Cesareans Weaken Gut Microbiota and Increase Risk of Allergies

Aug. 8, 2013 — Children who came into the world by Caesarean section are more often affected by allergies than those born in the natural way. The reason for this may be that they have a less diverse gut microbiota, according to a study by universities in Sweden and Scotland.

The researchers have followed gut macrobiota development in 24 children up to the age of two in the Swedish provinces of Östergötland and Småland, nine delivered through Caesarean and 15 delivered naturally, through vaginal birth. They used a type of molecular biology analysis, which gives a broad overview of the varieties of bacteria present in the intestines.

The results are presented in the scientific journal Gut, with Anders Andersson of the KTH Royal Institute of Technology and Science for Life Laboratory as the senior author. Other researchers in the study come from Linköping University, Karolinska Institutet (KI), Örebro University and the University of Glasgow, Scotland.
