Paris: Heartburn is a common occurrence during pregnancy, since progesterone – the hormone produced by the placenta, which relaxes the smooth muscles of the uterus –

also relaxes the valve that separates the esophagus from the stomach, allowing gastric acids to seep back up, which causes that unpleasant burning sensation. To curb this, pregnant women mostly resort to antacids as the first option to aid quick recovery from the unpleasant feeling. But is that a wise move? A study has revealed that antacids consumed by pregnant women could raise the risk of asthma in their children by 33 percent. However, it remains unclear whether the medication itself, or some other factor, is responsible for that increased risk, researchers reported in the Journal of Allergy and Clinical Immunology. “This association does not prove that the medicines caused asthma in these children,” said Aziz Sheikh, co-director of the Asthma UK Centre for Applied Research at the University of Edinburgh and co-author of the study. “Further research is needed to better understand this link.” The study published today suggested that certain drugs can block this acid reflux, and have long been thought not to affect the development of the baby. Previous research had inconclusively pointed to an increased risk of allergies in offspring due to an impact on the immune system.
