Causes of stomach pain before and after meals

Stomachache generally refers to stomachache. Stomachache before and after meals may be caused by gastritis, gastric ulcer, duodenal ulcer and other diseases. The specific analysis is as follows:

1. Gastritis and

gastritis can cause gastric mucosa congestion, edema and exudation, affecting digestive function. Gastric acid will corrode gastritis before meals. Food will stimulate gastritis after meals, thus causing stomachache before and after meals.

2. Gastric ulcer and gastric

ulcer can lead to gastric barrier damage. Gastric peristalsis will occur before and after eating, thus stimulating gastric ulcer surface, leading to local nerve sensitivity, causing stomachache before and after meals.

3. Duodenal ulcer and

duodenal ulcer can cause duodenal redness and erosion. Gastric acid stimulation of duodenal site before eating can cause stomachache. Food rubbing duodenal ulcer site after eating can also cause stomachache.
