The difference between gastroenteritis and gastritis, as referred here, likely concerns acute gastroenteritis and acute gastritis. The main symptoms of acute gastroenteritis include abdominal pain, nausea, vomiting, diarrhea, fever, etc. Acute gastritis mainly presents with symptoms such as abdominal pain, nausea, vomiting, and fever. The primary difference between the two is whether there are symptoms related to the intestines. The main causes of both are similar, primarily due to unsanitary dietary habits, leading to bacterial or viral infections in the stomach or intestines, causing a series of symptoms. Therefore, their treatments are also similar, focusing mainly on anti-inflammatory measures, fluid replenishment, and symptomatic treatment. Generally, recovery can be expected within two to three days of treatment.
