Mild active phase of atrophic gastritis refers to the period when gastritis is occurring, typically caused by improper diet. This might be due to overeating or consuming greasy, spicy, and irritating foods, leading to exacerbation of the condition. Clinical manifestations include stomach pain, nausea, vomiting, and decreased appetite, which are inevitably linked to daily life habits. Furthermore, mental stress, excessive pressure, staying up late, and overfatigue can also have an impact.
