Who was the only president who died in diarrhea?

The only U.S. president who is believed to have died from complications related to diarrhea is Zachary Taylor. He served as the 12th president from 1849 until his death in 1850. Taylor fell ill after consuming raw fruit and ice water, which led to severe gastrointestinal distress. He died just 16 months into his presidency, and while the exact cause of death has been debated, diarrhea was a significant factor.
