The effects of suckling on plasma somatostatin, insulin and gastrin values were evaluated in eight nursing women on the 3rd to 4th day postpartum. Plasma prolactin levels were also determined. Prolactin levels increased in response to suckling, as expected. Insulin levels also rose, whereas somatostatin and gastrin concentrations did not change after suckling. It is possible that the suckling‐induced hyperinsulinemia blunts the somatostatin response to suckling in humans.
