It is common for people who suffer from Irritable Bowel Syndrome (IBS) to also struggle with insomnia, especially when their IBS symptoms worsen.  In this small study the authors explored whether issues with sleep predicted next-day symptoms in women with IBS.  The research was performed on a sample of 24 women (aged 18-45 years) and it showed that poorer self-reported sleep quality significantly predicted worse next-day symptoms in women with IBS.
Take Away: This study adds further evidence that sleep quality is related to IBS symptoms.  There are many factors to consider when treating digestive issues and sleep may be a significant one.
