Frequently Asked Questions

What digestive symptoms should not be ignored?

Persistent abdominal pain, blood in stool, black stool, unexplained weight loss, ongoing vomiting, trouble swallowing, severe diarrhea, or symptoms that wake you at night should be evaluated promptly.

How do I know if I need a gastroenterologist?

You should see a gastroenterologist when symptoms such as reflux, bloating, constipation, diarrhea, abdominal pain, or rectal bleeding are frequent, worsening, or not improving with basic care.

What tests are used for digestive symptoms?

Testing may include blood work, stool studies, breath tests, imaging, endoscopy, colonoscopy, or other GI procedures depending on your symptoms, age, risk factors, and medical history.

Can stress cause digestive symptoms?

Stress can worsen symptoms such as cramps, bloating, reflux, constipation, and diarrhea. However, recurring or severe symptoms should still be evaluated to rule out underlying GI conditions.
