Abstract
Background: Food intake, accompanied by systemic and splanchnic haemodynamic changes, has only been studied in males. The extent to which splanchnic postprandial hyperaemia shows gender differences is unknown. Methods: We tested 1) the splanchnic hyperaemic response to food in females and 2) whether postprandial haemodynamic changes show gender differences. Twenty-four healthy women (aged 20-35 years) and 20 healthy men (aged 21-34 years) participated in the study. A liquid test meal (Ensure plus, 1.5 kcal/ml) was perfused intraduodenally for 75 min through an enteral feeding tube at a rate of 3 ml/min after a 45-min basal period. Blood flow parameters were measured using Echo-Doppler technology. Results: Basal diastolic arterial blood pressure was significantly (P
