Despite decades of research, the exact reason why babies get colic remains a mystery. Experts believe that there is no single cause. Instead, colic pain in new born baby is likely the result of several contributing factors.
Here are some of the most widely accepted theories by medical professionals:
1. An Immature Digestive System
A newborn’s gastrointestinal system is still developing. Food moves quickly through their small intestines, which can lead to uncomfortable muscle spasms. Furthermore, they may lack the healthy gut bacteria needed to break down food smoothly, leading to temporary digestive distress.
2. Swallowing Too Much Air (Gas)
While gas does not necessarily cause colic, colicky babies often swallow excess air during their crying spells. This trapped wind can cause severe bloating and discomfort, further prolonging the crying episode.
3. Overstimulation
Newborns have immature nervous systems. They are suddenly exposed to a world full of bright lights, loud noises, and new sensations. By the end of the day, a baby may simply become overwhelmed and overstimulated, leading to an emotional release through crying.
4. Food Allergies or Intolerances
In some cases, colicky behaviour is linked to what the baby is eating. Breastfed babies might be sensitive to certain foods in their mother's diet, such as dairy, caffeine, or spicy foods. Formula-fed babies might have a mild intolerance to the milk proteins found in standard baby formulas.
5. Infant Acid Reflux
Gastroesophageal reflux disease (GERD) in infants happens when stomach acid flows back up into the oesophagus. This can cause a burning sensation that triggers severe crying spells.
