The primary symptoms of atrophic gastritis include upper abdominal distension and pain, post-meal fullness, early satiety, belching, acid reflux, nausea, and vomiting. Some patients may also experience weight loss, fatigue, anxiety, depression, and forgetfulness. Additionally, some may suffer from dizziness, weakness, and pale complexion. If the gastric mucosa is eroded or even bleeding, it can lead to gastric bleeding and result in anemia. In terms of treatment, the primary approach is the eradication of Helicobacter pylori, using a regimen that includes a proton pump inhibitor, two types of antibiotics, and a bismuth agent. Additionally, treatments include acid suppression, gastric protection, and enhancing gastric motility. Traditional Chinese medicine and herbal treatments are also very important methods for treating atrophic gastritis.
