What could cause a stomach ache accompanied by diarrhea?

Stomach aches and diarrhea can be symptoms of conditions like Irritable Bowel Syndrome (IBS) with diarrhea. IBS is a common disorder that affects the large intestine and can cause cramping, abdominal pain, bloating, gas, and diarrhea. IBS is considered a functional bowel disorder, which means it is related to how the gut and brain work together, rather than a structural problem.

Functional bowel disorders, as discussed in the references, are a group of disorders characterized by persistent gut symptoms. They are not caused by any identifiable structural or biochemical abnormalities. These disorders can vary in their symptoms and severity, but they often involve abdominal pain and changes in bowel habits, such as diarrhea or constipation.

Other possible causes are related to infections such as gastroenteritis, colitis, or simply a stomach bug. Or food poisoning.

If you experience these symptoms, it is important to consult a healthcare provider to rule out other causes and to discuss management options. Keep in mind that while these symptoms can be uncomfortable, they are common and manageable with proper care.
