Hiccups are a common occurrence in babies, and while they can be a source of amusement for parents, they can also be a cause for concern, especially in premature infants. Premature babies, or preemies, are those born before 37 weeks of gestation. Due to their early arrival, preemies often have underdeveloped organs and systems, which can lead to various health issues, including frequent hiccups. This article aims to provide a comprehensive understanding of why preemies get hiccups, the potential implications, and how parents can manage and alleviate this condition.
What Are Hiccups?
Hiccups are involuntary contractions of the diaphragm—the muscle that separates the chest from the abdomen and plays a crucial role in breathing. These contractions are followed by a sudden closure of the vocal cords, producing the characteristic “hic” sound. In adults and full-term babies, hiccups are usually harmless and temporary. However, in preemies, hiccups can be more frequent and persistent, prompting parents to seek answers and solutions.
Causes of Hiccups in Preemies
1. Immature Nervous System
Underdeveloped Diaphragm Control
Premature infants have an immature nervous system, which means their brain and nerve functions are not fully developed. This immaturity can result in a lack of proper control over the diaphragm, leading to frequent and uncontrollable contractions, hence hiccups.
2. Gastroesophageal Reflux (GER)
Reflux and Hiccups
Gastroesophageal reflux (GER) is common in preemies because their lower esophageal sphincter (LES) is not fully developed. The LES is a muscle that acts as a valve between the esophagus and the stomach. In preemies, this valve may not close properly, allowing stomach contents to flow back into the esophagus, irritating the diaphragm and causing hiccups.
3. Feeding Practices
Feeding and Swallowing Air
Preemies often have difficulty feeding due to their underdeveloped sucking and swallowing reflexes. When they feed, they may swallow air, which can accumulate in the stomach and lead to distension. This distension can irritate the diaphragm and trigger hiccups.
4. Immature Digestive System
Digestive Development
The digestive system of a preemie is still maturing. An immature digestive system can result in slower gastric emptying and increased gas production, both of which can contribute to the occurrence of hiccups.
5. Respiratory Issues
Breathing and Hiccups
Preemies are prone to respiratory issues due to their underdeveloped lungs. Respiratory distress or rapid breathing can put pressure on the diaphragm, causing it to contract irregularly and leading to hiccups.
Implications of Hiccups in Preemies
Normal Developmental Phenomenon
Typical Developmental Stage
In most cases, hiccups in preemies are a normal developmental phenomenon and do not indicate any serious underlying condition. As the baby’s nervous and digestive systems mature, the frequency of hiccups usually decreases.
Potential Discomfort
Discomfort and Irritability
While hiccups are generally harmless, they can cause discomfort and irritability in preemies. Frequent hiccups can disrupt feeding and sleep patterns, making it challenging for both the baby and the parents.
Indicator of GERD
GERD and Health Concerns
If hiccups are accompanied by other symptoms such as frequent vomiting, coughing, irritability during or after feeding, or poor weight gain, they may indicate gastroesophageal reflux disease (GERD). GERD requires medical attention and management to prevent complications.
Respiratory Distress
Breathing Difficulties
In rare cases, persistent hiccups may be a sign of respiratory distress or other underlying health issues. Parents should monitor their preemie for any signs of breathing difficulties and seek medical advice if they are concerned.
Managing Hiccups in Preemies
1. Feeding Techniques
Optimal Feeding Practices
Adopting optimal feeding techniques can help reduce the frequency of hiccups in preemies. Parents can try the following:
Burp Frequently: Burping the baby frequently during and after feeding can help release any trapped air in the stomach.
Slow Feeding: Feeding the baby slowly and using a slow-flow nipple can prevent the baby from swallowing too much air.
Upright Position: Keeping the baby in an upright position during and after feeding can help reduce the risk of reflux and subsequent hiccups.
2. Smaller, More Frequent Feedings
Frequent Small Meals
Offering smaller, more frequent feedings can help prevent overfeeding and reduce stomach distension, which can trigger hiccups.

3. Pacifier Use
Sucking on a Pacifier
Sucking on a pacifier can help soothe the baby and may reduce the frequency of hiccups by promoting a regular breathing pattern and preventing air swallowing.
4. Gentle Stimulation
Soothing Techniques
Gently patting or rubbing the baby’s back can help soothe the diaphragm and reduce hiccup episodes. Parents should ensure they do this gently to avoid causing any discomfort.
5. Monitor and Adjust Feeding Position
Optimal Positioning
Adjusting the baby’s feeding position to ensure their head is elevated can help reduce the occurrence of hiccups. Parents can experiment with different positions to find the one that works best for their baby.
6. Consult a Pediatrician
Professional Advice
If hiccups are persistent or accompanied by other concerning symptoms, parents should consult a pediatrician. The doctor can evaluate the baby for any underlying conditions such as GERD or respiratory issues and provide appropriate management strategies.
When to Seek Medical Attention
Persistent Hiccups
Continuous Hiccups
If a preemie experiences persistent hiccups that do not improve with home management techniques, it is essential to seek medical advice. Continuous hiccups may indicate an underlying issue that requires medical intervention.
Associated Symptoms
Concerning Signs
Parents should be vigilant for any symptoms accompanying hiccups that could indicate a more serious condition. These symptoms include:
Frequent Vomiting: This could be a sign of GERD or other digestive issues.
Poor Feeding: Difficulty feeding or poor weight gain may indicate a need for medical evaluation.
Breathing Difficulties: Any signs of respiratory distress, such as rapid breathing or difficulty breathing, should be promptly addressed by a healthcare professional.
Irritability and Discomfort: Excessive irritability or discomfort during or after feeding may require medical attention.
Conclusion
Hiccups in preemies are a common occurrence and are usually a result of their immature nervous and digestive systems. While they are generally harmless, they can cause discomfort and may sometimes indicate underlying conditions such as GERD or respiratory issues. Parents can adopt various strategies to manage and reduce the frequency of hiccups, including optimal feeding techniques, frequent burping, and soothing practices. However, if hiccups persist or are accompanied by other concerning symptoms, it is crucial to seek medical advice to ensure the well-being of the preemie. Understanding the causes and implications of hiccups in preemies can help parents provide better care and alleviate their concerns, ensuring their baby’s healthy development.
