When Diarrhea Becomes Chronic
Diarrhea that lasts for 4 weeks or more is considered chronic. While often harmless, it can sometimes indicate an underlying health issue. Paying attention to accompanying symptoms is key to knowing when to seek medical care.
5 Alarm Symptoms to Take Seriously
1. Blood in the stool 2. Unintended weight loss 3. Fever 4. Nighttime diarrhea 5. New onset after age 50. Any of these 'red flags' warrant prompt medical evaluation to rule out serious conditions like inflammatory bowel disease or even cancer.

Other Symptoms to Watch
While not always urgent, other symptoms to discuss with your doctor include severe abdominal pain, signs of dehydration, or diarrhea that interferes with daily life. Persistent changes in bowel habits should never be ignored, even if they seem minor.
When to Seek Immediate Care
Some situations require emergency medical attention. Seek care right away for severe abdominal pain, high fever (over 102°F), or signs of severe dehydration like extreme thirst, dizziness, or dark urine. These could indicate a serious infection or complication.
