From the Guidelines

For an 8-month-old infant experiencing constipation pain, offering small amounts of water between feedings and trying fruit juices like prune, apple, or pear juice (2-4 ounces daily) is recommended. This approach is based on the current understanding of carbohydrate absorption from juice, as outlined in a 2017 study published in Pediatrics 1. The study suggests that the malabsorption of carbohydrate in juice, particularly sorbitol and other carbohydrates contained in some juices, can help increase the frequency and water content of stools for infants with constipation.

Some key points to consider when managing constipation in an 8-month-old infant include:

  • Increasing dietary fiber by introducing pureed fruits and vegetables if the baby has started solids
  • Gentle belly massage in a clockwise direction or bicycle leg movements to help stimulate bowel movements
  • A warm bath to relax the abdominal muscles and provide relief
  • Considering a switch in formula if the baby is formula-fed, after consulting with a pediatrician
  • Using glycerin suppositories made for infants occasionally, but only after consulting with a healthcare provider

It is essential to note that constipation in infants often occurs during dietary transitions, particularly when introducing solid foods or switching from breast milk to formula. If symptoms persist beyond a few days, if there's blood in the stool, if the baby seems unusually irritable, or if they're refusing to eat, it is crucial to contact a pediatrician promptly. Never give laxatives, mineral oil, or enemas without medical supervision, as they can be harmful to the infant's health 1.

From the Research

Treatment Options for Constipation in Infants

For an 8-month-old infant experiencing constipation pain, the following treatment options can be considered:

  • Polyethylene-glycol (PEG) is an effective treatment for infants over 6 months, as stated in the study 2
  • A sufficient dose of PEG for a long time is recommended, and in case of fecal impaction, a high dose of PEG can be used for the first few days
  • Education on adapting toilets and promoting daily bowel movements can help restore colic motility and prevent relapses

Dietary Changes

Dietary changes can also play a role in managing constipation in infants:

  • Prunes (dried plums) are high in fiber and may help promote healthy gastrointestinal function, as suggested in the study 3
  • Prune consumption has been shown to improve stool frequency and consistency in constipated subjects, and may be a promising intervention for managing constipation

Important Considerations

When treating constipation in infants, it's essential to:

  • Evaluate and address any psychological concerns that may be contributing to the condition, as mentioned in the study 2
  • Consider the potential risks and benefits of different treatment options, and consult with a healthcare professional before making any changes to the infant's diet or treatment plan
