oesophageal valve (3). Reflux is quite common in full-term infants and some experts state that at least one in five infants experience GER at some point (4). Nevertheless, the American Academy of Paediatrics (AAP) states that GER in infants is normal and should not be a reason for worry (5).
What Causes Acid Reflux In Babies?
As you now know, reflux is caused by the abnormal opening of the lower oesophageal sphincter. It is the fundamental cause for GER, and certain conditions trigger the abnormal opening.
- Overfeeding the baby different foods such as formula, solids, and breastmilk can cause GER.
- Older infants eat different kinds of food and some may cause reflux. For instance, chocolate, peppermint, and high-fat foods cause the sphincter to stay open for longer while tomatoes and citrus foods stimulate the stomach to produce more acid. Both such foods cause reflux.
- Some congenital physical problems make the baby prone to GER. If the baby’s sphincter has a defect by birth, then the valve could be weak. Physical anomalies include problems in the angle at which the esophagus is attached to the stomach, diaphragm pressing against the stomach, or a hernia (6).
- Medication and external factors such as allergies may cause GER. Smoke from pollution and tobacco may also affect the sphincter valve (7).
Once you know the cause, it is important to learn the ways to spot the condition.
An infant with reflux will show the following symptoms of GER (8).
- Babies react to esophageal irritation by coughing and gagging, which is likely after a feed when the baby’s stomach is full.
- When the baby spits out some liquid, or food contents, with a burp, it is called wet burps.
- Just like wet burps, wet hiccups bring a small quantity of liquid into the mouth from the stomach.
- The baby arches the back or curls legs upwards as a reaction to the burning sensation in the abdomen.
- The moment you finish feeding breastmilk or formula, the little one becomes irritable, fussy, and a bit cranky.
- Gulping feels painful due to the reflux, and the infant may stop several times during the feed.
The above symptoms indicate normal levels of reflux. In mild reflux, the stomach acids may not reach the mouth and the baby will have no wet burps, hiccups, and coughing. Such reflux is unnoticeable and aptly called silent reflux (9). However, the baby will continue showing symptoms such as irritability that can point towards acid reflux.
In a case of severe reflux, the baby shows the below symptoms of GER.
- The baby has colic for over three hours a day but is otherwise healthy. Crying usually begins after feeding.
- If surplus acid flows into the esophagus, it can burn the inner lining of the stomach, leading to severe stomachache.
- The baby has heavy breathing with a wheezing sound. It is an indicator that the infant’s airways are constricted maybe due to reflux fluids trickling into the windpipe.
The AAP states that in normal reflux, the baby neither cries nor is in pain (10). GER seldom causes acute problems, but it is good to know about them.
When To See A Doctor?
Rush your baby to the doctor right away if you notice the following symptoms:
- Poor weight gain
- Poor appetite
- Wet burps/hiccups containing blood
These symptoms aid in the diagnostic process.
How Is Acid Reflux In Babies Diagnosed?
The doctor might use of these methods to check for acid reflux (11).
- he pH test or acidity levels of the esophagus indicate the presence of acid in the food pipe. The doctor uses a thin endoscopic probe inserted into the esophagus through the nose to detect the acidity levels.
- Chest X-ray verifies if liquids from stomach have passed into the lungs through the trachea. This is especially conducted if the baby is breathless.
- An endoscopy helps assess the esophagus for anomalies. Specialized endoscopes can evaluate the strength of the lower esophageal sphincter and determine if the valve is weak or not.
- Gastrointestinal tests are conducted in the case of more complicated gastrointestinal (GI) problems. One test is the barium test where the baby is given a liquid with barium, which makes the stomach and esophagus distinctly visible in an X-ray. Other tests track the passage of the liquid from the stomach to the intestines. Delayed emptying of stomach contents into the intestine can cause a full stomach to throw the food back into the esophagus leading to reflux.
A confirmed diagnosis of GER helps the pediatrician cure the condition appropriately.
How To Treat Acid Reflux In Babies?
The treatment of acid reflux involves the following medications and procedures:
- Oral medicines: The doctor will prescribe medicines such as H2-blockers that ease the production of acid in the stomach. Some H2-blocker medicines are cimetidine sold under the brand name Tagamet and ranitidine sold as Zantac. Another category medicines are proton-pump inhibitors that also reduce acid production by the stomach. A few proton-pump inhibitors are omeprazole sold as Prilosec and lansoprazole sold as Prevacid. These medicines are available over-the-counter. However, you must consult a doctor before giving it to the infant. The exact dosage and frequency of medicine will be recommended by the doctor after considering the baby’s age and intensity of reflux.
The baby could even be given medicines, such as metoclopramide (brand name Reglan) to digest the food faster and thus empty the stomach soon. It is taken before feeding or meals, and the dosage is decided by the doctor.
- Surgery: It is only performed on the infant as a last resort when no medicine works (12). The surgical procedure is called fundoplication, and the doctor recommends it when the baby’s reflux leads to severe breathlessness and loss of appetite. Surgery is conducted laparoscopically that is through small incisions in the stomach. The pediatric surgeon detaches the stomach from the esophagus and re-attaches it tightly, reducing the sphincter’s tendency to open prematurely.
The above treatment procedures provide relief from the acid reflux. The doctor will also suggest changes in the food and feeding style to handle the condition better.
Diet Management In The Case Of Acid Reflux
Proper diet care at home will support the treatment for acid reflux and helps the baby come out of the problem sooner than later:
- Switch baby formulas by trying different ones to see if it brings relief from reflux.
- Bring changes in the diet for better nutrition as infants tend to lose interest in food due to reflux, which adversely affects their appetite. Modifying the baby’s diet will help the little one gain adequate calories for growth and development. Parents can include rice cereal in the baby’s formula to provide extra carbohydrates. Rice is gentle on the stomach and digests easily. Doctors can prescribe a special high-calorie baby formula and it can be given even to breastfed infants who have inadequate calorie intake that cannot be replenished by breastmilk alone.
- If the baby suffers from an extreme case of reflux, then he will throw up anything he swallows. In such cases, he formula can be fed through nasogastric tube feedings at a hospital. The doctors insert a tube into the nose from where it goes into the esophagus and then the stomach. The formula is then directly sent to the stomach. In complicated cases of reflux or stomach surgery, the tube from the nose is pushed all the way to the intestine. The formula is directly pumped into the duodenum section of the small intestine. It is called nasoduodenal tube feeding. But these procedures are only used in severe conditions.
Most cases of reflux resolve with basic oral medicines and surgery while invasive feeding procedures are not usually required. Complex reflux should be dealt with importance and care because if left untreated it can lead to complications.
Complications Of Acid Reflux In Babies
An untreated severe acid reflux can eventually lead to the following problems.
- Gastroesophageal reflux disease (GERD) is a persistent condition. The baby will have acute symptoms that do not subside easily. Treatment with elaborate procedures such as surgery may be needed to cure the condition.
- Esophagitis is the repeated flow of acid that damages the inner lining of the esophagus making it red and swollen (13). The esophagus becomes prone to infections and also leads to severe discomfort when food passes through the food pipe.
- The liquid stomach contents may spill out from the esophagus and fall into the trachea (windpipe). As trachea leads to bronchioles in the lungs, it fills the lungs with fluids. This fluid may get infected by bacteria, eventually resulting in a severe ailment such as pneumonia.
- The baby’s diet is affected by reflux, and could lead to malnutrition. Babies with severe reflux gain height and weight in a slower pace than others. They could have poor immunity too.
Normal reflux does not lead to grave consequences. However, parents may feel tempted to try some home remedies.
Are Natural Remedies For Acid Reflux Safe?
Infants are different from adults, so never give a baby acid reflux medicines such as antacid or digestive pills. You could try homeopathic medication, but only after consulting a pediatrician. Do not use sleep wedges, pillows, and baby positioners for an infant with reflux. There is no scientific evidence that they help in preventing acid reflux. Instead, they increase the risk of sudden infant death syndrome (SIDS) (14). AAP recommends against the use of any “special” sleep surfaces and beds for the baby as they do not have any real benefits (15).
Do Babies Outgrow Acid Reflux?
Yes, an infant with GER will outgrow the condition by the age of 12 months. Only 1% of infants with GER continue to show persistent symptoms of acid reflux beyond a year (16).
That said, it is important to know how GER can be prevented.
How To Prevent Reflux In Babies?
Here are some things you can do for the baby to keep reflux at bay:
- Give your baby smaller feeds/meals: Instead of stuffing the baby all at once, give multiple small meals in a day, as they are easy to digest and tend to empty the stomach faster. This prevents overfeeding and thus acid reflux. If it is a breastfed baby, then you can nurse the baby for a lesser duration but at frequent intervals.
- Avoid certain foods: If the infant eats solids, then keep foods such as fatty foods, chocolates, citrus fruits, and tomatoes off the diet. These foods exacerbate the stomach acid production, leading to a higher risk of reflux.
- Buy a suitable bottle: Each baby has a different mouth structure, and not all bottle nipples may work. A good nipple and mouth alignment ensure the baby does not ingest air while feeding. Air is lighter and can force its way out from the stomach through the lower esophageal sphincter causing reflux with wet burps. To avoid this, try different bottles to zero in on the best one.
- Burp the baby between feeds: Give the baby time to burp and release air, as it prevents the buildup of pressure in the stomach. You can hold him in your arms and pat his back gently.
- Do not lay the baby down immediately after a meal: Hold the baby in a sitting or upright position for 30 minutes after feeding. This helps settle the food in the stomach and prevents it from moving upwards. If the baby eats solid foods, then give him a meal at least three hours before bedtime, as it aids in digestion. A baby should always be placed on his back when sleeping, even with reflux as it is the safest sleeping position for infants (17).
Babies recover from normal reflux and most infants never have a problem with it. In fact, babies with normal reflux are called ‘happy spitters’ because they are comfortable with the condition. Should you ever sense an increase in the reflex’s severity, take the baby to a doctor immediately. Some modifications in diet and oral medicines are all a baby needs to sail through the reflux ordeal.
