What is IBS-D?

Prevalence of IBS in the United States

Irritable Bowel Syndrome is a collection of symptoms that appear together without the presence of damage or disease to the digestive tract. Individuals with IBS experience abdominal pain and changes to their bowel movements that include diarrhea, constipation, or both.

It is estimated that about 12% of the US population suffers from IBS. Factors that increase the likelihood of developing IBS include a family history of IBS, a history of stressful life events, and severe infection of the digestive tract.

The subtype of IBS known as Irritable Bowel Syndrome with Persistent Diarrhea (IBS-D) is defined by abnormal bowel movement where more than a quarter of stools are loose and watery.

Current therapy options include prescription medications, stress management, and dietary supplements. Enviva is researching an investigational drug that works differently than currently approved medications and has potential to help relieve unpleasant symptoms.
