First evidence of a possible association between gastric acid suppression during pregnancy and childhood asthma
I cannot begin to stress enough just how vitally important digestion is. Any attempt to block digestion with acid suppressive drugs (with the exception of those in the middle of a bleeding ulcer episode) is going to have long term, multiple, consequences on health. Stomach acid is absolutely essential to good health.
In this particular study we can see that these effects can even stretch to the unborn baby, increasing the risk for asthma.
