Primarily, it depends on whether the bleeding has stopped. If the bleeding has ceased, the patient shows no signs of vomiting blood, and their gastrointestinal symptoms in the abdomen are slightly improving, generally, they can gradually start eating after about two days. If the patient still experiences vomiting of blood, or has black stools, increased frequency of bowel movements, heartburn, or if a gastroscopy confirms that the bleeding vessels from the gastric ulcer are relatively large, the duration of fasting might be comparatively longer. Therefore, the duration of fasting for a gastric ulcer bleed mainly depends on whether there is active bleeding in the patient.
