What are the symptoms of acute enteritis? The symptoms of acute enteritis can manifest in terms of gastrointestinal symptoms and systemic symptoms. The most common symptom in the gastrointestinal tract is diarrhea, which is the main symptom, varying in intensity, typically occurring several times a day or even more than 10 times. The stools are often yellowish watery diarrhea and may include mucous or bloody stools. In severe cases, it can also contain pus and blood. The second symptom is abdominal pain: The location of the abdominal pain is usually around the navel, and if the colon is affected, there can be pain on both sides of the abdomen. Abdominal pain can also be categorized as mild, moderate, or severe. Severe pain is generally caused by intestinal spasms, often accompanied by different degrees of abdominal tenderness. Other gastrointestinal symptoms include vomiting, nausea, or discomfort in the upper abdomen. Systemic symptoms: Generally, the body temperature of patients with enteritis is normal; however, if caused by an invasive pathogen or virus, there can be moderate fever. If high fever occurs, it should be distinguished from other diseases. Additionally, acute enteritis can also accompany symptoms like dizziness, headache, and weakness in limbs, among other signs of systemic infection. Frequent vomiting or severe diarrhea can lead to dehydration, electrolyte imbalances, disruption of acid-base balance, and in severe cases, a drop in blood pressure or even shock.
