Gastric atrophy moderate is due to the gastric mucosa when stimulated, triggering mucosal congestion, edema and even erosion, in the long run will cause chronic gastritis. If chronic gastritis is not treated in time, the situation will gradually deteriorate, and even lead to gastric mucosal gland atrophy, gastric mucosa thinning, etc.. Chronic gastritis is mostly due to the gastric mucosa irritation and erosion, congestion, edema and so on. Chronic gastritis is clinically divided into superficial gastritis and atrophic gastritis. Gastroscopy of superficial gastritis shows that the gastric mucosa is congested, edematous and even with white mucus. Atrophic gastritis mucosal glands atrophy, thinning, surface rough granular.
