How is the small intestine affected by cholera?

Cholera, caused by the bacterium Vibrio cholerae, primarily affects the small intestine by producing a toxin that disrupts normal intestinal function. This toxin prompts the intestinal cells to secrete excessive amounts of water and electrolytes into the lumen, leading to severe diarrhea and dehydration. The rapid loss of fluids and salts can result in electrolyte imbalances and, if untreated, can be life-threatening. Moreover, the damage to the intestinal lining can impair nutrient absorption, exacerbating the condition.
