Symptoms of duodenal and gastric ulcers

The main symptoms of duodenal ulcers include: 1. Upper abdominal pain: Pain often occurs when the stomach is empty or during hunger. It is characterized by regularity and seasonality; the time of daily abdominal pain is generally fixed, usually 3-4 hours after the stomach is emptied, i.e., 3-4 hours after meals or at night. 2. Acid regurgitation: Due to excessive gastric acid secretion, patients frequently experience discomfort such as acid regurgitation and stomach distension; symptoms may be relieved by eating or taking antacids. 3. Loss of appetite: Severe symptoms such as stomach pain and bloating can affect the patient's appetite. 4. Black tarry stools or vomiting blood: If the ulcer surface becomes eroded and bleeds, black stools or hematemesis may occur. These symptoms not only affect the patient's quality of life but may also signal worsening of the condition. Therefore, if related symptoms appear, timely medical examination and professional treatment are necessary.
