Gastroparesis requires hospitalization when there is severe pain, bleeding, pyloric obstruction, or cancer. Most gastric problems are characterized by bloating, acid reflux, and indigestion, and are associated with gastritis and gastric ulcers, which can be improved with medication and therefore do not require hospitalization. When the pain is severe, the patient should be alerted to the presence of acute gastric dilatation and gastric torsion, which require endoscopic restoration and therefore require hospitalization. When patients with gastric diseases vomit blood, they should be alerted to gastric perforation, gastric fundal vein bleeding and other diseases, which require endoscopic hemostasis treatment and therefore require hospitalization. Part of pyloric obstruction is caused by scarring in the pylorus area, which is ineffective in drug treatment and needs to be relieved by surgery, which also needs to be treated in the hospital. When stomach cancer occurs in the stomach, it needs to be surgically removed, and should be combined with radiotherapy and chemotherapy, and these patients should also be hospitalized.
