Overview

Intestinal cramping with diarrhea occurs when the gut dramatically accelerates peristalsis. The wave-like contractions that normally move food gently become forceful and frequent, producing pain between bouts of loose stools.

Possible Causes

Acute Gastroenteritis

common

Viral or bacterial infection causing intense cramping as the gut tries to expel pathogens.

IBS

common

Exaggerated gut contractions in response to stress, certain foods, or hormonal changes.

View Condition Details

Lactose Intolerance

common

Undigested lactose draws water into the intestines and is fermented by bacteria, causing cramps and watery diarrhea.

When It Is Serious

Bloody stools, fever above 102°F, severe dehydration, or abdominal rigidity suggest invasive infection or surgical condition.

When It's Likely Benign

Self-limiting episode after eating questionable food that resolves within 48 hours.
