What exactly is ‘explosive diarrhea’? - The Hill

What the report says

The Hill, citing Nexstar reporting, explained the phrase “explosive diarrhea” in the context of an ongoing FDA investigation into a multistate cyclosporiasis outbreak. The article said patients in numerous states have reported severe diarrhea, and medical experts described the phrase as nontechnical but useful shorthand for sudden, high-volume, often watery bowel movements that may come with gas and cramping.

Dr. Dean Blumberg of UC Davis Health told Nexstar the term is descriptive rather than an official diagnosis, and Dr. Deborah Plate of the Cleveland Clinic said clinicians often ask patients to characterize diarrhea because the details can point toward possible causes. According to the report, this more forceful and unpredictable type of diarrhea can be a notable sign of parasitic illness, including cyclosporiasis.

The Hill reported that cyclospora affects the small intestine’s lining, interfering with absorption of water and nutrients. Blumberg explained that excess liquid can move into the colon while unabsorbed carbohydrates ferment, producing gas and contributing to severe bowel movements. The report noted that dehydration and electrolyte loss are concerns, particularly for young children, older adults and people with weakened immune systems.

The article also said cyclosporiasis typically differs from some viral or bacterial illnesses because vomiting, fever and bloody stools are not common features. Unlike viral infections, it can be treated with antibiotics after medical confirmation, often through a stool sample, though symptoms may recur as the intestinal lining heals. Plate advised people to contact a healthcare provider if diarrhea continues for more than 24 hours.
