Is lower left abdominal pain and frequent flatulence in men caused by gastritis or colitis?

The specific characteristics are as follows: 1. Gastritis features: Gastritis typically presents with pain in the upper middle abdomen, bloating, belching, nausea, and vomiting. If the patient also experiences decreased appetite, stomach pain, and bloating, gastritis is more likely. Gastritis is usually caused by improper diet, Helicobacter pylori infection, and other factors. 2.
