Indigestion can cause symptoms such as abdominal distention, belching, loss of appetite, and early satiety. When the function of the gastrointestinal system is disturbed, the peristaltic movement of the stomach is slow, and the food in the stomach is not better stirred, ground, and emptied by the stomach, which can lead to indigestion. The presence of food in the stomach can cause excessive pressure on the stomach wall, which can lead to a feeling of bloating in the stomach after eating. People with dyspepsia will feel early saturation after a small amount of food intake. The appearance of dyspepsia is very much related to gastritis and gastric ulcer esophagitis, and patients with a longer duration should undergo gastroscopy promptly to confirm the diagnosis of the condition.
