Study type
Interventional
Description of intervention(s) / exposure
The aim of this randomized controlled trial is to assess whether coffee consumption accelerates the recovery of bowel function after cesarean section. Patients will be randomly assigned to study. Group 1 will be served as coffee group whereas group 2 with no treatment. The patients in study arm will drink 100 milliliter sugar and milk free-caffeinated coffee on the 2nd, 6th and 18th hour after surgery by nursery or doctor. The time to first bowel movements, first flatus and first defecation will be asked to patients three times daily by an evaluator blinded to the study allocation and results will be recorded.

Summary
Brief summary
Coffee is a popular drink in worldwide and improves general well-being. And it also positively affects central nervous system,cardiovascular system and reproductive system . It’s known that coffee stimulates colonic motor activity in healthy volunteers. There is a limited scientific evidence regarding its effects on gastrointestinal function, Two reports have shown that coffee consumption after open and laparoscopic colectomy is both safe and associated with reduced time of first bowel action. However , there is only one study investigated the effect on gastrointestinal function in patients after cesarean section according to a systematic review of literature. Thus, the primary outcome of this randomized controlled trial will be to assess mean time to first flatus, secondary outcome will be to assess mean time to first bowel movements and first defecation.
