The epigastric bulge bulging outward, the cause of many, common may be centripetal obesity, pyloric obstruction, liver disease and other causes. 1. Centripetal obesity: this disease is often caused by lack of exercise, long-term sedentary or addicted to greasy food, resulting in an increase in visceral fat, the patient’s fat accumulation in the abdomen, often manifested in the epigastric bulging outward. 2. Pyloric obstruction: If the pylorus is edematous and thus obstructed, food cannot pass through the digestive tract smoothly, thus affecting the digestive tract’s ability to digest and absorb. This can lead to a prolonged retention of food in the stomach, and gas can be released from the intestines when the food is broken down by gas-producing bacteria. When a large amount of food and gas accumulates in the upper gastrointestinal tract, it expands the digestive tract, causing the upper abdomen to bulge outward. 3. Liver diseases: Liver diseases that cause bulging and protruding epigastrium, such as massive liver cancer, hepatitis and other diseases, should be diagnosed in time. It is recommended that patients with bulging and protruding epigastrium should go to regular hospitals in time to improve the examination and follow the medical advice after clear diagnosis.
