Constipation means different things to different people. For some people, it refers to the decrease in frequency of bowel movements. For others, it means difficulty in passing stools (straining) or incomplete evacuation. The frequency of bowel movements varies greatly from person to person, ranging from three per day to three per week.  From a medical standpoint, constipation is defined as fewer than three movements per week. Not current enrolling.

Constipation in adults may result from a variety of causes including poor diet, ignoring bowel movements, changes in lifestyle, laxative abuse, poor exercise, side effects of prescription medications as well as other underlying conditions such as irritable bowel syndrome.
Premier Research conducts research studies on investigational medication to treat constipation, secondary to a variety of causes.  If you are suffering from constipation, you may be eligible to participate in one of our research studies.
