Pye Henry Chavasse, Advice to a wife and mother in two parts (1881)
“ Heartburn is a common and often a distressing symptom of pregnancy. The acid producing the heartburn is frequently much increased by an overloaded stomach. The patient labors under the mistaken notion that, as she has two to sustain, she requires more food during this than at any other time; she consequently is induced to take more than her appetite demands, and more than her stomach can digest;—hence heartburn, indigestion, etc. are caused, and her unborn babe, as well as herself, is thereby weakened. ”
