Heartburn is a common occurrence during pregnancy, 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
A study has revealed that antacids consumed by pregnant women could raise the risk of asthma in their children by 33 percent.
Aziz Sheikh, co-director of the Asthma UK Centre for Applied Research at the University of Edinburgh said, "This association does not prove that the medicines caused asthma in these children."
To dig deeper, scientists from Edinburgh and Finland reviewed eight previous studies involving more than 1.3 million children, drawing on healthcare registries and prescription databases.
They found that children born of mothers taking antacids were at least a third more likely to have visited a doctor for asthma symptoms.
Asthma is a chronic lung disease that inflames and narrows the airways. It frequently starts in childhood.
Symptoms include wheezing, shortness of breath and coughing.
Jean Golding, an emeritus professor of paediatric epidemiology said, "It may be that the heartburn in itself may be the most important association rather than the drugs used to treat it."
