Ever wonder what types of people are susceptible to having allergies over others? Based on a study on causes of allergies, there is now new information relating to who is more vulnerable to suffer from allergy symptoms. The study finds that factors before birth can affect your risk to having allergies. The study looked at children that developed allergies before the age of two. Researchers found that factors such as race, method of delivery, and a mother’s exposure to pets during the pregnancy, can all play a role in allergy risk of the child. The study ended up concluding that the levels of the antibody immunoglobulin E (IgE) were affected by these factors. This antibody is directly related to the development of allergies and asthma, with higher levels meaning increased risk. The study on causes of allergies further concluded that children whose mothers were exposed to indoor pets during pregnancy were had 28 percent lower levels of IgE compared with other babies from homes without pets. The study also found that IgE levels were 33 percent lower in infants of Middle Eastern, Asian, or European descent whose mothers were exposed to pets as compared to 10 percent lower in black infants whose mothers were exposed to pets. Additionally, IgE levels were 16 percent lower in infants whose mothers were exposed to pets and born vaginally when compared to infants whose mothers were exposed to pets but were born via cesarean section. This study shows that the different micro bacteria that young children are exposed to before birth can still have an effect on the development of allergies. The overall big picture is that exposure to some of these micro bacteria have an impact on immune system development in infants.
