17 is very low?

Gastrin 17 is a gastrointestinal hormone secreted by g cells in the stomach, mainly distributed in the antrum of the stomach, followed by the fundus of the stomach. In addition, gastrin can also be secreted in the duodenum and jejunum mucosa. If gastrin 17 is secreted at a low level, atrophic gastritis is considered first, especially in patients with type A atrophic gastritis. Most gastric mucosa in the stomach body is atrophic, so the ability to secrete gastrointestinal hormones decreases, and the patient's digestive function will also decrease. Therefore, if this situation shows that gastrin 17 is obviously low, it may also be accompanied by decreased secretion of digestive juice such as gastric acid and pepsin, which seriously affects the patient's digestive function. It is best to carry out gastroscopy to make a clear diagnosis. Moreover, atrophic gastritis has the possibility of carcinogenesis, so we must pay great attention to it and actively carry out drug intervention.
