acute diarrhea的意思|示意

Acute diarrhea is a medical condition that results in frequent and loose bowel movements over a period of two or more days. It is also known as acute watery diarrhea (AWD) and is one of the most common manifestations of gastrointestinal illness. Acute diarrhea is caused by infections and often resolves within a few days without any treatment.

Acute diarrhea can be caused by a number of factors, including bacteria, viruses, parasites, or a toxin. Bacterial infections, such as Salmonella, Shigella, and Campylobacter, are the most common cause of acute diarrhea in adults and are usually spread through contaminated food and water. Viral infections, such as rotavirus and norovirus, are the most common cause of acute diarrhea in children. Parasites, such as Giardia and Cryptosporidium, can also cause acute diarrhea. Acute diarrhea can also be caused by a toxin, such as from ciguatera fish poisoning or produce contaminated with harmful bacteria.

The most common symptom of acute diarrhea is frequent, loose bowel movements. Other symptoms may include abdominal cramps, nausea, vomiting, and low-grade fever. It is important to seek medical care if symptoms persist beyond a few days or if there is any blood or mucus present in the stool.

Treatment of acute diarrhea depends on the underlying cause. If an infection is suspected, antibiotics may be prescribed. For viral infections, antiviral medications may be used if available. Other treatments, such as antidiarrheal medications and oral rehydration solutions, may be used to ease symptoms. It is also important to drink plenty of fluids to prevent dehydration.
