I’ve known a lot of adoptees who have stomach issues, who have trouble digesting some food, who struggle with constipation, or who often feel nauseous. I’ve known a lot of adoptive parents who have wondered what’s going on with their kids’ gastrointestinal health. A recent report, published in Development and Psychopathology, suggests that “children with early caregiving disruptions had distinctly different gut microbiomes compared to kids raised by biological caregivers from birth.”
The report from Columbia University is titled “Mind and Gut: Associations Between mood and gastrointestinal distress in children exposed to adversity.” The article is behind a paywall of $35. My information here is from the summary in Science Daily, “Gastrointestinal complaints in children could signal mental health problem,”and from PsychCentral, “Trauma-Related Gut Changes in Kids Tied to Future Mental Health Issues.”
According to the summaries, this “study is among the first to link disruption of a child’s gastrointestinal microbiome triggered by early life adversity with brain activity in regions associated with emotional health,” according to Dr. Bridget Callahan.
In other words, the brains of children who experienced trauma at an early age developed differently than children raised with their biological family, and one difference was the amount of gut biome diversity. We all want gut biome diversity: the more we have, the healthier our gut biome is, and the happier our stomachs and digestive system will be.
There is an increasing body of research suggesting that there is a link between mental health and gut bacteria. Much of the research is done on adults. This new research studied children adopted internationally before they were 2 years old, and compared them with children who were raised by their biological parents. “The children with past caregiving disruptions showed higher levels of symptoms that include stomach aches, constipation, vomiting, and nausea…Brain scans of the children also revealed that brain activity patterns correlated with certain bacteria. For example, children raised with (biological) parents had increased gut micro diversity, which is linked to the prefrontal cortex, a region of the brain associated with relating emotions.”
Of course there is more research needed. Still, this suggests something that a lot of folks in the adoption community have probably wondered about: trauma and disruptions in a child’s care can impact the brain and emotions, and thus can also affect changes to the gut, our digestive system. Those stomach aches and digestion problems may have their foundation in adversity, which affects brain development. Fascinating stuff. I hope the report gets in the hands of adoptees, adoptive parents, pediatricians, and other doctors. The mind-body connection is a powerful force.
