Dyspepsia: Dyspepsia is a clinical syndrome that manifests itself as epigastric discomfort, which is mainly caused by gastric dysfunction and visceral sensory hypersensitivity. Patients will experience epigastric pain, postprandial fullness and early satiety, and some of them will also be accompanied by gastrointestinal symptoms, such as diarrhea and constipation, which can lead to dry stools with mucus. 2.
