However, having instant diarrhea after drinking water may be a sign of chronic diarrhea. Diarrhea is related to several diseases. Irritable bowel disorder, dumping syndrome, and an increased gastrocolic response are among the potential causes of instant diarrhea after drinking water. Chronic diarrheal diseases like celiac disease might cause diarrhea after consuming water.

  • Unusual loose or watery feces are a sign of diarrhea.
  • Bacteria, viruses, or parasites are the most common causes of diarrhea.
  • Digestive system problems can potentially be the cause of chronic diarrhea.
