Introduction

Under normal circumstances, gastric bleeding, medically known as upper gastrointestinal bleeding, is one of the common emergencies in gastroenterology. It refers to bleeding occurring from the esophagus to the duodenum. In daily life, one should maintain regular eating habits, avoid overeating, reduce consumption of spicy or excessively hot foods, and avoid excessive alcohol consumption and the misuse of medications that can damage the gastric mucosa. Symptoms such as hematemesis (vomiting blood) and melena (black stool) may occur.

Generally, gastric bleeding, medically termed as upper gastrointestinal bleeding, is one of the common emergencies in gastroenterology, referring to bleeding occurring from the esophagus to the duodenum. A detailed explanation is as follows:

Gastric bleeding is a hemorrhagic disease caused by rupture of the gastric mucosa or blood vessels within the stomach. Symptoms mainly include hematemesis (vomiting of blood) and melena (black tarry stools), and severe cases may be accompanied by dizziness, palpitations, and other symptoms. There are several causes of gastric bleeding. Common ones include gastric ulcers and duodenal ulcers. When ulcerative lesions penetrate into blood vessels, they can cause vessel rupture and bleeding. Acute erosive hemorrhagic gastritis can also lead to gastric bleeding, often caused by excessive alcohol consumption or taking non-steroidal anti-inflammatory drugs (NSAIDs), which irritate the gastric mucosa and result in mucosal erosion and bleeding. Rupture of esophageal and gastric varices is another significant cause, often due to portal hypertension caused by liver cirrhosis, leading to dilation and rupture of the veins in the esophagus and stomach. In addition, mucosal damage on the surface of gastric polyps or gastric cancer invading blood vessels can also cause bleeding.

In daily life, it is important to maintain regular eating habits, avoid overeating, reduce intake of spicy and excessively hot foods, avoid heavy alcohol consumption, and refrain from misusing medications that damage the gastric mucosa. If symptoms such as hematemesis or melena occur, immediate medical attention should be sought to prevent delayed treatment. During treatment, follow medical advice regarding dietary adjustments, attend regular follow-up appointments, and monitor gastric recovery.

What are the ten major禁忌 (taboos) of eating plums?

On an empty stomach, the concentration of gastric acid in the stomach is relatively high. The organic acids in plums can further irritate the gastric mucosa, potentially causing discomfort such as stomach spasms and acid reflux, with more pronounced effects in individuals with weak gastrointestinal function. People with gastrointestinal disorders should consume plums cautiously; those suffering from conditions such as gastritis or gastric ulcers should avoid eating them altogether. Plums are considered cooling in nature and contain tannic acid, which may increase the digestive burden on the gastrointestinal tract.
