What is the effect of gastrin?

Gastrin is a hormone that can be found in the body It is produced by gastric parietal cells and its main function is to stimulate the secretion of digestive acid Although this process involves the secretion of other hormones, gastrin is the main regulator of gastric acid The cells responsible for secreting gastrin are called G cells Eating food can stimulate the hormone When eating, food enters the stomach, and G cells stimulate the release of gastrin into the blood When the level of gastrin in the blood increases, it will induce the release of gastric acid This acid helps digest food When enough stomach acid is produced, the hormone levels begin to drop to their original levels In addition to the stomach, gastrin also plays an important role in other organs of the human body It also helps the intestines, liver and pancreas, but has less impact on these organs It stimulates the pancreas to secrete digestive enzymes, helps the liver to secrete bile, and helps food move through the lower part of the digestive tract in the gut Sometimes a doctor is needed to check the secretion of gastrin, especially when a digestive system disease is suspected For example, this test is used to check for abnormal cell growth in the pancreas or stomach wall In addition, it also helps to find intestinal tumors, and malignant anemia and other diseases Doctors usually test gastrin by intravenous injection of pancreatic juice This involves taking a sample of the patient's blood and giving it an intravenous injection of a digestive hormone called pancreatic juice Blood samples were collected again after injection, and at the first minute after injection, every 5 minutes The last blood sample was collected at the 30th minute Blood test reports are generally available in a few days High levels of gastrin may be a sign of cancer or blood disease In addition, there are other diseases associated with this hormone level For example, renal failure and certain types of ulcers On the other hand, low gastrin may also indicate health problems, such as hypothyroidism.
