Causes of epigastric fullness include physiological causes, such as overdiet, and pathological causes, such as intestinal obstruction, cirrhosis, metastatic tumor, etc.
1. Physiological causes: usually due to overdiet, resulting in a large amount of food actively in the stomach, which leads to epigastric bloating symptoms, generally do not need special treatment, the symptoms can be gradually relieved with the digestion and absorption of food, which is a normal physiological phenomenon.
2. Pathological causes: besides physiological causes, it may also be caused by intestinal obstruction, liver cirrhosis, metastatic tumor and other diseases.
(1) Intestinal obstruction: it is caused by intestinal inflammation, narrowing and other causes of intestinal obstruction, resulting in food and metabolites can not be discharged out of the body, a large number of collection in the intestinal tract, which leads to epigastric bloating symptoms.
(2) Liver cirrhosis: It is due to the increase of resistance of portal vein system caused by liver cirrhosis, which leads to the decrease of circulating blood volume and the increase of secretion of renin-angiotensin-aldosterone system, which reduces the water discharge from the kidney and leads to the formation of ascites by sodium and water retention, and then leads to the symptom of epigastric distention and fullness.
(3) Metastatic tumor: it is due to the tumor in other parts of the body metastasized to the abdominal cavity and formed new foci, with the increasing size of the tumor compressing the intestinal tube leading to the slowing down of intestinal peristalsis or obstruction, which leads to epigastric distension and fullness of symptoms.
Excluding physiological reasons, patients are advised to go to professional hospitals in time to find out the cause of the disease, and under the guidance of doctors for treatment.
