WebDigestive hormones - Gastrin, Secretin, cholecystokinin, Gastric Inhibitory Peptide and Motilin; it helps and regulates the human digestive process. The presence of food in the stomach stimulates secretion of the gastrin into the circulatory system. Gastrin in-turn stimulates the secretion of gastric juice in the stomach. WebThus, taking the thyroid test in an empty stomach ensures that the levels of TSH and thyroid hormones accurately reflect the patient’s thyroid function. It is recommended to take thyroid tests early in the morning on an empty stomach, as the levels of TSH and thyroid hormones are at their lowest levels, and taking the test during this time ...
Along with the above-mentioned function, gastrin has been shown to have additional functions as well: Stimulates parietal cell maturation and fundal growth.
