There is no data to support the idea that superficial gastritis causes weight loss of 20 pounds, so it is impossible to tell. Superficial gastritis generally refers to chronic superficial gastritis, and patients suffering from chronic superficial gastritis may experience wasting. Chronic superficial gastritis is a chronic superficial inflammation of the gastric mucosa caused by a variety of reasons. Helicobacter pylori infection is the primary cause, but it can also be caused by autoimmune factors, poor dietary habits, and other reasons. Due to the stimulation of inflammation, abnormal secretion of gastric acid can occur, resulting in symptoms such as burning sensation in the upper abdomen, indigestion and loss of appetite. Therefore, patients with chronic superficial gastritis may suffer from wasting. In addition, it is recommended that patients with chronic superficial gastritis go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
