How can stress-induced diarrhea be managed?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Stress-induced diarrhea is often triggered by the gut-brain connection, where anxiety disrupts digestion. Two herbal remedies may help calm symptoms:

Si-Ni-San: A traditional Chinese formula that eases gut tension and supports the nervous system.
Berberine Hydrochloride: A plant compound shown to soothe intestinal inflammation and regulate bowel movements.

While these remedies can offer relief, diarrhea has many possible causes—from IBS and food intolerances to infections or more serious conditions. Guessing wrong can delay proper care. Before self-treating, take a free, instant, online symptom check to better understand what may be behind your symptoms and get clear guidance on your next steps.
