Enteritis is generally divided into chronic enteritis and acute enteritis. Acute enteritis usually has severe symptoms and develops rapidly. Common symptoms include abdominal pain, diarrhea, nausea, vomiting, and fever. In the case of chronic enteritis, symptoms can include mucous stools, bloody pus stools, and abdominal pain, as well as nausea and vomiting. Therefore, during acute enteritis, symptomatic treatment using anti-inflammatory drugs generally cures it within about three days. However, the treatment for chronic enteritis differs from that of acute enteritis since it involves a sterile inflammation, and anti-inflammatory drugs are generally not required outside the acute phase. So, when you are diagnosed with acute enteritis, do not worry; it can usually be quickly cured with some anti-inflammatory medication.
