There is a 0.6×0.8 mucosal whitening at the greater curvature of the gastric antrum, which may suggest gastric mucosal atrophy, gastric ulcer, gastro-sinusitis and so on. 1. Gastric mucous membrane atrophy: Long-term heavy drinking, consumption of stimulating food and drugs will stimulate the gastric mucous membrane, resulting in gastric mucous membrane damage. In the process of continuous repair, the gastric mucosa will atrophy, resulting in atrophic gastritis, which can be manifested as a whitish mucosa of 0.6×0.8 at the great curvature of the gastric sinus. 2. Gastric ulcer: long-term use of drugs that stimulate the gastrointestinal tract or bad habits, may lead to bile reflux, gastroesophageal peristalsis is not coordinated, thus inducing gastric ulcer. If the gastric sinus has an ulcer, the mucosal tissue is constantly destroyed, it may cause a 0.6×0.8 mucosal whitening in the great curvature of the gastric sinus. 3. Inflammation of the gastric sinus: eating too much cold, spicy, indigestible food can lead to abnormal secretion of gastric acid, stimulating the gastric mucosa, inducing inflammation of the gastric sinus. Under the stimulation of inflammation, it can lead to a 0.6×0.8 mucous membrane whitening in the greater curvature of the gastric sinus. There may be other reasons for the whitening of the mucous membrane in a 0.6×0.8 spot in the greater curvature of the gastric sinus, so you should consult a doctor in time to clarify the specific cause and get appropriate treatment if necessary.
