Gastrin 0.6 that is, the value of fasting serum gastrin is 0.6ng/L, significantly lower than the normal value (20~160ng/L), which may be related to the stomach to produce lesions. Patients who further identify the cause of active treatment, the situation is not serious, if not active and timely treatment, resulting in aggravation of the condition, the situation is serious. Gastrin, also known as gastrin, can stimulate gastric mucosal cell proliferation and gastric sinus and intestinal motility, delaying gastric emptying. Studies have shown that the normal value of fasting serum gastrin is 20~160ng/L; it can be increased 2~3 times after meal. Gastrin test result is 0.6ng/L, obviously low, this condition is mostly seen in atrophic gastritis and gastroesophageal reflux disease. It is recommended to consult a doctor in time, and if necessary, carry out further examinations such as gastroscopy and carbon-13 breath test to understand the gastrointestinal mucosal lesions and the presence of Helicobacter pylori infection, to identify the causes and then actively treat the condition, the condition will not be very serious if it is under control. If gastrin is found to be low and no corresponding measures are taken, it may lead to aggravation or even deterioration of the condition, which will become serious. Therefore, if gastrin abnormality appears in the examination, you should improve the relevant examination under the doctor’s guidance, find out the cause and take corresponding measures to prevent the condition from worsening.
