When is taking lemon water potentially counterproductive for acid reflux sufferers?

Right when the stomach is empty or digesting a large meal

While lemon water can stimulate digestive processes, the timing of consumption is crucial, particularly for individuals sensitive to acidity. For those experiencing acid reflux or frequent heartburn, introducing an acidic substance like lemon juice when the stomach is already empty or while it is actively engaged in breaking down a substantial meal can be problematic. In these scenarios, the introduced acidity may irritate the sensitive lining of the esophagus or the stomach itself, potentially worsening existing symptoms of GERD or discomfort. The stomach works hard to manage pH levels during digestion, and adding more acid at these vulnerable times can overwhelm this balance.
