How long must diarrhea persist to be classified as chronic?

• A. <7 days
• B. 7-14 days
• C. >14-21 days or chronic intermittent signs
• D. <14 days

Answer: (C)

The main idea here is how long diarrhea must last before we call it chronic. In practice, diarrhea is considered chronic when it persists beyond about three weeks (roughly 21 days). This option also recognizes that even if symptoms come and go, a pattern of ongoing or recurrent signs over time still fits the chronic category. So lasting longer than 14–21 days, or presenting as chronic intermittent signs, best describes chronic diarrhea. Shorter durations point to acute or subacute cases, where the issue may resolve with time or simple treatment.
