Acute gastritis is also a common and frequently occurring disease in gastroenterology, with a relatively sudden onset and more severe symptoms compared to other types of gastritis. The majority of causes are due to inappropriate diet, such as excessive consumption of cold, spicy food, or alcoholic beverages. Certain medications can also lead to this condition, such as non-steroidal anti-inflammatory drugs and corticosteroids. Symptoms often manifest as episodic upper abdominal bloating or colic, accompanied by acid reflux, heartburn, abdominal distension, etc. If acute gastric mucosal lesions occur, there are often signs of bleeding, such as black stools or even vomiting blood.
