Irritable Bowel Syndrome (IBS) is considered a functional gastrointestinal condition affecting the large intestine. Those with IBS may have diarrhea, constipation or a mix of both with abdominal pain and/or cramping. IBS symptoms can be brought on by factors such as stress, changes in gut microbiome, intestinal nerve issues, infection and more. Both migraine and IBS are conditions occurring more often in women and share other comorbidities such as depression and fibromyalgia. Both conditions affect the gut-brain-axis which could be a plausible connection between the comorbidities.
Studies have found those with migraine have a high prevalence of IBS ranging from 4% to 40%.”1
