Diabetes mellitus (DM) is very common in the United States, and the incidence as well as prevalence of this disease are increasing. DM is not only a risk factor for cardiovascular and pulmonary conditions, but is also linked with several digestive complications. Among digestive complaints, constipation occurs in approximated two-thirds of patients with DM, making constipation the most common gastrointestinal (GI) complaint among type 2 diabetics. Consequently, these patients suffer abdominal pain, bloating, and have a lower health related quality of life when compared with patients without DM and GI symptoms.Constipated individuals may be reluctant to eat on a regular schedule which may worsen glycemic control as well as the symptoms related to an underlying diabetic enteropathy.
