What's with the occasional stomachache?

Chronic gastritis, duodenal ulcer, gastric cancer and other diseases may cause stomach pain from time to time.

1. Patients with chronic gastritis

may cause gastric mucosa damage due to autoimmune abnormalities, long-term drinking of coffee and other factors, causing chronic gastritis and frequent stomach pain.

2. Patients with duodenal ulcer

may cause chronic inflammatory damage caused by corrosion of duodenal mucosa due to Helicobacter pylori infection, abnormal gastric secretion and other factors, presenting repeated or periodic attacks.

3. Patients with gastric cancer

may cause gastric cancer due to long-term use of pickled smoked food, Helicobacter pylori infection and other factors, and sometimes stomach pain, dyspepsia and other symptoms.
