How Long Does Diarrhea Last and When Should You See a Doctor?
The duration of diarrhea varies depending on its underlying cause. Acute diarrhea, which typically lasts for a few days to a week, is often caused by viral infections or foodborne illnesses. In these cases, the condition usually resolves on its own as the body fights off the infection. If diarrhea is caused by bacterial infections or parasites, it may last longer, and antibiotics or other treatments may be necessary to clear the infection. Chronic diarrhea, defined as diarrhea lasting more than four weeks, can be a sign of more serious conditions, such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), or chronic infections, and requires a medical evaluation to determine the underlying cause.
It is essential to see a doctor if diarrhea lasts for more than a couple of days or if it is accompanied by severe symptoms like dehydration, persistent fever, blood in the stool, or significant abdominal pain. Additionally, if diarrhea leads to unintentional weight loss or if there are signs of an electrolyte imbalance, such as dizziness or confusion, it is important to seek medical attention promptly. For individuals with weakened immune systems, such as those with chronic diseases or those undergoing immunosuppressive treatments, prolonged diarrhea can indicate a more serious infection or health problem that requires immediate attention.
