What specific factor is noted as a possible cause for diarrhea when consuming ginger?

Consuming large quantities.

Gastrointestinal side effects like diarrhea are frequently cited adverse reactions associated with ginger intake, particularly when consumption moves beyond typical culinary amounts. While ginger is generally helpful for settling an upset stomach in mild doses, excessive ingestion can overwhelm the system. The mechanism is thought to be related to the stimulating effect ginger has on gut motility and secretion. When consumed in large quantities, this stimulation can become overzealous, leading to an accelerated passage of contents through the intestines. This rapid transit time prevents adequate water absorption, resulting in loose stools or outright diarrhea, signifying that the individual's immediate tolerance level for the root has been surpassed.
