Gastrin 17 of 8.3 is on the high side and is not normal. Gastrin 17 is secreted by G-cells in the gastric sinus, which is a kind of gastrointestinal hormone, stimulating the secretion of gastric acid and promoting the proliferation of gastrointestinal mucosa, and it is a key indicator for diagnosing the state of gastric function, and the reference value is from 0.7 to 7.60. If the value of gastrin is high, it suggests that the gastric mucosa is damaged, which may be related to chronic gastritis, gastrinoma and other factors. If the elevation is obvious and accompanied by symptoms such as acid reflux, nausea, vomiting, abdominal pain, etc., it is recommended to consult a doctor for a clear examination and cooperate with the doctor’s treatment. Dietary advice to light and easy to digest food, avoid eating cold, spicy, hard food, so as not to stimulate the gastric mucosa. In conclusion, if gastrin is found to be high, it is necessary to consult a doctor in a timely manner, and if necessary, perform a gastroscopy to avoid delaying the condition.
