What is the reason for waking up in the middle of the night with stomach pain?

Midnight stomachache may be related to dyspepsia, acute gastroenteritis, duodenal ulcer and other reasons. 1. Dyspepsia patients due to overeating before bed caused by dyspepsia, resulting in insufficient gastric power, food retention for a long time to stimulate gastric mucosa, can appear midnight stomachache. 2. Acute gastroenteritis patients due to eating cold, excessive heat, a large number of acidic food before bed caused by strong irritant food, due to gastric mucosa damage can appear midnight stomachache. 3. Duodenal ulcer patients due to Helicobacter pylori infection, long-term use of non-steroidal anti-inflammatory drugs and other reasons caused duodenal ulcer, due to midnight gastric acid content flow into the duodenum to stimulate the ulcer surface, can appear stomach ache.
