Irritable Bowel Syndrome with Constipation
About This Study:

Who Gets Constipation? About 90% of healthy adults have bowel movements at regular intervals ranging from three times a day to three times a week.* These adults also experience constipation occasionally.

Constipation is a very common problem affecting an estimated 80% of people at some time during their lives.* Most often constipation affects women and adults 65 years of age and older; however, men and children can be constipated as well.

Irritable Bowel Syndrome with Constipation (IBS-C) is a disorder that interferes with the normal functions of the large intestine (colon). IBS-C is characterized by the following symptoms:

  • Abdominal pain or discomfort
  • Bloating and/or straining
  • Hard or lumpy stools
  • Infrequent bowel movements

There are other forms of Irritable Bowel Syndrome (IBS), including:

  • IBS-D which is diarrhea-predominant and the main symptoms include pain and diarrhea
  • IBS-M which is alternating symptoms or mixed symptoms of constipation and diarrhea including pain
  • IBS-U which is IBS that does not fit into any of the other three subtypes
  • IBS is the most common gastrointestinal disorder seen by doctors; as many as one in five American adults have IBS.

For this study, we are looking for participants with the symptoms of Irritable Bowel Syndrome with Constipation only.

There is no known cure for IBS-C; however, there are methods you can try to help with symptoms:

  • Increasing your intake of dietary fiber
  • Increasing water or non-caffeinated beverage consumption
  • Increasing physical activity

IBS-C should not be ignored. If you have tried lifestyle changes and other therapies without relief, consider other options.

Although most constipation is temporary, sometimes it is chronic or long-standing. Understanding its causes, prevention and treatment may help in finding relief.
