What Causes Colic in a Baby?


As of 2015, the cause of colic is the subject of some debate, although mothers who smoke during pregnancy or postpartum elevate their babies' risk, notes BabyCenter. Some experts accredit colic outbursts to sensitivity and overstimulation in some babies, and others blame faulty balance in intestinal bacteria.

Anywhere between 8 and 40 percent of babies develop colic, and birth order, gender and the choice to breastfeed or use formula do not have any effect on colic. Those experts that consider overstimulation a cause suggest that, by the evening, the babies have had all the sensory input they can handle and cry uncontrollably, according to BabyCenter.

With regard to bacterial balance, some studies have shown that colicky infants have different microflora in the intestines than infants who do not develop colic. Probiotic treatments, particularly including Lactobacillus reuteri, has helped some babies beat colic symptoms. Talking to the pediatrician is a must before starting a probiotic regimen with an infant, though. Parents who believe their infants have colic should visit with the doctor about ongoing crying. Other problems, such as urinary infections or intestinal issues, could be the cause, and the doctor should also check normal growth and feeding, as stated by BabyCenter.
