Learn About Chronic Idiopathic Constipation (CIC)

What is the definition of Chronic Idiopathic Constipation (CIC)?
Chronic idiopathic (of unknown cause) constipation is a persistent condition that mainly affects females and older adults and is characterized by infrequent, hard, and lumpy stools that are extremely difficult to pass. This creates a buildup of stool in the colon that causes extreme abdominal and pelvic pain. While the cause is unknown, chronic idiopathic constipation may be triggered by reduced fluid and fiber intake; the use of certain medications, such as antihistamines, antipsychotic medications, opioids, general anesthetics, and antiparkinsonian drugs; changes in the colon; rectocele (rectum bulging into vagina); rectal prolapse (rectum protrudes through the anus); or dyssynergic dysfunction (disorder of muscles and sphincters that control defecation).
What are the symptoms of Chronic Idiopathic Constipation (CIC)?
Symptoms of chronic idiopathic constipation may include chronic constipation (fewer than three bowel movements a week) that persists for six months or more with hard stools; a feeling of incomplete bowel evacuation; a sensation of a blockage in the rectum or anus; straining upon defecation; abdominal pain and bloating; back pain; poor appetite; a general feeling of being unwell (malaise); and the necessity of using the hands to facilitate defecation.
