How do I know if diarrhea is serious?

When Is Diarrhea Serious?

Most of the time, an upset stomach and loose stools clear up on their own within a day or two. However, it is important to know when a common bug turns into something that requires a medical professional. If you are an adult, you should see your doctor if your symptoms stick around or if certain red flags appear.

Pay close attention to how long you have been feeling unwell. If your diarrhea persists beyond two days with no signs of improvement, it is time to get checked out. A major risk with frequent fluid loss is dehydration, so watch out for extreme thirst, dry mouth, or dizziness.

Certain symptoms mean you should seek medical attention right away rather than waiting two days. You should consult a healthcare provider immediately if you experience severe abdominal or rectal pain, notice bloody or black stools, or develop a fever above 102 F (39 C). Listening to your body and catching these warning signs early helps ensure you stay safe and recover quickly.
