Acute gastritis is caused by various reasons leading to acute inflammation of the gastric mucosa, primarily due to stress, medications, infections in the stomach, and bile reflux. The main symptoms include upper abdominal pain, accompanied by nausea and vomiting, often with enteritis causing diarrhea, bloody stool, and signs of dehydration. The treatment for acute gastritis is mainly symptomatic, with timely fluid replenishment through intravenous hydration. Additionally, bed rest is recommended, along with cessation of all gastric irritants in food or medications, and fasting if necessary. For abdominal pain, local heat application or the use of antispasmodic analgesics can be considered; generally, anti-infection treatment is not required.
