Physiological reasons: when staying up late on an empty stomach for a long time, gastric acid will stimulate or corrode the gastric mucosa, causing stomach pain, nausea, vomiting, acid reflux and other symptoms; when staying up late, the brain is in a state of fatigue for a long time, resulting in functional disorders of the brain nerves, stimulating the sympathetic nerves, causing vomiting, nausea and other symptoms.

(1) Chronic gastritis: it is a chronic inflammatory lesion of gastric mucosa caused by lymphocyte infiltration as the main pathological feature, duodenal gastric reflux, Helicobacter pylori infection and other factors. Staying up late can cause an increase in gastric acid secretion, which further stimulates the congested and edematous gastric mucosa, causing symptoms such as gastric distension, nausea and vomiting.
