Infantile colic is a frequent source of concern for parents, characterized by prolonged and unexplained crying episodes in otherwise healthy infants. Although this condition is generally benign, it can cause significant stress within families. Here is an overview of colic, their potential causes, and approaches to manage them.
What is colic?
Colic is defined as episodes of intense and prolonged crying, occurring at least three hours per day, three days per week for three weeks, in infants under five months of age. This crying, often inconsolable, frequently occurs late in the day and affects both breast-fed and bottle-fed babies. Around 20% of infants are affected, with symptoms generally peaking around six weeks before decreasing at the age of three to four months.
Why does colic occur?
The exact cause of colic remains unknown, although several hypotheses have been suggested. Gastrointestinal factors, such as an unbalanced intestinal microbiota or mild inflammation, play a role. Infants with colic often exhibit a reduced diversity of beneficial bacteria such as bifidobacteria and an increase in gas-producing bacteria. Additionally, intestinal permeability in babies may allow macromolecules to pass into the bloodstream, contributing to discomfort. Other possible causes include aerophagia, behavioral factors such as overstimulation, or even food sensitivities.
Treatments and management
Managing colic primarily involves supporting parents and taking measures to alleviate the baby's discomfort. Reassuring parents is essential, as this crying, although stressful, has no long-term consequences. Here are some common approaches:
Probiotics: Studies have shown that Lactobacillus reuteri DSM 17938 can significantly reduce crying time, particularly in breastfed babies. These probiotics rebalance the intestinal microbiota and reduce inflammation.
Dietary modifications: For formula-fed infants, partially hydrolyzed or low-lactose formulas can be beneficial, although their effectiveness varies. For breastfeeding mothers, a low-allergen diet such as dairy-free may be tried.
Soothing techniques: Methods such as rocking, swaddling or using white noise can help calm babies. While their effectiveness varies, they pose no risk.
Phytotherapy: Some plants like fennel and chamomile have shown promising effects in reducing crying, but their use must be supervised by a healthcare professional.
