Are children born by caesarean section at risk for allergies?

LIMAPAGI – Every pregnant woman has the right to choose the course of the birth, whether normal or by caesarean section. However, a caesarean section is recommended for most patients with disease problems.

It’s important to note, however, that a new study found that babies born via cesarean section were low in Bacteroides, a form of bacteria that plays an important role in a child’s immune system development.

The results analyzed the levels of bacteria found in more than 1,400 Canadian infants that persisted from 3-4 months to 1 year of age, and subsequent allergy testing was performed at ages 1 and 3 years.

The results showed that infants with low levels of bacteria were, on average, three times more likely to be sensitive to peanuts by the age of 3 years.

“We found a causal link between caesarean section, persistent low levels of Bacteroides in the first year of life, and peanut sensitivity in infants,” said study author Hein Tun, assistant professor at the University of Hong Kong’s School of Public Health Health day, Saturday, June 26th, 2022.

The research team found that low levels of bacteria go unnoticed by many. In fact, it also affects low levels of sphingolipids (proteins that are important for the development of the immune system).

“The effect is more pronounced in children of Asian descent than in others,” he added.

Tun also learned an interesting fact that babies suffering from peanut allergies are most likely also related to diet changes.

“It could also be related to diet and environmental changes leading to westernization. But more research needs to be done,” he said.

Unsurprisingly, however, Lona Sandon, clinical nutrition program director at the School of Health Professions at the University of Texas’ Southwestern Medical Center, found that an association with a cesarean section is related to a peanut allergy.

“This is pretty common knowledge and consensus in the pediatric and nutrition world,” he said.

In his opinion, a caesarean section at birth requires fewer germs or bacteria and less breast milk.

“Deficiency in any of the above affects the immune system’s ability to mature and is linked to inappropriate immune responses such as food allergies,” he adds.

In addition, the research team warns that developing allergies in calves poses a long-term risk and can lead to asthma or eczema.
