Chronic diarrhea lasts longer than how many days?

• A. More than 30 days
• B. More than 7 days
• C. Less than 7 days
• D. 7-14 days

Answer: (A)

Chronic diarrhea is defined by how long it lasts. When diarrhea persists beyond a month, it signals a non-acute, ongoing problem rather than a short-lived illness. That’s why this option fits best: it specifies a duration longer than a month, which in many practice questions is the cutoff used to label diarrhea as chronic. Shorter time frames describe acute or subacute processes and point to different etiologies, while a duration lasting well beyond a month prompts consideration of conditions like inflammatory bowel disease, malabsorption, chronic infections, medication effects, or other systemic issues.
