Babies born by caesarean section may be more likely to develop asthma than babies delivered naturally. A study in Switzerland involved 3,000 babies. Those born by c-section were about 80 percent more likely to develop asthma by the age of 8.

Doctors say babies delivered by c-section are not exposed to their mother's bacteria when they pass through the birth canal and that could explain the results.

The study in published in the journal Thorax.
