Medications
Diarrhea may also be triggered by certain medications. [9] This type of diarrhea is often called drug-induced diarrhea. Drugs that present diarrhea as a side effect include both prescription and over-the-counter medications.
Antibiotics, for example, kill both bad and good bacteria in your gut. Some of the good bacteria cleared by antibiotics are part of your body’s natural microflora. Wiping them out upsets the bacterial balance in your intestines and may trigger diarrhea. Other medications that may cause diarrhea include antidepressants, anticancer drugs, and antacids containing magnesium.
Digestive Disorders
Several digestive disorders also often feature watery diarrhea as part of their symptoms. [10] This type of diarrhea is often chronic. Inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn’s disease, celiac disease, and irritable bowel syndrome (IBS) are digestive disorders that frequently cause diarrhea.
