The common causes of epigastric obesity are physiologic obesity, hepatic space-occupying lesions, pyloric stenosis or obstruction, and pancreatic space-occupying lesions. 1. Physiological obesity: physiological obesity will be manifested as uneven distribution of body fat, especially the accumulation of abdominal fat is common, epigastric obesity is more obvious. 2. Hepatic space-occupying lesions: if the liver occupies a huge growth, it will also cause epigastric distension, which will be manifested as epigastric obesity, such as primary liver cancer, huge cysts of the liver and so on. 3. Pyloric stenosis or obstruction: due to pyloric stenosis or obstruction, all the food and gastric juices are often retained in the stomach, causing distension of the upper abdomen. 4. Pancreatic space-occupying lesions: Pancreatic space-occupying lesions can cause epigastric distension, severe pain and other symptoms. If you have epigastric obesity, you should consult a doctor in time and clarify the cause of the disease under the guidance of a professional doctor so as to avoid delaying the condition.
