Acute diarrhea is defined as having three or more loose or watery stools per day.
This condition typically starts abruptly and lasts for a short period, usually a few days to a week. While uncomfortable, acute diarrhea is often caused by infections and resolves on its own. However, it's important to stay hydrated and monitor your symptoms.
Causes of Acute Diarrhea
Diarrhea can stem from a variety of causes, including:
- Infections: Bacteria, viruses, or parasites are common culprits. These infections can be contracted through contaminated food or water (food poisoning). For example, norovirus and rotavirus are common viral causes.
- Medications: Some medications, such as antibiotics, can disrupt the gut's natural balance and lead to diarrhea.
- Food intolerances: Lactose intolerance, for instance, can cause diarrhea after consuming dairy products.
- Other Factors: Stress, anxiety, and changes in diet can also trigger acute diarrhea.
Symptoms and When to Seek Medical Attention
Besides frequent watery stools, other symptoms of acute diarrhea may include:
- Abdominal cramps and pain
- Nausea and vomiting
- Fever
- Dehydration
While most cases resolve without medical intervention, it's crucial to seek medical advice if you experience:
- High fever (over 101°F or 38.3°C)
- Blood in your stool
- Severe abdominal pain
- Signs of dehydration (decreased urination, dizziness)
- Diarrhea lasting longer than a few days
Duration and Resolution
Diarrhea caused by an infection generally appears between 12 hours and four days after exposure and typically clears up within three to seven days.
